Patent ID: 8687106

Claim:
A camera device having an image sensor for outputting image data and an outputter for adjusting exposure of the image data output from said image sensor and outputting an evaluated value for exposure at that time, said camera device controlling a frame rate of the image data output by the image sensor and performing an auto focusing (AF) controlling processing based on the image data for every frame output from said image sensor, said camera device comprising: a changer which changes from a first target value for normal photographing to a second target value for AF control being smaller than said first target value when a photographing operation is made; an increase controller which continuously increases the frame rate while the evaluated value output by said outputter is being equal to or more than said second target value in response to the change made by said changer, wherein the AF controlling processing is performed on the basis of the image data output at the frame rate increased by said increase controller; and a decrease controller which decreases the frame rate by one when in accordance with the increase of the frame rate by said increase controller, the evaluated value output by said outputter is smaller than said second target value.
