An image processing apparatus is configured to extract contour information of a medium area from readout image data, and correct distortion of the medium area based on the contour information. The medium area is an area for image data corresponding to a medium serving as a reading target. The image processing apparatus includes an acquiring unit that acquires the readout image data, an extracting unit that extracts the contour information of the medium area from the readout image data, a displaying unit that displays the contour information so as to superpose the contour information on the readout image data, a detecting unit that detects an instruction of changing a position of the contour information. The extracting unit extracts again the contour information by reflecting the instruction of changing, and the displaying unit redisplays the contour information extracted again by the extracting unit.

A image reading apparatus includes a first placement unit, a second placement unit, a first reading unit, a second reading unit, a rotating mechanism, and a switch-over mechanism that switches over the first placement unit and the second placement unit between a horizontal state and an inclined state. The rotating mechanism rotates the first reading unit and the second reading unit, so that, in the horizontal state, the first image reading unit and the second image reading unit read a medium placed on the first placement unit and a medium placed on the second placement unit respectively, and, in the inclined state, the first image reading unit and the second image reading unit read a medium placed on the second placement unit and a medium placed on the first placement unit respectively.

In an image capturing system, a lighting device includes a base disposed on a medium setting surface on which a medium serving as a reading target is set, an arm extending upward from the base, a top unit extending from the arm in such a manner that the top unit faces the medium setting surface, a placement surface that is provided to the top unit and on which a smartphone (imaging unit) is placed at a position allowing the smartphone to photograph the medium set on the medium setting surface, and a lighting LED that is provided to the top unit and irradiates the medium setting surface.

A linear light source apparatus is provided, being configured to convert light emitted from one light emitting element to light extended linearly, and output thus converted light. There is a lens that diffuses light flux within a predetermined region including the optical axis of the light emitting element, out of the light incident from the light emitting element, at a predetermined diffusion angle in the second direction (x-direction). The light is made to converge with respect to the first direction (y-direction). This converts the light from one light emitting element to light extended linearly and outputs the converted light. As for the second direction (x-direction), it is possible to make the light flux sparse in the predetermined region, and in the region outside thereof, the light flux is rendered to be dense. Therefore, a distribution of light quantity in the longitudinal direction (x-direction) is implemented by controlling the light flux density, upon employing the linear light source apparatus as a light source of the image reading apparatus.

An image capturing system includes an image capturing unit to photograph a medium placed on a medium installation face, a lighting unit disposed in a top unit to irradiate the medium installation face, a lighting control unit to perform driving control of the lighting unit, a scan instruction unit to issue an instruction to perform scanning to photograph the medium and to generate image data of the medium, and a non-readable area determining unit to determine whether or not there is a non-readable area based on an image of the medium obtained by photographing the medium with in a turned-on state of the lighting unit. When there is the non-readable area, the scanning is performed by turning off the lighting unit when the lighting unit was in a turned-on state, and when there is not the non-readable area, the scanning is performed in the turned-on state of the lighting unit.

Image capturing system

An image capturing system includes an image capturing unit configured to photograph the medium on a medium installation face, a lighting configured to irradiate the medium installation face, a lighting control unit configured to control the lighting, and a non-readable area determining unit configured to determine whether there is a non-readable area from which the image capturing unit is unable to read information of the medium due to reflected light of the lighting. The non-readable area is determined based on an image acquired by photographing the medium in a turned-on state of the lighting. When the non-readable area determining unit determines that there is the non-readable area, the medium is photographed in different lighting states set by the lighting control unit, and among the image data generated in photographing process, image data corresponding to the medium is generated by synthesizing areas except an area corresponding to the non-readable area.

A control deviceof the write operation supporting apparatusdisplays, by the projector, operation supporting information for supporting an information writing operation using the documenttoward the imaging area, based on positional information of the documenton the imaging areaacquired by the camera, with relative position relation with the mediumon the imaging areamaintained.

Method and apparatus for supporting user's operation of image reading apparatus

An image processing apparatus includes an imaging unit that images a placed medium as a reading target within an imaging area, and a display unit that displays information toward the imaging area in an overlapping manner. Operation supporting information used for supporting an operation using the placed medium is selected based on information relating to a state of the image processing apparatus or information acquired by the imaging unit, and the selected operation supporting information is displayed toward the imaging area by the display unit.
