ABSTRACT:
An automatic exposure camera having a continuous shooting capability includes a signal generator generating signals in accordance with the operation of an aperture, a measuring unit counting the signals generated by the signal generator for a specified period of time and a storage unit storing the signals generated by the measuring unit. During continuous shooting operations, an initial picture taking operation is controlled in accordance with the signals generated according to the operation of the aperture, and subsequent picture taking operations are controlled in accordance with the signals generated according to the operation of the aperture within a specified period of time during the initial picture taking operation and which are stored in the storage unit. Additionally provided is a method for controlling the aperture operations of an automatic exposure camera having a continuous shooting mode of operation. The method includes, but is not limited to, generating signals in accordance with the operation of an aperture of the camera, counting the signals over a specified period of time and storing the generated signals so that during continuous shooting operations, an initial picture taking operation is controlled by signals generated in accordance with the operation of the aperture, and subsequent picture taking operations are controlled by signals generated according to the operation of the aperture within a specified period of time during the initial picture taking operation and which are stored during the storing step.
