  • Publication number: 20240111150
    Abstract: The present disclosure provides a control method for a display panel, a control device thereof, and a display device. This control method includes: obtaining spatial position coordinates of a pupil of a user; determining coordinates of a gaze point in a display area of a display panel viewed by the user according to the spatial position coordinates of the pupil; determining an area range that the pupil of the user is gazing in the display area according to the spatial position coordinates of the pupil, the coordinates of the gaze point and a preset visual angle; determining a gaze area and a non-gaze area in the display area according to the area range, wherein the gaze area is adjacent to the non-gaze area; and adjusting a first gate driving signal input to the gaze area and a second gate driving signal input to the non-gaze area.

  • Patent number: 9892499
    Abstract: An objective assessment method for a stereoscopic image quality combined with manifold characteristics and binocular characteristics trains a matrix after dimensionality reduction and whitening obtained from natural scene plane images through an orthogonal locality preserving projection algorithm, for obtaining a best mapping matrix. Image blocks, not important for visual perception, are removed. After finishing selecting the image blocks, through the best mapping matrix, manifold characteristic vectors of the image blocks are extracted, and a structural distortion of a distorted image is measured according to a manifold characteristic similarity. Considering influences of an image luminance variation on human eyes, a luminance distortion of the distorted image is calculated according to a mean value of the image blocks.

  • Publication number: 20170177975
    Abstract: An image quality objective evaluation method based on manifold feature similarity is disclosed, which firstly adopts visual salience and visual threshold to remove image blocks which are unimportant to visual perception, namely, uses roughing selection and fine selection; and then utilizes the best mapping matrix after block selection to extract manifold feature vectors of image blocks which are selected from original undistorted natural scene images and distorted images to be evaluated; and then measures the structural distortion of distorted images according to manifold feature similarity; and then considers effects of image brightness changes on human eyes and obtains the brightness distortion of distorted images based on an average value of image blocks, and finally obtains quality scores according to structural distortion and brightness distortion; which allows the method of the present invention to have a higher evaluation accuracy, and also expands the evaluation capacity to various distortions.
