Embodiment Construction

[0058] The inventors of the present invention have found through research that the entire backlight area can be divided into m×n (m and n are both positive integers) mutually independent areas, and each area corresponds to one or several LEDs (Light-Emitting Diodes, which emit light). Diode), and each area is controlled and adjusted separately as the smallest adjustment unit (or the smallest backlight structural unit).

[0059] If the brightness of the smallest backlight structural unit is represented by Aij, i represents the number of rows, 1<<i<<m; j represents the number of columns, 1<<j<<n; Aij represents the value of row i and column j in the matrix The brightness of the minimum backlight structural unit, the value of Aij can be adjusted according to the user's actual demand for the brightness of the displayed image. Then the entire backlight area can be represented by the following luminance matrix (hereinafter referred to as "the first matrix"):

Abstract

Embodiments of the invention provide a backlight adjusting method and device, a backlight adjusting computing device, a display device and a storage medium. The method includes the following steps: determining a region of attention and a region of non-attention in an image on the basis of points of attention of a user in the image; and conducting adjustment with first precision on backlight brightness of the region of attention and conducting adjustment with second precision on backlight brightness of the region of non-attention. The method can realize contrast adjustment of the region of non-attention and more refined adjustment of the dynamic region of attention, better accords with attention situations of the user during practical applications, greatly improves the visual experience ofthe user, simplifies a control process, and reduces the power consumption while satisfying needs of the user.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to a backlight adjustment method, device, computing device, display device and storage medium. Background technique [0002] In the traditional backlight brightness adjustment technology, in most cases, it is only adjusted for the backlight area corresponding to the user's visual attention area on the displayed image. All R&D personnel focus on developing various algorithms to modify this area, while the non-focus area The corresponding backlight area is seldom adjusted, and even the adjustment usually only reduces the brightness of the backlight area in the non-focused area, or even turns it off. [0003] Although the non-concerned area is not the core area observed by the user, it is not the blind area of ​​the user's field of vision. Its brightness characteristics still affect the user's viewing experience. The overall display effect affec...
