Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.

Abstract:
A write operation supporting apparatus 1 includes a camera 3 that images a placed document 10 as a reading target within an imaging area 6 and a projector 4 that displays information toward the imaging area 6. A control device 5 of the write operation supporting apparatus 1 displays, by the projector 4, operation supporting information for supporting an information writing operation using the document 10 toward the imaging area 6, based on positional information of the document 10 on the imaging area 6 acquired by the camera 3, with relative position relation with the medium 10 on the imaging area 6 maintained.
Abstract:
An image reading apparatus for bound media includes a placement table, on which a bound medium is placed, a first arm that is opposite to a bound portion of the bound medium, a second arm, a lifting unit that lifts up a turned medium of the bound medium, a second arm moving mechanism that moves the second arm, so that the turned medium lifted by the lifting unit is sandwiched between the first arm and the second arm, an arm moving mechanism that moves the first arm and the second arm, so that the turned medium turns over, a first imaging unit that performs imaging of a side of the turned medium opposite to the first arm, and a second imaging unit that performs imaging of the a side of the turned medium opposite to the second arm.
Abstract:
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.
