Problems solved by technology

Because of the need to decode bmp or jpg files, general low-cost single-chip microcomputer chips cannot meet the requirements
When the lower computer is a display terminal, and the display terminal is equipped with a large-resolution ink screen, then for the ink screen, bmp or jpg files have relatively large pixels, and general low-cost chips cannot meet the memory space, nor can they To store such a large amount of data, it is necessary to improve the performance of the chip, and it needs to be transmitted with Bluetooth o

Embodiment 1

[0047] This embodiment provides a method for compressing the picture bytes of an electronic ink screen, such as figure 1 and figure 2 As shown, the method includes the steps of:

[0048] S1: Obtain the original picture information of the electronic ink screen to be displayed from the host computer;

[0049] S2: Segment the original image information of the electronic ink screen to obtain several byte information;

[0050] S3: Represent several byte information through byte stream; among them, one byte represents eight pixels, and each pixel is represented by one bit;

[0051]S4: Compress the lower six pixels in a byte through the preset compression process to obtain the target compressed pixel data packet;

[0052] S5: Combining the compressed target compressed pixel point data package into a target compressed picture data package, and then transmitting it to the electronic ink screen.

[0053] Specifically, by compressing the image information written into the electronic...

Embodiment 2

[0068] This embodiment provides a compression system for electronic ink screen picture bytes, such as image 3 and Figure 4 As shown, the system includes:

[0069] Obtaining module: used to obtain the original picture information of the electronic ink screen to be displayed from the host computer;

[0070] Segmentation module: used to segment the original image information of the electronic ink screen to obtain several byte information;

[0071] Representation module: used to represent several byte information through a byte stream; wherein, one byte represents eight pixels, and each pixel is represented by one bit;

[0072] Compression module: Compress the lower six pixels in a byte through the preset compression process to obtain the target compressed pixel data packet;

[0073] Transmission module: used to combine the compressed target compressed pixel data packets into the target compressed image data packets, and transmit them to the electronic ink screen.

Abstract

The invention provides an electronic ink screen picture byte compression method and system, electronic equipment and a storage medium, and relates to the technical field of image transmission, and the method comprises the following steps: S1, obtaining to-be-displayed electronic ink screen original picture information from an upper computer; s2, segmenting the original picture information of the electronic ink screen to obtain a plurality of pieces of byte information; s3, representing a plurality of pieces of byte information in a byte stream mode; wherein one byte represents eight pixel points, and each pixel point is represented by one bit; s4, compressing low six-bit pixel points in one byte through a preset compression process to obtain a target compressed pixel point data packet; and S5, combining the compressed target compressed pixel point data packets into a target compressed picture data packet, and transmitting the target compressed picture data packet to the electronic ink screen. According to the method, the communication time of the picture data of the electronic ink screen can be shortened, the picture data transmission reliability is improved, and the communication power consumption is reduced.

Description

technical field [0001] The present invention relates to the technical field of image transmission, in particular to a method, system, electronic equipment and storage medium for compressing picture bytes of an electronic ink screen. Background technique [0002] As a substitute for paper price tags, electronic price tags have been gradually popularized and applied due to their natural advantages such as convenient use, easy unified management, and cost savings. The main function of the electronic price tag is essentially a display device, which has overall low power consumption and ink screen display content, and can flexibly adapt to many application scenarios. However, it is precisely because of its low power consumption requirements and the hardware characteristics of the current ink screen driver interface that, compared with traditional display devices such as liquid crystal displays, it takes a long period of time for feedback from the time when the user triggers the m...
