Referring to the operation according to the configuration of FIG. 1, when the lens unit 110 adjusts the aperture according to the brightness of the illumination and performs focusing to output an image of the subject incident on the CCD unit 115, the CCD unit 115 may display the image. The image of the subject is converted into an electrical image signal and output to the AGC unit 120. When the AGC unit 120 receives the control signal of the microcomputer control unit 145 and adjusts the gain of the image signal and outputs the result to the A / D converter unit 125, the A / D converter unit 125 performs an analog image for digital signal processing. The signal is converted into a digital signal and output to the selection unit 135 and the image signal memory unit 130.

At this time. For example, if there is an input from the dual screen mode key 160, which is a command input unit, the microcomputer controller 145 outputs a control signal of a light and a read to the image signal memory unit 130 to output the digital signal from the A / D converter unit 125. The video signal is stored in the video signal memory unit 130 and the video signal stored by the read signal is output to the selector 135.

In addition, the microcomputer controller 145 controls the selector 135 to horizontally output the image signal output from the A / B converter 125 and the image signal stored in the image signal memory 130 in the selector 135. Allocate half of each syringe. The video signal data of the half section of the horizontal scanning period output from the selection unit 135 is output to the digital signal processing unit 140. The digital signal processing unit 140 synthesizes the input image signal data, outputs it to the D / A converter unit 165, converts it into an analog signal, and outputs the video. When the user wants to view a screen stored and output from the image signal memory unit 130 and sets a desired screen to view a still image, for example, the user presses a still image selection key 155 that is a command input unit.

At this time, when the microcomputer control unit t45 stops the write control signal to the image signal memory unit 130 and outputs only the read control signal to the image signal memory unit 130, the image signal memory unit 130 stores the image already stored. Only the signal is output to the selector 135.

Under the control of the microcomputer control unit 145, the selector 135 having introduced the output video signal divides the timing of the horizontal scanning period into the front end and the rear end, and selects the video signal output from the video signal memory unit 130 at the front end. In the latter stage, the video signal output from the A / D converter 125 is selected.

The video signal selected by the selector 135 is output to the digital signal processing unit 140. The digital signal processing unit 140 synthesizes the input video signal data and outputs the data to the D / A converter 165 to convert the video signal to a dual screen analog video signal.

When the user wants to see a portion of the still image that is not currently displayed on the dual screen, the image signal data area currently being read in the image signal memory unit 130 is reset through the still image adjustment unit 150.

When the unshown volume of the still image adjusting unit 150 is adjusted, an analog output signal of the volume is converted into a digital signal by the unshown A / D converter of the still image adjusting unit 150 and output to the digital signal to the microcomputer control unit 145.

When the lens unit 210 adjusts the aperture according to the brightness of the illumination and focuses to output an image of the subject incident on the CCD unit 215, the CCD unit 215 converts the image of the subject into an electrical image signal. Output to the AGC unit 220. When the AGC unit 220 receives the control signal of the microcomputer control unit 245 and adjusts the gain of the video signal and outputs it to the A / D converter unit 225, the A / D converter unit 225 converts the analog video signal into a digital video signal. The signal is converted into and output to the digital signal processing unit 230.

At this time, for example, when a filter function is selected and input from the filter mode input unit 240, which is a command input unit, the microcomputer controller 245 controls the digital signal processing unit 230 to read the data of the filter memory unit 235 to digital signal. The processing unit 230 replaces a part of the image signal data included in the specific area of the screen divided by sectors with the data of the filter memory unit 235 to display the filter effect. Some data is replaced to be processed to show the filter effect. The digital video signal is converted into an analog video signal via a D / A converter and recorded or displayed on a TV in a conventional manner.

The AGC unit 320 receives the control signal from the microcomputer control unit 345, adjusts the gain of the image signal, and outputs the result to the A / D converter unit 325. The A / D converter unit 325 converts the analog image for digital signal processing. The signal is converted into a digital signal and output to the selection unit 335 and the image signal memory unit 330.

At this time, for example, when there is an input from the dual screen mode key 360 which is a command input unit, the microcomputer control unit 345 outputs a control signal of a light and a read to the image signal memory unit 330, and then the A / D converter unit 325 The output digital video signal is stored in the video signal memory 330 and the video signal stored by the read signal is output to the selector 335.

In addition, the microcomputer controller 345 controls the selector 335 to horizontally output the video signal output from the A / D converter 325 and the video signal stored in the video signal memory 330 in the selector 335. Allocate half of each syringe. The video signal data selected by half of the horizontal scanning period output from the selecting unit 335 is output to the digital signal processing unit 340.

When the user wants to see a portion of the still image that is not currently displayed on the dual screen, the image signal data area currently being read by the image signal memory unit 330 is reset through the still image adjustment unit 350.

When the unillustrated volume of the still image adjusting unit 350 is adjusted, an analog output signal of the volume is converted into a digital signal by the unillustrated A / D converter of the still image adjusting unit 350 and output to the digital signal to the microcomputer control unit 345.

Half of the syringes are allocated by half and then output to the digital signal processing unit 340. The digital signal processing unit 340 synthesizes the input video signal data and outputs the data to the D / A converter 375 to convert the video signal to a dual screen analog video signal.

On the other hand, for example, when the filter mode is selected and input by the filter mode input unit 365, which is a command input unit, the microcomputer control unit Kin 5 controls the digital signal processing unit 340 and reads the data of the filter memory unit 370 to digital signal. In the processing unit 340, a part of the image signal data included in the specific area of the screen is replaced with the data of the filter memory unit 370 to exhibit a filter effect.
