Abstract
An image sensor includes a pixel array having a plurality of pixels arranged in rows and columns, a plurality of pixel readout lines coupled to respective pixels, a multiplexing circuit coupled to the pixel readout lines, a plurality of analog-to-digital converters coupled to the multiplexing circuit, and a controller configured to provide pixel readout signals of pixels arranged in a same column to the analog-to-digital converters through the multiplexing circuit for concurrent signal conversion.
