    Abstract: The present invention uses a multiple line sensor array (33) for capturing the desired pixels of an object (30). Each sensor is provided with a plurality of photosensitive elements positioned substantially adjacent to each other so as to capture with multiple photosensitive elements the light from one scene pixel area of the scanned media (30). By monitoring the absolute position of the object (30), a feedback signal is generated and used to determine which photosensitive elements are sensing the desired scene pixel area thereby compensating for speed variations in the scanning motion. In another variation of the present invention a weighted average is taken of selected photosensitive elements to obtain a value for the desired scene pixel location. A summation of the signals from the lines of the sensor that are in the correct position multiplied by the correct weighting factor determined by the position sensor feedback will thereby reduce the image degradation caused by varying scanning speeds.

    Abstract translation: 本发明使用多线传感器阵列（33）来捕获物体（30）的期望像素。 每个传感器设置有多个基本上彼此相邻定位的感光元件，以便利用多个感光元件捕获来自扫描介质（30）的一个场景像素区域的光。 通过监视物体（30）的绝对位置，产生反馈信号并用于确定哪些感光元件感测期望的场景像素区域，从而补偿扫描运动中的速度变化。 在本发明的另一变型中，对所选择的光敏元件进行加权平均以获得所需场景像素位置的值。 来自传感器的线的信号与位置传感器反馈确定的正确的加权因子乘以正确的位置，从而减少由扫描速度变化引起的图像劣化。

    Abstract: A pixel clock generator includes a frequency divider 4 that generates a pixel clock PCLK based on a high frequency clock VCLK, a comparator 5 that calculates an error Lerr in the time obtained by integrating a cycle of the pixel clock PCLK for a target number RefN from a time when synchronization signals SPSYNC and EPSYNC are detected, a filter 6, and a frequency calculating unit 7 that sets a frequency dividing value M of the frequency divider 4. The filter 6 and the frequency calculating unit 7 calculate an average of a frequency of the pixel clock PCLK based on the error Lerr, determine a reference error value from the error Lerr in N-cycles, calculate offset values of the frequencies of N pieces of pixel clocks PCLK based on a difference between the reference error value and the error Lerr, and calculate the frequency dividing value M based on a result obtained by adding the circularly selected offset values and the average of the frequency of the pixel clock PCLK.

    Abstract: In a method of electronic recording of information from an information carrier, a position-coding pattern (3) is placed on top of or under the information carrier. The information on the information carrier and the position-coding pattern (3) are imaged with the aid of a plurality of partial images. The position-coding pattern is used to determine where the partial images should be stored in a memory area. The partial images in the memory area together constitute an image of the information on the information carrier. The position-coding pattern is filtered out of the partial images. A product, a device, and software used for implementing the method are also described.

    Abstract: An engraving system (10) and method is disclosed having multiple engraving heads (22, 24) wherein the operation of each head is controllable so that a vertical and/or horizontal screen may be independently controlled, enabling each engraving head to engrave in accordance with different screen rulings selected by a user. The engraving system includes a signal generator for controlling the vertical screen by utilizing a plurality of vertical scalers which use a cylinder factor signal corresponding to the rotational position of a cylinder (16) and as screen variables, such as a screen angle and screen ruling, to generate independent vertically scaled signals which are used to independently energize the engraving heads to engrave patterns defining different vertical resolutions or vertical screens. This system and method also discloses a drive system (28) for independently driving the engraving heads using the cylinder factor signal and the screen variables to enable the engraving heads to engrave patterns having differing horizontal resolution or horizontal screens.

    Abstract: In a process for correcting pyramidal errors due to misinclination of facet surfaces of a rotating polygonal mirror (8) that receives light and is used to deflect a beam of light, wherein a misinclination of a facet surface prompts a corrective deflection of the light beam (5) reflected by the specific facet surface (12), at a correction angle opposite to the deflection by misinclination, the invention provides a continuous check on the orientation of the facet surfaces (16) as they pass a measuring point (15), a measure of the angle of misinclination when it occurs and an adjustment of twice the measure as angle of correction of the corrective deflection. A device for carrying out the process has a light-exposed rotating polygonal mirror (8) as well as a deflection device (9, 10) for corrective deflection of the light beam (5) in the event of a misinclination of facet surfaces and a control device which is used to drive the deflection device. With a measuring device (13) the orientation of each facet surface (16) can be continuously monitored with each pass of the measuring point (15), the angle of misinclination can be determined when it occurs and, as a function thereof, an input signal can be sent to the control device (36).
