Problems solved by technology

At present, the most commonly used processing methods for static images are: 1) The main control circuit scales the static image and transmits it to the programmable logic device for use and output by the programmable logic device, but it has a slow response speed and changes the static image again. After the size, the main control circuit needs to re-scale and transmit it, further reducing the response speed, and occupying and consuming more image processing resources
2) The main control circuit transmits the static image to the programmable logic device for scaling processing and use by the programmable logic device, but every time the user operates on the window opened by the static image, the main control circuit must transfer the static image Sending to the programmable logic device, its response speed is slow, and the zoom processing unit in the programmable logic device has limited ability to process static images, and there are clear restrictions on the size of the static image and the size of the window. less flexible

Abstract

The embodiment of the invention discloses a static image processing method, device and system and a computer readable storage medium. The static image processing method comprises the following steps: acquiring and storing a static image to a first storage area of a volatile memory; receiving an image display instruction; reading the static image from the first storage area according to the image display instruction; performing scaling processing on the static image to obtain a processed static image; storing the processed static image to a second storage area different from the first storage area in the volatile memory; and reading the processed static image from the second storage area and displaying the processed static image. According to the embodiment of the invention, the response speed of static image processing can be improved, so that the static image processing does not occupy image processing channel resources, and the image processing capability is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a static image processing method, a static image processing device, a static image processing system and a computer-readable storage medium. Background technique [0002] A common function in video processing devices such as video processors, video switchers, etc. includes windowing of input sources. In live activities, a static image is often used as the window canvas background (background, BKG) for opening a window, and there are also application scenarios for opening a window using a static image. The difference between a still image and an input video source is that the content of the still image does not change. At present, the most commonly used processing methods for static images are: 1) The main control circuit scales the static image and transmits it to the programmable logic device for use and output by the programmable logic device, but it has a slow respon...
