SIGNAL READOUT METHOD OF SOLID-STATE IMAGING DEVICE AND IMAGE SIGNAL PROCESSING METHOD

摘要

The present invention provides a signal readout method of solid-state imaging device which can simultaneously readouts the signals having different properties that can generate multiple images obtained by capturing the same subject under different capturing conditions from one solid-state imaging device. A signal readout method of solid-state imaging device that is applied to a solid-state imaging device with a color filter array (CFA) and multiple pixels, the method characterized in that a pixel mixture of a different number of pixels is performed for every readout signal in the solid-state imaging device, and a signal after the pixel mixture is readout. The signal after the pixel mixture means a first signal after the pixel mixture that is obtained by performing the pixel mixture of predetermined L pixels (L<=nxm) within (nxm) pixels (n and m are natural numbers) consisting of n pixels in a vertical direction and m pixels in a horizontal direction of the solid-state imaging device, and a second signal after the pixel mixture that is obtained by down sampling pixel signals of (nxm) pixels without performing pixel mixture of (nxm) pixels.
