When an image, such as a subject (object) or a color pictorial, is input through the lens 110, the CD 120 converts the input image into an electric signal, and the automatic second controller 130 transmits the electric signal from the CD 120. The gain is automatically adjusted by receiving the image data converted into a signal. The A / D converter 140 receives the analog video signal whose gain is adjusted from the automatic gain controller 130 and converts the analog video signal into digital image data. The digital signal processor 150 receives a digital image signal from the A / D converter 140 and processes the image into image data that can be output.

The auto focus on the image automatically adjusts the iris of the lens 110 for proper focus.

The memory controller 410 receives the digital image data processed from the digital signal processor 150 and stores the digital image data in the capture memory 420.

When outputting the input image data to a TV or a monitor, the VGA engine 310 drives the memory controller 410 to call the digital image data stored in the capture memory 420, and to the graphic memory 320.

Or CD-ROM 620. If the user wants to output image data stored in the hard disk 610 or the CD ROM 620, the IDE controller 520 reads the image data stored in the hard disk 610 or the CD ROM 620. The microprocessor 510 calls the VGA engine 310 to output the image data read from the IDE controller 520 to the image output device.

When the user wants to transmit the image data stored in the memory unit 400 to the host, the microprocessor 510 drives the memory controller 410 to call the digital image data stored in the capture memory 420, The USB controller 550 is driven to transmit digital image data to a host through the USB 650.
