Abstract
A solid state image sensor includes an area sensor section having photoelectric conversion pixels arranged in the form of a matrix, a pixel selection section for selecting a pixel of the area sensor section and reading out a video signal, an analog signal processor section for performing signal processing for the video signal, an analog-digital conversion section for converting the processed signal into a digital signal, a digital signal processor section for performing signal processing to convert the digital signal into a digital signal having a predetermined signal format, and an interface section which operates in accordance with an external command, and has the function of selecting a video signal obtained by digitizing a pixel or a signal obtained by performing processing for the luminance and color difference signals of the video signal. These sections are mounted on a single chip.
