Abstract: An image reading apparatus includes a reading unit, a control unit, and a pattern region. The reading unit moves a linear reading range, which is provided in a main scanning direction, in a sub-scanning direction that intersects with the main scanning direction while reading an object that faces the reading range, and generates image data on the basis of a read result. The control unit controls the reading unit. The pattern region includes a predetermined pattern that defines a reference position for specifying a reading position that is read by the reading unit. The predetermined pattern has a characteristic portion that specifies a schematic position of the predetermined pattern in the sub-scanning direction. The control unit includes a first image acquisition unit, a pattern searching unit, a second image acquisition unit, a characteristic portion searching unit, a first reprocessing instruction unit, and a second reprocessing instruction unit. The first image acquisition unit instructs the reading unit to perform reading and then acquires first image data. The pattern searching unit searches an image of the predetermined pattern in the first image data. The second image acquisition unit, when an image of the predetermined pattern has not been detected by the pattern searching unit, instructs the reading unit to perform reading, and then acquires second image data. The characteristic portion searching unit searches an image of the characteristic portion in the second image data. The first reprocessing instruction unit, when the image of the characteristic portion has been detected by the characteristic portion searching unit, specifies a schematic position of the pattern region in the sub-scanning direction on the basis of a position of the detected image of the characteristic portion, and instructs the first image acquisition unit to perform reading again at the schematic position of the pattern region. The second reprocessing instruction unit, when the image of the predetermined pattern has not been detected again from first image data that are generated through second-time reading by the first image acquisition unit, instructs the second image acquisition unit to perform reading again at a position that does not include the position at which the image of the characteristic portion has been detected.

Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter. After receiving the synchronously processed pixel value from the AND gate, the counter calculates and outputs the extracted row of pixels, including the amount of pixels and the geometric patterns in the row of pixels.

Abstract: An electronic device controller includes an image sensor controller that controls an image sensor having an effective pixel region and a dummy pixel region, and a servo controller that performs servo control on a drive device that drives a carriage on which the image sensor is mounted. The servo controller performs the servo control based on servo control information (for speed control, initial position detection) read by some or all of the dummy pixel region of the image sensor. Alternatively, the servo control may be performed based on servo control information read by one or more separate sensors mounted on the carriage with the image sensor. Moreover, speed servo control may be performed according to speed control ranges based on servo control information for each speed range.
