Information processing apparatus and information processing method

An information processing apparatus comprising:

• an image processor that acquires an image;
• a hardware processor that:
• detects a first region in the image that includes a character and that detects a second region in the image that includes a text-line comprising at least a particular number of first regions, the second region detected based at least in part on the detection of the first region;
• and
• detects a variation in position and attitude of a camera at a time when the image is shot;
• and
• a controller that causes the hardware processor to detect the second region in the image when the variation is less than or equal to a threshold,
• wherein the controller changes a setting of the hardware processor associated with the detection of at least one of the first region and the second region and causes the hardware processor to detect the second region in the image when the second region is not detected by the hardware processor,
• wherein the hardware processor analyzes the image to determine a setting to detect at least one of the first region and the second region in the image,
• wherein the controller causes the hardware processor to determine the setting before execution of the detection of the second region in the image and configures the setting as an initial setting when the variation is less than or equal to the threshold, and
• wherein the controller:
• sets a first dictionary as a character detection dictionary used by the hardware processor to detect the first region in the image when it is determined based on the variation that the camera is in a substantially stationary state;
• and
• sets a second dictionary different from the first dictionary as the character detection dictionary when it is determined based on the variation that the camera is in a moving state of a substantially constant velocity.

• sets a first dictionary as a character detection dictionary used by the hardware processor to detect the first region in the image when it is determined based on the variation that the camera is in a substantially stationary state;
• and
• sets a second dictionary that is different from the first dictionary as the character detection dictionary when it is determined based on the variation that the camera is in a moving state of a substantially constant velocity.
