ABSTRACT:
The integrated photoreceptor circuit includes a photosensitive area for picking up light and a processing unit area for processing the signals provided by the photosensitive area. This photoreceptor circuit includes electric contact pads, which are arranged symmetrically solely on the side of the processing unit area, which is juxtaposed with the photosensitive area. The integrated photoreceptor circuit is mounted on a first portion of a flexible substrate. The contact pads of the integrated photoreceptor circuit are electrically connected to electrical connection pads of the printed circuit of the flexible substrate. A second portion of the flexible substrate carries electrical connection terminals, which are connected to the connection pads via conductive paths, arranged in part on a connecting portion between the first and second portions. A through aperture in the first portion may be provided opposite the photosensitive area only of the photoreceptor circuit.
