Abstract

The embodiment of the invention relates to a background image switching method, which comprises the following steps of: acquiring background image configuration information which comprises background image switching mode information, background image switching sequence information and background image switching interval time information; reading a first background image from a volatile memory in which a plurality of background images are stored according to the background image switching sequence information, and taking the first background image as a current background image; after background image switching interval time information is reached, reading a first background image and a second background image from the volatile memory according to background image switching sequence information; switching a current background image from a first background image to a second background image according to the background image switching mode information; according to the embodiment of the invention, the current background image is switched from the first background image to the second background image, so that the dynamic switching effect of the background images is realized, and the switching effect of the background images is not single any more.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a background image switching method, a background image switching device, a video output card and a video processing device. Background technique [0002] At present, in the field of display technology, video processing devices such as video splicers usually superimpose a background image (also called a base image) on the bottom layer of the layer to be output for foil display, so as to achieve a better display effect of the layer. However, in this display effect method, the display of the background image is a static display. For the user, the static display of the background image has a relatively simple effect and cannot meet the user's needs. SUMMARY OF THE INVENTION [0003] Therefore, in order to overcome at least some of the defects and deficiencies in the prior art, the embodiments of the present invention provide a background image switching method, a backgrou...
