Problems solved by technology

[0003] The inventor found that when gray handwriting is used to write content on the screen of a handwriting reading device, if the note lines overlap, the grayscale of the overlapped part in the prior art is the same as the grayscale of the note lines, which cannot reflect the overlap. The simulation effect of deepening the color of the superimposed part is different from the writing effect on paper media

Embodiment 1

[0032] figure 1 A schematic flowchart of a handwriting display method provided by an embodiment of the present invention is shown, and the method is applied to a handwriting reading device. Such as figure 1 As shown, the method includes the following steps:

[0033] Step 110: In the multi-level refreshing mode, monitor the handwriting drawing operation of the stylus pen, and determine the current handwriting area of ​​the stylus pen handwriting.

[0034] The method provided by the embodiment of the present invention is performed in a multi-level refresh mode of the ink screen of the handwriting reading device, such as a 4-level refresh mode, an 8-level refresh mode, and a 16-level refresh mode. In the multi-level refresh mode, in addition to the two colors of black and white, it can also provide different shades of gray display effects between black and white, for example, in the 16-level refresh mode, it can provide 14 different shades of gray display Effect.

Embodiment 2

[0053] When writing by hand, the user may change the setting of the gray level of the handwriting, for example, increase or decrease the gray level. When overlapping and filling multiple times in the same overlapping area, if only the gray levels in the overlapping area are accumulated, when the user increases the current gray level (that is, the first gray level), the current gray level is higher than that of the overlapping area When using the accumulated gray level, directly using the accumulated gray level will not be able to deepen the color displayed in the overlapping area, and cannot better simulate the display effect in the real handwriting process. Therefore, it is necessary to determine the gray level of the overlapping area according to the actual situation.

Embodiment 3

[0071] When the ink screen displays content, it can adopt different grayscale refresh modes, such as 2-level refresh mode, 4-level refresh mode, 8-level refresh mode, and 16-level refresh mode. The higher the gray scale, the slower the refresh rate. In order to improve the fluency of handwriting operation, you can use a lower-order refresh mode. When an overlapping area is generated, switch to a higher-order refresh mode to refresh the overlapping area, so that the color displayed in the overlapping area appears to be deepened.

Abstract

The invention relates to the technical field of computers, and discloses a handwriting display method, handwriting reading equipment and a computer storage medium. The method comprises the steps of monitoring handwriting drawing operation of a handwriting pen in a first multi-stage refreshing mode, and determining a current handwriting area of the handwriting pen; filling the current handwriting area with a gray scale color of a first gray scale level; judging whether an overlapping area exists between the current handwriting area and a drawn previous handwriting area or not; and when an overlapping region exists between the current handwriting region and a drawn previous handwriting region, filling the overlapping region with a gray-scale color of a second gray-scale level, the second gray-scale level being higher than the first gray-scale level. According to the embodiment of the invention, the color deepening effect can be displayed in the note overlapping area, and the writing simulation degree is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a handwriting display method, a handwriting reading device and a computer storage medium. Background technique [0002] Handwriting reading devices (such as e-book readers) generally use ink screens to display content and provide electromagnetic handwriting functions at the same time. Users can write anything on the screen with a stylus. The reader uses a separate layer to display handwriting, and superimposes the handwriting layer on the reading page to show the effect of writing on the reading page. [0003] The inventor found that when gray handwriting is used to write content on the screen of a handwriting reading device, if the note lines overlap, the grayscale of the overlapped part in the prior art is the same as the grayscale of the note lines, which cannot reflect the overlap. The simulated effect of deepening the color of the superimposed part is different from the w...
