Character recognition device, character recognition method, and program

A character recognition method comprising:

• a first score calculation step of calculating a first score indicating a likelihood of a character string, or the first score for each of a plurality of candidate character strings which are candidates for character strings included in an input image;
• a character region estimation step of estimating a region corresponding to each character included in the candidate character string among regions of the input image;
• a second score calculation step of calculating a second score indicating a consistency of characters included in the candidate character string on the basis of the estimated region;
• and
• a selection step of selecting one or more character strings from among the plurality of candidate character strings on the basis of the calculated first score and the calculated second score.

A program causing a computer to execute:

• a first score calculation step of calculating a first score indicating a likelihood of a character string, or the first score for each of a plurality of candidate character strings which are candidates for character strings included in an input image;
• a character region estimation step of estimating a region corresponding to each character included in the candidate character string among regions of the input image;
• a second score calculation step of calculating a second score indicating a consistency of characters included in the candidate character string on the basis of the estimated region;
• and
• a selection step of selecting one or more character strings from among the plurality of candidate character strings on the basis of the calculated first score and the calculated second score.
