Patent ID: 7783191

Claim:
A digital camera comprising: an image sensor driver that drives an image sensor by outputting a driving signal corresponding to a moving image, the driving signal including a clock pulse signal that is used to successively read image-pixel signals from said image sensor; a photographing processor that carries out an exposure in accordance with the operation of a release button, in order to record a still image; a driving signal controller that outputs a control signal associated with a change of the driving signal to said image sensor driver in accordance with the operation, an output timing of the control signal synchronizing with the clock pulse signal, said image sensor driver outputting a driving signal corresponding to a still image in accordance with an update timing that synchronizes with the clock pulse signal; and a timing adjuster that shifts at least one of the output timing of the control signal and the update timing of the driving signal, from a synchronization timing of the clock pulse signal, in accordance with the operation, wherein: the image sensor driver updates the driving signal in accordance with an update signal that rises in the image sensor driver, based on the control signal from the driving signal controller, while synchronizing with the clock pulse signal, the timing adjuster shifts an output timing of the update signal from the synchronization timing of the clock pulse signal so as to shorten an interval between the output timing of the control signal and the output timing of the update signal, and the image sensor driver outputs the driving signal of a still image from a next field interval in accordance with the shifted update signal.
