<p>A method for delaying and outputting a vertical synchronous signal and an image signal processor executing the method are provided to improve back-end chip processing efficiency and output the vertical synchronous signal at the most suitable point of time when encoded data is transferred to a receiving side. An image pick-up apparatus includes an image sensor(110), a sub image signal processor(410), an encoder(420), and a data output unit(430). The image sensor outputs an electric signal corresponding to an external image. The sub image signal processor performs a pre-process corresponding to at least one of filtering and interpolation for the electric signal. The encoder encodes the pre-processed electric signal to generate encoded image data. The data output unit outputs the encoded image data to a receiver(405). The sub image signal processor outputs a delay control instruction for expanding a vertical synchronous signal output period corresponding to a (k+1)th frame following a kth frame processed right after a capture instruction is inputted to the image sensor. The image sensor expands the vertical synchronous signal output period in response to the delay control instruction.</p> |
