Abstract
PURPOSE: To obtain a camera which does not miss the shutter chance even in an uncontrollable region by deciding whether the exposure operated value is within a threshold value or not and selecting either exposure controlling or reoperation based on threshold values.
CONSTITUTION: When a gate circuit 4 decided the selection of shutter second time photographing mode or the like, the sequence control commands for the photographing mode are read out from the ROM5c of a control circuit 5 via the circuit 4 and the correct aperture value is calculated by an arithmetic circuit 8a. Whether this calculated value is within the maximum aperture value and minimum aperture value having been set in a photographing information setting means 2 or not is decided by an operation result discriminating circuit 9 and when it is within the threshold, the calculated aperture value of the circuit 8a is stored in a memory circuit 10, whereby the aperture controlling based on this stored value is accomplished. If it is other than the threshold value, the circuit 8a calculates the shutter second time by the similar arithmetic controlling based on the maximum or minimum aperture value having been set in the means 2, thereby controlling the shutter second time. The same holds true of the aperture priority, thus even in an uncontrollable region the photographing is performed without missing the shutter chance.
