DEVICE FOR PROCESSING AN IMAGE AND A METHOD THEREOF, CAPABLE OF IMPLEMENTING AN INCREASE OF A BATTERY LIFE AND A REDUCTION OF A VEHICLE MAINTENANCE COST BY REDUCING A WHOLE CONSUMPTION POWER OF 'A NAVIGATION SYSTEM HAVING A DISPLAY DEVICE'

摘要

PURPOSE: A device for processing an image and a method thereof are provided to reduce a power consumption of a display device without a degradation of an image display quality by applying 'a compensated gradation in which an input gradation contrast of an input image gradually reduces to an edge of a screen', and by applying an input gradation in case of a central pixel of a screen.;CONSTITUTION: A device for processing an image and a method thereof comprise the following steps: a pixel coordinate detector (110) inputs 'input pixel data having an input coefficient value', and detects coordinate data of the input pixel data; a Gaussian filter computation unit (130) computes the input coefficient value and 'a Gaussian filter coefficient which is elicited from a memory unit (120)', and generates 'output pixel data having a compensated coefficient value'; and the compensated coefficient value forms 'a Gaussian distribution in which a rate of the input coefficient value comparison the compensated coefficient value reduces from a central area of a screen to a peripheral area'.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Pixel coordinate detector; (120) Memory unit; (130) Gaussian filter computation unit; (210) Driving unit; (220) Display unit
