摘要：PURPOSE:To permit displaying of the image information corresponding tosubjects on a television image receiver by photoelectric conversion thereon and to permitcontinuous image pick-up as well by making an area type solid state image sensingelement disposable on the focal plane of the photographic lens of a camera.
CONSTITUTION:When a SW6 goes on cooperatively with the full opening of a shutter, atransistor Tr1 goes off and the time constant control of a time constant circuit forcontrolling of the shutter is started, and the accumulation of image information
corresponding to objects in a solid state image sensing element SM is started. When thepotential of a C1 rises above a constant value, a Schmitt trigger circuit SHT inverts, andpulses are generated in the terminal A1 of a driving DM, by which the accumulation of theimage information in the element SM is finished. Then a video recorder CK1 startsmagnetic recording, and a counter CNT counts the inversion of the SHT. The count valuethereof is compared with the number of photographs to take which the photographerhas set beforehand in a circuit UST for setting the number of photographs to take andwhen the count value of the CNT is smaller than the set number of the VST, a magnetMg2 for controlling the shutter is kept energized, whereby the closing of the shutter isprohibited.
