Image processing apparatus, image processing method, and non-transitory computer readable medium

摘要

An image processing apparatus determines an orientation of an image according to acquired image information. The image processing apparatus includes an image information acquiring unit, a character string extracting unit, and an image orientation determining unit. The image information acquiring unit acquires image information. The character string extracting unit extracts a character string existing in a rectangular region surrounded by ruled lines or ruled lines and a periphery of the image in a partial area that is a part of the image and that meets a predetermined condition. The image orientation determining unit determines an orientation of the image according to a direction of the character string extracted by the character string extracting unit.

主权项

1. An image processing apparatus determining an orientation of an image according to acquired image information, the image processing apparatus having a processor configured to execute:
an image information storage unit or an image reading unit configured to acquire image information; an input-output unit having a character string extracting unit configured to extract a character string existing in a rectangular region surrounded by ruled lines or ruled lines and a periphery of the image in a partial area that is a part of the image and meets a predetermined condition; and a computer program of the processor having an image orientation determining unit that determines an orientation of the image according to a direction of the character string extracted by the character string extracting unit, wherein the area specification condition group includes a first area specification condition that specifies a first partial area adjoining to a first corner among four corners of the image, a second area specification condition that specifies a second partial area adjoining to a second corner among the four corners of the image, a third area specification condition that specifies a third partial area adjoining to a third corner among the four corners of the image, and a fourth area specification condition that specifies a fourth partial area adjoining to a fourth corner among the four corners of the image, and wherein the partial area specifying unit specifies the first to fourth area specification conditions in a predetermined order until the character string extracting unit extracts a character string existing in a rectangular region in the partial area, which is specified according to the corresponding area specification condition and which is a part of the image.
