METHOD FOR RECOGNIZING PAGE OF AUDIO BOOK DEVICE

摘要

A method for recognizing pages of an audio book device is provided to enable current pages to be accurately recognized regardless of changes in a book height and optical voltage sensor value, etc. by determining black or white color of each recognition code by using a page recognition sensor. Each code value in a page code unit(10) formed at each page of an audio book is sequentially inputted by using a page recognition sensor. The code values are divided into a first group and a second group by using a clustering algorithm. A code belonging to the first group is determined as a black color and a code belonging to the second group is determined as a white color. Then, a current page number is evaluated on the basis of the determination result.
