Abstract
The invention relates to color-image sensors. To benefit both from a good luminance resolution and a color accuracy that is not excessively degraded by the sensitivity of silicon to near-infrared radiation, the invention proposes to produce a mosaic of pixels comprising colored pixels (R), (G), (B), coated with color filters, which are distributed in the matrix, with white pixels (T) not coated with color filters and which are distributed in the matrix. The colored pixels include photodiodes constructed differently from the photodiodes of the white pixels, the different construction being such that the photodiodes of the colored pixels have a lower sensitivity to infrared radiation than the photodiodes of the white pixels.
