Abstract
The embodiments of the present invention provide a method and device relating to multi-picture video image processing, which solve the problem in related art of the deterioration of the vision experience of the conventioneer as the characteristics of each sub-picture can not be satisfied simultaneously. Said method includes: receiving the data code stream of the sub-picture video images from several channels; equalizing the effect of said sub-picture video images with control parameters respectively according to the image characteristics of the sub-picture video images; synthesizing said equalized sub-picture video images to a multi-picture video image. This invention can uniformly adjust each sub-picture video image to the effect with the same image characteristics, which enables the sub-picture video images exhibit the same picture characteristic when be displayed. The display of the multi-picture video image constituted by sub-picture video images achieves whole style harmony and the vision experience of the conventioneer is improved.
