ABSTRACT:
To obtain an image pickup device capable of obtaining wide-band R, G, and B signals, R, G, and B signals are generated by a coincidence and matrix circuit using Ye/Cy and Mg/G components of outputs from an image pickup element in units of pixels. A wide-band signal generation circuit generates wide-band signal components from another arithmetic operation using the outputs from the image pickup element. The resultant wide-band signal components are mixed with the R, G, and B signals using an adder and a subtracter, thereby obtaining wide-band R, G, and B signals. Therefore, the wide-band R, G, and B signals suitable for multimedia applications and free from color blurring at a high resolution can be obtained.
