摘要： An image reading apparatus includes a conveying unit to convey a document, first and second reading units, a reception unit, a selection unit, and a setting unit. The first reading unit generates image data form a document first side and the second reading unit generates image data from a second side in parallel with the first reading unit reading. The reception unit receives settings regarding a size, an orientation, and a document opening direction of the document. The selection unit selects either a first reading method causing the first and second reading units to read per the set size, and a second reading method causing the first reading unit to read the first side per the set size and causing the second reading unit to read an entire second side. The setting unit sets image data corresponding to the document second side reading by the second reading method.

摘要： Devices and methods are described that facilitate the creation of a digital image of an object using a custom scan area size. Custom scan area sizes are stored and displayed so as to eliminate cumbersome steps such as measuring irregularly-sized objects more than once or processing the digital image after scanning the object to remove undesirable “white space.”

摘要： An image reading device includes: a CCD for reading an image on a document to output an image signal; a light source for switchingly emitting visible light and non-visible light; and lighting control means for controlling lighting periods of the light source. The lighting control means is adapted to perform control such that a first light source lighting period for applying non-visible light is longer than a second light source lighting period for applying visible light. The image reading device also includes splitting means for splitting the image signals outputted from the CCD into an image signal upon application of visible light and an image signal upon application of non-visible light.

摘要： A method of projecting an image onto a viewing surface uses scanning projector, such as a laser-beam-steering pico projector, which scans a laser beam across the viewing surface. Each pixel area on the viewing surface which is included within images defined by a high intensity display digital video data, and each pixel area on the viewing surface which is included within images defined by a low intensity display digital video data are scanned. The projector beam illuminates each pixel area on the viewing surface which is included within images defined by the high intensity display digital video data for a greater period of time than is spent illuminating each pixel area on the viewing surface which is included within images defined by other digital video data.

摘要： In a control device, the scan control unit controls a scanning operation in which data is to be generated by reading a document. The data format selecting unit selects one of a first format or a second format different from the first format as a data format in which the data is to be generated. The resolution setting unit sets a reading resolution based on the data format. The resolution setting unit sets a first resolution as the reading resolution when the data format selecting unit selects the first format whereas the resolution setting unit sets a second resolution different from the first resolution as the reading resolution when the data format selecting unit selects the second format. The scan control unit controls the scanning operation to read the document in the reading resolution set by the resolution setting unit.

摘要： A plurality of the light emitting device array units are arranged along a main scan direction in a staggered manner. In a density transformation mode, a transformation pattern is used to transform image data for each matrix of n by n pixels. A rate of writing an image in a sub-scan direction is multiplied by m, and a pixel density of image data written on a photosensitive body is multiplied by (2B+1)/2 in the main scan direction, and multiplied by m(2B+1)/2 in the sub-scan direction. A transformation pattern which is selected according to a position along the main scan direction at which an image is written with respect to a position of each of the plurality of light emitting device array units is used to transform image data.

摘要： A control unit inputs a control signal depending on whether reading at a high resolution is selected or reading at a low resolution is selected in an image reading unit. A first delay circuit and a second delay circuit output image data that is captured by a first CCD line sensor and a second CCD line sensor to an adder after retaining the image data for a time in accordance with the input control signal. The adder generates color image data by adding the image data that is captured by the first CCD line sensor to the image data that is captured by the second CCD line sensor.
