Patent ID: 8194163

Claim:
A solid-state image pickup apparatus, comprising: an XY addressable type solid-state image pickup element in which pixels are arranged in a matrix and color filters are formed at respective pixels and which supports an all-pixel read-out mode and a thinning-out read-out mode; frequency changing means for providing a reduced clock frequency relative to a system clock to provide a constant frame rate for when an all-pixel read-out mode is specified for the solid-state image pickup element, and a reduced number of signal outputs when the thinning-out read mode is specified for the solid-state image pickup element; and driving means for selecting pixels to read out pixel signals, wherein, in said thinning-out read mode, less than all of the pixels in any single column of said matrix are individually output, and less than all of the pixels in any single row of said matrix are individually output and further wherein readout signals are selectively applied during the thinning-out read mode so that only select pixel signals are output from each row and column according to the arrangement of color filters in the matrix.
