Embodiment Construction

[0018] Please refer to figure 1 , figure 1 It is a schematic diagram of a device 100 for eliminating image blur provided according to a first embodiment of the present invention, wherein the device 100 of this embodiment can be set in a hold type display device (hold type display device), for example: The active matrix liquid crystal display (AMLCD) can be used to eliminate the image blur of the sustain display device, especially to eliminate the above-mentioned sample and hold artifacts.

[0019] The device 100 includes a pixel-based motion detector; for the sake of brevity, it will be referred to as a motion detector hereinafter. In this embodiment, the motion detector is used to perform motion detection on two pixels at corresponding positions in two consecutive images of a video to generate a detection result. Such as figure 1 As shown, the motion detector in this embodiment is a pixel comparison engine (pixelcomparison engine) 110, which detects whether the difference ...

Abstract

The invention relates to a method for eliminating image blurring, which comprises: performing mobile detection on two pixels which are positioned in corresponding positions of two continuous images of a video respectively, so as to generate a detection result; and adjusting the brightness of the two pixels according to the detection result, wherein one pixel is brightened and the other pixel is darkened when the detection result indicates that the two pixels belong to dynamic images.

Description

technical field [0001] The present invention relates to a solution to motion image blur of a hold type display device, in particular to a method and device for eliminating image blur through pixel-based processing. Background technique [0002] For hold type display devices, such as active matrix liquid crystal displays (AMLCDs), motion image blur is a widely discussed issue. Causes of moving image blur include: slow liquid crystal response time, capacitance changes in pixels, and so-called "sample and hold artifacts." [0003] According to known technologies, the former two can be solved by using voltage overdrive and other methods. However, the latter is relatively difficult to deal with because it is a combination of the sampling characteristics of the active matrix liquid crystal display and the smooth motion tracking characteristics of the user's visual system, so it still widely exists in the liquid crystal display on the market. . The solutions for sampling and hol...
