Embodiment Construction

[0029] figure 1 It is a schematic flow chart of the color recognition method of the present invention. Such as figure 1 As shown in , a color recognition method of the present invention includes a color learning stage and a color recognition stage. The color learning stage includes steps 110-140, and the color recognition stage includes steps 150-170. The steps in the color learning stage are used to prepare a database of color images and related voice files, and the database will be used in the color recognition stage later.

[0030] Such as figure 1 As shown in , in step 110, a plurality of frames of color images are prepared for printing on at least one sheet of paper. Each color image printed on a piece of paper must have a distinctive color to distinguish it from other color images. In step 120, digital signals representing the red, green and blue components of the distinct colors of each color image are obtained. In step 130, the acquired digital signal with a voic...

Abstract

A color recognition method is provided, including a color learning phase and a color recognition phase. The color learning phase further includes the steps of: preparing a plurality of color images printed on at least a sheet of paper; for each color image of the plurality of color images, obtaining the digital signals representing the red, green and blue components of the color; associating the digital signals with an audio file related to the color image; and storing the digital signals with associated audio file to a database in the storage device. The color recognition phase further includes the steps of: obtaining the digital signals representing the red, green and blue components of an color image printed on a sheet of paper; comparing the digital signals representing the color image to a pre-stored database in a storage device; if a match is found, playing the associated audio file.

Description

technical field [0001] The present invention relates to color recognition technology, in particular to an economical color recognition method applicable to printed educational materials. Background technique [0002] Today's electronic teaching materials use a variety of technologies to enrich the content of teaching materials, so children can learn different subjects in a more vivid way. For example, color recognition technology combined with audio output can correctly teach children to recognize the colors of objects printed on educational materials. When a user places a reading device, such as a pen-like device, on an image printed on a teaching material, the audio information related to the image can be played, so that Users can hear the voice content and learn from it. Moreover, the technology used in this teaching material can also be applied to products used by vision-impaired users. [0003] The traditional way to achieve color recognition in teaching materials us...
