Embodiment Construction

[0020] refer to figure 1 , the electronic whiteboard drawing method embodiment of the present invention mainly comprises the following steps:

[0021] Step 101: saving multiple graphics in the whiteboard in the first storage location;

[0022] Step 102: when some of the graphics are selected in the whiteboard, save the selected graphics in a second storage location;

[0023] Step 103: Redraw other graphics in the area where the selected graphics are located to the first storage location;

[0024] Step 104: When redrawing, directly copy all the graphics in the first storage location and the second storage location as images to the screen for display.

[0025] Different from the situation that the electronic whiteboard in the prior art uses a one-time redrawing method when displaying multiple graphics, resulting in slow display, the present invention saves the graphics that need to be changed and the graphics that do not need to be changed separately. When a certain graphics i...

Abstract

The invention discloses electronic white board equipment and a drawing method thereof. The device comprises a handwriting identification module and a graphical operation module, wherein the handwriting identification module is used for identifying a signal input in any position of a white board and carrying out voice playing while identifying; the graphical operation module comprises a first storage unit, a second storage unit, a graph-selecting unit and a drawing unit; the first storage unit stores a plurality of graphs unchanged in the white board; the second storage unit stores graphs to be stored in the white board; the graph-selecting unit is used for storing a graph selected by the first storage unit to the second storage unit when the handwriting identification module identifies a graph-selecting operation; and the drawing unit is used for re-drawing other graphs in a region where the selected graph is arranged into the first storage unit and directly copying all the graphs of the first storage unit and the second storage unit as images to a screen for displaying when re-drawing the graphs. The invention can effectively improve the drawing efficiency of the electronic white board.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to electronic whiteboard equipment. Background technique [0002] The electronic whiteboard is firstly a training and recording device, and its technical development sequence is: 1) a whiteboard for ordinary notices; 2) an electronic copy-type whiteboard for copying the discussion content; 3) it is convenient for demonstration and training and can save the entire Interactive electronic whiteboard for the meeting process. [0003] The so-called copy-type electronic whiteboard means that the content written on the whiteboard can be scanned and printed out in a certain way through simple operations by the user. Its function completion process is the same as the ordinary copying process. First, the image sensor device collects the content on the whiteboard. After the collected signal undergoes certain image processing, it is finally output by thermal, inkjet or other printing metho...
