摘要： A still camera utilizes a focus evaluation value based on an imaging video signal to execute an autofocus operation by a hill-climbing control method. A CPU divides a focus area into a plurality of regions to obtain a focus evaluation value from a digital integrator for each of the regions. When the autofocus operation is restarted from the state of a monitoring mode in accordance with a variation of the focus evaluation value, the CPU detects a further hill of the focus evaluation value while forcibly moving a focus lens position always toward a near side, and when a maximal value of the once detected focus evaluation value is less than a certain standard value, additionally executes the autofocus operation.

摘要： A digital camera includes a flash lamp and a CCD imager. A microcomputer first exposes the CCD imager without a light-emission of the flash lamp. Therefore, a luminance evaluation value is calculated by a calculator on the basis of a luminance signal included in a camera signal generated by the CCD imager. The microcomputer succeedingly makes the flash lamp perform a preliminary light-emission, and exposes the CCD imager by {fraction (1/1500)} seconds. The calculator evaluates the luminance evaluation value on the basis of the luminance signal included in the camera signal obtained at this time. Then, the microcomputer calculates a major light-emission amount of the flash lamp on the basis of the two luminance evaluation values obtained in such a manner.
