CA 2055867

An image pick up device has a plurality of rows of light receiving cells, a plurality of vertical transfer registers each located adjacent to respective one row of light receiving cells and a control circuit for controlling said light receiving cells and the vertical transfer registers. The control circuit makes the light receiving cells and the vertical transfer registers carry out a short exposure operation and a long exposure operation continuously, and then reads out both signals sequentially or in parallel to synthesise an expanded dynamic range signal.

Dispositif de prise de vues ayant plusieurs rangées de récepteurs optiques, plusieurs registres de transfert verticaux, dont chacun est situé à côté d'une des rangées de récepteurs optiques, et un circuit de commande desdits récepteurs et registres. Le circuit de commande fait effectuer en continu aux récepteurs et aux registres une opération d'exposition de courte durée et une opération d'exposition de longue durée, puis affiche les deux signaux de sortie successivement ou simultanément en vue de synthétiser un signal à dynamique étendue.
