Photographic film player

Abstract

Abstract PURPOSE:To suppress the power consumption of a light source and heating value and to reproduce the result of film photographing with fidelity by deciding the radiation light based on the brightness of a picture for a strobo, storing an output of an image pickup means in a memory and outputting the result. CONSTITUTION:A system control circuit 16 closes a gate 18 and a strobo 10 emitts preliminarily while no SG pulse is sent to a driver 19. Then the gate 18 is conductive and the first SG pulse after the preliminary emitting of the strobo is fed to a CCD 4, from which a generated electric charge is outputted. The output is given to a CDS circuit 11, where noise is eliminated, the signal is converted into a digital picture by an A/D converter 12 and written in a memory 13. The circuit 16 applies D/A conversion so as to check whether or not the brightness of the picture written in the memory 13 is a proper level and the result is fed to a signal processing circuit 15. When the brightness is proper, a picture signal is read from the memory 13 and outputted. When the brightness is not proper, the emitted quantity of light is decided from the level difference with the proper value, the gate 18 is closed and while the SG pulse is not sent to the driver 19, the strobo 10 emitts.
