DIGITAL IMAGE SIGNAL PROCESSING METHOD, MEDIUM FOR RECORDING THE METHOD, AND DIGITAL IMAGE SIGNAL PROCESSING APPARATUS

摘要

PURPOSE: A digital image signal processing method for removing the noise of an image, a recording medium and a digital image signal processor recording method are provided to improve the reliability by outputting the image efficiently removing the noise. CONSTITUTION: An operation unit derivates the brightness difference of a main pixel about a task domain. A comparison unit compares the brightness difference with the reference. A driving unit(12) drives an optical unit(11). A filtering unit applies an LPF about the pixel included in the LPF process target.
