<p>Improving the signal processing configuration which has been complicated because the signal processes are achieved by the television camera, there is implemented in a simplified configuration a small-sized, light-weight, and low-priced color image input device without using video capture means. The device produces a high-resolution image with a low power consumption and a reduced noise. The color image input device includes a two-dimensional solid-state imaging device including a combination of color filter arrays including color filters repeatedly arranged with a predetermined repetitious period in the horizontal and vertical directions for producing a multiplex signal including a luminance signal and a plurality of color signals as modulation components representing color information. The device further includes an analog-to-digital (A/D) converter to convert into a multiplex digital signal the multiplex signal thus obtained by combining the luminance signal with color signal components as modulation components corresponding to the color filter arrays, an interface circuit for transmitting the multiplex digital signal, and an image signal processor for separating color image signals of three primary colors from the multiplex digital signal received from the interface circuit via a bidirectional input/output (I/O) port. Particularly, the image signal processor softwarewise achieves the signal processes. <IMAGE></p> |
