Abstract: An image joining method for a scanner that scans and transfers image data to a terminal is provided. During scanning and data transfer, when the image data stored in a register is full, an image processor stops the scanning of a linear photodetector. Meanwhile, a matrix photodetector fetches and stores the image of a code strip. Then, the photodetectors are moved backward a distance larger than that being required to be accelerated forward when the scanner resumes scanning. After the data in the register being transferred and cleared, the linear photodetector resumes scanning at a normal moving speed. The code strip image is further fetched and compared with the stored one to get a joining point of scanned image data. By the joining point, the new and prior image data portions are joined and the scanning proceeds, and joined image data will not be overlapped or broken.

Abstract: The image reading apparatus conveys a reading unit or a document to read the document. Conveyance is implemented by motor control based on a target position trajectory. The reading unit reads the document each time a line start signal is inputted. When a predetermined condition is satisfied, the reading operation is invalidated. A conveyance position at a timing to start the first reading operation invalidated is specified as an interrupted position. The object is arranged at a conveyance restart position moved back from the interrupted position. A target position trajectory is newly set. A conveyance time from the conveyance restart position to the interrupted position defined by the target position trajectory is an integral multiple of an output cycle of the line start signal. The motor control based on the target position trajectory is started at a timing coinciding with an output timing of the line start signal.

Abstract: Disclosed herein is a method of controlling a motor in an image reading apparatus. It may be possible to optimize the drive current of the motor for driving the movement of the scanning module by using information associated with, for example, the time it takes for the scanning module to return to a home or rest position after the scanning module is moved from the home position to a predetermined position. Such optimized drive current can result in improvements in the reading performance of an image by the image reading apparatus and reduction of power consumption.

Abstract: To rotate a transport motor and to stop a carriage motor at an ADF reading angle, a control unit outputs a first and a second signal to a first and a second D/A converter, and a power on/off signal to an A-phase driver circuit for the carriage motor. The D/A converters convert the signal to a first and a second voltage. A transport motor driver supplies power to the transport motor on the basis of the first voltage, and a carriage motor driver turns on and off power supply to the A-phase on the basis of the first voltage and the power on/off signal, and supplies power to a B-phase on the basis of the second voltage.

Abstract: Systems and methods for processing, storing, and viewing extremely large imagery data rapidly produced by a linear-array-based microscope slide scanner are provided. The system receives, processes, and stores imagery data produced by the linear scanner as a series of overlapping image stripes and combines the data into a seamless and contiguous baseline image. The baseline image is logically mapped into a plurality of regions that are individually addressed to facilitate viewing and manipulation of the baseline image. The system enables dynamic imagery data compression while scanning and capturing new image stripes that eliminates the overhead associated with storing uncompressed image stripes. The system also creates intermediate level images, thereby organizing the baseline image into a variable level pyramid structure referred to as a virtual slide. The system facilitates the use of virtual slides in applications such as telemedicine, telepathology, microscopy education, and analysis of high value specimens like tissue arrays.
