Image processing apparatus, image processing method and computer readable medium

An image processing method comprising:

• dividing a document image into a plurality of sentence regions;
• recognizing characters included in the sentence regions;
• classifying the sentence regions into a plurality of groups in accordance with sizes of the recognized characters;
• translating a sentence which includes the recognized characters in the corresponding sentence region, into a given language for each of the sentence regions;
• calculating a character size of the translated sentence, based on a size, line spacing, and character spacing of the corresponding sentence region before translation and the number of characters of the translated sentence;
• storing a ratio of the character sizes between at least two of the plurality of groups;
• correcting (i) a size of at least one of the translated characters of any sentence region with characters of the same size classified into a same group such that the character sizes of the translated characters in the same group become equal, and (ii) the size of at least one of the translated characters of any group based on the stored ratio of the character sizes between the at least two of the plurality of groups.

A non-transitory computer readable medium storing a program causing a computer to execute a process for processing an image, the process comprising:

• dividing a document image into a plurality of sentence regions;
• recognizing characters included in the sentence regions;
• classifying the sentence regions into a plurality of groups in accordance with sizes of the recognized characters;
• translating a sentence which includes the recognized characters in the corresponding sentence region, into a given language for each of the sentence regions;
• calculating a character size of the translated sentence, based on a size, line spacing, and character spacing of the corresponding sentence region before translation and the number of characters of the translated sentence;
• storing a ratio of the character sizes between at least two of the plurality of groups:
• correcting (i) a size of at least one of the translated characters of any sentence region with characters of the same size classified into a same group such that the character sizes of the translated characters in the same group become equal, and (ii) the size of at least one of the translated characters of any group based on the stored ratio of the character sizes between the at least two of the plurality of groups.
