Abstract
A character reading method performed by a computer connected to an imaging unit includes repeating processing of recognizing the character included in one-frame image input latest in parallel to input of the moving image, performing matching of a recognition result obtained by every piece of recognition processing in units of characters along a time axis, fixing the recognition result appearing with an appearance ratio larger than a reference value previously decided in the recognition processing continuously performed at least predetermined times, and outputting the fixed recognition result.
Claims8
A character reading program stored on a non-transitory computer-readable medium that causes a computer connected to an imaging unit comprising a moving image photographing function to act as a character reader, a moving image generated by photographing a character string with the imaging unit being input to the character reader, the character reader reading a character in the moving image, the character reading program causing the computer to perform:
- repeating processing of recognizing the character included in one-frame image input latest in parallel to input of the moving image;
- matching of a recognition result in units of characters along a time axis and to fix the recognition result appearing with an appearance ratio larger than a reference value previously decided in the recognition processing continuously performed at least predetermined times;
- and
- outputting the fixed recognition result.
A character reader configured to read a character, a moving image generated by photographing a character string with an imaging unit comprising a moving image photographing function being input to the character reader, the character reader reading a character in the moving image, the character reader comprising:
- a recognition processor that repeats processing of recognizing the character included in one-frame image input latest in parallel to input of the moving image;
- a fixing unit that performs matching of a recognition result of the recognition processor in units of characters along a time axis and to fix the recognition result appearing with an appearance ratio larger than a reference value previously decided in the recognition processing continuously performed at least predetermined times;
- and
- an output unit configured to output the recognition result fixed by the fixing unit.
