Description

  The present invention relates to a parameter setting device, a parameter setting program, and a parameter setting method for setting various parameters.

  Conventionally, for example, in a digital camera, an auto mode and a manual mode can be selectively set. In the manual mode, a user can arbitrarily set various parameter values. Conventional parameter value setting methods in this manual mode can be broadly classified into direct methods and indirect methods.

  In the direct method, a plurality of types of parameters are displayed on the display unit, and when any parameter is selected by operating the cursor key and the decision key, a plurality of values that can be set in the parameter are displayed. If any one of these plural types of values is similarly selected by operating the cursor key and the enter key, the selected value is stored as the parameter value of the parameter.

In the indirect method, a plurality of options consisting of questionnaire-like questions are displayed without displaying the types of parameters that are technical matters. When one of these options is selected, multiple options are displayed, including detailed questions below it. When one of these options is selected, more detailed questions below are displayed. When the selection of the question item of the final layer is completed, the parameter value is determined and stored (see, for example, Patent Document 1).

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a rear view of a digital camera common to the respective embodiments of the present invention, and is also a diagram showing processing contents of step S502 described later in the present embodiment. A shutter button 11 is provided on the top surface of the digital camera 1 and a liquid crystal monitor 16 is provided on the back surface. On the side of the liquid crystal monitor 16, rectangular first to fourth switches 2 to 5 are provided, and an upper cursor switch 6, a lower cursor switch 7, a left cursor switch 8, and a right cursor switch 9 are provided. The ring-shaped switch which has integrally, and the determination switch 10 arrange | positioned in the center part of this ring-shaped switch are provided.

  FIG. 2 is a block configuration diagram showing an outline of the electrical configuration of the digital camera 1. The digital camera 1 is mainly configured by an MPU 19 having an image processing function such as converting an image captured by a CCD 17 constituting an imaging unit together with a lens 12 and the like into a JPEG format. On the light receiving surface of the CCD 17, an optical image of the subject is formed through the lens 12, the focus lens 20, and the diaphragm 21. The focus lens 20 is held by a drive mechanism 22 composed of an AF motor or the like, and moves forward and backward on the optical axis when a drive signal output from the AF driver 23 is supplied to the drive mechanism 22 by a control signal from the MPU 19. Perform focusing operation. The diaphragm 21 is driven by a drive signal generated by the diaphragm drive unit 24 based on a control signal from the MPU 19, and adjusts the light quantity of the subject image incident on the CCD 17.

  The MPU 19 is connected with a TG (Timing Generator) 25 that generates a timing signal, and a V driver 26 (vertical driver) drives the CCD 17 based on the timing signal generated by the TG 25. An analog imaging signal corresponding to the luminance of the image is output and sent to the unit circuit 18. The unit circuit 18 includes a CDS that holds an imaging signal output from the CCD 17, a gain adjustment amplifier (AGC) that is an analog amplifier that is supplied with the imaging signal from the CDS, and an imaging signal that has been amplified and adjusted by the gain adjustment amplifier. It comprises an A / D converter (AD) that converts it into image data, and the output signal of the CCD 17 is sampled with the black level matched here and sent to the MPU 19 as a digital signal. The sent digital signal (imaging signal) is temporarily stored in the DRAM 27, and after various image processing is performed by the MPU 19, it is finally stored in the flash memory (FLASH) 28 as a compressed video signal. . The stored video signal is read by the MPU 19 as necessary, and is generated into a digital video signal or an analog video signal through processing such as expansion processing, addition of a luminance signal and a color signal.

  Further, the MPU 19 is connected to the MROM 29, the power supply circuit 30, the operation key unit 31 including the various switches 2 to 10 shown in FIG. 1, the liquid crystal monitor 16, the photometric sensor 14, and the flash device 15. The MROM 29 is a program ROM in which an operation program of the MPU 19 shown in a flowchart described later is recorded.

  The MROM 29 stores a plurality of parameter values that can be manually set for each of the shutter speed, aperture, photometry, ISO sensitivity, and white balance, and an aperture corresponding to an appropriate exposure value (EV) at the time of shooting. Also stored is program AE data or the like that constitutes a program diagram showing a combination of the value (F) and the shutter speed.

  The MPU 19 controls each part of the digital camera 1 by operating the built-in RAM as a working memory according to the operation program, and according to the program diagram, the charge accumulation time of the CCD 17, the degree of opening of the diaphragm 21, The gain of the gain adjustment amplifier (AGC) of the unit circuit 18 is set. The charge accumulation time set by the MPU 19 is supplied as a shutter pulse to the V driver 26 via the TG 25, and the charge accumulation time, that is, the exposure time is controlled by the V driver 26 driving the CCD 17 according to this. That is, the CCD 17 functions as an electronic shutter. The operation program stored in the MROM 29 includes a program related to autofocus control. Based on the program, the MPU 19 drives the focus lens 20 to perform focusing (autofocus).

  The liquid crystal monitor 16 displays sequentially captured images as through images in the shooting mode, and displays images based on analog video signals generated from the image data recorded in the flash memory 28 in the playback mode. The flash device 15 is driven as necessary to operate the video capture key (when shooting) and emit auxiliary light.

  The program data and the like stored in the MROM 29 described above can be stored on another recording medium such as an IC card that is separately provided or detachably mountable as long as the recorded contents can be retained. The program data may be recorded, and the program data may be supplied from another device such as a personal computer.

  In the present embodiment having the above configuration, when the power switch is turned on, the MPU 19 executes the processing shown in the flowchart of FIG. 3 according to the program stored in the MROM 29. That is, the MPU 19 first performs an initialization process to erase unnecessary data in the built-in RAM or DRAM 27 (step S1). Next, it is determined whether or not a shooting mode is set (step S2). If another mode other than the shooting mode such as a playback mode is set, the process proceeds to the other mode processing (step S2). S3).

  If the shooting mode is set, it is determined whether the auto mode or the manual mode is set (step S4). If the manual mode is set, after performing a manual setting process described later (step S5), the process proceeds to step S6. If the auto mode is set, the process directly proceeds to step S6 to determine whether or not the shutter button 11 has been pressed. If the shutter button 11 is not pressed, the process proceeds to step S11 without performing the processes of steps S7 to S10.

  If the shutter button 11 is pressed, AF (autofocus) processing is executed (step S7). That is, the MPU 19 controls the AF driver 23 based on a program related to autofocus control stored in the MROM 29, and drives and drives the focus lens 20 by the drive mechanism 22 to perform focusing (focusing).

  Further, it is determined whether the setting mode is the auto mode or the manual mode (step S8). When the setting mode is the auto mode, various parameter values are automatically set according to the measurement value of the photometric sensor 14, the program AE data, etc. (step S9), and then the process proceeds to step S10. When the setting mode is the manual mode, the process proceeds to step S10 without executing the process of step S9. However, in the manual mode, various parameter values are manually set in step S5 as will be described later.

  Therefore, in step S10, when the auto mode is set, the imaging / recording process is executed according to the parameter setting value automatically set in step S9, and when the manual mode is set, In step S5, an image capturing / recording process is executed according to the parameter setting value manually set. Then, by executing this imaging / recording process, the optical image of the subject formed on the light receiving surface of the CCD 17 is stored in the flash memory 28 as a finally compressed video signal. Subsequently, other processing is executed (step S11), it is determined whether the power is turned off (step S12), and the processing from step S2 is repeated until the power is turned off.

  FIG. 4 is a subroutine showing details of the manual setting process (step S5). In the manual mode, it is determined whether or not the shutter speed has already been determined (step S501). If the shutter speed has not yet been determined (if not stored in the RAM built in the MPU 19), a shutter speed setting screen display is executed (step S502).

  In this shutter speed setting screen display, “1/1000”, “1/500”,..., “5”, which are parameter values that can be manually set in the shutter speeds in the switches 2 to 10 (see FIG. 1), Assign “10”. As shown in FIG. 1, the liquid crystal monitor 16 provided on the left side of the switches 2 to 10 has the same shape as the switches 2 to 10 and the switch images 2 'to 2 having the same positional relationship. 10 'is displayed. Further, parameter values assigned to the switches 2 to 10 corresponding to or near the switch images 2 'to 10' are displayed. Thus, the parameter value “1/1000” is in the vicinity of the switch image 2 ′, the parameter value “1/500” is in the vicinity of the switch image 3 ′, and the parameter value is in the vicinity of the switch image 9 ′. “5” and the parameter value “10” are respectively displayed in the switch image 10 ′.

  Next, it is determined whether or not an operation has been performed on any of the switches 2 to 10 (step S503). If any of the switches 2 to 10 is operated, the shutter speed setting process is performed, and the parameter value assigned to the operated switch is stored in the RAM built in the MPU 19 as a manually set shutter speed. (Step S504).

  If the shutter speed has already been determined, it is determined whether or not the aperture has been determined (step S505). If the aperture has not yet been determined (if it is not stored in the RAM built in the MPU 19), the aperture setting screen display is executed (step S506).

  In this aperture setting screen display, a parameter value that can be manually set in the aperture is assigned to the switches 2 to 10 (see FIG. 1), and a liquid crystal monitor provided on the left side of the switches 2 to 10 as described above. 16 displays switch images 2 ′ to 10 ′ having the same shape as the switches 2 to 10 and having the same positional relationship, and corresponding to the vicinity of or inside the switch images 2 ′ to 10 ′. The parameter values assigned to the switches 2 to 10 are displayed.

  Next, it is determined whether or not an operation has been performed on any of the switches 2 to 10 (step S507). If any of the switches 2 to 10 has been operated, aperture setting processing is performed, and the parameter value assigned to the operated switch is stored in the RAM built in the MPU 19 as a manually set aperture (step). S508).

  If the aperture has already been determined, it is determined whether or not the photometric method has been determined (step S509). When the metering method has not been determined yet (when not stored in the RAM built in the MPU 19), the metering method setting screen is displayed (step S510).

  In this photometry method setting screen display, a manually set photometry method is assigned to the switches 2 to 10 (see FIG. 1), and the liquid crystal monitor 16 provided on the left side of the switches 2 to 10 is the same as described above. In addition, switch images 2 'to 10' having the same shape as the switches 2 to 10 and having the same positional relationship are displayed, and the switches corresponding to the vicinity of or inside the switch images 2 'to 10' are displayed. The metering method assigned to 2 to 10 is displayed.

  Next, it is determined whether or not an operation has been performed on any of the switches 2 to 10 (step S511). If any of the switches 2 to 10 is operated, the photometric method setting process is performed, and the photometric method assigned to the operated switch is stored in the RAM built in the MPU 19 as a manually set photometric method. (Step S512).

  If the number of types of metering methods that can be manually set is less than switches 2 to 10, for example, if there are only three types, metering methods are assigned only to switches 2, 3, and 4, and these metering methods are Only the switch images 2 ', 3', 4 'corresponding to the assigned switches 2, 3, 4 may be displayed.

  If the photometric method has already been determined, it is determined whether the ISO sensitivity has been determined (step S513). If the ISO sensitivity has not yet been determined (if not stored in the RAM built in the MPU 19), the ISO sensitivity setting screen display is executed (step S514).

  In this ISO sensitivity setting screen display, a parameter value that can be manually set in the ISO sensitivity is assigned to the switches 2 to 10 (see FIG. 1), and is provided on the left side of the switches 2 to 10 as described above. On the liquid crystal monitor 16, switch images 2 'to 10' having the same shape as the switches 2 to 10 and having the same positional relationship are displayed and correspond to the vicinity or the inside of these switch images 2 'to 10'. The parameter values assigned to the switches 2 to 10 are displayed.

  Next, it is determined whether or not an operation has been performed on any of the switches 2 to 10 (step S515). If any of the switches 2 to 10 is operated, the ISO sensitivity setting process is performed, and the parameter value assigned to the operated switch is stored in the RAM built in the MPU 19 as the manually set ISO sensitivity. (Step S516).

  If the ISO sensitivity has already been determined, it is determined whether the white balance has been determined (step S517). When the white balance has not yet been determined (when not stored in the RAM built in the MPU 19), a white balance setting screen display is executed (step S518).

  In this white balance setting screen display, parameter values that can be manually set in white balance are assigned to the switches 2 to 10 (see FIG. 1), and are provided on the left side of the switches 2 to 10 as described above. On the liquid crystal monitor 16, switch images 2 'to 10' having the same shape as the switches 2 to 10 and having the same positional relationship are displayed and correspond to the vicinity or the inside of these switch images 2 'to 10'. The parameter values assigned to the switches 2 to 10 are displayed.

  Next, it is determined whether or not an operation has been performed on any of the switches 2 to 10 (step S519). If any of the switches 2 to 10 is operated, white balance setting processing is performed, and the parameter value assigned to the operated switch is stored in the RAM built in the MPU 19 as a manually set white balance. (Step S520).

  Accordingly, the parameter values and the like are displayed in correspondence with the switch images 2 'to 10' together with the switch images 2 'to 10' by the above processing, so that only the choices are displayed in characters in the hierarchical structure display. In this case, the display form is not difficult to view, and display can be performed in an easy-to-view display form.

  In addition, since the switch images 2 'to 10' have the same shape as the switches 2 to 10 and are displayed in the same positional relationship, the user can assign the assigned parameter value and the switch images 2 'to 10'. Can be easily grasped.

  Further, it is not necessary to perform a selection operation with a cursor key as in the prior art, and a complicated operation to determine a selection with a determination key, and a parameter value or the like can be easily set by a one-touch operation on the switches 2 to 10. it can. Therefore, even a beginner who is unfamiliar with manual setting in a digital camera can easily perform shooting with manual setting.

  When a switch operation is detected (steps S503, S507, S511, S515, S519 → YES), the parameter types that have not been determined (steps S501, S505, S509, S513, S517 → NO) are sequentially selected. Screen display (steps S502, S506, S510, S514, S518), it is possible to reliably perform manual setting for all types of parameters that can be manually set.

(Second Embodiment)
