Abstract: The present invention provides a method of relocating optical devices onto a carrier substrate in a case where a pixel pitch of a display is not an integer multiple of a pitch of the optical devices arrayed on a sapphire substrate. A moving speed ratio between a donor substrate and a receptor substrate is determined from an array pitch (3, 4) of optical devices (2) formed on the sapphire substrate and an array pitch (5, 7) of optical devices to be transferred onto a carrier substrate (6), and the optical devices are subjected to LIFT (laser transferred) in synchronization with movement of the donor substrate, whereby the optical devices on the sapphire substrate are transferred onto the carrier substrate at an array pitch that is identical to the pixel pitch of the display.

Abstract: Disclosed is an image processing device capable of recognizing a specific image such as an image which is prohibited from printing at high speed and, moreover, without being influenced by an image forming process. A drawing command analysis unit analyzes a drawing command received by a drawing command input unit and sends an analysis result to both an output image data generation unit and a recognition image data generation unit. The output image data generation unit generates output image data adapted to an image formation device in accordance with the drawing command. In parallel with the operation, the recognition image data generation unit generates recognition image data adapted to a recognition unit in accordance with the drawing command. The recognition unit performs a process of recognizing a specific image by using the recognition image data.

Abstract: The present invention provides an image processor and an image processing method wherein a specific image such as an image of which the printing is prohibited can be recognized at high speed and in addition, with high precision. A rendering command analysis unit passes a rendering object to any of a recognition unit for a raster image, a recognition unit for graphics and a recognition unit for a character according to the type of the rendering object in the rendering command and tries to recognize a specific image. The result of recognition by each recognition unit is passed to a recognition determination unit and it is synthetically determined based upon these results of recognition whether the specific image exists or not. Even if the specific image is formed by dividing into plural types of rendering objects, the specific image can be recognized by such recognition processing.

Abstract: A method and apparatus for controlling the phase of a system clock, in which one of a first clock signal and a second clock signal is selected and output to a system as a system clock signal, the first clock signal being generated by a frequency synthesizer synchronized with an external clock signal supplied from a reference clock signal oscillator provided externally of the system, and the second clock signal being supplied from another reference clock signal oscillator provided internally of the system, and the phases of the first and second clock signals are controlled, prior to switching between the first and second clock signals and supplying the switched clock signal to the system as the system clock signal. The switching is delayed for a period while there is a phase shift between the first and second clock signal , when the system clock signal is switched between the first and second clock signal.

Abstract: There are provided a plurality of light sources emitting different color lights, and switch means for selectively lighting either one or all of the light sources. The lights reflected by a multicolor manuscript are converted into electric outputs by an image sensor. The output of the image sensor of the portion of the manuscript having the same color as the lighted light source is caused to exceed a predetermined binarizing level, whereby that portion of the manuscript is prevented from being read.

The color image is read by detecting colors on the scanned portions of the color image on the basis of levels of the light reflected from the color image.

Abstract: A shading correction device has a variable attenuator which is provided in the transmission line of the picture signal after photoelectric conversion by the original reader. For example, at the time of reading all white surface of the original at the beginning of the original scan the information level of each bit of the picture signal, i.e., the level of each picture element, is sequentially attenuated by the variable attenuator. In order to make the level of each picture element uniform, a data on how much attenuation is required, is generated for each picture element and loaded in a memory. The variable attenuator is adapted to be driven and controlled based on the data loaded in the memory at the time of reading the original in the subsequent scan.

Abstract: In a method of controlling the sub-scanning of a document reading apparatus the speed, acceleration or deceleration of the reading section is controlled according to the amount of information stored in a buffer memory which temporarily stores information read by the reading section. The values of the movement speeds, accelerations and decelerations are predetermined according to the stored information amount of the buffer memory and at the time of controlling the reading section, one of these values is selected according to the currently stored information amount of the buffer memory. Whereby any vibration in a reading section is prevented to eliminate the irregularity in the sub-scanning of the reading section.
