White balance parameter recording and white balance adjusting methods and devices, storage medium, terminal and camera

Abstract

The invention discloses white balance parameter recording and white balance adjusting methods and devices, a storage medium, a terminal and a camera. The white balance parameter recording method comprises the steps of computing an average value of white balance measured values of a plurality of cameras in a current batch; comparing the average value with a current standard value to acquire a comparison result, wherein the current standard value is determined in the previous batch of the current batch, and the current standard value is corresponding to the current white balance parameter; if the comparison result expresses that the offsets of the average value and the current standard value reach a preset threshold, updating the current standard value to be the average value; computing thenew white balance parameter according to a standard camera corresponding to the updated current standard value; and storing the new white balance parameter to the camera firmware which at least comprises the new white balance parameter and the current white balance parameter. According to the technical scheme provided by the invention, the effect of enhancing the white balance standard can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for recording and adjusting white balance parameters, a storage medium, a terminal, and a camera. Background technique [0002] White Balance (White Balance) is an important part of image processing. The so-called white balance means that the white objects in the image can be displayed as white. Human eyes have basically the same perception of the same color under different light conditions. In the morning sun, when looking at a white object, you can feel that it is white; The object can feel that it is still white. This is due to the adaptation of the human brain to the color reproduction of objects under different light conditions. However, shooting equipment such as digital cameras do not have this adaptability, so it is necessary to perform color calibration on the photos taken. Because white has the greatest response to the change of l...

Problems solved by technology

[0004] However, since the standard equipment was selected from the initial production of a small number of equipment, it cannot represent the large number of machines that will be mass-produced later

For different batches of sensors and lenses, even if the hardware parameters remain unchanged, the actual production error will vary with different batches. If the standard equipment / standard value at the beginning of production is always used, the effect of the white balance calibration algorithm will gradually deteriorate
