Abstract

<P>PROBLEM TO BE SOLVED: To dissolve respective demerits of both a short-time pressing type controller and a long-time pressing type start controller. <P>SOLUTION: A power-off state is maintained (S101). When a power switch is pressed in that state, a timer is started, and a switch pressing time of a user to the power switch is measured (S103). It is decided whether the measured switch pressing time accords with a preceding pressing time in the off-state stored in a RAM in S110 or not (S104). When the switch pressing time of the power switch accords with the preceding pressing time in the off-state (S104; YES), power is turned on (S106). The timer is started when the power switch 3 is pressed in a power-on state (S108), and a pressing time measured by the timer is stored in the RAM when the user stops the pressing operation of the power switch (S110). <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a startup control device, a startup control program, and a startup method for an electronic device that activates a power source and other functions of various electronic devices.

2. Description of the Related Art Conventionally, various electronic devices are provided with a startup control device that operates when a function of the device is turned on, such as a startup circuit having a power button that is operated when the power is turned on (for example, , See Patent Document 1). There are so-called short-press type and long-press type in this start-up control device. In the short-press type start-up control device, only the operation button is operated instantaneously, and the corresponding function of the power supply etc. In a long-press type activation control device, a corresponding function such as a power source is turned on on condition that the operation button has been operated for a predetermined duration, for example, 1 second.
JP 2004-78080 A

  The short-press type activation control device has an advantage that a function corresponding to an instant can be turned on in a short operation time. On the other hand, if the device with this activation control device is a portable device, when it is carried in a pocket or bag, etc., and the carrying force is applied to the operation button, the function corresponding to unexpectedly turns on. Thus, there is a demerit that unnecessary start-up occurs. Further, even when the device having the activation control device is a stationary device, the function corresponding to when the operation button is inadvertently touched is turned on, resulting in unnecessary activation.

  On the other hand, in the long-press type start-up control device, the function corresponding to the condition that the operation button has been operated for a predetermined duration is turned on. There is no disadvantage that the corresponding function is turned on or that the corresponding function is turned on when the operation button is inadvertently touched. However, since the corresponding function is turned on after a predetermined duration after the user starts the button operation, there is a time lag from the operation to the activation. For this reason, due to the presence of this time lag, the user may not be able to use the function effectively. For example, when a digital camera is provided with a long-press type power activation control device, even if the user encounters a scene that the user thinks is a photo opportunity and operates the power button, the time lag will not occur until the power is turned on. Since it intervenes, there arises a disadvantage that a photo opportunity is lost due to a change in the scene in the meantime.

  An object of the present invention is to provide an activation control device, an activation control program, and an activation method of an electronic device that can eliminate both disadvantages of an activation control device of a short press type and a long press type.

  In order to solve the above-mentioned problem, the activation control device according to the first aspect of the present invention has an operation element, and the predetermined function of the device is provided on the condition that the operation element is operated with a predetermined duration. And a setting means for arbitrarily setting the duration time.

  Therefore, when the device is a portable device and is carried in a pocket or bag, or when the device is a stationary device, there is a possibility that the operator may be inadvertently touched. By setting a long duration, it is possible to eliminate the disadvantage (unnecessary short-press type) that unnecessary use occurs. In addition, when the function cannot be effectively used by the user due to a time lag from when the operation element is operated until the corresponding function is turned on, a short duration is set, thereby causing inconvenience due to the time lag ( Long press type demerit) can be eliminated.

  In the activation control device according to the second aspect of the present invention, an operation element that is operated when a predetermined function of the device is turned on and off, and an operation continuation when the operation element is operated when the apparatus is turned off. An acquisition means for acquiring time; a determination means for determining a required operation duration time at the time of ON based on the operation duration time acquired by the acquisition means; and the determination means when the operation element is operated at the ON time. And a control means for turning on the predetermined function of the device on the condition that the operation is performed with the required operation duration determined by the above.

  Therefore, according to the operation continuation time when the predetermined function of the device is turned off, it is possible to change the time required for the predetermined function to be turned on after the operation element is operated when the device is turned on. Therefore, by changing the operation continuation time when the user turns off the predetermined function of the device, the activation control device of the device can be changed to either the short press type or the long press type as needed. Therefore, by making the activation control device of various devices a short press type and a long press type according to the type of the device and the environment in which the device is placed, the disadvantages of both types can be eliminated at any time, An appropriate time lag can be set.

  In the activation control device according to the third aspect of the present invention, the determination unit determines the operation duration acquired by the acquisition unit as the required operation duration. Therefore, not only can the activation control device of various devices be either a short press type or a long press type by an easy operation that changes the operation duration when the predetermined function of the device is turned off. An appropriate time lag can be set.

  In the activation control device according to the fourth aspect of the invention, the determination unit determines a time different from the operation duration acquired by the acquisition unit as the required operation duration. Therefore, an appropriate time lag can be set according to the operation continuation time when the predetermined function of the device is turned off.

  Further, in the activation control device according to the invention of claim 5, the operation control device includes a plurality of the operation elements, and the acquisition unit acquires the operation continuation time when each operation element is operated at the off time. The determining means determines a required operation duration when each operation element is turned on based on each operation duration acquired by the acquisition means. Therefore, it is possible not only to set the activation control device of various devices for each of a plurality of functions of the device to either the short press type or the long press type, but also to set an appropriate time lag.

  In the activation control apparatus according to the invention described in claim 6, the function of the device is a power supply, and the operation element is a power button. Therefore, the time required from when the power button is operated when the power is turned on to when the power is turned on can be changed according to the operation continuation time when the power button is operated when the power is turned off. Therefore, by changing the operation continuation time when the user turns off the power, the device can be turned on either short-press type or long-press type, and an appropriate time lag is set when the power is turned on. You can also

  In the activation control device according to the invention described in claim 7, the first and second operating elements respectively operated when the first and second functions of the device are turned on, and the first and second Control means for turning on the corresponding first and second functions on condition that the second operation elements are operated with different predetermined durations. Therefore, the time lag until the corresponding function is turned on when the first operation element is operated is different from the time lag until the corresponding function is turned on when the second operation element is operated. It can be. Therefore, for example, when the function corresponding to the first operation element has a slight or unnecessary time lag, and the function corresponding to the second operation element requires a time lag, the setting of the time lag or an appropriate time lag is set according to each function. Can be set.

  In the activation control device according to the eighth aspect of the invention, the device is a digital camera, and the first operator is a record operated when a recording mode for capturing an image is turned on. The second operation element is a reproduction mode key operated when a reproduction mode for reproducing a recorded image is turned on, and the control means is configured such that the recording mode key is the reproduction mode. The recording mode is turned on on the condition that the recording mode key is operated in a shorter time than the key, and the playback mode is turned on on the condition that the playback mode key is operated in a time longer than the recording mode key. Therefore, when the recording mode key is operated, the recording mode is activated more quickly, so that loss of a photo opportunity can be prevented in advance. Therefore, when the playback mode key is operated, the playback mode is activated with a time lag, so that it is possible to prevent inconvenience that a playback image is seen by another person due to an inadvertent start of playback.

  The activation control program according to the invention of claim 9 has an operation element, and turns on a predetermined function of the device on condition that the operation element has been operated with a predetermined duration. A computer included in the electronic device is caused to function as setting means for arbitrarily setting the duration. Therefore, when the computer executes processing according to this program, the same effects as those of the first aspect of the invention can be obtained.

  In addition, in the activation control program according to the invention of claim 10, there is provided a computer included in an electronic device provided with an operator operated when a predetermined function of the device is turned on and off, and when the operator is turned off. An acquisition means for acquiring an operation duration time when operated, a determination means for determining a required operation duration time at an ON time based on the operation duration time acquired by the acquisition means, and the operation element operated at the ON time When it is done, it is made to function as a control means for turning on the predetermined function of the device on condition that the operation is performed with the required operation duration determined by the determination means. Therefore, when the computer executes processing according to this program, the same effects as those of the first aspect of the invention can be obtained.

  According to the eleventh aspect of the invention, there is provided an electronic device activation method for turning on a predetermined function of the device on condition that the operation device has an operation element and the operation element is operated with a predetermined duration. The duration time is arbitrarily set. Therefore, by performing the described setting, the same function and effect as those of the second aspect of the invention can be achieved.

If there is a possibility that the operator may be inadvertently touched in some cases, it is possible to eliminate the demerit (short depressing type demerit) that causes unnecessary activation by setting a long duration. . In addition, when the function cannot be effectively used by the user due to a time lag from when the operation element is operated until the corresponding function is turned on, a short duration is set, thereby causing inconvenience due to the time lag ( Long press type demerit) can be eliminated. Therefore, it is possible to eliminate both disadvantages of the short press type and long press type activation control devices. In addition, an appropriate time lag can be set according to the type of device, the environment in which the device is placed, or the corresponding function, whereby the corresponding function can be expressed in a timely manner.

  Further, according to the inventions according to claims 2, 10, and 12, the predetermined function is turned on after the operation element is operated at the time of turning on according to the operation duration when the predetermined function of the device is turned off.

Therefore, by making the activation control device of various devices a short press type and a long press type according to the type of the device and the environment in which the device is placed, the disadvantages of both types can be eliminated at any time, An appropriate time lag can be set.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)

  FIG. 1 is a rear perspective view of a digital camera 1 to which an embodiment of the present invention is applied. As shown in the figure, the digital camera 1 is provided with a power switch 3 and a shutter key 4 on the upper surface of the camera body 2, and an optical viewfinder 5 and a playback (PLAY) mode are set on the rear surface of the camera body 2. A playback mode key 61 that is operated when setting a recording mode, a recording mode key 62 that is operated when setting a recording (REC) mode, a liquid crystal monitor 7 that displays a recorded image and various types of information and functions as an electronic viewfinder, a menu A menu (MENU) key 8 for displaying a screen and an operation key 9 used for selecting and confirming a displayed menu item are disposed.

  FIG. 2 is a block diagram showing an outline of the electrical configuration of the digital camera 1. The digital camera 1 includes a CCD 11 that is an image sensor disposed behind the optical axis of an imaging lens 10 disposed on the front side (not shown) of the camera body 2. The CCD 11 is scan-driven by a timing generator (TG) 12 and a vertical driver 13 and outputs an image signal for one screen at a constant period.

  The output signal of the CCD 11 is appropriately adjusted for each RGB primary color component in an analog signal state, sampled and held by a sample hold circuit (S / H) 14, and converted into digital data by an A / D converter 15. It is sent to the color process circuit 16. The color process circuit 16 generates a digital luminance signal Y and color difference signals Cb and Cr by color process processing including image interpolation processing, and outputs it to a DMA (Direct Memory Access) DMA controller 17.

  The DMA controller 17 once writes the luminance signal Y and the color difference signals Cb and Cr into the buffer in the DMA controller 17 using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 16, and the DRAM interface (I / F) DMA transfer to DRAM 19 via 18. After the DMA transfer of the luminance and color difference signal data, that is, the image data to the DRAM 19, the control unit 20 reads the image data from the DRAM 19 via the DRAM interface 18 and writes the image data to the VRAM 22 via the VRAM controller 21.

  The digital video encoder 23 periodically reads out the image data from the VRAM 22 via the VRAM controller 21, generates a video signal based on these data, and outputs the video signal to the display unit 24. The display unit 24 is constituted by the liquid crystal monitor 7 and its drive circuit and the like, and performs display based on the video signal from the digital video encoder 23, thereby based on the image information captured from the VRAM controller 21 at that time. Display a through image.

  The key input unit 25 includes the power switch 3, the shutter key 4, the playback mode key 61, the recording mode key 62, and the like described above. When the shutter key 4 is operated in a state where a through image is displayed, the key input unit 25 is operated. Then, a trigger signal for starting imaging is generated.

  In the still image capturing mode in the recording mode, the control unit 20 stops the path from the CCD 11 to the DRAM 19 in response to the trigger signal, and the image data for one frame written in the DRAM 19 is transmitted via the DRAM interface 18. Read out and sent to the JPEG circuit 26. The JPEG circuit 26 compresses and encodes the sent image data, and the compressed image data is read out by the control unit 20 and recorded as a still image file in a flash memory 27 which is a nonvolatile memory.

  The image file recorded in the flash memory 27 is read into the JPEG circuit 26 in accordance with the selection operation by the operation key 9 or the like in the reproduction mode, and is decoded into image data there, and then to the VRAM 22 via the VRAM controller 21. Sent and displayed on the display unit 24.

  The power supply circuit 28 controls power supplied from the battery 29 to each unit. The control unit 20 is a microcomputer mainly composed of a CPU and its peripheral circuits, a RAM that is a working memory of the CPU, and a built-in clock having a calendar function. The control unit 20 includes a timer and is secured in the flash memory 27. It operates based on the program stored in the program area, and controls the operation of each part described above including the power supply circuit 28.

  In this Embodiment which concerns on the above structure, the control part 20 performs a process according to the flowchart shown in FIG. 3 based on the said program. That is, the power supply circuit 28 is controlled to maintain the power OFF state in which the power supply from the battery 29 to each unit is stopped (step S101). In this state, the power switch 3 is monitored and the power switch 3 is pushed. It is determined whether or not (step S102). If the power switch 3 is pressed, a timer is started to measure a switch pressing time that is a time during which the user continues to press the power switch 3 (step S103).

  Next, the measured switch pressing time is the OFF pressing time immediately before being stored in the RAM in step S110 to be described later, that is, when the user previously operated the power switch 3 to turn off the power. Then, it is determined whether or not the time for which the pressing operation of the power switch 3 is continued is coincident (step S104). If the switch pressing time does not yet coincide with the previous OFF pressing time, it is determined whether or not the pressing operation of the power switch 3 is being continued (step S105).

  At this time, if the user stops pressing the power switch 3 before the previous OFF pressing time, the determination in step S105 is NO, and the process goes to step S102 without performing the power ON process in step S106. Return. Therefore, when the user does not perform the pressing operation of the power switch 3 until the previous pressing time of OFF, the power is turned off and the operation of the power switch 3 is monitored without turning on the power. Return to.

  If the user continues to push the power switch 3, the loop of steps S104 → S105 → S104 is repeated. Then, when the switch pressing time of the power switch 3 coincides with the pressing time immediately before OFF (step S104; YES), the power ON process is executed and power is supplied to each part via the power circuit 28 (step S106). ). As a result, the still image file in the recording mode can be recorded in the flash memory 27 and the image file can be reproduced on the display unit 24 in the reproduction mode.

  Further, the control unit 20 monitors the power switch 3 in a power-on state where power is supplied to each unit, and determines whether or not the power switch 3 has been pressed (step S107). If the power switch 3 is pressed, a timer is started and measurement of a switch pressing time, which is a time during which the user continues to press the power switch 3, is started (step S108). Subsequently, it is determined whether or not the pressing operation of the power switch 3 is continued (step S109). While the user continues the pressing operation of the power switch 3, the timer started in step S108 is incremented. Let it continue. When the user stops pressing the power switch 3, the determination in step S109 is NO, and the process proceeds to step S110 where the pressing time measured by the timer is stored in the RAM.

  The pressing time when the power is turned off stored in the RAM in step S110 is used as the pressing time when the power is turned off immediately before in step S104. Therefore, in this embodiment, when the power is turned on, the power is turned on when the power switch 3 is pushed and operated for a time that coincides with the pressing time immediately before the power is turned off.

  However, the present invention is not limited to this, and the time lag may be determined based on the immediately preceding OFF pressing time, and the determined time lag may be stored as the pressing time in step S110. In step S110, as in this embodiment, the last OFF time is stored, and when the determination in step S104 is made, a time lag is determined based on the last OFF time, and the power is turned on. It may be determined whether the switch pressing time at the time coincides with the determined time lag.

  (Second Embodiment)

  FIG. 4 is a diagram showing a table 201 stored in the ROM of the control unit 20 in the second embodiment of the present invention. In this table 201, the stored pressing time stored in the RAM in step S110 is stored in correspondence with the pressing time of the power switch 3 immediately before being turned off. That is, the pressing time of the power switch 3 at the last OFF is stored in correspondence with “0 seconds or more and less than 1 second”, and the memory pressing time “0 seconds” is stored, and in correspondence with “1 second or more and less than 2 seconds” The memory pressing time “1 second” is stored, and the maximum value “10 seconds” is stored corresponding to “10 seconds or more”. Therefore, even if the pressing time of the power switch 3 at the last OFF is 10 seconds or more, the storage pressing time stored in the RAM in step S110 is 10 seconds at the maximum.

  Also in the second embodiment, the process is executed according to the flowchart shown in FIG. 3, and at this time, in step S110, the stored push time corresponding to the push time when the power is turned off measured by the timer is obtained from the table 201. Read and store the push time in RAM. When determining in step S104, it is determined whether or not the switch pressing time when the power is turned on matches the stored pressing time stored in the RAM. Therefore, in the present embodiment, when the power is turned on, the power is turned on when the power switch 3 is pushed and operated for a time that coincides with the stored push time corresponding to the push time immediately before OFF.

  However, when there are a plurality of methods for turning off the power without using such a table 201, the required operation duration at the next power on is determined depending on which method the power is turned off immediately before. It may be determined. If the device has a numeric keypad, such as a cellular phone, for example, the numeric value input by the numeric keypad operation is set as the required operation duration when the power is turned on. You may make it use as "pressing time in OFF". Further, in the menu item displayed by the operation of the menu key 8, the input numerical value is used as the required operation duration when the power is turned on, and is used as the “pressing time immediately before OFF” in the determination of step S104. Good.

In each embodiment, the case where the power is turned on by operating the power switch 3 is shown. However, the present invention is not limited to this. For example, other functions such as turning on the menu display by operating the menu key 8 are provided. It may be applied to a plurality of keys when turned ON.
Further, the present invention may be applied when the shutter key 4 for instructing photographing is also used as a power switch. That is, when the power is turned on by operating the shutter key 4, the power may be turned on when the power is turned off for the pressing time when the power is turned off by the previous operation of the shutter key 4. However, when the power is turned off by the operation of the shutter key 4, a photographing / recording operation is also performed. Therefore, if the pressing time of the shutter key 4 exceeds a predetermined time (for example, 1 second), the power is not used for photographing. It is necessary to devise a method for automatically erasing the photographed image data recorded in the memory by the photographing / recording operation by judging that the shutter key 4 has been operated to turn it off.

  (Third embodiment)

  FIG. 5 is a flowchart showing a processing procedure in the third embodiment of the present invention. When the power is on, the control unit 20 executes processing according to this flowchart based on the program. That is, it is determined whether or not the recording mode key 62 has been pressed (step S201). If the recording mode key 62 is pressed, a timer is started, and a key pressing time that is a time during which the user continues to press the recording mode key 62 is measured (step S202).

  Next, it is determined whether or not the measured key pressing time coincides with time A (A <B), which is shorter than time B used in step S208 described later (step S203). If the key pressing time does not yet coincide with the time A, it is determined whether or not the recording mode key 62 is being pressed (step S204).

  At this time, if the pressing operation of the recording mode key 62 is stopped before the time A is reached, the determination in step S204 is NO, and the process returns to step S201 without performing the recording mode setting process in step S205. If the user continues to press the recording mode key 62, the loop of steps S203 → S204 → S203 is repeated. When the key pressing time of the recording mode key 62 coincides with the time A (step S203; YES), the recording mode setting process is executed to activate each unit necessary for imaging and image recording in the recording mode (step S205). . As a result, a through image is displayed on the liquid crystal monitor 7, and a still image file can be recorded in the flash memory 27 in the recording mode.

  On the other hand, if the result of determination in step S201 is that the recording mode key 62 has not been pressed, it is determined whether or not the playback mode key 61 has been pressed (step S206). If the playback mode key 61 is pressed, a timer is started and a key pressing time, which is a time during which the user continues to press the playback mode key 61, is measured (step S207).

  Next, it is determined whether or not the measured key press time coincides with time B (B> A), which is longer than the time A used in step S203 described above (step S208). If the key pressing time does not yet coincide with the time B, it is determined whether or not the pressing operation of the reproduction mode key 61 is being continued (step S209). At this time, if the pressing operation of the playback mode key 61 is stopped before the time B is reached, the determination in step S209 is NO, and the process returns to step S201 without performing the playback mode setting process in step S210. If the user continues to press the playback mode key 61, the loop of steps S208 → S209 → S208 is repeated. When the key pressing time of the playback mode key 61 coincides with the time B (step S208; YES), the playback mode setting process is executed to activate each unit necessary for displaying the playback image on the liquid crystal monitor 7 in the playback mode. (Step S210). As a result, a reproduced image based on the still image file stored in the flash memory 27 is displayed on the liquid crystal monitor 7.
