摘要: An analog signal photo-electrically converted in a pixel of a light receiving area is converted to a digital signal by an ADC. The digital signal is processed by a digital signal processing circuit, and then, successively output as a digital video signal. The digital signal processing circuit has a first signal processing block for detecting and correcting a pixel defect and preventing a noise, and a second signal processing block for restoring apparent resolution lost by the processing by the first signal processing block.

摘要: A shading correcting device includes a correction-coefficient interpolation unit that calculates a color shading correction coefficient used at a position of a pixel at which the color shading correction coefficient is not set among pixels in an image signal by an interpolation process using a color shading correction coefficient set at a predetermined position. A color shading correction coefficient sent to the correction-coefficient interpolation unit is a color shading correction coefficient that is for a first color and corresponds to a pixel value of a second color adjacent to a pixel of the first color.
