SOLID-STATE IMAGE PICKUP DEVICE AND SIGNAL PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a slid-state image pickup device by which an image with higher resolution can easily be obtained while suppressing an increase in number of pixels and to provide its signal processing method. SOLUTION: In the solid-state image pickup device 10, a signal from an image pickup section 11 of two-dimensional honey-comb arrangement where layout positions of light receiving elements are deviated with each other is fed to a gamma transform processing section 12a of a color signal processing section 12 and an A/D converter section 12b converts the signal into a digital signal (hereinafter called data). A recording and reproducing section 12c stores the data and the data are read from the recording and reproducing section 12c as plane data and fed to the signal processing section 12. The signal processing section 12 uses data equivalent to idle areas of the light receiving elements for virtual pixels in the received plane data and applies signal processing to the pixel data corresponding to items where accurate color reproduction and resolution in horizontal and/or vertical directions are seriously regarded on the basis of the pixel data from the adjacent light receiving elements so as to obtain the signal outputted finally with high quality.
