Image Signal Processor and Method for Outputting Deferred Vertical Synchronous Signal

摘要

A method of transferring a deferred vertical synchronous signal and an image signal processor executing the method thereof are disclosed. Once the vertical synchronous signal for an m^th frame is inputted from an encoding unit, the method monitors whether image data columns in the quantity of n corresponding to a predetermined process block have been stored, using a count value inputted from the encoding unit, and outputs a corresponding vertical synchronous signal to a receiving part in case the image data columns in the quantity of n have been stored. Therefore, it becomes possible to increase the process efficiency of the back-end chip and to reduce the power consumption.
