Abstract
The utility model provides a device for automatically adjusting the screen luminance of a mobile phone, and relates to the technical field of adjusting the screen luminance, in particular to an automatic screen luminance adjusting device for the mobile phone. The device comprises a photosensitive module and a control module, wherein the control module comprises a luminance value storage module, a luminance adjusting module, a pulse signal generator and a luminance value comparison module; and the photosensitive module, the luminance value storage module and the signal output end of the pulse signal generator are respectively connected with the signal input end of the luminance value comparison module, the signal output end of the luminance value comparison module is connected with the signal input end of the luminance adjusting module, and the luminance adjusting module is connected with a backlight module of a screen of the mobile phone. The device causes the mobile phone to automatically adjust the luminance of backlight of the screen according to external environment, without manual operation.
Description
Technical field
The utility model relates to screen intensity regulation technology field, is specifically related to the mobile phone screen automatic brightness regulating device.
Background technology
If external environment light is stronger, then mobile phone screen need be brighter, could allow the user see clearly.If extraneous light is very weak, mobile phone screen needs deepening, could allow the user can not feel dazzling.Therefore need to regulate automatically mobile phone screen brightness, the simple as far as possible device of mechanism.
Summary of the invention
The technical problems to be solved in the utility model is: if external environment light is stronger, regulate mobile phone screen brightness automatically, allow the user can see mobile phone screen clearly.
To achieve the above object of the invention, the technical scheme that the utility model adopted is:
Automatically regulate the device of mobile phone screen brightness, comprise illuminant module and control module, described control module comprises a brightness value memory module, a brightness regulation module, a pulse signal generator and brightness value contrast module; The signal output part of described illuminant module, brightness value memory module and pulse signal generator is connected with brightness value contrast module by signal input respectively, the signal output part of described brightness value contrast module is connected with the signal input part of brightness regulation module, and described brightness regulation module is connected with the mobile phone screen backlight module.
Described illuminant module is the camera of mobile phone.
This practical beneficial effect is: make mobile phone need not to regulate screen backlight brightness automatically according to external environment under the situation of manual operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, illuminant module, 2, control module, 201, the brightness value memory module, 202, brightness value contrast module, 203, the brightness regulation module, 204, pulse signal generator, 3, mobile phone screen backlight module.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
Automatically regulate the device of mobile phone screen brightness, comprise illuminant module 1 and control module 2, described control module 2 comprises with lower module:
One brightness value memory module 201 is used to store the default brightness value that uses for brightness value contrast module 202;
One brightness regulation module 203 is used for the brightness contrast value control mobile phone screen backlight module 3 according to 202 outputs of brightness value contrast module, regulates mobile phone screen brightness;
One pulse signal generator 204 is used to emit pulse signal, and control brightness value contrast module 202 is gathered the frequency of brightness value and generation brightness contrast value from illuminant module 1; And
One brightness value contrast module 202 is used for gathering brightness value with the frequency of pulse signal generator 204 controls from illuminant module 1, presets the brightness value contrast again with in the brightness value memory module 201, at last to brightness regulation module 203 output brightness contrast values.
The signal output part of described illuminant module 1, brightness value memory module 201 and pulse signal generator 204 is connected with brightness value contrast module 202 signal input parts respectively, the signal output part of described brightness value contrast module 202 is connected with the signal input part of brightness regulation module 203, and described brightness regulation module 203 is connected with mobile phone screen backlight module 3.Described illuminant module 1 is the camera of mobile phone.
Operation principle of the present utility model is:
A, brightness value contrast the frequency of module according to pulse signal generator, regularly gather the default brightness value contrast of brightness value and brightness value memory module by illuminant module, calculate the brightness contrast value.
B, brightness regulation module are controlled the mobile phone screen backlight module according to the brightness contrast value of (a) output, regulate mobile phone screen brightness.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
