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: A serial scanner apparatus, correction method thereof, and storage medium for performing bi-directional reading with high precision and greatly improving the reading speed. A carriage is first driven in the forward direction, then reversed, and driven in the backward direction. The carriage is accelerated until the speed reaches a predetermined velocity v1. When the predetermined velocity v1 is reached, the carriage is driven at constant speed. In the head portion of the constant-speed driving area, a correction area (reference correction area), having the same distance as that of the correction area for forward driving, is provided. With the use of an area (actual correction area) obtained by adding an area for correction time stored by a controller unit to the reference correction area, read-start timing is adjusted and the bi-directional error is corrected.

Abstract: A printing device reads an image on a printing paper with an image pickup part. It image-processes obtained image data in a control part, and operates the positions of respective register marks (R1 to R4). It operates the quantity of displacement necessary for positioning an image. It obtains an offset count number Co for deciding an image recording starting position from the obtained quantity of displacement. It stores the obtained offset count number Co while obtaining starting position data. Then, dimensional correction data for the image is calculated. The image on the printing paper is first picked up, and the necessary quantity of displacement is calculated. A speed coefficient k is calculated for changing the rotational speed of a plate cylinder. Following this, a correction quantity by a Cd default count number previously set for deciding the image recording starting position is changed. Accordingly, the offset count number Co is calculated again on the basis of the obtained speed variable k. The obtained speed coefficient k and the offset count number Co are stored, and starting position data is obtained from both data.
