A three-dimensional scene sensor comprises: a deformable optical system modifying focal distance by control signal, optics imaging the scene by analog image sensor for depths corresponding to distances; the image sensor comprising a matrix of pixels grouped into sub-matrices of macro-pixels being a sub-assembly of pixels, each macro-pixel operating independently for acquisition and reading of data; a matrix of elementary processors, each macro-pixel directly connected to a dedicated processor wherein pixel data for the macro-pixel are transmitted and processed by the processor, each processor carries out, for each pixel, local processing operations calculating depth information for macro-pixel, the processors operating in parallel and independently such that the depth information is processed and calculated in parallel over all macro-pixels of the image sensor, the processors connected to at least one processing unit allowing calculations using high-level input data, calculated starting from the pixel data directly produced by the image sensor. |
