Abstract

An image sensor circuit comprises a pixel cell array having a plurality of pixel cells arranged along a plurality of column lines, a plurality of readout circuits connected to said column lines, each of which comprises an analog-to-digital converter and a multiplexer for selectively applying an output signal of one of said column lines to said analog-to-digital converter. Between two of said column lines which are connected to a first one of said readout circuits located at a first side of said pixel cell array, there is a column line which is connected to a second one of said readout circuits located at a second side of said pixel cell array opposite to said first side.
