Abstract: A line head includes first to third light-emitting elements arranged in a first direction; and an optical system that forms images by light emitted from the first to third light-emitting elements on an imaging surface to form images of the light-emitting elements, in which the first light-emitting element is arranged between the second light-emitting element and the third light-emitting element in the first direction; the optical system has a first lens surface that has refractive power and is arranged so as to satisfy a relation of H>0.

Abstract: A document processing apparatus includes a marking detection part that detects a marking written on the form from data read by a first reading part, an attribute name extraction part that extracts a character string described beforehand within or near a marking area of the detected marking as an attribute name, an attribute name detection part that detects the attribute name, extracted by the attribute name extraction part, stored in an attribute information memory and specifies the descriptive position of the detected attribute name from the data read by a second reading part that reads the form on which the attribute values are entered, and an attribute value extraction part that extracts the character string around the detection position of the attribute name detected from the read data, and registers the extracted character string as the attribute value of the attribute associated with the attribute name in the attribute information memory.

Abstract: A character recognition processing system includes a character recognition confidence evaluating unit that evaluates whether confidence of character recognition of a plurality of areas are low or high, a character area classification unit that classifies a first area evaluated low by the character recognition confidence evaluating unit into a plurality of components, a character separation unit that separates the components classified by the character area classification unit into a character component and non-character components, according to information relating to a second area evaluated high by the character recognition confidence evaluating unit, and a first character recognition unit that performs character recognition processing for the character component separated by the character separation unit.

Abstract: An image processing device has a division determination unit. The division determination unit determines the partition number of an image in input image data. The division determination unit calculates the image features of the image in the image data, the features existing in reference areas, and, on the basis of the image features, determines the partition number of the image in the image data.
