  • Patent number: 10878268
    Abstract: In the case where a character on an object is read by using a mobile terminal having a camera function, an image suitable to OCR is acquired in a short time. An information processing apparatus including a camera, which acquires a moving image by capturing a character string on an object by the camera, sets, for each frame making up the acquired moving image, a search area for character recognition for each character making up the character string, detects a candidate character from the search area, determines whether an evaluation value indicating likelihood of the detected candidate character is stable, and outputs a frame of the acquired moving image in response to the evaluation value is determined to be stable.

  • Patent number: 10304195
    Abstract: An information processing apparatus detects a line segment from an image, determines whether four sides of a plate are detected based on the detected line segment, calculates an aspect ratio of the detected four sides in a case where it is determined that four sides of the plate are detected, and determines whether the aspect ratio satisfies a first condition. In a case where it is determined that four sides of the plate are not detected, the information processing apparatus searches a vicinity of the detected line segment for an object, and determines whether the object satisfies a second condition. The information processing apparatus judges that a recognition target area is included in the image in a case where it is determined that the first condition or the second condition is satisfied.

  • Patent number: 9769246
    Abstract: In an information processing terminal, a web browser, if instructed by a user to call a function for specific data managed by a client, identifies second function information for adapting the specific data to a type processable by a first function called by using first function information belonging to a category corresponding to the function called by a user's instruction. The web browser issues a request for processing the specific data processed with a second function called by using the identified second function information, with the first function, and receives a processing result of the requested processing.
