Abstract
An information processing apparatus acquires an image obtained by photographing a part of the subject, specifies a relative position which part of the subject is photographed to obtain the image, determines a specific area included in the obtained image based on the specified relative position, and calculates an edge amount of the specific area. Then, in a case where the calculated edge amount in the specific area is larger than a first threshold, a character recognition processing is performed on the specific area included in the acquired image.
Claims11
An information processing apparatus, comprising:
- an acquisition unit configured to acquire an image obtained by photographing a part of a subject;
- a specification unit configured to specify a relative position between the obtained image and the entire subject;
- a determination unit configured to determine a specific area included in the obtained image based on the specified relative position;
- a calculation unit configured to calculate an edge amount of the determined specific area;
- and
- a character recognition unit configured to execute a character recognition processing on the specific area in a case where the calculated edge amount in the specific area is larger than a first threshold,
- wherein the first threshold is obtained based on an edge amount of an area corresponding to the specific area of an image whose a certainty factor of a result of the character recognition process being previously executed is equal to or larger than a second threshold.
An information processing method comprising the steps of:
- acquiring an image obtained by photographing a part of a subject;
- specifying a relative position between the obtained image and the entire subject;
- determining a specific area included in the obtained image based on the specified relative position;
- calculating an edge amount of the determined specific area;
- and
- executing a character recognition processing on the specific area in a case where the calculated edge amount in the specific area is larger than a first threshold,
- wherein the first threshold is obtained based on an edge amount of an area corresponding to the specific area of an image whose a certainty factor of a result of the character recognition process being previously executed is equal to or larger than a second threshold.
A non-transitory computer readable storage medium storing a program for causing a computer to function as an information processing apparatus, where the information processing apparatus comprises:
- an acquisition unit configured to acquire an image obtained by photographing a part of a subject;
- a specification unit configured to specify a relative position between the obtained image and the entire subject;
- a determination unit configured to determine a specific area included in the obtained image based on the specified relative position;
- a calculation unit configured to calculate an edge amount of the determined specific area;
- and
- a character recognition unit configured to execute a character recognition processing on the specific area in a case where the calculated edge amount in the specific area is larger than a first threshold,
- wherein the first threshold is obtained based on an edge amount of an area corresponding to the specific area of an image whose a certainty factor of a result of the character recognition process being previously executed is equal to or larger than a second threshold.
