<p>The invention concerns electronic colour image sensors and in particular sensors of very small dimensions enabling miniature photographic cameras or miniature cameras (capable of being incorporated in a portable telephone) to be produced. The sensor is provided with an optical system enabling the image of a scene to be observed to be projected on an array of photosensitive zones provided in a monolithic semiconductor chip integral with the optical system; said optical system includes several optical subassemblies (L1, L2, L3, L4) and the array of photosensitive zones is divided into at least two matrices (M1, M2, M3, M4) capable of being read independently, each optical subassembly being adapted to project onto a respective matrix the whole scene to be observed, two uniform filters of different colours (F1, F2, F3, F4) being arranged respectively above the different matrices to allow through to each matrix a single-colour light.</p> |
