摘要
A character recognition device may include an image sensor to acquire image and a data processor configured to segment a character string from the image data. The data processor may be configured to detect positions to segment the characters; set an area to detect a position for segmenting characters; create a first projection of pixel values arranged in the character arrangement direction along which characters are arranged and a second projection of pixel values arranged in an orthogonal to said character arrangement direction; calculate a synthetic threshold value of a first threshold, acquired by applying a discriminant analysis method on said first, X-axis projection, and a second threshold, acquired by applying said discriminant analysis method on said second, Y-axis projection, and take it as a binary threshold for said setting area; and acquire character segmenting positions based on said binary threshold.
