Problems solved by technology

[0002] In the existing face-based light metering methods, in order to ensure that as many faces as possible are included in the light metering area, the size of the face frame must be increased, so that more or less in the face metering The area contains background and hair data. Because the brightness information of the background changes greatly under different scenes and lighting conditions, and the influence of hair and eye color, the metering based on the face is very unstable and extremely unstable. Greatly affects the effect of metering

Embodiment Construction

[0091] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0092] Such as figure 1 As shown, a kind of light metering method based on skin color recognition of the present invention comprises the following steps:

[0093] A. Capture the image data acquired by the camera;

[0094] B. performing face detection on the image data;

[0095] C. Determine whether a face is detected, if yes, go to step D, otherwise jump to step A;

[0096] D. Perform skin detection and skin color probability statistics according to the detected face position, and obtain the skin color probability and the center point position of the...

Abstract

The invention relates to a photometry method and system based on skin color recognition. Face detection, skin detection and skin color probability counting are carried out on image data captured by a camera, and the skin color probability obtained by counting and the center point position of the highest skin block are compared with original system photometry center points so as to determine the final photometry center points. The photometry method and system are high in pertinence, can eliminate the influence of face non-focus areas such as backgrounds, the hair and the eyes, and make the photometry effect be more stable and natural.

Description

technical field [0001] The invention relates to a photometric method and a photometric system, in particular to a photometric method based on skin color recognition and a photometric system applying the method. Background technique [0002] In the existing face-based light metering methods, in order to ensure that as many faces as possible are included in the light metering area, the size of the face frame must be increased, so that more or less in the face metering The area contains background and hair data. Because the brightness information of the background changes greatly under different scenes and lighting conditions, and the influence of hair and eye color, the metering based on the face is very unstable and extremely unstable. Greatly affected the effect of metering. Contents of the invention [0003] In order to solve the above problems, the present invention provides a photometry method and photometry system based on skin color recognition, the photometry is mor...
