Problems solved by technology

[0004] However, in the process of realizing the present invention, the inventors found that there are at least the following defects in the prior art: the existing inverse color processing method is to perform inverse color processing when drawing pictures, and it is necessary to perform color inversion processing for each layer in each layer. Performing inverse color calculation for one pixel point is a large amount of calculation and low in efficiency; secondly, when the data format of the layer data of each layer is inconsistent, it is necessary to extract the color components of the color values ​​in various formats and perform inverse color calculation separately. Combining the color value of a pixel, the logic complexity of inverse color processing will further increase

Abstract

The invention discloses an anti-color display method of a handwriting reading device and the handwriting reading device, and the method is realized based on a driving program of a system layer of thehandwriting reading device, and comprises the following steps: receiving layer data of each layer transmitted by an application layer, and carrying out merging processing on the layer data of each layer to obtain to-be-displayed picture data; Querying a color inversion processing switch state, and if the color inversion processing switch state is an on state, performing color inversion processingon the to-be-displayed picture data; and outputting the to-be-displayed picture data subjected to the color inversion processing to an electronic ink screen for displaying. With the adoption of the mode, the mode is adopted;, color inversion processing is directly carried out on to-be-displayed image data obtained after the image layers are combined at the system layer by utilizing a driving program; Compared with the prior art, the method has the advantages that the image layer data of each image layer does not need to be subjected to color inversion processing, the complexity and the calculation amount of color inversion processing can be reduced, the efficiency of color inversion processing is improved, and meanwhile the problem that the color inversion processing difficulty is increased due to inconsistent image layer data formats can be avoided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a reverse color display method of a handwriting reading device. Background technique [0002] Inverting the color of the image is essentially to invert the color of the image, and it is realized by inverting the image data. For example, the R, G, and B color components of the color image are respectively inverted. If the quantization level is 256, then the R, G, and B component values ​​of the new image are 255 minus the R, G, and B component values ​​of the original image. [0003] For existing handwriting reading devices based on electronic ink screens, the reverse color display of screen images is implemented at the application layer. After the application layer obtains the layer data of multiple layers, it performs inverse color processing on the layer data of each layer, and then transfers the layer data of each layer after the inverse color processing to the syste...
