Abstract

A photosensor chip includes a light-sensitive region with a plurality of detector elements and a light-insensitive region including a buffer memory. The light-insensitive region is at least double the light-sensitive region. A charge produced at different points in time in the detector elements is successively transferred into the buffer memory for being subsequently read out by a read-out register from the buffer memory. In one embodiment, the buffer memory includes a first and second buffer memory adjoining corresponding sides of the light-sensitive region. The first and second buffer memory can be used alternatively for buffer-storage and read-out.
