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, a logical processing layer independent of the source image layer and the physical display device layer is set between the existing source image layer and the physical display device layer, through which the pixel points in the source image are calculated Map to the coordinate value on the physical display device, and calculate the pixel position of the source image in the video memory of the physical display device according to the coordinate value, and the color depth value and resolution of the physical display device, so that when replacing with ...

The invention is applicable to the field of image processing and provides a method and a system for displaying an image. The method comprises the following steps of: calculating a coordinate value of a mapped pixel point of a pixel point in a source image on a physical display device according to the coordinate value of the pixel point in the source image; calculating the position of the pixel point in the source image in a video memory of the physical display device according to the coordinate value of the mapped pixel point of the pixel point in the source image on the physical display device, the color depth value and the resolution of the physical display device, and storing the pixel point in the source image at the position of the pixel point in the video memory of the physical display device; and displaying the pixel point stored in the video memory of the physical display device. The method and the system can change the physical display device of a different resolution or a different color space by only modifying a corresponding interface of the image displaying method, have a relatively good transportability and reduce maintenance difficulties.
Description
technical field [0001] The invention belongs to the field of image processing, and in particular relates to an image display method and system. Background technique [0002] In the field of image display, existing image display methods generally adopt a two-layer architecture, that is, a source image layer and a physical display layer. When displaying the source image on the physical display device, the existing image display method is to directly display the source image on the physical display device. In this image display method, since the source image is directly displayed on the physical display device, when a physical display device with a different resolution or a different color space is replaced, the image display method needs to be redesigned, so that the image display method can Poor portability, difficult maintenance, and inconvenience to developers. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an im...
