Title: Exposure control device for image pickup element
Inventor: KAWAHARA ATSUSHI
IPC: H04N5/225
Filed: 1982-07-07
Abstract: PURPOSE:To attain direct photometry, by using a solid-state image pickup element having an excluding function of unnecessary signal charge and an electronic shutter function for performing exposure control as specified. CONSTITUTION:The solid-state image pickup element 34 has an excluding function of the unnecessary signal charge and the photometry element 36 detects the exposure to the image pickup element 34. Further, a photometry operating circuit 39 operates a shutter time giving an adequate exposure time from an output of the photometry element 36. Moreover, a timing control circuit 315 controls the electronic shutter function of the image pickup element 34. Then, the exposure of the image pickup element 34 is started in synchronizing with a synchronizing signal used to drive it and ends with the elapse of adequate exposure time. Further, after the end of exposure, the signal charge obtained at the exposure is stored under an optically shielded transfer electrode of the image pickup element 34 and read out in synchronizing with the synchronizing signal generated succeedingly. Thus, the direct photometry is attained with the exposure control in this way.
