Abstract
The present invention relates to an imaging apparatus, which comprises: a pixel array, comprising a plurality of pixels arranged in rows and columns, wherein at least one of the pixels comprises: a first capacitor configured to store a reset signal, and a second capacitor configured to store a pixel signal; a plurality of column circuits, wherein at least one of the column circuits reads the reset signal from the first capacitor, reads the pixel signal from the second capacitor, and generates difference between the reset signal and the pixel signal, wherein the pixel is configured to store the pixel signal to the second capacitor after the reset signal is stored to the first capacitor.
