Character recognition device, character recognition program, fishery management support terminal device and fishery management support system

摘要

PROBLEM TO BE SOLVED: To provide a character recognition device, a character recognition program, a fishery management support terminal device and a fishery management which can be used even in a harsh environment by enabling accurate character recognition even if reflected light is reflected on a display screen. Provide a support system. SOLUTION: A character recognition device optically recognizes a character from a photographed image of a display screen on which the character is displayed. The binarization means generates a binary image in which the color data of pixels other than the first color data indicating the character color of characters is replaced with the second color data from the captured image. Then, the recognition means recognizes the character indicated by the first color data included in the binary image and outputs it as character information. [Selection diagram] FIG. 10
