Abstract

The invention relates to an image processing system of digit camera and relative method, wherein said system comprises one delete controller, row-distance prolonging controller, and one effective image interface controller. When the digit image needs to be prolonged, the invention can use row-distance prolonging controller to prolong the output time.

Description

technical field [0001] The present invention relates to an image processing system and method of a digital camera, in particular to an image processing system and method capable of controlling image output time. Background technique [0002] In general, digital cameras can handle dynamic or static image enlargement operations. As far as dynamic images are concerned, when a digital camera is performing a dynamic image enlargement operation, the number of images displayed by the image display unit (such as LCD) per second must reach a certain number so as not to generate noise and visual persistence. This undoubtedly limits the image retrieval unit (such as CCD) to output each row of images to the image display unit within a certain period of time. In addition, in the prior art, when performing image enlargement processing, the image processing unit must reserve a certain bandwidth to process the image to be enlarged, and the larger the magnification, the larger the reserved ...
