Abstract:
1. A digital camera comprising: an image sensing element for generating image data of an object; a light emission device for emitting light to illuminate the object during photography; a first detector for detecting contrast of the image data; a focus evaluator for evaluating focus of a lens based on the detected contrast; a lens driver for driving the lens based on the contrast detected by the first detector in response to the focus evaluation; a second detector for detecting luminance of the image data; a light emission controller for executing the light emission of the light emission device to detect the contrast when the luminance detected by the second detector is less than a specific value; a power source for supplying an electrical power to the light emission device, the power source being chargeable, wherein a determination of whether the detected contrast is a maximum value is made in parallel with charging the power source; and a lens drive controller for inhibiting the driving of the lens by the lens driver during charging of the power source.
