Part related to the present invention rather than entire infrastructure are illustrated only in description, attached drawing.
Embodiment one
The flow chart of a kind of bearing calibration for optical sensor that Fig. 1 is provided for the embodiment of the present invention one, the present embodiment
The situation of adjustment optical sensor is applicable to, this method can be performed by the means for correcting for being used for optical sensor, which can
It is realized in a manner of using software and/or hardware, which can be configured in equipment, such as typically mobile phone, tablet electricity
Brain and computer etc..As shown in Figure 1, this method specifically comprises the following steps：
S110, the reference illumination intensity value that optical sensor is exported when standard sources is irradiated is obtained；
In a specific embodiment of the present invention, standard sources can refer to the artificial light sources simulated under various ambient lightings, make
Production plant or laboratory is non-at-scene can also obtain the illuminating effect basically identical with the light source under these specific environments.Standard light
Source is typically mounted in standard light both, and colour temperature and colour rendering are its measurement indexs, and the illumination launched of standard sources is strong
Angle value is relatively stablized, and in order to which optical sensor in liquid crystal display is allow to export stable illumination intensity value, it is contemplated that by liquid crystal
