Benefits of technology

This patent describes an image processing device that prevents the display from showing unnecessary images. The device uses a second compensator to control the scaling of the unreduced image data. This helps to improve the overall quality of the displayed image.

Problems solved by technology

An image sticking may occur on display devices by degradation of pixels as a result of driving the pixels over time.

Embodiment Construction

[0039]Hereinafter, the invention will be explained in detail with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0040]It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0041]It will be understood that, although the terms “first,”“second,”“third” etc. may be used herein to describe various elements, components, regions, layers and / or section...

Abstract

An image processing device includes an image determiner which determines whether an image data is a still image or a motion picture image, a first compensator which gradually changes a scaling ratio of the image data of which a center part is fixed and a second compensator which divides the image data into a plurality of sub-image data and change a scaling ratio of the sub-image data.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2015-0096244, filed on Jul. 7, 2015, the content of which in its entirety is herein incorporated by reference.BACKGROUND[0002]1. Field[0003]Exemplary embodiments relate generally to an image processing device. More particularly, exemplary embodiments of the invention relate to an image processing device and a display device having the same.[0004]2. Description of the Related Art[0005]A flat panel display (“FPD”) device is widely used as a display device of electronic devices because the FPD device is relatively lightweight and thin compared to a cathode-ray tube (“CRT”) display device. Examples of the FPD device include, for example, a liquid crystal display (“LCD”) device, a field emission display (“FED”) device, a plasma display panel (“PDP”) device, and an organic light emitting display (“OLED”) device. The OLED device has been spotlighted as next-generation display devices because the OLED device has vari...
