| 摘要 |
The invention concerns a cell comprising a photosensitive element (1), first addressable means (2) for deactivating said photosensitive element after an exposure phase, second addressable means (9, 10) for, during said exploration phase, retrieving from the cell the luminance signal generated by the photosensitive element, third addressable means (6) for transferring the luminance signal from the photosensitive element to the second addressable means, storage means (cp1 to cp3) for preserving the luminance signal between the exposure phase and the time when the cell is addressed for activating the second addressable means and fourth addressable means (14) for unloading said storage means after the cell has been read. The invention is characterised in that the third (6) and fourth (14) means are placed in a casing arranged in the substrate and having a type of conductivity opposite to that of the substrate. |
