Solid-state imaging apparatus and its signal reading method

Abstract

When pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated. In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (B) by the switching operation in a switching circuit (). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (A) by the switching operation in the switching circuit ().
