摘要： The invention relates to an image sensor with N rows of P active photosensitive pixels using MOS technology. The sensor comprises digitizing circuits organized with N rows of P processing circuits, each processing circuit of row rank i and of column rank j comprising a respective sampler for carrying out a correlated double sampling of the signals present on a column conductor of rank j and corresponding to the observation of an image dot over the same integration time for all the rows, and an analog-digital conversion means in order to supply digital values of the analog signals sampled. The sensor is particularly suited to operating in TDI (image scanning and integration) mode.

摘要： The invention relates to scanning linear image sensors with signal integration, in which an image of a line of points from an observed scene is reconstructed by the addition of successive images taken by a plurality of photosensitive lines which successively observe the same line of the scene as the scene moves across the sensor perpendicularly to the lines. The sensor according to the invention uses charge transfer pixels (Pm,i,j) grouped into M groups of N lines; an analog charge summation is carried out in each group; and the results of this summation are read by read circuits (READm) associated with each group, and then digitized and added to those of the other groups.
