  • Patent number: 7649285
    Abstract: A cup-shaped sleeve is made mainly of a resin and has an end where a plurality of pieces of a permanent magnet are insert-molded. An auxiliary ring made mainly of a resin is provided along an inner peripheral surface of the cup-shaped sleeve other than an inner peripheral surface thereof where the permanent magnet is provided. The auxiliary ring has its inner peripheral surface identical to the inner peripheral surface of the permanent magnet or located outside relative to the inner peripheral surface of the permanent magnet. When the cup-shaped sleeve is resin-molded, the resin which is a component of the cup-shaped sleeve is prevented from shrinking inward. Therefore, contact between the resin supporting the permanent magnet and the cylinder is prevented. Accordingly, a linear drive device is obtained in which the reciprocation of the piston is prevented from being hindered.

  • Patent number: 7626601
    Abstract: A video signal processing apparatus for outputting an output video signal to a display unit and displaying an image based on an input video signal on the display unit includes a signal processor for dividing the input video signal into a predetermined number of signals and outputting the signals as the output video signal. The signals as the output video signal drive associated areas obtained by dividing a display-capable area of the display unit. In accordance with the display unit, the predetermined number of signals is set so that the clock frequency of each of the signals output as the output video signal is less than or equal to a clock frequency that can be processed by the display unit.

  • Patent number: 7606415
    Abstract: The invention provides an image processing apparatus and an image processing method. An area to which image data belongs is discriminated, and a correction coefficient to be used for correction of a pixel value of the image data is produced based on a result of the discrimination. Then, the pixel value of the image data is corrected with the correction coefficient. The relationship in magnitude among pixel values in the same area is maintained because the same coefficient is used, but pixel values which belong to different areas can be varied or even reversed. This allows the gradation of an entire image to be corrected while preventing partial deterioration of the contrast.

  • Patent number: 7602440
    Abstract: The present invention relates to an image processing apparatus and method, a recording medium, and a program that can very sharply display video images which are subjected to frame rate conversion by suppressing a decrease in the image quality (blurred images) caused by imaging blur. A high frame converter 11 performs high frame rate conversion on an input moving picture. An imaging blur suppression processor 13 corrects each pixel value forming a subject frame based on at least one value corresponding to the subject frame of the parameter values representing imaging blur detected by an imaging blur characteristic detector 12. Accordingly, a moving picture having a higher rate than that of the input moving picture and having each pixel value suitably corrected to suppress imaging blur is output. The present invention is applicable to a television system.

  • Publication number: 20090213273
    Abstract: A setting information database associates setting information used to output a video signal or an audio signal with a corresponding viewing condition. A setting information registration unit registers setting information and a corresponding viewing condition which have been received by a setting information reception unit so as to store them in the setting information database. An adequacy determination unit determines the adequacy of recommended setting information to be stored in the setting information database. A condition extraction unit extracts pieces of setting information stored in the setting information database on the basis of a viewing condition supplied from an extraction condition reception unit. A recommendable setting derivation unit derives recommendable setting information from the extracted pieces of setting information.

  • Patent number: 7558435
    Abstract: In each of stages of a nonlinear filter, a successively determined target signal and plural adjacent signals are weighted-averaged with plural sets of different coefficients to calculate plural smoothed signals. Differences in level between the target signal and each of adjacent signals and signals arranged within the predetermined interval from the each of the adjacent signals are compared with a threshold value. According to the comparison, flags are set to the adjacent signal, to an adjacent signal arranged at a symmetrical position, and to adjacent signals arranged beyond the adjacent signals. The intervals of adjacent signals are different among stages. The target signal in level is used instead of the adjacent signals with smoothed signals, which are selected according to the flags. Weighting coefficients may be calculated on the basis of the comparison result, and smoothed signals may be synthesized according to the weighting coefficients.

  • Patent number: 7553253
    Abstract: In an automatic transmission (AT) in which an input shaft (Input) and an output gear (Output) are disposed on the same axis and three clutches (C1-C3) and two brakes (B1, B2) are selectively operated to provide six forward speeds, first and second planetary gear sets (GS1, GS2) are configured to consistently reduce the speed of input rotation and output the speed-reduced rotation, thereby enabling downsizing of them. The first and second planetary gear sets (GS1, GS2) are arranged in a transmission case at both the axial ends thereof. Third and fourth planetary gear sets (GS3, GS4) are connected to each other to have four rotation elements in combination, thereby constituting a Simpson planetary gear train. One of the four rotation elements (a fourth carrier (PC4) in an illustrated example) is connected to the output gear (Output).
