Abstract:
1. A camera module for electronically recording images, the module comprising: an image sensor having a plurality of image cells, wherein each image cell is adapted to provide an electric image signal as a function of incident light, and each image cell having a light-sensitive element for generating a light-dependent current, and at least one MOS transistor having a gate terminal and a source-drain path, said MOS transistor being arranged in series with the light-sensitive element, the gate of the transistor being at a fixed potential and the source-drain path being flowed through by the light-dependent current, said module further comprising at least one light source arranged in a vicinity of the image sensor, said light source being adapted to illuminate the image cells without directly illuminating a scene to be recorded, wherein the at least one light source is configured to illuminate the light-sensitive elements whenever a predefined basic brightness exceeds a first threshold value.
