Problems solved by technology

If the backlight level is too small, then the adjustment will be a little single, and the backlight switching will only occur when the light intensity changes greatly, but if the light intensity changes small, the backlight switching will not occur, and the backlight adjustment accuracy is poor
If there are too many backlight levels, the backlight resource information stored in the mobile terminal will be too redundant, and it is difficult to quickly find the backlight intensity corresponding to the light intensity. The mobile terminal has a heavy storage burden and takes a long time to adjust.
[0005] It can be seen that the existing automatic backlight adjustment scheme cannot complete high-precision backlight adjustment in a short period of time, which affects the user experience

Embodiment 1

[0024] refer to figure 1 , shows a flowchart of steps of an automatic backlight adjustment method according to Embodiment 1 of the present invention.

[0025] The automatic backlight adjustment method in the embodiment of the present invention includes the following steps:

[0026] Step S102: Determine the current light intensity and the position of the cursor in the brightness slider.

[0027] Currently, the display screen of a mobile terminal has a brightness adjustment function. Usually, the brightness is adjusted by dragging the brightness slide bar through the touch screen, or adjusting the brightness through mechanical buttons. The brightness slider contains multiple points. When adjusting the backlight, the user usually slides the cursor to a specific point in the brightness slider. Therefore, in this step, it is necessary to determine the position of the cursor in the brightness slider. The position value corresponding to the point pointed in the brightness slider. ...

Embodiment 2

[0047] refer to figure 2 , shows a flowchart of steps of an automatic backlight adjustment method according to Embodiment 2 of the present invention.

[0048] The automatic backlight adjustment method provided by the embodiment of the present invention specifically includes the following procedures:

[0049] Step S202: Determine the current light intensity and the position of the cursor in the brightness slider.

[0050] The brightness slider contains multiple points. When adjusting the backlight, the user usually slides the cursor to a specific point in the brightness slider. Therefore, in this step, it is necessary to determine the position of the cursor in the brightness slider. The position value corresponding to the point pointed in the brightness slider bar. The position value can be represented by B.

[0051] For example: the value of the middle point of the brightness slider is 0, the value of the leftmost point of the brightness slider is -1, and the value of the r...

Embodiment 3

[0114] refer to Image 6 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0115] The mobile terminal in the embodiment of the present invention includes: a first determination module 301, configured to determine the current illumination intensity and the position of the cursor in the brightness slider; a second determination module 302, configured to determine the first A logic backlight intensity; conversion module 303, for converting the first logic backlight intensity into the first backlight brightness represented by percentage; curve construction module 304, for constructing an exponential function curve with the first backlight brightness as the base number The third determination module 305 is used to determine the second backlight brightness corresponding to the cursor position in the exponential function curve; the adjustment module 306 is used to determine the second logic backlight intensity corresponding ...

Abstract

The invention provides an automatic backlight adjusting method and a mobile terminal. The method comprises the steps that current illumination intensity and the position of a vernier in a brightness slider are determined; first logic backlight intensity is determined by the illumination intensity and a sample value curve; the first logic backlight intensity is converted into first backlight brightness represented by percentage; an exponential function curve is constructed with the first backlight brightness acting as the base number; second backlight brightness corresponding to the position of the vernier is determined in the exponential function curve; and second logic backlight intensity corresponding to the second backlight brightness is determined, and automatic backlight adjustment is performed according to the second logic backlight intensity. With application of the automatic backlight adjusting method, the accuracy of backlight adjustment can be enhanced.

Description

technical field [0001] The invention relates to the technical field of backlight adjustment, in particular to an automatic backlight adjustment method and a mobile terminal. Background technique [0002] At present, most mobile terminals have the function of automatic backlight, that is, the function of dynamically changing the brightness of the backlight with the intensity of light. During automatic backlight adjustment, the stronger the light, the brighter the backlight needs to be adjusted. This requires the establishment of a mapping between the light intensity and the brightness of the backlight. relationship, automatically adjust the backlight according to the mapping relationship. [0003] In the existing automatic backlight adjustment scheme, a backlight level table including the mapping relationship between light intensity and backlight brightness is set in the mobile terminal, and the mobile terminal performs backlight adjustment according to the backlight level ta...
