Embodiment 1

[0025] An embodiment of the present invention provides a method for adjusting brightness, such as figure 1 As shown, the method includes the following steps:

[0026] Step 101, determine the outline of the highlighted area;

[0027] Optionally, when the user is reading an e-book or browsing a web page, the user sends a partial highlighting request message through a menu option. After receiving the partially highlighted request message sent by the user, the terminal enters the highlighted selection mode, and automatically returns to the e-book page currently read by the user or the web page browsed. In the selection mode, the terminal receives the track drawn by the user through the touch screen; when detecting that the touch screen is released, determines the outline of the highlighted area according to the track.

[0028] Optionally, the user draws the edge track of the area to be highlighted with one stroke on the touch screen of the terminal, where the shape drawn by one ...

Embodiment 2

[0051] An embodiment of the present invention provides a method for adjusting brightness, such as image 3 As shown, the method includes the following steps:

[0052] In step 301, the terminal enters the selection mode of highlighting after receiving the partial highlighting request message sent by the user;

[0053] When a user reads an e-book or browses a web page, he or she sends a partially highlighted request message through the menu option. After receiving the partially highlighted request message sent by the user, the terminal enters the highlighted selection mode and automatically returns to the user's current reading page. eBook pages or web pages you browse.

[0054] Step 302, in the selection mode, the terminal receives the track drawn by the user through the touch screen;

[0055] In the selection mode, the user draws a highlighted area on the screen according to his own needs, and the terminal receives the track drawn by the user through the touch screen; when it ...

Abstract

The invention discloses a method and an apparatus for adjusting luminance, which relate to the technical field of display, and can improve user experience while reducing power consumption. According to the technical scheme provided by an embodiment, the method for adjusting luminance includes steps of determining a highlight area outline according to received trails sketched by a user through a touch screen, establishing, according to the highlight area outline, an image gain template f an original image displayed on the screen; and updating a pixel value of the original image and acquiring a target image according to the pixel value of the original image and the image gain template. The method and the apparatus for adjusting luminance disclosed in the embodiments are suitable for luminance adjustment of a terminal screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for adjusting brightness. Background technique [0002] At present, most display devices use the method of overall brightness adjustment to control the brightness of the display device as a whole, but for the user, the area that can be focused on at the same time is only a part of the display device, which wastes a lot of time. power consumption. In order to reduce power consumption, the prior art also provides a backlight control method, that is, the display device is divided into multiple areas, for example, the display device is divided into four areas or more rectangular areas, and the user can control the backlight according to his needs. Select, turn on or turn off the backlight of a certain area, so that the area that the user pays attention to can increase the brightness, and the area that the user does not pay attention to can reduce the brightness....
