Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] In the embodiment of the present invention, by adopting the configurable line buffer during vertical scaling, and assigning the configurable line buffer to the Y channel in the YUV block storage mode, the YUV asymmetrical hardware structure is realized; In the storage mode, the line buffer is allocated to the U and V channels, which realizes the symmetrical structure of YUV and eliminates the phenomenon of asynchronous delay.
[0027] FIG. 1 is a schematic diagram of the structure of various module units when the image display device performs image scaling. For the convenience of description...
