<p>PURPOSE:To execute second time control by a partial photometry of a desired part, by means of direct photometry, by storing a difference between a mean photometric value and a partial photometric value, and adding this stored value to a direct photometric value. CONSTITUTION:When a partial photometric button is pushed before photographing, a partial photometric value of a photodetecting element 8 is sent to an operation display part 94 through an A/D converter 30, and when the partial photometric button is not pushed, a mean photometric value of a photodetecting element 12 is sent to the operation display part 94. In the operation display part, a difference between the mean photometric value and a mean value of plural partial photometric values is calculated, and is stored. This stored value is supplied to the base of a transistor 42 at the time of direct photometry, and is added to the direct photometric value. In this way, partial photometry is executed by means of direct photometry.</p> |
