Embodiment Construction

[0021] please see Figure 4 as shown, Figure 4 It is a system diagram of the human eye tracking compensation method disclosed in the present invention. Before being input to the liquid crystal display 320, the input signal 310 is processed by an eye tracking compensation calculation module 410 to obtain an output image 420 that can reduce the occurrence of motion blur. Afterwards, the image 420 is displayed on the liquid crystal display 320 . For example, if the input signal is S, a compensated signal S*(1 / H(x, t)) will be generated after the compensation circuit, where H(x, t) is a model using human eye tracking characteristics A function obtained by simulating the human eye's perceptual response to images on an LCD screen. Output the compensated signal S*(1 / H(x, t)) on the liquid crystal display, then the image signal perceived by the observer is roughly S*(1 / H(x, t))*H(x, t ), the motion blur will be reduced.

Abstract

The invention provides a human eye tracing compensation circuit for a hold-type display device. The human eye tracing compensation circuit comprises a motion vector detection circuit, an analog circuit and a compensation circuit. The motion vector detection circuit receives an input image signal to generate a motion vector. The analog circuit is electrically connected with the motion vector detection circuit, and receives the input image signal and the motion vector to generate a compensation signal of visual images simulating human eyes. The compensation circuit is electrically connected with the analog circuit, and receives the compensation signal and an input image signal to generate a compensation afterimage signal to the display device, so as to lighten the dynamic fuzzy phenomenon caused by the human eye tracing characteristic.

Description

technical field [0001] The present invention relates to a method and device for compensating the dynamic blur phenomenon caused by the characteristics of human eye tracking, in particular to a method and device for processing input image signals to generate The output image of the motion blur phenomenon. Background technique [0002] Recently, liquid crystal display devices have a tendency to completely replace traditional cathode ray pipeline display devices in display applications. With the maturity of liquid crystal display technology, this trend not only occurs in professional display markets such as computer monitors, but also appears in markets such as televisions. display and other entertainment uses on the market. However, due to the influence of liquid crystal response speed, device driving method, display light source, and human eye tracking characteristics, the problem of motion blur when displaying animation is still a defect that needs to be overcome urgently b...
