Abstract
A plurality of analog-to-digital (AD) conversion units is provided in a column signal line connecting commonly to vertical pixel columns. A signal of one pixel is digitized by the plurality of AD conversion units and averaged to achieve noise reduction. Operations for reading signals from a plurality of pixels are performed in parallel for alleviating the decrease of the frame rate.
