example 1

[0077] Example 1: Take the ambient brightness value as an example for the parameter value;

[0078] After obtaining the data stream sensed by part of the Sensor area 34 into the internal memory, it can be converted into a specific format, such as YUV (Y represents brightness, UV represents chroma) data format (YUV ratio RGB (R represents red, G means green, B means blue) occupies a smaller bandwidth, Y means the brightness of the picture (gray scale value), and this fixed-size data is calculated to extract the brightness data of each pixel, and all pixels can be After averaging the luminance data, the average luminance value L representing the picture corresponding to the data stream is obtained;

[0079] In the embodiment of the present invention, the image average brightness values ​​L1, L2...Ln corresponding to different brightnesses EL1, EL2...ELn of the photographing environment (the environment where the camera is located) from dark to bright are obtained (also can be un...

example 2

[0084] Example 2: The parameter value takes the distance between the subject and the camera as an example;

[0085] When the focal length, exposure, contrast and other parameters of the camera are fixed, the object approaches the camera from far to near. When the object exceeds the minimum focusing distance, the imaging picture will change from clear to blurred. This distance is generally within 10cm (determined by the camera) determined by the focal length of the image); the sharpness evaluation function based on the image gray gradient can obtain the sharpness evaluation value of the picture (that is, the value of image sharpness), and then describe the sharpness of the image; within a certain distance range, the image sharpness evaluation The distance between the value and the subject (the above-mentioned shooting subject) is a monotonous single-valued nonlinear relationship. Based on this relationship, the electronic device can judge the distance between the object and the ...

Abstract

The invention provides a parameter value obtaining method and electronic equipment, and the method comprises the steps: obtaining the parameter value of a preset image parameter according to the dataof an image photographed by a camera; obtaining a parameter value of a preset induction parameter according to the parameter value of the preset image parameter and a preset corresponding relationship; wherein the preset corresponding relationship comprises a first corresponding relationship between the parameter value of the preset image parameter and the parameter value of the preset induction parameter. According to the scheme, the camera of the electronic equipment can be used for obtaining the parameter values such as the ambient brightness value of the current environment and the distance value between the shooting main body and the camera; the implementation cost and difficulty of the scheme are reduced, and the problems that in the prior art, cost is high and difficulty is large when electronic equipment achieves light induction, distance induction and other induction functions are well solved.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a parameter value acquisition method and electronic equipment. Background technique [0002] At present, most electronic devices such as mobile phones use special sensor solutions to detect the brightness of the environment and the proximity of the human body: ambient light sensing sensors, distance sensing sensors, or both. Such as figure 1 It is a special sensor layout diagram for electronic equipment such as terminals at present, in which: [0003] a indicates electronic devices such as terminals with functions of ambient light intensity detection and human body proximity. [0004] b represents the distance sensing sensor, which is arranged on the top of the terminal or near the top edge. This sensor can use the infrared light reflected by the human body to realize the distance sensing function. At the same time, the receiving part of the sensor can also...
