  • Patent number: 8217977
    Abstract: A color image forming apparatus and a control method thereof to correct an error between scanning lines due to an alignment error between the laser scanning units corresponding with each color of the image forming apparatus on the basis of a difference of detection times between termination signals for each color when the scanning units output a horizontal synchronization signal and a termination signal to scan a line. A difference of termination times between termination detecting sensors may be used to variably set video clocks for each color, thus reducing the number of components required and reducing the signal processing load. A single sensor may be used to detect the synchronization and termination signals, thus further reducing manufacturing costs.

  • Patent number: 8139096
    Abstract: A multi-color image forming apparatus includes signal detecting units which are included in development units and detect horizontal synchronization signals, a correction unit to count pulse widths of the horizontal synchronization signals detected by the signal detecting units and correct timings of vertical offsets to be increased or decreased according to lengths of the pulse widths, and a video controller to output video data to scan multi-color images on surfaces of photosensitive drums according to the timings of the vertical offsets corrected by the correction unit. Even when any one of the laser scanning units and the development units is shifted from a reference position, the vertical offset is corrected such that the multi-color images printed on a recording medium are aligned in a vertical direction. Accordingly, preventing quality of the multi-color images from deteriorating is possible.

  • Patent number: 7694122
    Abstract: An electronic device and a booting method thereof are provided, wherein the method includes the steps of copying the boot image from the first non-volatile memory to the internal RAM when a booting operation of the electronic device begins, setting a stack pointer in the internal RAM by executing a control code to set the stack pointer among control codes of the boot image, and activating the main memory by executing a control code to initialize the main memory controller and activate the main memory among the control codes of the boot image, the control code to initialize the main memory controller and activate the main memory using the stack pointer. Accordingly, since the control code to initialize the main memory controller to activate the main memory is written in a high-level programming language instead of assembly language, the display device can be driven before the main memory is activated.

  • Patent number: 7536498
    Abstract: A method and apparatus for address mapping are provided, wherein the method sets a first address region that is accessible by a processor when a system is booted and a second address region that is expanded by a virtual address, respectively. The first and second address regions are then mapped so that a first physical address region corresponding to a predetermined part of the first address region and a second physical address region corresponding to a predetermined part of the second address region access the same address region. Accordingly, embodiments of the present invention do not require consideration of reallocation of physical address during programming, and the decoding process for address mapping is simplified.
