  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing. However, the embodiments described below are given various technically preferable limitations for carrying out the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[First Embodiment]
FIG. 1 is a perspective view showing a usage state of the projection apparatus 1.
The projection apparatus 1 is an electronic device. An external device 99 is connected to the projection apparatus 1. The video generated by the external device 99 is transferred as a video signal from the external device 99 to the projection apparatus 1, and the video 98 based on the video signal is projected on the screen by the projection apparatus 1. The brightness (brightness) of the projection light 96 of the image 98 can be adjusted by the projection device 1. That is, the user 90 can increase or decrease the brightness of the projection light 96 by operating the operation unit 6 of the projection apparatus 1.

  The user 90 can adjust the brightness of the projection light 96 stepwise by operating the operation unit 6 of the projection apparatus 1, and there are a plurality of user setting options relating to the brightness of the projection light 96. That is, there are a plurality of options as setting conditions for the operation of the projection apparatus 1. Specifically, the brightness of the projection light 96 can be adjusted in two steps, and user setting options relating to the brightness of the projection light 96 include a high brightness setting (first option) and a low brightness setting (second option). . When the user 90 sets the user setting to the high luminance setting (high luminance mode) by operating the operation unit 6, the projection device 1 projects the high luminance projection light 96. On the other hand, when the user 90 sets the user setting to the low luminance setting (low luminance mode) by operating the operation unit 6, the projection device 1 projects the low luminance projection light 96. The projection light 96 in the high luminance setting has higher luminance than the projection light 96 in the low luminance setting. Note that the present invention does not limit the number of user-set steps relating to the luminance of the projection light 96 to two.

  The high luminance setting is a high power consumption setting, and the low luminance setting is a low power consumption setting. That is, the power consumption of the projection apparatus 1 when the user setting relating to the luminance of the projection light 96 is selected as the high luminance setting is the power consumption of the projection apparatus 1 when the user setting relating to the luminance of the projection light 96 is selected as the low luminance setting. Higher than power consumption.

  The projection device 1 includes a storage battery (secondary battery) 7 that can be charged. The projection device 1 operates using the power of the storage battery 7. When an external power source (for example, a commercial power source supplied from a power company or a power transmission company) 91 is connected to the projection apparatus 1, power is supplied from the external power source 91 to the projection apparatus 1, and the storage battery 7 of the projection apparatus 1 is While being charged, the projection apparatus 1 operates using the power of the external power supply 91.

  If the remaining amount stored in the storage battery 7 is large, the user setting options relating to the brightness of the projection light 96 are not limited. That is, in the user setting relating to the luminance of the projection light 96, selection of high luminance setting and selection of low luminance setting are permitted. Therefore, when the user operates the operation unit 6, either the high luminance setting or the low luminance setting can be selected as the user setting relating to the luminance of the projection light 96.

  On the other hand, when the remaining amount stored in the storage battery 7 is small, the user setting options relating to the brightness of the projection light 96 are limited. That is, in the user setting relating to the luminance of the projection light 96, the selection of the low luminance setting is permitted, but the selection of the high luminance setting is prohibited. Therefore, when the user operates the operation unit 6, the low luminance setting can be selected as the user setting related to the luminance of the projection light 96, but the high luminance setting cannot be selected.

  Whether the storage battery 7 has a large amount of remaining power (remaining charge) is determined based on a predetermined threshold. That is, if the remaining amount stored in the storage battery 7 exceeds a predetermined threshold, selection of high brightness setting and low brightness setting is permitted in the user setting regarding the brightness of the projection light 96. On the other hand, if the remaining amount stored in the storage battery 7 is equal to or less than a predetermined threshold value, the selection of the low luminance setting is permitted in the user setting relating to the luminance of the projection light 96, but the selection of the high luminance setting is prohibited. In other words, the predetermined threshold is a criterion for determining whether or not an option can be selected, and is used to distinguish the option. The high luminance setting corresponds to a value exceeding a predetermined threshold value, and the low luminance setting corresponds to a value equal to or less than the predetermined threshold value. Since the remaining amount stored in the storage battery 7 can be converted into the remaining time during which the projection apparatus 1 can operate with the remaining amount of storage, the remaining amount of storage corresponds to the remaining time, and the threshold value is time. Is converted to a threshold value in units.

  When the remaining power level of the storage battery 7 falls below a predetermined threshold with the user setting of the brightness of the projection light 96 being selected as the high brightness setting during the operation of the projection apparatus 1, the projection apparatus 1 Operates as either (1) or (2).

(1) The user setting relating to the luminance of the projection light 96 is automatically changed to the low luminance setting, and the luminance of the projection light 96 is lowered. After that, as long as the remaining amount of electricity stored in the storage battery 7 does not exceed a predetermined threshold, it is prohibited to select the high brightness setting.

(2) The user setting relating to the luminance of the projection light 96 is maintained at the high luminance setting, and the luminance of the projection light 96 is maintained at the high luminance. Then, when the user 90 operates the operation unit 6 to select the low brightness setting, thereafter, the high brightness setting is prohibited from being selected unless the remaining power of the storage battery 7 exceeds a predetermined threshold.

  When adjusting the brightness of the projection light 96, a user setting display area 97 is displayed in the video 98. The user setting display area 97 is generated by the projection apparatus 1. That is, the user setting display area 97 is displayed in the video 98 by superimposing a signal for displaying the user setting display area 97 on the video signal.

  The user setting display area 97 displays a plurality of user setting options (high luminance setting and low luminance setting) regarding the luminance of the projection light 96. Among the options, the currently selected option and the unselected option are identified and displayed. Specifically, a color or pattern other than white is added to the background of the selected option, and white is added to the background of the option that is not selected.

  Of the choices displayed in the user setting display area 97, the choices permitted to be selected and the choices prohibited from being selected are identified and displayed. For example, characters representing options that are permitted to be selected are displayed in black, and characters representing options that are prohibited from being selected are displayed in gray or translucent.

  Therefore, the brightness of the projection light 96 can be adjusted by the user 90 operating the operation unit 6 while viewing the user setting display area 97. The display content of the user setting display area 97 is displayed on a display device (for example, a liquid crystal display) or a signal lamp (for example, a light emitting diode that blinks, lights up, or turns off according to the display content) provided in the projection device 1. May be.

  The projection apparatus 1 can adjust the image tone (image quality) of the video 98. The user 90 can adjust the image tone of the video 98 by operating the operation unit 6 of the projection apparatus 1. The image tones that can be set are cinematic, sports watching, photo, game, and computer graphic. In other words, there are cinema-like, sports watching-like, photo-like, game-like, and computer graphic-like options as user setting options relating to the picture tone.

  The power supply device 9 is a stabilized power supply that keeps the DC output voltage constant. That is, the power supply device 9 reduces the voltage of the AC power input from the external power supply 91, converts the AC power into DC power having a constant voltage, and outputs the DC power to the charging control unit 8. The power supply device 9 may be provided in the housing of the projection device 1 or may be provided outside the housing. When the power supply device 9 is provided outside the projection device 1, the power supply device 9 is connected to the charging control unit 8 by wiring. When the power supply device 9 is not connected to the external power supply 91, DC power is not supplied from the power supply device 9 to the charging control unit 8.

  The charging control unit 8 is a circuit that controls charging / discharging of the storage battery 7. That is, the charging control unit 8 supplies a part of the DC power supplied from the power supply device 9 to each unit of the projection device 1 (system controller 3, program memory 4, operation unit 6, projection device main unit 2, etc.). Then, the storage battery 7 is charged with a part of the DC power supplied from the power supply device 9. When DC power is not supplied from the power supply device 9 to the charging control unit 8, the charging control unit 8 converts the power charged in the storage battery 7 to each unit (system controller 3, program memory 4, operation unit 6, and projection) of the projection device 1. To the main body 2).

The charge control unit 8 detects the remaining amount of electricity stored in the storage battery 7 and outputs a signal representing the remaining amount of electricity stored (hereinafter referred to as a remaining amount signal) to the system controller 3. That is, the charging control unit 8 is a remaining power storage detection unit.
In addition, the charging control unit 8 has a signal indicating whether or not DC power is supplied from the power supply device 9 (that is, a signal indicating whether or not charging is being performed. Hereinafter, it is referred to as a charging presence / absence signal). Output to the controller 3. When DC power is supplied from the power supply device 9 to the charge control unit 8, the charge presence / absence signal indicates “1 (during charging)”, and DC power is not supplied from the power supply device 9 to the charge control unit 8. In this case, the charge presence / absence signal indicates “zero (not charging)”.

  The operation unit 6 is an input device that receives input from the user 90, and includes, for example, a plurality of switches (push buttons) or a dial. When the user 90 operates the operation unit 6, the operation unit 6 outputs a signal corresponding to the operation content to the system controller 3 wirelessly or by wire. The operation unit 6 is provided in the housing of the projection apparatus 1 or is provided separately from the housing.

  The projector main unit 2 receives the video signal output by the external device 99 and projects a video based on the video signal on the screen. The projection apparatus main body 2 includes a video input terminal 21, a video signal conversion unit 22, a video signal processing unit (scaler) 23, a display controller 24, a display element 25, a light source control unit 26, a light source device 27, a projection lens 28, and the like. Have.

  The projection apparatus main body 2 is a DMD type projection apparatus main body, an LCD type projection apparatus main body, or an LCOS (LCOS (trade name) type) projection apparatus main body. The DMD type projector main body uses a DMD (digital micromirror device) for the display element 25. The LCD-type projector main body uses a transmissive LCD panel (liquid crystal display element panel) as the display element 25. The LCOS type projector main body uses a reflective LCD panel for the display element 25.

  A video input terminal 21 is provided on the housing of the projection apparatus 1. The video output terminal of the external device 99 is connected to the video input terminal 21 via the video signal cable 99a (see FIG. 1), and the video signal output by the external device 99 is input to the video input terminal 21.

  The video signal conversion unit 22, the video signal processing unit 23, the display controller 24, the display element 25, the light source control unit 26, and the light source device 27 are provided in the casing of the projection device 1. The video signal converter 22 converts the analog video signal input from the video input terminal 21 into a digital video signal, and converts the digital video signal or the digital video signal input into the video input terminal 21 into a predetermined format. .

  The video signal processing unit 23 performs various types of signal processing on the video signal output by the video signal conversion unit 22. For example, the video signal processing unit 23 receives a signal for displaying the user setting display area 97 (see FIG. 1) (this signal is generated by the system controller 3) from the system controller 3, and converts the signal into a video signal. The user setting display area 97 is combined with the video 98 by being superimposed on the video signal input from the unit 22. Further, the video signal processing unit 23 scales the video signal input from the video signal conversion unit 22 to increase or decrease the number of pixels (resolution) of the video signal. The video signal processing unit 23 performs keystone correction, fitting correction, or both by performing coordinate conversion (for example, projective conversion) of video based on the scaled video signal. The video signal processed by the video signal processing unit 23 is transferred to the display controller 24.

  The display element 25 is a spatial light modulation element, more specifically a DMD, a transmissive LCD panel, or a reflective LCD panel. The display element 25 has a plurality of pixels arranged in a two-dimensional array. When the display element 25 is a DMD, the pixel of the display element 25 is a movable micromirror, and when the display element 25 is a transmissive LCD panel or a reflective LCD panel, the pixel of the display element 25 is a liquid crystal element. It is.

  The display controller 24 drives the display element 25 based on the video signal input from the video signal processing unit 23. For example, when the display controller 24 performs PWM control or PNM control for each pixel of the display element 25 according to the video signal input from the video signal processing unit 23, the light irradiated to the display element 25 is modulated for each pixel by the pixel. The Thereby, an image is formed by the display element 25.

  The number of display elements 25 is one or plural (for example, three).

  The light source device 27 emits visible light toward the display element 25. Specifically, the light source device 27 is of a time division type or a color separation type.

  When the light source device 27 is a color separation system, the light source device 27 has a white light source, a color separator, and the like, and white light emitted from the white light source has a plurality of colors (for example, red, green, blue) by the color separator. Separated into light. In this case, the number of the display elements 25 is plural, the display elements 25 generate images of the respective colors, the light of each color is irradiated on the display elements 25, and the light of each color transmitted or reflected by the display elements 25, respectively. Is synthesized. The synthesized projection light 96 is projected onto the screen by the projection lens 28, so that a color image 98 appears on the screen.

  When the light source device 27 is a time-division method, the light source device 27 sequentially irradiates the display element 25 with visible light of different colors (for example, red light, green light, and blue light), and one cycle of the repetition is This corresponds to a period in which a color image of one frame is generated by the display element 25. In this case, the number of display elements 25 is one, and the display elements 25 sequentially generate images of different colors. More specifically, the display element 25 generates an image having the same color as the light emitted by the light source device 27 in synchronization with the light emission timing. The light of each color transmitted or reflected by the display element 25 is combined with time, and the combined projection light 96 is projected onto the screen by the projection lens 28, whereby a color image 98 is displayed on the screen.

  When the light source device 27 is a time division method, the light source device 27 is a color filter method or a color light source method. When the light source device 27 is a color filter system, the light source device 27 has a color filter, a spindle motor, a white light source, and the like, the color filter is rotated by the spindle motor, and the white light emitted from the white light source is rotating. The white light passes through each color (red, green, blue) and is sequentially converted. When the light source device 27 is a color light source system, the light source device 27 has a plurality of light sources of different colors (for example, a red light source, a green light source, and a blue light source), and these light sources are repeatedly turned on sequentially.

  The light source used for the light source device 27 is a semiconductor light emitting element (for example, laser diode, light emitting diode) or a lamp (for example, halogen lamp, xenon lamp, metal halide, mercury lamp, discharge lamp), or a semiconductor light emitting element or lamp. And a combination of phosphors.

  The light source control unit 26 controls the luminance of the light source device 27. That is, the system controller 3 outputs a dimming signal representing the luminance to the light source control unit 26, and the light source control unit 26 causes the light source device 27 to emit light with luminance according to the dimming signal input from the system controller 3.

  Further, when the light source device 27 is a time division method, the light source control unit 26 controls the emission timing of each color light of the light source device 27 based on the timing signal input from the display controller 24. Thereby, the light emitted from the light source device 27 is synchronized with the timing at which the display element 25 generates the same color image.

  The projection lens 28 can be adjusted for focusing and focal length.

The system controller 3 is an arithmetic processing unit (computer) having a CPU and a storage device.
The program memory 4 is a nonvolatile semiconductor memory or a magnetic storage device. A program 5 is stored in the program memory 4.
The system controller 3 reads the program 5 by accessing the program memory 4. The system controller 3 executes processing according to the program memory 4. Accordingly, the system controller 3 controls the video signal processing unit 23, the display controller 24, and the light source control unit 26 in an integrated manner.

  Subsequently, processing executed by the system controller 3 based on the program 5 will be described.

  FIG. 3 is a flowchart of permission / rejection determination processing. First, the system controller 3 determines the presence or absence of charging based on the charging presence / absence signal input from the charging control unit 8 (step S1). At this time, when power is supplied from the power supply device 9 to the charging control unit 8 (step S1: YES), the system controller 3 permits selection of the high luminance setting and the low luminance setting among the options (step S1). S3), storing that the selection of the high luminance setting and the low luminance setting is permitted. Thereafter, the processing of the system controller 3 returns to step S1.

  On the other hand, when power is not being supplied from the power supply device 9 to the charging control unit 8 (step S1: NO), the system controller 3 performs the projection apparatus main body based on the remaining power storage amount detected by the charging control unit 8. Whether to allow selection of user setting options (high luminance setting and low luminance setting) regarding the output luminance of the unit 2 (particularly the light source device 27) is determined (see step S3 to step S5).

  That is, first, the system controller 3 compares the remaining power amount detected by the charge control unit 8 with a predetermined threshold (step S3). That is, the system controller 3 compares the level of the remaining amount signal output by the charge control unit 8 with a predetermined threshold value.

  As a result of the comparison, when the system controller 3 determines that the remaining power storage exceeds the predetermined threshold (step S3: YES), the system controller 3 permits the selection of the high luminance setting and the low luminance setting among the options (step S3). S4). Then, the system controller 3 stores that the selection of the high luminance setting and the low luminance setting is permitted. Thereafter, the processing of the system controller 3 returns to step S1.

  On the other hand, as a result of the comparison, when the system controller 3 determines that the remaining amount of power storage is equal to or less than the predetermined threshold (step S3: NO), the system controller 3 permits the selection of the low luminance setting among the options, and the high luminance Setting selection is prohibited (step S5). Then, the system controller 3 stores that the selection of the low luminance setting is permitted and the selection of the high luminance setting is prohibited. Thereafter, the processing of the system controller 3 returns to step S1.

  The system controller 3 repeatedly executes the permission / rejection determination process shown in FIG.

Regardless of whether or not power is supplied from the power supply device 9 to the charging control unit 8, when the user 90 inputs a user setting mode command by operating the operation unit 6, the system controller 3 executes user setting processing. The user setting process is performed after the process shown in FIG. 3 is performed once or more. However, since the permission determination process is repeatedly performed, the user setting process may be performed in parallel with the permission determination process. Note that user setting processing may be performed following steps S2, S4, and S5 of FIG.
The user setting process is a process for selecting one of the user setting options regarding the output luminance of the projection apparatus main body 2 (particularly, the light source device 27). The user setting process will be specifically described below.

  First, the system controller 3 generates a display signal for the user setting display area 97 and outputs the display signal to the video signal processing unit 23. Thereby, the display signal of the user setting display area 97 is superimposed on the video signal by the video signal processing unit 23, and the user setting display area 97 is combined with the projected video 98.

  At this time, the system controller 3 determines a display mode of a plurality of options (high luminance setting and low luminance setting) based on the storage result by the permission determination process shown in FIG. 3, and a user setting display area according to the display mode 97 display signals are generated. Specifically, the selection is permitted (high luminance setting and low luminance setting in the case of step S2 or step S4, and low luminance setting in the case of step S5), and the selection is prohibited. The system controller 3 generates a display signal in which a display mode is identifiable from the options (there are no prohibited options in the case of step S2 or step S4 and the high brightness setting in the case of step S5). The display signal is output to the video signal processing unit 23. That is, a notification is given so that the option forbidden by the permission determination means and the option permitted for the selection can be identified. It should be noted that the display mode may be such that the selection permitted is displayed in the user setting display area 97 and the selection prohibited is not displayed in the user setting display area 97.

  Thereafter, the user 90 operates the operation unit 6 to select one of the options (one of the high luminance setting and the low luminance setting). That is, when the user 90 operates the operation unit 6, a signal corresponding to the operation content is output to the system controller 3, and the system controller 3 selects any one option based on the signal. At this time, the system controller 3 does not accept selection of an option that is prohibited by the result of the permission / refusal determination process shown in FIG. 3, but accepts selection of an option permitted by the result of the permission / refusal determination process shown in FIG. .

  Then, the system controller 3 outputs a dimming signal representing the luminance according to the selected option to the light source control unit 26. Then, the light source control unit 26 causes the light source device 27 to emit light with a luminance corresponding to the dimming signal input from the system controller 3. That is, when the user setting regarding the output brightness of the projection apparatus main body 2 is set to the high brightness setting by the operation of the operation unit 6 by the user 90, the light source device 27 emits light with high brightness, and the high brightness projection light 96. Is projected. When the user setting relating to the output luminance of the projection apparatus main body 2 is set to the low luminance setting by the operation of the operation unit 6 by the user 90, the light source device 27 emits light with low luminance and the low luminance projection light 96 is emitted. Is projected. Note that, regardless of whether the user setting is set to the high luminance setting or the low luminance setting by the operation of the operation unit 6 by the user 90, the system controller 3 stores the contents of the user setting.

  According to this embodiment, the following effects occur.

(A) If the remaining amount of electricity stored in the storage battery 7 is small, the selection of the high brightness setting is prohibited in the user setting, so that the usable time of the projection apparatus 1 can be extended.

(B) If the remaining amount of power stored in the storage battery 7 is large, the selection of the high brightness setting is permitted in the user setting, so that the projection device 96 can be used comfortably by brightening the projection light 96.

(C) The customization variation can be changed according to the amount of remaining power in the storage battery 7. In other words, if the storage battery 7 has a large amount of remaining power, the user setting allows the selection of the high brightness setting and the low brightness setting. If the storage battery 7 has a small amount of storage, the user setting prohibits the selection of the high brightness setting. In addition, since the selection of the low luminance setting is permitted, the customization variation related to the brightness when the storage battery 7 has a large amount of remaining power and the customization variation related to the brightness when the storage battery 7 has a small remaining charge can be made different. it can.

[Modification 1]
In the above-described embodiment, the brightness of the projection light 96 can be adjusted in two steps, but it may be adjustable in three or more steps. That is, the number of user setting options related to the output luminance of the projection apparatus main body 2 is two, but may be three or more. In this case, the number of thresholds to be compared with the remaining amount of electricity stored is a value obtained by subtracting 1 from the number of options, and these thresholds are prepared in stages.

  For example, when the brightness of the projection light 96 can be adjusted in three stages, there are high brightness setting, medium brightness setting, and low brightness setting as user setting options relating to the output brightness of the projection apparatus main body unit 2 and detected. The remaining amount of electricity stored is compared by the system controller 3 with a high threshold and a low threshold (high threshold> low threshold). If the detected remaining power level exceeds the high threshold, the user setting allows selection of high brightness setting, medium brightness setting, and low brightness setting, and the detected remaining power level exceeds the low threshold and is high. If the threshold value is less than or equal to the threshold value, selection of the medium luminance setting and the low luminance setting is permitted in the user setting, and selection of the high luminance setting is prohibited. In the setting, the selection of the low luminance setting is permitted, and the selection of the high luminance setting and the medium period setting is prohibited.

[Modification 2]
Based on the remaining amount of electricity detected by the charge controller 8, the system controller 3 selects user settings relating to execution of ROM update (system program update) (for example, first option: automatic execution of ROM update, second It may be determined whether or not to allow selection of an option: manual execution of ROM update and a third option: prohibition of ROM update execution. For example, if the remaining amount of electricity detected by the charge control unit 8 exceeds the high threshold, it is permitted to select the first option to the third option by the user setting. If the remaining amount of electricity detected by the charge controller 8 is less than or equal to the high threshold and exceeds the low threshold (however, the high threshold> the low threshold), it is permitted to select the second option and the third option in the user settings. Thus, the selection of the first option in the user setting is prohibited. If the remaining amount of electricity detected by the charge control unit 8 is less than or equal to the low threshold, the user is allowed to select the third option in the user setting, and can select the first option and the second option in the user setting. It is forbidden.

[Modification 3]
Based on the remaining amount of electricity detected by the charge controller 8, the system controller 3 selects user settings related to the on / off setting of the gesture sensor (for example, the first option: the gesture sensor is turned on, the second option: the gesture It may be determined whether the sensor is set to off. For example, if the remaining amount of electricity detected by the charge control unit 8 exceeds a threshold value, it is permitted to select the first option and the second option by user setting, and the remaining amount of electricity detected by the charge control unit 8 Is equal to or less than the threshold, the user setting allows the second option to be selected and the first option to be prohibited.

[Second Embodiment]
The same code | symbol is attached | subjected to what mutually respond | corresponds between 2nd Embodiment and 1st Embodiment.

  The projection apparatus 1 according to the second embodiment is configured similarly to the projection apparatus 1 according to the first embodiment (see FIG. 2). However, the program 5 stored in the program memory 4 according to the second embodiment is different from the program 5 stored in the program memory 4 according to the first embodiment. Further, the process executed by the system controller 3 according to the program 5 in the second embodiment is different from the process executed by the system controller 3 according to the program 5 in the first embodiment.

  In the first embodiment, the user setting relates to the output luminance of the projection apparatus main body 2 (particularly, the light source device 27), and whether or not the user setting option is acceptable is determined based on the remaining amount of power stored in the storage battery 7. On the other hand, in the second embodiment, the user setting is related to the time measurement (set time), and whether or not the user setting option is acceptable is determined based on the remaining power storage amount of the storage battery 7.

  FIG. 4 is a perspective view showing a usage state of the projection apparatus 1 according to the second embodiment.

  The user 90 performs projection using an image 98 projected by the projection apparatus 1. In the video 98, a display time 95 during counting is displayed. The display time 95 is displayed by the projection apparatus 1. That is, the display time 95 is displayed in the video 98 by superimposing a signal for displaying the display time 95 on the video signal by the projection apparatus 1. A timekeeping function is mounted on the projection apparatus 1, and a display time 95 represents the time counted by the projection apparatus 1. The numerical value of the display time 95 changes with time.

  If the time is counted up, the display time 95 represents the time from the time starting time (particularly the lecture start time) to the current time. If the time is a countdown time, the display time 95 is the current time. Represents the time from the time until the end of time (especially the scheduled end time). Therefore, the user 90 can make a lecture while recognizing the time from the start of the lecture and the remaining time of the lecture by visually confirming the display time 95.

  The user can increase or decrease the time keeping time (set time) stepwise by operating the operation unit 6 of the projection apparatus 1 before the start of time keeping, and there are a plurality of user setting options relating to the time keeping time. Specifically, the timekeeping time can be increased / decreased in four stages, and the first setting time (first option), the second setting time (second option), the third setting time ( There is a third option) and a fourth set time (fourth option). The values of the first setting time, the second setting time, the third setting time, and the fourth setting time are different from each other and satisfy “first setting time> second setting time> third setting time> fourth setting time”. For example, the first setting time, the second setting time, the third setting time, and the fourth setting time are 100 minutes, 80 minutes, 60 minutes, and 40 minutes, respectively. When the user 90 sets the first setting time in the user setting by operating the operation unit 6, the first setting time is measured by the projection device 1, and the display time 95 during the measurement is displayed on the video 98. Is displayed. The same applies to the second set time, the third set time, or the fourth set time. However, the present invention does not limit the number of user setting steps relating to time keeping to four steps.

  Note that the longer the set time is, the longer the time that the projection apparatus 1 must be driven and the higher the power consumption value. That is, the magnitude of the power consumption value due to the selection of each set time is first set time> second set time> third set time> fourth set time.

The degree of the remaining amount of electricity stored in the storage battery 7 is determined based on a predetermined threshold, and whether or not an option is selected is determined based on a comparison between the remaining amount of electricity stored in the storage battery 7 and the predetermined threshold (see the following table).

As shown in Table 1 above, if the remaining amount stored in the storage battery 7 exceeds the first threshold value, the first setting time, the second setting time, the third setting time, and the fourth setting time in the user setting related to the timekeeping time Selection is allowed.
Further, if the remaining amount stored in the storage battery 7 is equal to or less than the first threshold and exceeds the second threshold (where the first threshold> the second threshold), the second set time, the third set time, Selection of the fourth set time is permitted, but selection of the first set time is prohibited.
Further, if the remaining amount stored in the storage battery 7 is equal to or lower than the second threshold and exceeds the third threshold (however, the second threshold> the third threshold), the third set time and the fourth set time are set in the user setting relating to the time count. Selection is permitted, but selection of the first set time and the second set time is prohibited.
In addition, if the remaining amount stored in the storage battery 7 is equal to or less than the third threshold and exceeds the fourth threshold (however, the third threshold> the fourth threshold), the selection of the fourth setting time is permitted in the selection of the user setting relating to the time measurement time. However, selection of the first set time, the second set time, and the third set time is prohibited.
Further, if the remaining amount stored in the storage battery 7 is equal to or less than the fourth threshold, selection of the first set time, the second set time, the third set time, and the fourth set time is prohibited in the user setting related to the time measurement time. .

Since the remaining amount stored in the storage battery 7 can be converted into the remaining time during which the projection apparatus 1 can operate with the remaining amount of stored electricity, the remaining amount of storage corresponds to the remaining time. Further, since the charge control unit 8 detects the remaining amount stored in the storage battery 7, the charge control unit 8 corresponds to a conversion unit (converting unit) that converts the detected remaining amount into the remaining time in which the projection apparatus 1 can operate. To do.
Here, when the first threshold value is converted into the remaining time in which the projection apparatus 1 can operate with the remaining power amount of the first threshold value, the converted value is equal to the first set time. That is, that the remaining amount stored in the storage battery 7 exceeds the first threshold corresponds to the remaining operating time of the projection device 1 exceeding the first set time, and the remaining amount stored in the storage battery 7 is the first. That it is 1 threshold value or less is equivalent to the remaining operable time of the projection apparatus 1 being 1st set time or less. Similarly, when the second threshold value is converted into the remaining time, the converted value is equal to the second set time. When the third threshold value is converted into the remaining time, the converted value is equal to the third set time. When the fourth threshold value is converted into the remaining time, the converted value is equal to the fourth set time.

The following table summarizes the relationship between the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the first set time, the second set time, the third set time, and the fourth set time.

  As described above, when the remaining operable time of the projection apparatus 1 exceeds the first set time (when the remaining amount stored in the storage battery 7 exceeds the first threshold), the first user setting related to the time measurement time is used. Selection of set time is allowed. Therefore, even when the user setting is set to the first set time and the time measurement of the first set time is started, the time measurement is finished before the remaining amount stored in the storage battery 7 runs out. That is, it is possible to prevent the projection apparatus 1 from being out of charge before the timing of the first set time is completed. The same applies to the case where the remaining operable time of the projection apparatus 1 exceeds the second set time, the third set time, or the fourth set time.

  When increasing or decreasing the timed time (set time), a user setting display area 97 as shown in FIG. In the user setting display area 97, a plurality of user setting options (first setting time, second setting time, third setting time, and fourth setting time) relating to time keeping time are displayed ("timer setting" shown in FIG. 5). See the "Time" line). Among the options, the currently selected option and the unselected option are identified and displayed. Specifically, a color or pattern other than white is added to the background of the selected option, and white is added to the background of the option that is not selected.

  Of the choices displayed in the user setting display area 94, the choices permitted to be selected and the choices prohibited from being selected are identified and displayed. For example, characters representing options that are permitted to be selected are displayed in black, and characters representing options that are prohibited from being selected are displayed in gray or translucent.

  When the user 90 operates the operation unit 6 while looking at the user setting display area 97, the time count can be increased or decreased.

  In the user setting display area 97, a timer start icon and a timer reset icon are displayed. When the user 90 selects the timer start icon or the timer reset icon by operating the operation unit 6, the time measurement of the selected option (any one of the first to fourth setting times) is started or the time measurement is reset. The

  In the user setting display area 97, options (“upper left”, “lower left”, “upper right”, “lower right”) regarding the display position of the display time 95 (see FIG. 4) are displayed. When the user 90 selects an option by operating the operation unit 6 while looking at the user setting display area 97, a display time 95 is displayed at the position of the selected option.

  Subsequently, processing executed by the system controller 3 based on the program 5 will be described. FIG. 6 is a flowchart of a main routine of determination processing executed by the system controller 3.

  As shown in FIG. 6, the system controller 3 determines the presence / absence of charging based on the charging presence / absence signal input from the charging control unit 8 (step S <b> 101). At this time, when power is supplied from the power supply device 9 to the charging control unit 8 (step S101: YES), the system controller 3 permits selection of the first to fourth set times, and the first to first settings. The fact that the selection of the set time of 4 is permitted is stored (step S102). Thereafter, the processing of the system controller 3 returns to step S101.

On the other hand, when the power is not supplied from the power supply device 9 to the charging control unit 8 (step S101: NO), the system controller 3 executes the permission determination process of FIG. 6 (step S100, The process of the system controller 3 returns to step S101.
Therefore, the system controller 3 repeatedly executes the permission / refusal determination process shown in FIG.

  Next, permission / rejection determination processing will be described. In addition, the comparison between the remaining amount of storage and the first threshold (S101A to S103A), the comparison between the remaining amount of storage and the second threshold (S101B to S103B), the comparison between the remaining amount of storage and the third threshold (S101C to S103C), The process of comparing the remaining power storage amount with the fourth threshold value (S101D to S103D) may be sequentially performed in a predetermined order different from the present embodiment, or the comparison between the remaining power storage amount and the first threshold value (S101A to S103A). ), The comparison between the remaining amount of storage and the second threshold (S101B to S103B), the comparison between the remaining amount of storage and the third threshold (S101C to S103C), and the comparison between the remaining amount of storage and the fourth threshold (S101D to S103D). The processes may be executed by the system controller 3 in parallel.

  As shown in FIG. 6, the system controller 3 selects user setting options (first setting time, second setting time, third setting time, and time setting time) based on the remaining power storage amount detected by the charging control unit 8. Whether to select the fourth set time is determined (see Step S101A to Step S103A, Step S101B to Step S103B, Step S101C to Step S103C, Step S101D to Step S103D).

  With reference to FIG. 7, the process for determining whether or not to allow selection of the first set time as an option will be described in detail. The first threshold value is used when determining whether to permit selection of the first set time. That is, the system controller 3 compares the remaining power amount detected by the charge control unit 8 with the first threshold value (step S101A).

  As a result of the comparison, when the system controller 3 determines that the remaining amount of power storage exceeds the first threshold (step S101A: YES), the system controller 3 permits selection of the first set time (step S102A). Then, the system controller 3 stores that the selection of the first set time is permitted. And it progresses to the step (S101B) which compares the electrical storage residual amount detected by the charge control part 8 with a 2nd threshold value.

  On the other hand, as a result of the comparison, when the system controller 3 determines that the remaining amount of power storage is equal to or less than the first threshold (step S101A: NO), the system controller 3 prohibits selection of the first set time (step S103A). . Then, the system controller 3 stores that the selection of the first set time is prohibited. And it progresses to the step (S101B) which compares the electrical storage residual amount detected by the charge control part 8 with a 2nd threshold value.

  The second threshold is used when determining whether to permit selection of the second set time, the third threshold is used when determining whether to allow selection of the third set time, and when determining whether to permit selection of the fourth set time. A fourth threshold is used. As shown in FIG. 6, the system controller 3 compares the remaining power storage amount detected by the charge control unit 8 with the second threshold value, the third threshold value, and the fourth threshold value in order, so that the second set time, the third set time, and The process of determining whether or not to select the fourth set time is a process in which the system controller 3 determines whether or not to select the first set time by comparing the remaining power amount detected by the charge control unit 8 with the first threshold. Is the same. That is, Step S101B to Step S103B, Step S101C to Step S103C, and Step S101D to Step S103D correspond to Step S101A to Step S103A, respectively.

Regardless of whether or not power is supplied from the power supply device 9 to the charging control unit 8, when the user 90 inputs a user setting mode command by operating the operation unit 6, the system controller 3 executes user setting processing. The user setting process is performed after the process shown in FIG. 6 is performed once or more. However, since the process shown in FIG. 6 is repeatedly performed, the user setting process may be performed in parallel with the permission determination process (step S100). Note that user setting processing may be performed following steps S102, S102D, and S103D of FIG.
The user setting process is a process for selecting one of the user setting options (first setting time, second setting time, third setting time, and fourth setting time) related to the time keeping time. The user setting process will be specifically described below.

  First, the system controller 3 generates a display signal for the user setting display area 94 and outputs the display signal to the video signal processing unit 23. Thereby, the display signal of the user setting display area 94 is superimposed on the video signal by the video signal processing unit 23, and the user setting display area 94 is combined with the projected video 98.

  At this time, the system controller 3 selects a plurality of options (first setting time, first setting time, S103D) based on the storage results (see steps S102, 102A, S103A, S102B, S103B, S102C, S103C, S102D, and S103D) shown in FIG. The display mode of the second setting time, the third setting time, and the fourth setting time is determined, and the display signal of the user setting display area 94 according to the display mode is generated. Specifically, the system controller 3 generates a display signal that makes it possible to discriminate between an option that is allowed to be selected and an option that is prohibited from being selected, and the display signal is sent to the video signal processing unit 23. Output. That is, a notification is given so that the option forbidden by the permission determination means and the option permitted for the selection can be identified. Note that the display mode may be such that the selection permitted is displayed in the user setting display area 94 and the selection prohibited is not displayed in the user setting display area 94.

  Thereafter, the user 90 operates the operation unit 6 to select any one option. That is, when the user 90 operates the operation unit 6, a signal corresponding to the operation content is output to the system controller 3, and the system controller 3 selects any one option based on the signal. At this time, the system controller 3 does not accept selection for an option that is prohibited based on the result of the permission / refusal determination process shown in FIG. 6, but accepts selection for an option that is permitted based on the result of the permission / rejection determination process shown in FIG. .

  Then, when the user 90 selects the timer start icon by operating the operation unit 6, the system controller 3 selects the selected option (either the first setting time, the second setting time, the third setting time, or the fourth setting time). Start counting time. During timing, the system controller 3 generates a display signal for displaying the display time 95 and outputs the display signal to the video signal processing unit 23. Then, the display signal of the display time 95 is superimposed on the video signal by the video signal processing unit 23, and the display time 95 is synthesized with the projected video 98.

  According to this embodiment, the following effects occur.

(A) As the remaining amount of electricity stored in the storage battery 7 increases, the time measurement can be lengthened. The time keeping can be shortened as the remaining amount of electricity stored in the storage battery 7 decreases. Therefore, the variation of customization related to timekeeping can be changed according to the amount of remaining power in the storage battery 7.

(B) When the remaining operable time of the projection apparatus 1 is equal to or less than the first set time, the selection of the first set time is prohibited in the user setting relating to the time measurement time. Can be prevented. The same applies to the case where the remaining operable time of the projection apparatus 1 is equal to or shorter than the second set time, the third set time, or the fourth set time.

[Third Embodiment]
The same code | symbol is attached | subjected to what mutually respond | corresponds between 3rd Embodiment and 1st Embodiment.

  The projection apparatus 1 according to the third embodiment is configured similarly to the projection apparatus 1 according to the first embodiment (see FIG. 2). However, the program 5 stored in the program memory 4 according to the third embodiment is different from the program 5 stored in the program memory 4 according to the first embodiment. Further, the process executed by the system controller 3 according to the program 5 in the third embodiment is different from the process executed by the system controller 3 according to the program 5 in the first embodiment.

  In the first embodiment, the user setting relates to the output luminance of the projection apparatus main body 2 (particularly, the light source device 27), and whether or not the user setting option is acceptable is determined based on the remaining amount of power stored in the storage battery 7. On the other hand, in the third embodiment, the user setting relates to the time measurement (setting time), and whether or not the user setting option is acceptable is determined based on the remaining amount of power stored in the storage battery 7.

  FIG. 4 is a perspective view showing a usage state of the projection apparatus 1 according to the third embodiment.

  The output luminance of the projection device main body 2 (particularly the light source device 27) can be adjusted in two stages. That is, when the user 90 operates the operation unit 6 of the projection apparatus 1, the output luminance of the projection apparatus main body unit 2 can be selected between the high luminance setting and the low luminance setting. The brightness of the projection light 96 when the output brightness setting of the projection apparatus main body 2 is a high brightness setting is higher than the brightness of the projection light 96 when the output brightness setting of the projection apparatus main body 2 is a low brightness setting. high. The high luminance setting is a high power consumption setting, and the low luminance setting is a low power consumption setting. Note that the system controller 3 stores the contents of the user setting regardless of whether the user setting regarding the output luminance of the projection apparatus main body 2 is set to the high luminance setting or the low luminance setting.

  The user 90 performs projection using an image 98 projected by the projection apparatus 1. In the video 98, a display time 95 during counting is displayed. The display time 95 is displayed by the projection apparatus 1. That is, the display time 95 is combined with the video 98 by superimposing a signal for displaying the display time 95 on the video signal input to the projection apparatus 1. A timekeeping function is mounted on the projection apparatus 1, and a display time 95 represents the time counted by the projection apparatus 1. The numerical value of the display time 95 changes with time. The time is counted up or counted down. Therefore, the user 90 can make a lecture while recognizing the time from the start of the lecture and the remaining time of the lecture by visually confirming the display time 95.

  The user can increase or decrease the time keeping time (set time) stepwise by operating the operation unit 6 of the projection apparatus 1 before the start of time keeping, and there are a plurality of user setting options relating to the time keeping time. Specifically, the timekeeping time can be increased or decreased in four stages, and user setting options for the timekeeping time include a first setting time, a second setting time, a third setting time, and a fourth setting time. These timekeeping times are the same as those in the second embodiment, and a description thereof will be omitted.

When the output luminance setting of the projection apparatus main body 2 is the low luminance setting, whether or not the user setting option regarding the time measurement is permitted is determined in the same manner as in the second embodiment.
That is, if the remaining amount stored in the storage battery 7 exceeds the first threshold value for low luminance setting, the selection of the first setting time, the second setting time, the third setting time, and the fourth setting time in the user setting related to the clocking time is performed. Allowed.
Further, if the remaining amount stored in the storage battery 7 exceeds the first threshold value for low luminance setting and exceeds the second threshold value for low luminance setting (where the first threshold value for low luminance setting> the second threshold value for low luminance setting), In the user setting relating to the time measurement time, selection of the second setting time, the third setting time, and the fourth setting time is permitted, but the selection of the first setting time is prohibited.
Further, if the remaining amount stored in the storage battery 7 exceeds the second threshold value for low brightness setting and exceeds the third threshold value for low brightness setting (however, the second threshold value for low brightness setting> the third threshold value for low brightness setting) In the user setting relating to the time measurement time, selection of the third setting time and the fourth setting time is permitted, but selection of the first setting time and the second setting time is prohibited.
Further, if the remaining amount stored in the storage battery 7 exceeds the third threshold for low luminance setting and exceeds the fourth threshold for low luminance setting (however, the third threshold for low luminance setting> the fourth threshold for low luminance setting), Although the selection of the fourth setting time is permitted in the user setting relating to the time measurement time, the selection of the first setting time, the second setting time, and the third setting time is prohibited.
If the remaining amount stored in the storage battery 7 is equal to or lower than the low-brightness fourth threshold, selection of the first set time, the second set time, the third set time, and the fourth set time is prohibited in the user setting relating to the time measurement time. .

  When the output luminance setting of the projection apparatus main body 2 is selected as the high luminance setting, whether or not the user setting options relating to the timekeeping time are allowed is determined as follows (see Table 3 below). ).

(1) Permission of selection of first set time If the remaining amount stored in the storage battery 7 exceeds the first threshold for high luminance setting (first threshold for high luminance setting> first threshold for low luminance setting), the time is counted. Selection of the first set time is permitted in the user settings regarding time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the first threshold for setting high luminance and exceeds the first threshold for setting low luminance, the selection of the first setting time is permitted under certain conditions in the user setting relating to the timekeeping time. The condition is that the output luminance setting of the projection apparatus main body 2 is changed from the high luminance setting to the low luminance setting (the same applies to the following conditions (2) to (4)).
If the remaining amount stored in the storage battery 7 is equal to or lower than the first threshold for setting low luminance, selection of the first set time is prohibited in the user setting relating to the time measurement time.
Here, the first threshold for setting high brightness is a high threshold, and the first threshold for setting low brightness is a low threshold.

(2) Regarding Allowance of Selection of Second Setting Time The remaining amount stored in the storage battery 7 is the second threshold value for high luminance setting (second threshold value for high luminance setting> second threshold value for low luminance setting, the second threshold value for high luminance setting) If 2 threshold value <first threshold value for high brightness setting) is exceeded, selection of the second setting time is permitted in the user setting relating to the time measurement time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the second threshold value for high luminance setting and exceeds the second threshold value for low luminance setting, the selection of the second setting time is permitted under certain conditions in the user setting relating to the time measurement time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the second threshold value for low luminance setting, selection of the second set time is prohibited in the user setting relating to the time measurement time.
Here, the second threshold for setting high luminance is a high threshold, and the second threshold for setting low luminance is a low threshold.

(3) Acceptance of selection of the third set time The remaining amount stored in the storage battery 7 is a third threshold for setting high brightness (third threshold for setting high brightness> third threshold for setting low brightness, and the third threshold for setting high brightness). If 3 threshold value <second threshold value for high brightness setting) is exceeded, selection of the third setting time is permitted in the user setting relating to the time measurement time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the third threshold value for high luminance setting and exceeds the third threshold value for low luminance setting, the selection of the third setting time is permitted under certain conditions in the user setting relating to the timekeeping time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the third threshold value for low brightness setting, selection of the third set time is prohibited in the user setting relating to the time measurement time.
Here, the third threshold for setting high luminance is a high threshold, and the third threshold for setting low luminance is a low threshold.

(4) Regarding whether to permit selection of the fourth set time The remaining amount stored in the storage battery 7 is a fourth threshold for setting high brightness (fourth threshold for setting high brightness> fourth threshold for setting low brightness, and the fourth threshold for setting high brightness). If 4 thresholds <third threshold for high brightness setting), the selection of the fourth set time is permitted in the user setting relating to the time measurement time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the fourth threshold value for high luminance setting and exceeds the fourth threshold value for low luminance setting, the selection of the fourth setting time is permitted under certain conditions in the user setting related to the time measurement time.
If the remaining amount stored in the storage battery 7 is equal to or lower than the fourth threshold value for low luminance setting, selection of the fourth setting time is prohibited in the user setting relating to the time measurement time.
Here, the fourth threshold for setting high brightness is a high threshold, and the fourth threshold for setting low brightness is a low threshold.

Since the remaining amount stored in the storage battery 7 can be converted into the remaining high luminance setting time and the remaining low luminance setting time, the remaining amount of storage corresponds to the remaining high luminance setting time and the remaining low luminance setting time. The high luminance setting remaining time is a time during which the projection device 1 can operate with the remaining amount of storage of the storage battery 7 when the luminance setting of the projection device main body 2 (particularly, the light source device 27) is the high luminance setting. . The low luminance setting remaining time is a time during which the projection device 1 can operate with the remaining amount of storage of the storage battery 7 when the luminance setting of the projection device main body 2 (particularly, the light source device 27) is the low luminance setting. . If the remaining amount of electricity converted from the remaining high luminance setting time and the remaining amount of electricity converted from the remaining low luminance setting time are equal to each other, the remaining high luminance setting time is shorter than the remaining low luminance setting time.
Since the charge control unit 8 detects the remaining amount stored in the storage battery 7, the charge control unit 8 converts the detected remaining amount into a high luminance setting remaining time and a low luminance setting remaining time in which the projection apparatus 1 can operate. Part (converting means).

  Here, when the first threshold value for high luminance setting is converted into the remaining high luminance setting time during which the projection apparatus 1 can operate with the remaining power amount of the first threshold value for high luminance setting, the converted value is equal to the first set time. That is, the fact that the remaining amount stored in the storage battery 7 exceeds the first threshold value for high brightness setting corresponds to the remaining high brightness setting remaining time for which the projection apparatus 1 can operate exceeds the first set time. That the stored remaining amount is equal to or lower than the first threshold for setting high luminance corresponds to the remaining high luminance setting remaining time during which the projection apparatus 1 can operate being equal to or shorter than the first set time. Similarly, when the second threshold value for high luminance setting is converted into the remaining high luminance setting time, the converted value is equal to the second setting time. When the high-luminance third threshold value is converted into the high-luminance setting remaining time, the converted value is equal to the third setting time. When the fourth threshold value for high luminance setting is converted into the remaining high luminance setting time, the converted value is equal to the fourth setting time.

  Further, when the low-luminance setting first threshold value is converted into the low-luminance setting remaining time during which the projection apparatus 1 can operate with the remaining power storage amount of the low-luminance setting first threshold value, the converted value is equal to the first set time. That is, the fact that the remaining amount stored in the storage battery 7 exceeds the first threshold value for low brightness setting corresponds to the remaining low brightness setting remaining time for which the projection apparatus 1 is operable exceeds the first set time. 7 is equal to or less than the first threshold value for low brightness setting, this corresponds to the remaining low brightness setting time in which the projection apparatus 1 can operate being equal to or less than the first set time. Similarly, when the second threshold value for low luminance setting is converted into the remaining low luminance setting time, the converted value is equal to the second setting time. When the third threshold value for low luminance setting is converted into the low luminance setting remaining time, the converted value is equal to the third setting time. When the fourth threshold value for low luminance setting is converted into the low luminance remaining time, the converted value is equal to the fourth setting time.

1st threshold for high brightness setting, 2nd threshold for setting high brightness, 3rd threshold for setting high brightness, 4th threshold for setting high brightness, 1st threshold for setting low brightness, 2nd threshold for setting low brightness, low brightness The following table summarizes the relationship between the third threshold for setting, the fourth threshold for setting low luminance, the first setting time, the second setting time, the third setting time, and the fourth setting time.

  As described above, when the remaining operable time of the projection apparatus 1 in which the brightness of the projection light 96 is set to high brightness exceeds the first set time, or the projection in which the brightness of the projection light 96 is set to low brightness When the remaining time in which the device 1 can operate exceeds the first set time (when the remaining amount stored in the storage battery 7 exceeds the first threshold value for high brightness setting, or the remaining amount stored in the storage battery 7 has low brightness When exceeding the first threshold for setting), selection of the first set time is permitted in the user setting relating to the time measurement time. Therefore, it is possible to prevent the projection apparatus 1 from being out of charge before the timing of the first set time is completed. The same applies to the case where selection of the second set time, the third set time, or the fourth set time is permitted.

  When increasing / decreasing the time keeping time (set time), the user setting display area 93 as shown in FIG. In the user setting display area 93, a plurality of user setting options relating to time keeping are displayed. Among the options, the currently selected option and the unselected option are identified and displayed. When the user 90 operates the operation unit 6 while looking at the user setting display area 93, the time count can be increased or decreased.

  In addition, of the options displayed in the user setting display area 93, the options that are permitted to be selected, the options that are permitted to be selected under conditions, and the options that are prohibited from being selected are identified and displayed. For example, a selection is permitted with a circle, a condition with a selection permitted is marked with a triangle, and a selection is prohibited with a cross. In addition, characters representing options for which selection is prohibited are displayed in black, and characters representing options for which selection is prohibited are displayed in gray or translucent.

  In addition, when the user 90 selects the timer start icon in the user setting display area 93 by operating the operation unit 6, timing of the selected option (any one of the first to fourth setting times) is started. . On the other hand, when the user 90 selects the timer reset icon in the user setting display area 93 by operating the operation unit 6 during timing, the timing is reset. In the user setting display area 93, options related to the display position of the display time 95 are displayed. When the user 90 selects any option by operating the operation unit 6, the display time is displayed at the position of the selected option. 95 is displayed.

  Subsequently, processing executed by the system controller 3 based on the program 5 will be described. FIG. 8 is a flowchart of a main routine of determination processing executed by the system controller 3.

  As shown in FIG. 8, the system controller 3 determines the presence / absence of charge based on the charge presence / absence signal input from the charge control unit 8 (step S201). At this time, when power is supplied from the power supply device 9 to the charging control unit 8 (step S201: YES), the system controller 3 permits selection of the first to fourth set times, and the first to first settings. The fact that selection of the set time of 4 has been permitted is stored (step S202). Thereafter, the processing of the system controller 3 returns to step S201.

  On the other hand, when power is not supplied from the power supply device 9 to the charging control unit 8 (step S201: NO), the system controller 3 has a low user setting regarding the luminance of the projection device main body 2 (particularly the light source device 27). It is determined whether the luminance setting or the high luminance setting is set (step S203). This determination is made based on the contents stored in the system controller 3 or based on a dimming signal output from the system controller 3 to the light source control unit 26.

  When the luminance setting of the projection device main body 2 (particularly the light source device 27) is the low luminance setting (step S203: YES), the permission determination process (see S100 in FIG. 6) in the second embodiment is performed by the system controller 3. (Step S204). In this case, in the description of the permission / refusal decision processing with reference to FIG. 6 in the second embodiment, “the first threshold value” is “the first threshold value for low luminance setting” and “the second threshold value” is “ “Low luminance setting second threshold” and “third threshold” are read as “low luminance setting third threshold”, and “fourth threshold” is read as “low luminance setting fourth threshold”. . When the permission / rejection determination process shown in FIG. 6 is completed, the process of the system controller 3 returns to step S201.

  When the luminance setting of the projection apparatus main body 2 (particularly the light source device 27) is the high luminance setting (step S203: NO), the permission / refusal determination process S200 shown in FIG. When the permission / rejection determination process shown in FIG. 6 is completed, the process of the system controller 3 returns to step S201.

  Next, the permission / refusal determination process will be described with reference to the flowchart shown in FIG. As shown in FIG. 8, the system controller 3 selects user setting options (first set time, second set time, third set time, and time setting time) based on the remaining power storage amount detected by the charge control unit 8. Whether to select the fourth set time is determined (see Step S201A to Step S204A, Step S201B to Step S204B, Step S201C to Step S204C, Step S201D to Step S204D).

  With reference to FIG. 8, the process for determining whether or not to allow selection of the first set time as an option will be described. When determining whether to permit selection of the first setting time, the first threshold for setting high luminance and the first threshold for setting low luminance are used. That is, the system controller 3 compares the remaining power amount detected by the charge control unit 8 with the first threshold for setting high luminance and the first threshold for setting low luminance (steps S201A and S202A).

  As a result of the comparison, when the system controller 3 determines that the remaining amount of power storage exceeds the first threshold value for high brightness setting (step S201A: YES), the system controller 3 permits selection of the first set time (step S203A). ). Then, the system controller 3 stores that the selection of the first set time is permitted. Thereafter, the process proceeds to a determination process of whether to permit the selection of the second set time.

  As a result of the comparison, when the system controller 3 determines that the remaining power storage amount is equal to or lower than the first threshold value for high luminance setting and exceeds the first threshold value for low luminance setting (step S201A: NO, step S202A: YES), the system controller 3 permits the selection of the first set time with a condition (step S204A). Then, the system controller 3 stores that the selection of the first set time has been permitted under certain conditions. Thereafter, the process proceeds to a determination process of whether to permit the selection of the second set time.

  As a result of the comparison, if the system controller 3 determines that the remaining amount of power storage is equal to or lower than the first threshold value for low luminance setting (step S202A: NO), the system controller 3 prohibits selection of the first set time (step S205A). Then, the system controller 3 stores that the selection of the first set time is prohibited. Thereafter, the process proceeds to a determination process of whether to permit the selection of the second set time.

  Then, as shown in FIG. 8, whether or not selection of the second set time is permitted is determined, then whether or not the second set time is selected is determined, and then whether or not the third set time is selected is determined. Next, a determination is made as to whether or not the fourth set time is selected. When determining whether to permit selection of the second setting time, the third setting time, and the fourth setting time, the second threshold for setting high luminance, the second threshold for setting low luminance, the third threshold for setting high luminance, and the low luminance, respectively. A third threshold for setting, a fourth threshold for setting high brightness, and a fourth threshold for setting low brightness are used. The remaining power storage detected by the charge controller 8 by the system controller 3 is a second threshold for setting high brightness, a second threshold for setting low brightness, a third threshold for setting high brightness, a third threshold for setting low brightness, and a high brightness. The system controller 3 determines whether to permit the selection of the second set time, the third set time, and the fourth set time by comparing with the fourth threshold for setting and the fourth threshold for setting low brightness. This is the same as the process for determining whether or not to allow selection of the first set time by comparing the remaining power storage detected in step 1 with the first threshold for setting high brightness and the first threshold for setting low brightness. Step S201B to Step S205B, Step S201C to Step S205C, and S201D to Step S205D correspond to Step S201A to Step S205A, respectively.

Regardless of whether or not power is supplied from the power supply device 9 to the charging control unit 8, whether the luminance setting of the projection apparatus main body 2 (particularly the light source device 27) is the low luminance setting or the high luminance setting. When the user 90 inputs a user setting mode command by operating the operation unit 6, the system controller 3 executes a user setting process. The user setting process is performed after the process shown in FIG. 8 is performed once or more. However, since the process shown in FIG. 8 is repeatedly performed, the user setting process may be performed in parallel with the permission determination process (steps S100 and S200). Note that user setting processing may be performed following steps S202, S204, 203D to S205D of FIG.
The user setting process is a process for selecting one of user setting options (a first setting time, a second setting time, a third setting time, and a fourth setting time) for the time measurement. The user setting process will be specifically described below.

  First, the system controller 3 generates a display signal for the user setting display area 93 and outputs the display signal to the video signal processing unit 23. Accordingly, the display signal of the user setting display area 93 is superimposed on the video signal by the video signal processing unit 23, and the user setting display area 93 is combined with the projected video 98.

  At this time, the system controller 3 stores the storage results (steps 102A, S103A, S102B, S103B, S102C, S103C, S102D, S103D, S202, S203A to S205A) by the permission determination processing (S100, S200) shown in FIGS. Based on S203B to S205B, S203C to S205C, and S203D to S205D), display modes of a plurality of options (first setting time, second setting time, third setting time, and fourth setting time) are determined and displayed. The display signal of the user setting display area 93 according to the above is generated. Specifically, the system controller 3 generates a display signal that makes it possible to distinguish between a selection permitted, a selection permitted under certain conditions, and a selection prohibited selection. The display signal is output to the video signal processing unit 23. That is, notification is given so that an option forbidden by the permission determination unit, an option for which the selection is permitted, and an option for which the condition is permitted to be selected can be identified.

Thereafter, the user 90 operates the operation unit 6 to select any one option. That is, when the user 90 operates the operation unit 6, a signal corresponding to the operation content is output to the system controller 3, and the system controller 3 selects any one option based on the signal.
At this time, the system controller 3 does not accept selection of an option that is prohibited by the result of the permission / refusal determination process (S100) shown in FIG. 6 or the permission / refusal determination process (S200) shown in FIG.
Further, the system controller 3 accepts selection of the permitted option based on the result of the permission / refusal determination process (S100) shown in FIG. 6 or the permission / refusal determination process (S200) shown in FIG.
In addition, the system controller 3 accepts selection of a conditionally permitted option based on the result of the permission / rejection determination process (S100) shown in FIG. 6 or the permission / rejection determination process (S200) shown in FIG. In this case, the system controller 3 outputs a dimming signal indicating low luminance to the light source control unit 26, and the light source control unit 26 causes the light source device 27 to emit light with low luminance.

  Then, when the user 90 selects the timer start icon by operating the operation unit 6, the system controller 3 selects the selected option (either the first setting time, the second setting time, the third setting time, or the fourth setting time). Start counting time. During timing, the system controller 3 generates a display signal for displaying the display time 95 and outputs the display signal to the video signal processing unit 23. Then, the display signal of the display time 95 is superimposed on the video signal by the video signal processing unit 23, and the display time 95 is synthesized with the projected video 98.

  According to this embodiment, the following effects occur.

(A) As the remaining amount of electricity stored in the storage battery 7 increases, the time measurement can be lengthened. The time keeping can be shortened as the remaining amount of electricity stored in the storage battery 7 decreases. The number of options that can be selected when the brightness setting of the projection apparatus body 2 is a low brightness setting is the number of options that can be selected when the brightness setting of the projection apparatus body 2 is a high brightness setting. Tend to be more. Therefore, the variation of customization related to timekeeping can be changed according to the amount of remaining power in the storage battery 7.

(B) When the brightness setting of the projection apparatus main body 2 is the low brightness setting, if the remaining low brightness setting remaining time during which the projection apparatus 1 can operate is equal to or less than the first set time, the first set time in the user setting relating to the time measurement time Therefore, it is possible to prevent the projection apparatus 1 from being out of charge in the middle of timing. The same applies when the remaining low-luminance setting remaining time during which the projection apparatus 1 can operate is equal to or shorter than the second setting time, the third setting time, or the fourth setting time.

(C) When the brightness setting of the projection apparatus main body 2 is the high brightness setting, if the remaining high brightness setting remaining time during which the projection apparatus 1 can operate is equal to or less than the first set time, the first set time in the user setting relating to the time measurement time Is permitted or prohibited under certain conditions, so that it is possible to prevent the projector 1 from being out of charge in the middle of timing. The same applies when the remaining high-luminance setting remaining time during which the projection apparatus 1 can operate is equal to or shorter than the second setting time, the third setting time, or the fourth setting time.

(D) When the brightness setting of the projection apparatus main body 2 is a high brightness setting, even if the remaining high brightness setting time in which the projection apparatus 1 can operate is less than or equal to the first set time, If the remaining luminance setting time exceeds the first setting time, the selection of the first setting time is permitted under certain conditions in the user setting related to the time measurement time. For this reason, even if the first set time cannot be selected in principle as in (c) above, if the user wants to measure the first set time, the first set time can be measured. Even when the first set time is measured, the luminance setting of the projection apparatus main body 2 is changed from the high luminance setting to the low luminance setting. Therefore, it is possible to prevent the charging of the projection apparatus 1 from occurring during the time measurement. The same applies when the remaining high-luminance setting remaining time during which the projection apparatus 1 can operate is equal to or shorter than the second setting time, the third setting time, or the fourth setting time.

[Modification]
The functions of the first to third embodiments described above may be incorporated in the projection apparatus 1 and the system controller 3 may perform the processes of the first to third embodiments. For example, when the first mode is set by the mode setting, the controller 3 executes the process of the first embodiment, and when the second mode is set by the mode setting, the controller 3 is the second embodiment. When the third mode is set by the mode setting, the controller 3 executes the process of the third embodiment. In the mode setting, the user 90 can select one of the first mode, the second mode, and the third mode by operating the operation unit 6 of the projection apparatus 1.

  In the first to third embodiments described above, the system controller 3 first determines whether or not the projection apparatus 1 is charged, and when charging is in progress, it can select all user setting options. Therefore, it is possible to prevent the selection of the user setting from being disabled when the projection apparatus 1 is being moved by the external power supply during charging and the storage battery has a small remaining power.
