Abstract:
An image reading device which reads a document as an image includes a light source unit, a light receiving unit, a transporting mechanism which relatively transports either one of the light receiving unit or the document, a light reception control unit, and an irradiation control unit which irradiates the light receiving unit with the light from the document during a first light receiving period starting from a beginning point of the charging period and a second light receiving period ending at an ending point of the charging period and which does not irradiate the light receiving unit with the light from the document between the first light receiving period and the second light receiving period.
Abstract:
A color image correcting apparatus includes: a high frequency image generating unit, generating a high frequency image having a high frequency component extracted from a color original image, represented by pixel values of a plurality of channels, for each channel; an average high frequency image generating unit, generating an average high frequency image by assigning an average pixel value, obtained by averaging pixel values of pixels of the channels of the high frequency image in the same coordinate, as pixel values for the channels in the same coordinate, respectively; a low frequency image output unit, generating a low frequency image having a low frequency component extracted from the original image; and a correction image generating unit, generating a corrected image of the original image by superposing the average high frequency image on the low frequency image.
Abstract:
A document reading apparatus includes a housing including a bottom surface formed with an opening for reading a document, and position detection sections disposed on the bottom surface as a pair while interposing the opening therebetween, thereby detecting a position of the document reading apparatus.
Abstract:
Provided is a light source device including: a casing including an irradiation opening which supplies irradiation light to an irradiated object and an outlet which outputs the light reflected from the irradiated object to the outside thereof; a pair of reflection plates of which at least sides facing each other with the outlet interposed therebetween are arranged in the casing; and a light-emitting unit including point light-emitting sources arranged in the vicinity of at least one of the pair of reflection plates in the casing.
Abstract:
A document reading apparatus is provided, which includes a housing having an opening in a reading surface, an imaging portion, arranged within the housing, that reads a document via the opening, and a position detection portion arranged within the opening.
Abstract:
A document reading apparatus includes a housing including a bottom surface formed with a reading opening for reading a document, position detection sections disposed on the bottom surface while interposing the reading opening therebetween to detect a position of the document reading apparatus, and foot sections each having a contact surface being in contact with the document and a detection opening formed in a part of the contact surface, the detection opening facing the position detection section on the bottom surface.
