Abstract: Embodiments of the present invention disclose an image synthesis method, an image chip, and an image device. The method includes separately obtaining two coordinates, on a first coordinate axis, corresponding to two boundaries that are of each layer in multiple layers of an image frame and that are perpendicular to the first coordinate axis, so as to obtain multiple coordinates corresponding to the multiple layers. The method also includes dividing, by using the multiple coordinates, the image frame into at least two image segments perpendicular to the first coordinate axis; reading, along a direction of the first coordinate axis, the at least two image segments in a time-division manner and according to a scanning sequence. Additionally, the method includes successively performing image synthesis on the at least two image segments according to a time sequence of reading the at least two image segments, so as to generate display data.

Abstract: Embodiments of this application provide an image transmission method and apparatus. The method includes: converting a first high-resolution image into a first low-resolution image, where first resolution of the first high-resolution image is higher than second resolution of the first low-resolution image; encoding the first low-resolution image to obtain a first bitstream; obtaining a second high-resolution image, where third resolution of the second high-resolution image is higher than the second resolution, and the second high-resolution image includes high-frequency information of the first high-resolution image and excludes low-frequency information of the first high-resolution image; obtaining an image residual between the first high-resolution image and the second high-resolution image, where the image residual is used to reflect the low-frequency information of the first high-resolution image; encoding the image residual to obtain a second bitstream; and sending the first bitstream and the second bitstream.
