  • Patent number: 7551299
    Abstract: A printing system operates multiple different printing pipeline stages that together convert raster formatted print data or image formatted print data into a printer swath. The raster formatted print data or image formatted print data is received at the different printing pipeline stages according to the print data's level of rasterization. This allows the rasterization stages that have already been performed on the print data to be skipped. In another aspect of the printing system, the controller identifies job or page settings in the raster or image print data and uses the identified job setting in the different pipeline stages to rasterize the print data.

  • Patent number: 7551037
    Abstract: The PLL circuit of the present invention includes a voltage-controlled oscillator, a loop filter, and a charge pump which controls a voltage of the loop filter while the voltage-controlled oscillator is not oscillating. Therefore, it is possible, even while the voltage-controlled oscillator is not oscillating, to control a voltage for the charge pump so that it is equal to a voltage when the voltage-controlled oscillator is oscillating at a predetermined frequency. Accordingly, by the loop filter outputting a voltage signal to the voltage-controlled oscillator when the PLL circuit is turned on, the pull-in time can be shortened.

  • Publication number: 20090157254
    Abstract: A steerable vehicle information display system is provided, in which images remain undisturbed even if a momentary power interruption occurs. The steerable vehicle information display system comprises: a DPF controller (21), which acquires status information (D1 to D4) from the ECUs of each section of a motor vehicle with a predetermined periodicity; a rendering controller (22), which generates component images representative of the status of each section of the motor vehicle based on the status information (D1 to D4) and generates a composite image of a motor vehicle dashboard by compositing the generated component images; and a nonvolatile memory (24), which stores the status information (D1 to D4) or intermediate information generated from the status information, with the information being at least the latest information.

  • Publication number: 20090153446
    Abstract: A driving circuit of display device includes digital/current converting (DCC) circuits one for each data line. The DCC circuit operates to charge a capacitor with a reference current according to a supplied signal from a shift register. The DCC circuit stores a current value of the reference current and outputs it to a data line via a switching element that has been turned on by a digital image data signal (H) of a single line supplied from a line latch. The output value of each DCC circuit is reset one after another in every select scan period in which an OFF signal is sent to all the data lines. In this way, the reset of the output value and the output of the image data signal can be successively carried out within one frame period, enabling the data to be applied to the pixel circuit with the DCC circuits provided one for each data line. This simplifies the driving circuit that drives the pixel circuits provided with an electro-optic element and disposed in a matrix.

  • Publication number: 20090154140
    Abstract: An illuminating apparatus for a displaying apparatus has a clearance C provided between an end edge of a reflective sheet and a base part of a rubber holder which is located on the outer edge of the reflective sheet and closely fixed to the bottom plate part. In addition, the clearance C is set between the hole edge of the mounting hole and the supporting base part of the lamp clip, around the mounting hole. Therefore, expansion deformation of the reflective sheet in the sheet surface direction due to thermal expansion and variation of dimensions due to mold tolerance can be absorbed by the clearances C. As a result, deflection and curling of the reflective sheet is reliably prevented.

  • Publication number: 20090154307
    Abstract: An optical pickup inspection device 3 sends to an actuator drive circuit 16 a command for changing defocus offset amount to set defocus offset amounts, and calculates jitter values for each of the defocus offset amounts based on a reproduction signal from a reproduction signal generation circuit 14. Then, the device 3 determines a quadric approximating curve of jitter values relative to the defocus offset amounts and calculates a correlation coefficient R2 of the quadric approximating curve and measured values. If the correlation coefficient R2 is lower than a threshold value, the setting of defocus offset amounts and the calculation of jitter values are executed once again, otherwise, a defocus offset amount corresponding to a bottom value of jitter in the quadric approximating curve is determined as an optimum value of the defocus offset amount. Thus, a less-error, high-accuracy optimum value of the defocus offset amount can be obtained.

  • Publication number: 20090153707
    Abstract: A camera module 100 comprises at the bottom of a lens unit 4, a flange unit 43 being extended beyond a contact portion C between the lens unit 4 and a lens holder 3. Debris D produced by contact between the lens holder 3 and the lens unit 4 is collected on the flange unit 43. This can prevent poor imaging caused by the debris D. Therefore, it is possible to provide a simply-configured camera module 100 in which poor imaging due to debris is prevented but miniaturization is not hindered.
