By placing A/D converters within image sensors in a parallel arrangement for each vertical column of pixels, analog signals read from vertical signal lines can be directly transmitted to the A/D converters in each column in the shortest amount of time. This makes it possible to read out signals at high speed while simultaneously reducing image quality deterioration that results from noise introduced during analog transmission.
Parallel arrangement of A/D converters by columns
Dual noise cancellation to suppress noise
Noise is also reduced through dual noise cancellation, with high-precision cancellation applied to both analog and digital circuits.
