20090008861 | SHEET FEEDING DEVICE - A sheet feeding device includes a feeding unit that feeds a sheet; a rolling member that rolls by having contact with the sheet being fed by the feeding unit; a supporting member that moves along with a behavior of the sheet with supporting the rolling member so that the rolling member rolls in a feeding direction of the sheet at a predetermined position on the sheet; an acceleration measuring unit that measures accelerations acting on the supporting member in three directions; and a detecting unit that detects a feed error of the sheet based on the accelerations measured by the acceleration measuring unit. | 01-08-2009 |
20110228349 | IMAGE READING APPARATUS - An apparatus includes imaging units, each including: a light source to emit light; and an image sensor to pick up an image of a medium to be moved relatively between the imaging units. The light source of one of the imaging units is provided at a position where a direct light is guided to the image sensor of the other imaging unit, and the image sensor of the other imaging unit is configured to pick up an image for image formation when a reflected light emitted from the light source of the other imaging unit and reflected by the medium is guided to the image sensor of the other imaging unit, and to pick up an image for edge detection when the direct light is guided to the image sensor of the other imaging unit, and an edge of the medium is detected based on the image for edge detection. | 09-22-2011 |
20110299136 | OVERHEAD SCANNER DEVICE, IMAGE ACQUIRING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM - An overhead scanner device includes an area sensor, a linear sensor, and a control unit, wherein the control unit includes an area-image acquiring unit that controls the area sensor to successively acquire a plurality of images, a feature-point extracting unit that extracts feature points from the images acquired by the area-image acquiring unit, a velocity-vector computing unit that computes a velocity vector of each of the feature points by comparing the feature points extracted by the feature-point extracting unit between the images, and a read-start determining unit that determines a read start by the linear sensor, based on the velocity vector computed by the velocity-vector computing unit. | 12-08-2011 |
20130194298 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM STORING IMAGE PROCESSING PROGRAM - 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. | 08-01-2013 |
20140160345 | LIGHTING DEVICE AND IMAGE CAPTURING SYSTEM - 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. | 06-12-2014 |
20140160350 | MOUNTING STAND FOR CAPTURING AN IMAGE AND IMAGE CAPTURING SYSTEM - In an image capturing system, a mounting stand 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, and 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 image the medium set on the medium setting surface. The base, the arm, and the top unit are integrally fixed with each other. | 06-12-2014 |
20140168506 | IMAGE CAPTURING SYSTEM - An image capturing system includes a smartphone serving as an imaging unit, and a mounting stand to be disposed on a medium setting surface on which a medium serving as a reading target is set. The mounting stand has a placement surface on which the smartphone is placed at a position allowing the smartphone to image the medium set on the medium setting surface. When generating a starting trigger based on image information of an imaging area in the state where the smartphone is placed on the mounting stand, the smartphone executes a function (scanning operation) associated with the starting trigger. | 06-19-2014 |
20150092253 | IMAGE READING APPARATUS - An image reading apparatus includes a casing that blocks ambient light and has an opening portion in a bottom surface, an image capturing unit that captures an image of a medium exposed to an internal portion of the casing in the opening portion, and a plurality of light sources that are arranged on the internal portion of the casing and irradiate light toward the opening portion. The plurality of light sources irradiate light to different areas on a plane in the opening portion. | 04-02-2015 |
