Abstract

PURPOSE: To rest a shutter speed so that it may be coincident with the movement of an object,when the position of the image of the object is changing, by sampling the image in a time interval corresponding to the shuter speed.
CONSTITUTION: The image signals corresponding to the brightness distribution of the image 8 upon an image sensor 6 are amplified and converted into binary signals by a comparator 12 so that they may be fed to a coincidence detecting circuit 16 and a shift resistor 14. This resistor 14 stores the image information for each sampling interval to according to the shutter speed and is compared at 16 with the binary signals of the image information so that it may be fed to a gate circuit 18. There is left in a counter 20 the number of coincidence bits of the previous and preset reading image information which is compared at 24 with the minimum number of coincidence bits from a fixed data generator 22. The output thus compated is stored in an FF 26 in response to the latch pulses which are generated from a control circuit 34
