Patent ID: 7710468

Claim:
An imaging apparatus, comprising: a driving timing signal generator for generating a driving timing signal; an image sensor that is driven to shoot a subject to output an image signal of one frame synchronously with the driving timing signal; an image memory for storing the image signal of one frame; a writing device for writing the image signal of one frame in said image memory synchronously with the output of the image signal from said image sensor; a reproduction timing signal generator for generating a reproduction timing signal; a reading device that starts reading the image signal of one frame out of said image memory synchronously with the reproduction timing signal, to display an image of the subject shot by said image sensor; a synchronizing device for synchronizing the driving timing signal with the reproduction timing signal, while providing such a phase difference between the driving timing signal and the reproduction timing signal that said reading device starts reading the image signal of one frame before said writing device completes writing the image signal of said one frame in said image memory; and a first resolution converting device that crops a designated image cropping area out of the image signal of one frame before being written in said image memory, and converts an absolute resolution of said image cropping area so as to coincide with an absolute resolution of a display screen for displaying the image of the subject, wherein said writing device writes the image signal obtained from said first resolution converting device in said image memory, and said synchronizing device decides the phase difference between the driving timing signal and the reproduction timing signal, taking account of a time necessary for the process in said first resolution converting device.
