Abstract
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.
