Description
Technical field
The present invention relates to a kind of multi-media display device, refer in particular to a kind of car multimedia display screen display effect complete certainly
Dynamic regulating system and method.
Background technology
At present, car multimedia brightness of display screen automatically adjusts mode and has the following disadvantages：
1. screen intensity, typically just in the dark when, at such as night, is now dimmed, and is directed to by brightness regulation
Then there is no automatic regulation function under high light, under high light, the problem that do not see occurs.
2. automatic brightness adjustment usually drives lampet or temporally come carry out according to automobile, the side such as temporally adjusting
Formula is usually to press calculation night after 6 pm, calculates daytime, without distinguishing the four seasons, such as 6 pm in summer sky still after 6:00 AM
Very bright, now multimedia display screen luminance-reduction then can affect image quality and display effect.
China Patent Publication No. CN202601141U, publication date on December 12nd, 2012, a kind of entitled " brightness of display screen
A kind of brightness of display screen regulating system is disclosed, including processor, switch and display in the utility model patent of regulating system "
Screen, described display screen includes display screen panel, backlight and backlight control circuit, described backlight control circuit and backlight
Connect, described processor is connected with switch and backlight control circuit.It is disadvantageous in that, this regulating system can only be to driver
Do not use and during multimedia display screen, display screen is dimmed or close, can not be bright come control display screen according to the power of light
Degree.
Content of the invention
The purpose of the present invention be overcome car multimedia display screen in prior art lack can intensity of illumination to external world change
Change the defect carrying out timely automatic brightness adjustment, a kind of car multimedia display screen display effect full-automatic regulation system is provided
And method.
The purpose of the present invention is to be achieved by following technical proposals：
A kind of car multimedia display screen display effect full-automatic regulation method, comprises the following steps：
Step 1, ambient light sensor obtains the information of environment surrounding automobile optical sensor, and transmits information to multimedia control
Device；
Step 2, multimedia controller judges the intensity of surrounding environment light by information, if the intensity of surrounding environment light is higher than to set
First threshold, then multimedia controller control multimedia display screen brightness increase, if the intensity of surrounding environment light be less than set
Second Threshold, then multimedia controller control multimedia display screen luminance-reduction, first threshold be more than Second Threshold.
First threshold is that surrounding environment light is brighter, needs to increase the threshold value of multimedia display screen brightness, and Second Threshold is week
Enclose ambient light dark, it is desirable to reduce the threshold value of multimedia display screen brightness, environment surrounding automobile is obtained by ambient light sensor
The automatically adjusting of the information realization multimedia display screen brightness of optical sensor.
As a kind of preferred version, if the intensity that step 2 also includes surrounding environment light is higher than the first threshold setting, many
Media controller controls multimedia display screen brightness to increase, and the amplitude that brightness increases is with the amplitude of the intensity increase of surrounding environment light
It is directly proportional, if the intensity of surrounding environment light is less than the Second Threshold setting, multimedia controller controls multimedia display screen bright
Degree reduces, and the amplitude of luminance-reduction is with the amplitude proportional of the intensity decreases of surrounding environment light.
The intensity of surrounding environment light proportional with brightness of display screen, surrounding environment light intensity after exceeding first threshold exists
Exceed after Second Threshold proportional with brightness of display screen it is ensured that the display screen moment keep best image state.
A kind of car multimedia display screen display effect full-automatic regulation method, comprises the following steps：
Step 1, ambient light sensor obtains the information of environment surrounding automobile optical sensor, and transmits information to multimedia control
Device；
Step 2, the every s second of the sampler in multimedia controller is once adopted to the information of environment surrounding automobile optical sensor
Sample, within the time setting, the sampled data of the several points to sampler for the multimedia controller carries out taking arithmetic average, if
Mean value is higher than the first threshold setting, then multimedia controller controls multimedia display screen brightness to increase, if mean value is less than
The Second Threshold setting, then multimedia controller control multimedia display screen luminance-reduction, first threshold is more than Second Threshold.
This scheme avoids the rapid blast of short time inner periphery ambient light or the dimmed impact to multimedia display screen brightness,
Only long-time blast or dimmed multimedia display screen just can correspondingly blast or dimmed, guaranteeing display screen best image as far as possible
The life-span of display screen is in turn ensured that while state.
As a kind of preferred version, in step 2, in multimedia controller, the sampled data of the several points to sampler is entered
After row takes arithmetic average, all sampled datas and mean value are compared, if the value of certain sampled data is less than mean value
Or the value of sampled data is more than n times of mean value, then reject this sampled data, remaining sampled data is taken again second flat
Average, if the second mean value is higher than the first threshold setting, multimedia controller controls multimedia display screen brightness to increase, if
Second mean value is less than the Second Threshold setting, then multimedia controller controls multimedia display screen luminance-reduction.
This scheme avoids the rapid blast of short time inner periphery ambient light or the dimmed impact to mean value, for example unexpected
Lightning or entrance tunnel, the mean value of surrounding environment light can be affected by the excessive sampled value of certain point, and then affects the most of the time
The mean value of the sampled value of inner periphery ambient light produces error it is therefore desirable to reject these sampled datas, makes multimedia display screen
The regulation of brightness is more accurate.
As a kind of preferred version, the span of s is 0.1-0.2, and the span of n is 3-5.
A kind of car multimedia display screen display effect full-automatic regulation system, shows including multimedia controller, multimedia
Display screen and ambient light sensor, multimedia controller is connected with multimedia display screen and ambient light sensor by holding wire simultaneously
Connect.
As a kind of preferred version, ambient light sensor is arranged on the roof of automobile, A post, B post, C post, headstock or the tailstock.
The multi-faceted flexible design disposing ambient light sensor is applied to multiple environment and the operating mode of reality.
As a kind of preferred version, a kind of car multimedia display screen display effect full-automatic regulation system also includes the sun
Energy plate, solar panels are connected with multimedia controller.The effect of solar panels energy alternative environment optical sensor, works as solar panels
Luminous energy be converted into electric energy efficiency higher when, show that the intensity of surrounding environment light is higher, when solar panels luminous energy be converted into electric energy effect
When rate is relatively low, show that the intensity of surrounding environment light is relatively low.
The invention has the beneficial effects as follows, car multimedia display screen display effect full-automatic regulation system and method can pass through
Change to the intensity of surrounding environment light accordingly adjusts the brightness of multimedia display screen automatically, and the method adjusting is more intelligent,
Improve the life-span of multimedia display screen.And the system structure is simple, practical.
