Fig. 1 is referred to, is a kind of schematic flow sheet of picture adjusting method provided in an embodiment of the present invention, wherein, the picture
Face adjusting method can apply to the picture adjusting means for including microprocessor and photosensitive sensor, as shown in figure 1, the picture is adjusted
Section method may comprise steps of：
It should be noted that in embodiments of the present invention, picture adjusting means can be integrated in equipment to be regulated, and (image shows
Show equipment) in, can also independently it dispose, and be connected in a manner of peripheral hardware with equipment to be regulated, treat adjustment equipment to realize
The control of picture regulation.
Step 101, photosensitive sensor obtain the intensity of ambient light, and the intensity of the ambient light got is sent into micro- place
Manage device.
In the embodiment of the present invention, picture adjusting means can obtain the intensity of ambient light by photosensitive sensor, and will obtain
The intensity for the ambient light got is sent to microprocessor.
In the one of embodiment of the present invention, above-mentioned photosensitive sensor can be deployed in the imaging screen of equipment to be regulated
The side of frame, the back side of equipment to be regulated or equipment to be regulated.
In this embodiment, it is photosensitive in order to avoid the light interference during imaging screen playing video of display device
Sensor can be deployed in side of the imaging screen frame of equipment to be regulated, the back side of equipment to be regulated or equipment to be regulated etc.
Image screen playing video when launch light irradiation less than position.
In an alternative embodiment of the invention, when equipment to be regulated for projection picture reproducer (such as projector, laser television,
Below by taking projector as an example) when, photosensitive sensor can be deployed in the imaging screen frame and imaging screen of equipment to be regulated
Portion.
In this embodiment, when equipment to be regulated is projector, photosensitive sensor can be deployed in equipment to be regulated
Image screen frame and imaging inside screen, so as to microprocessor can according to each photosensitive sensor obtaining to the intensity of ambient light
Take situation to determine imaging screen by the region of extraneous light irradiation, and then realize and the picture for imaging screen regional area is adjusted.
It should be noted that in this embodiment, during due to projector to imaging screen projection image, what projector sent
Light can influence to image detection of the photosensitive sensor to ambient light in screen, and therefore, when imaging inside screen, there is photosensitive biography in administration
During sensor, projector needs to send off light pictures to imaging screen when needing to carry out picture regulation, to avoid projector from sending
Light interference imaging screen in detection of the photosensitive sensor to ambient light, the photosensitive sensor improved in imaging screen is external
The accuracy of the detection of boundary's light.
Wherein, projector can send when the off light picture for receiving remote control transmission sends instruction to imaging screen
Off light pictures, or, projector can periodically to imaging screen send off light pictures, such as every 5 minutes to imaging screen
Send an off light picture.
Correspondingly, when projector needs to send off light pictures, can be sent to the microprocessor of picture adjusting means extraneous
Light detection notice message；When microprocessor receives the external light detection notification message, it can be sent to photosensitive sensor extraneous
Light detects triggering command, during so that photosensitive sensor receiving the external light detection triggering command, obtains the intensity of ambient light, and
The intensity of the ambient light got is sent to microprocessor.
The intensity for the ambient light that step 102, microprocessor are got according to photosensitive sensor determines picture adjustment parameter, and
The picture regulating command for carrying picture adjustment parameter is sent to equipment to be regulated, so that equipment response screen to be regulated regulation refers to
Order, picture regulation processing is carried out according to picture adjustment parameter.
, can basis when microprocessor receives the intensity of the ambient light of photosensitive sensor transmission in the embodiment of the present invention
The intensity for the ambient light that photosensitive sensor is got determines picture adjustment parameter, wherein, the picture adjustment parameter can include bright
Spend adjustment parameter, contrast adjustment parameter etc..
In the one of embodiment of the present invention, when the quantity of photosensitive sensor is multiple, microprocessor receives sense
During the intensity for the ambient light that optical sensor is sent, the intensity for the ambient light that can be got according to each photosensitive sensor determines to be used for
Determine the intensity of the ambient light of picture adjustment parameter, for example, photosensitive sensor can be got according to each photosensitive sensor it is outer
The average value of the intensity of boundary's light determines picture adjustment parameter.
In the embodiment of the present invention, after microprocessor determines picture adjustment parameter, it can send and take to equipment to be regulated
Picture regulating command with the picture adjustment parameter, such as sent to the picture processing chip of equipment to be regulated and carry picture regulation
The picture regulating command of parameter；When equipment to be regulated receives the picture regulating command, the picture regulating command, root can be responded
Picture regulation processing is carried out according to the picture adjustment parameter carried in the picture regulating command, such as adjusts picture brightness, contrast.
It can be seen that in the method flow shown in Fig. 1, by disposing picture adjusting means, the picture adjusting means can lead to
