Mixer and method for mixing multiple dynamic image layers and player

The invention discloses a mixer and a method for mixing multiple dynamic image layers, and a player of the multiple dynamic image layers, and is used for processing pictures having multiple image layers. The method for mixing the multiple dynamic image layers comprises the following steps of: scanning pictures by using scanning lines to obtain the start position and the end position of each imagelayer on the scanning lines; dividing the scanning lines into multiple sections according to the start position and the end position of each image layer on the scanning lines as well as the start position and the end position of the pictures; and mixing a plurality of pixel points of the image layers covered by the section according to the width of each section and the number of the images in thesection so as to generate pixel points for a section mixing picture corresponding to the section.
