Problems solved by technology

If the standard compression method is used to compress, the compression algorithm is complicated, and the MCU measures the decompression speed slowly, which affects the load rate. Unless a high-end MCU is used, it is difficult to achieve the purpose of quickly switching pictures.

Embodiment 2

[0049] Such as figure 2 As shown, an MCU-based background image superimposed dynamic image display method, using the above-mentioned display system, includes the following steps executed in sequence:

[0050] S1: After analyzing the BMP image data by the host computer, the key data is obtained and provided to the MCU; the steps include the following sub-steps:

[0051] S1-1: A 32-bit color BMP image with an alpha channel, read the bitmap data in reverse order with an offset of 54 bytes from the file header;

[0052] The size of the data part is obtained by multiplying the total number of pixels recorded during calculation by the number of bytes required for each pixel; the number of bytes required for each pixel is obtained according to the information header of the BMP picture and the user's choice,

[0053] When the picture to be superimposed is a monochrome picture with a resolution less than or equal to 255x255, the data part is directly provided to the MCU for use; when...

Abstract

The invention relates to the technical field of image display, in particular to an MCU-based system for displaying a dynamic image superimposed on a background image and a display method thereof. An MCU-based background image superimposed dynamic image display system, including a host computer, an MCU and a display; the host computer analyzes BMP picture data and obtains key data for use by the MCU; the MCU analyzes the picture data to obtain Result; the display shows the result. The MCU-based background image superimposed dynamic image display system greatly reduces the amount of image data and improves the convenience and clarity of display.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to an MCU-based system for displaying a dynamic image superimposed on a background image and a display method thereof. Background technique [0002] With the development of technology, the use of TFT screens in electronic products has become more and more common. However, due to the limitation of hardware cost, most of the image displays of embedded products without graphics processing chips are still in the stage of static display. Refreshing the screen of the whole image or partially refreshing the screen is currently the mainstream of image display for these products. For example, if we want to display the number font of 72, there are generally three ways: [0003] The first one is to use font size 72 to display, but the display is not delicate and has a sense of jaggedness. [0004] The second is to refresh the font picture made on the PC side by partial refresh. When ...
