Abstract

The embodiment of the present invention discloses a panoramic shooting exposure method, which is used to solve the problem that the brightness of the synthesized picture is not smooth during the panoramic shooting. The method includes: the terminal device obtains the sum of the corresponding brightness values ​​of the pre-shot M pictures, The current ambient brightness value to be photographed, M is a positive integer; the terminal device calculates the brightness of the image to be photographed according to the sum of the brightness values ​​corresponding to the M pictures taken in advance, and the current ambient brightness value to be photographed value; the terminal device performs exposure according to the brightness value of the picture to be captured.

Description

technical field [0001] The present invention relates to the field of photographing, in particular to a panoramic photographing exposure method and a terminal device. Background technique [0002] With the advent of the digital age, panoramic photography technology is becoming more and more mature. Panoramic shooting is to combine multiple pictures taken into one panoramic picture. Its basic shooting principle is to search the edge parts of two pictures and overlap the areas with the closest imaging effect to complete the automatic stitching of pictures. [0003] At present, there is no special control on exposure during panoramic shooting, and the exposure is metered through the actual environment. Since panoramic shooting is composed of multiple photos, the brightness value of each picture is tested independently, and the composite photos are exposed separately. Significant changes in light and darkness will lead to more obvious changes in the picture, that is, the bright...
