  Here, a series of operations in the photographing sequence according to the present invention will be described using a flowchart. FIG. 4 is a flowchart of an imaging sequence according to the present invention, and FIG. 5 is a flowchart of an imaging recording process according to the present invention.

  In the following, the operation of the imaging sequence of the embodiment will be described in the order of steps from step S101 to step S111 in FIG. 4. Further, in the imaging recording process in step S107, the steps from step S1071 to step S1079 in FIG. It explains while using together.

  When the power button (not shown) in the input device 9 is turned on in the shooting mode, the control unit 8 of the imaging device 1 starts the activation process (step S101). When displaying the liquid crystal display panel, the control unit 8 displays the frequency of the display control clock signal generated by dividing the basic clock signal output from the basic clock 19 by the frequency setting means on the display of the liquid crystal display panel. A clock setting process (step S102) is executed to set the optimum frequency to 15 MHz.

  Next, the control unit 8 controls the display control unit 21 to perform initial setting processing of the liquid crystal display panel to prevent abnormal display of the liquid crystal display panel (step S103) as a step before causing the liquid crystal display panel to enter the display state. Is executed. In the display of the liquid crystal display panel, in the initial setting when the liquid crystal display panel is displayed immediately after the imaging apparatus 1 is started, processing such as stabilization of the power supply circuit, stabilization of the clock signal, establishment of a communication protocol, and the like are performed.

  Next, the control unit 8 controls the display control unit 21 to execute a backlight lighting request process (step S104) after completing the initial setting process of the liquid crystal display panel.

  In response to the initial setting process of the liquid crystal display panel, the control unit 8 executes a display process (step S105) for displaying the image captured by the image sensor 10 on the liquid crystal display panel as a through image.

  Next, the control unit 8 checks whether or not the shooting button in the input device 9 is pressed as input processing (step S106). If the shooting button is pressed, the process proceeds to a shooting / recording process (step S107) described later, and if not, the process proceeds to a power button confirmation process (step S108).

  If the photographing / recording process is completed or the photographing button is not pressed, the control unit 8 confirms the state of the power button as an input process. If the power button is on, the control unit 8 returns to step S105 to continue the shooting standby state, and if the power button is off, the standby request processing for terminating the system of the imaging device 1 (step S109). Execute.

  In this standby request process, the control unit 8 controls the display control unit 21 to place the liquid crystal display panel in a standby state, and discharges electric charges charged in the cells in order to prevent screen burn-in due to residual charges of the liquid crystal display panel. Next, the control unit 8 performs a clock stop process (step S110) for stopping the display control clock signal by the display control means.

  Then, the control unit 8 controls the display control unit 21 to execute the stop process (step S111) of the power supply circuit for driving the liquid crystal display panel and the end process of the entire system of the imaging device 1.

  Further, details of the photographing and recording process in step S107 described above will be described with reference to FIGS. 3 and 4 in the order of steps from step S1071 to step S1079 in the flowchart shown in FIG.

  In response to pressing of the shooting button in the input process of step S106, the control unit 8 starts the shooting and recording process. First, the control unit 8 controls the display control unit 21 in order to put the liquid crystal display panel as the display device 4 in a non-display state and turn off the backlight before the exposure in the image sensor 10 is started. Step S1071) is executed.

  When the control unit 8 puts the liquid crystal display panel in a non-display state, the frequency setting means divides the frequency of the basic clock signal output from the basic clock 19 by the frequency setting means, and sets the frequency of the display control clock signal to the liquid crystal display panel. A high-speed clock setting process (step S1072) for setting the non-display process to 30 MHz for performing the non-display process at a high speed is executed from 15 MHz, which is the optimal frequency in the display.

  The display control unit 21 can process the charge discharge processing by the temporary non-display processing means at a high speed by setting the frequency of the input display control clock signal to 30 MHz. In addition, after the standby request, the control unit 8 controls the display control unit 21 together with the charge discharge process to turn off the backlight.

  Next, the control unit 8 receives the completion of the charge discharge processing by the temporary non-display processing unit of the display control unit 21, and performs display control in order to put the liquid crystal display panel, which is the display device 4, in the non-display state by the display control unit A clock stop process (step S1073) for stopping the clock signal is executed. As a result, the liquid crystal display panel and the backlight which are the display devices 4 are stopped from driving.

  The control unit 8 starts exposure by the image sensor 10 together with the display stop of the display device 4 when the photographing button is pressed, and starts taking in the accumulated data after the exposure is completed. The control unit 8 stores the captured data in the storage device 15 including a DRAM or the like as the image data storage process (step S1074).

  When the image data storage process (step S1074) is completed, the control unit 8 is generated by dividing the basic clock signal output from the basic clock 19 by the frequency setting means when the liquid crystal display panel is brought into the display state. The high-speed clock setting process (step S1075) for setting the frequency of the display control clock signal to 30 MHz so that the re-display process can be executed at high speed is performed again.

  Next, the control unit 8 controls the display control unit 21 to restore the liquid crystal display panel to prevent abnormal display of the liquid crystal display panel by the temporary non-display processing means as a step before the liquid crystal display panel is brought into the display state. The display process (step S1076) is executed at a processing speed based on a frequency of 30 MHz of the display control clock signal. In this re-display process, as a stage before the liquid crystal display panel is displayed again, the temporary non-display processing means stabilizes the clock, establishes a communication protocol, and the like.

  This re-display processing is performed by the clock setting processing as the processing time required to display the through image on the liquid crystal display panel by setting the frequency of the display control clock signal input to the display control unit 21 to 30 MHz. Compared to time, it can be halved.

  Next, the control unit 8 receives the completion of the re-display processing of the liquid crystal display panel by the display control unit 21, and re-displays the liquid crystal display panel, so that the basic clock signal output from the basic clock 19 by the frequency setting means A clock setting process (step S1077) for setting the frequency of the display control clock signal generated by dividing the frequency to 15 MHz, which is the optimum frequency for display on the liquid crystal display panel, is executed.

  Next, the control unit 8 causes the display control unit 21 to resume image display on the liquid crystal display panel, and executes a backlight lighting request process (step S1078) to control the display control unit 21 to turn on the backlight.

  The control unit 8 restarts the driving of the display device 4, compresses the image data already stored in the storage device 15, and then stores it in the memory card 18 via the address data bus 14 and the card interface 17. Data storage processing (step S1079) is executed.

  Here, in order to facilitate understanding of the control of the display device 4 in the imaging device 1 described above with reference to the flowchart, a description will be given using a time chart. FIG. 6 is a time chart relating to the liquid crystal drive sequence of the imaging apparatus 1 according to the present invention.

  As shown in FIG. 6A, in the imaging apparatus 1, the display control clock signal is stopped during a period in which the photographing button is pressed and CCD exposure and data capture are executed, so that the image is picked up by the imaging element 10 described above. The influence of the noise source on the image data generated in this way can be prevented.

  Note that the display control clock stop period is the sum of the CCD exposure time (A in the figure) consisting of the shutter time at the time of shooting and the time (B in the figure) required to capture the image data stored in the CCD. .

  As shown in FIG. 6B, in the imaging apparatus 1, when the shooting button is pressed, the control unit 8 first controls the display control unit 21 to execute a standby request. The display control unit 21 discharges the electric charges charged in the cells in order to prevent screen burn-in due to the residual electric charges of the liquid crystal display panel by the temporary non-display processing means as a step before putting the liquid crystal display panel in the non-display state. Note that the processing time for discharging the charge is 3 [VT].

  [VT] is a vertical processing time in the control of the liquid crystal display panel, and the vertical processing time is calculated according to the frequency of the display control clock signal input to the display control unit 21 and the number of pixels of the liquid crystal display panel. If the liquid crystal display panel of the imaging device 1 having a frequency of 16 MHz and a general number of pixels is employed, 1 [VT] is about 10 ms.

  The control unit 8 controls the display control unit 21 to execute a standby request, puts the liquid crystal display panel in a non-display state, and turns off the backlight after 1 [VT] of the standby request.

  The processing based on the standby request by the temporary non-display processing means is to discharge the electric charges charged in the cells in order to prevent screen burn-in due to the residual charges of the liquid crystal display panel.

  When the discharge of the electric charges charged in the cells by the temporary non-display processing means is completed, the control unit 8 then displays the clock signal for display control in order to make the liquid crystal display panel as the display device 4 non-display state by the display control means. Stop. The clock stop period shown in FIG. 6B is the sum of the CCD exposure time A and the data capture time B. When the data capture is completed, the control unit 8 controls the display control unit 21 to execute a standby state cancel request. The display control unit 21 performs redisplay processing of the liquid crystal display panel by the temporary non-display processing means as a pre-stage for displaying the liquid crystal display panel in order to prevent abnormal display of the liquid crystal display panel. The processing time required for the redisplay process is 4 [VT]. The control unit 8 controls the display control unit 21 to restart the display of the liquid crystal display panel upon completion of the redisplay process, and turns on the backlight after 1 [VT].

  The re-display processing by the temporary non-display processing means is performed to stabilize the clock and perform communication as a step before re-displaying the liquid crystal display panel in order to prevent abnormal display due to residual charges of the liquid crystal display panel, screen burn-in, or occurrence of failure. It establishes the protocol.

In this way, by temporarily stopping the display control clock by setting the display means to the non-display state by the temporary non-display processing means, the image sensor 10 is not affected by the noise source,
When the display device 4 of the imaging device 1 is changed from the display state to the non-display state by the temporary non-display processing means, only the charge discharge processing, the backlight is turned off, and the clock is stopped without turning off the power of the display device Therefore, the processing time can be shortened.

  Further, when changing from the non-display state to the display state, the processing time can be shortened by switching the driving frequency of the liquid crystal display panel at high speed.

  For this reason, it is possible to provide the imaging apparatus 1 that does not cause the photographer to feel stress due to a time lag by speeding up the return to the photographing enabled state.

  Further, by performing the charge discharge process before the liquid crystal display panel is put into the non-display state by the display control unit 21 of the imaging device 1, it is possible to prevent screen burn-in due to residual charges in the liquid crystal display panel.

  In this way, the image pickup apparatus provided with the display device 4 by controlling the control unit 8 by the program stored in the built-in flash memory 16 and performing the temporary non-display processing by the operation of the frequency divider 20 and the display control unit 21. In 1, it is possible to save beautiful image data with less noise, and to enable quick continuous shooting without causing the photographer to feel stress.

  In addition, this invention is not limited to the above Example, A change and improvement are freely possible in the range which does not deviate from the summary of invention.

  For example, in the above embodiment, the sum of the CCD exposure time A and the data capture time B is the clock stop period. It is good also as a period. Depending on the device, it is easy to get noise on the path to transfer analog data to the outside, so if only the data capture time B is set as the clock stop period, effective noise suppression can be performed without lengthening the display off period. Is possible.

  In the above embodiment, only the clock is stopped without stopping the power supply to the liquid crystal display panel at the time of shooting. However, the display on / off processing can be performed at a high speed by speeding up the clock. You may make it stop the power supply to a display panel.

  Further, the user may arbitrarily switch between an operation mode in which the liquid crystal display is turned off during shooting with priority on noise suppression and an operation mode in which noise suppression is not performed with priority on the liquid crystal display during shooting.

  Further, although the display clock is switched from 15 MHz to 30 MHz during the display on / off process, the display clock may be switched to a faster frequency within the allowable range of the liquid crystal display module.

  Further, the frequency may be changed between the display-off process and the display-on process, such as increasing the clock only during the display-off process.
