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.

Image sensor circuit

An image sensor circuit comprises at least one pixel cell for providing an output signal which is variable according to illumination of said pixel cell between a maximum and a minimum level, an analogue-to-digital converter for converting output signals from said pixel cell into digital data, and an offset signal source for providing an offset signal having a level between said maximum and minimum levels. The analogue-to-digital converter is fully differential and is connected to said pixel cell and to said offset signal source.
