Embodiment 1

[0038] image 3 The flow of the method for adjusting the display screen of the terminal provided by the first embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are listed, and the details are as follows:

[0039] As a preferred embodiment of the present invention, before step S20, the following steps are also included:

[0040] Step S10, obtaining the best enhancement factor corresponding to different BV values;

[0041] Wherein, the optimal enhancement factor is the enhancement factor of the gray scale when the clarity of the display screen of the terminal reaches a preset display threshold.

[0042] In the embodiment of the present invention, the camera of the terminal detects the BV value of the environment in different weathers and different time periods, and adjusts the gray scale of the display screen of the terminal when the BV value is different, so that the clarity of th...

Embodiment 2

[0044] Figure 4 The flow of the method for adjusting the display screen of the terminal provided by the second embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are listed, and the details are as follows:

[0045] As a preferred embodiment of the present invention, the above-mentioned step of determining the enhancement multiple of the gray scale of the current display screen according to the BV value is specifically as follows:

[0046] Step S401, converting the BV value to obtain a converted photosensitive value.

[0047] Convert this BV value to a converted photosensitive value f(BV) according to the following function:

[0048]

[0049] It can be seen from formula (1) that the converted photosensitive value f(BV) is a segmented linear function.

[0050] Step S402, obtaining the multiplier enhancement function f3 (f(BV)) of the optimal enhancement factor with respect to t...

Embodiment 3

[0057] Image 6 The flow of the method for adjusting the display screen of the terminal provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are listed, and the details are as follows:

[0058] As a preferred embodiment of the present invention, after step S50, the following steps are also included:

[0059] Step S60, judging the size of the BV value and the preset BV threshold;

[0060] Step S70, when the BV value is less than or equal to the preset BV threshold, detect the remaining power of the terminal;

[0061] Step S80, controlling the backlight brightness of the terminal according to the remaining power.

[0062] In the embodiment of the present invention, in order to save power while improving the clarity of the display screen of the terminal, the brightness of the backlight of the terminal is adjusted according to different remaining power levels.

Abstract

The invention belongs to the field of image display and provides a method for adjusting a display screen of a terminal and a terminal. The method includes the following steps: detecting the photosensitive value of the current environment through the photosensitive sensor of the terminal; obtaining the BV value of the current environment through the camera of the terminal; determining the gray scale of the current display screen according to the photosensitive value and the BV value the enhancement multiple; adjust the grayscale of the currently displayed picture according to the enhancement multiple. In the embodiment of the present invention, when the photosensitive value detected by the photosensitive sensor reaches the maximum detection limit, auxiliary detection is performed through the camera, and the gray scale of the display screen of the terminal is adjusted according to the result of the auxiliary detection, so as to avoid the terminal switching usage scenarios When the display screen becomes white, the user experience is improved.

Description

technical field [0001] The invention belongs to the field of image display, and in particular relates to a method for adjusting a display screen of a terminal and the terminal. Background technique [0002] At present, in order to ensure that the display screen can be seen clearly under strong light, the mobile phone is usually equipped with the function of display enhancement under sunlight, that is, the photosensitive sensor on the mobile phone is used to detect the current photosensitive value, and then adjust the display of the screen according to the current photosensitive value brightness. [0003] The light detected by the photosensitive sensor includes visible light and invisible light. Although the visible light is strong at noon on a sunny day, the invisible light (mainly ultraviolet rays) is strong in the evening and cloudy days. In the high range, and all exceed the measurement limit of the photosensitive sensor configured on the current mobile phone (usually 10...
