  • Publication number: 20070103570
    Abstract: A horizontal direction component pixel extractor extracts a pixel of interest and a horizontal direction component pixel thereof from an input video signal. A vertical direction component pixel extractor extracts the pixel of interest and a vertical direction component pixel thereof from the input video signal. A threshold setter sets a threshold value from the pixel of interest and the vertical processing direction component pixel thereof. A non-linear smoother non-linearly smoothes the pixel of interest using a horizontal processing direction component pixel in accordance with the set threshold value, thereby generating a video signal. A flat rate calculator calculates a flat rate in a vertical direction of the pixel of interest using a vertical processing direction component pixel. A mixer mixes the input video signal and the generated video signal using the flat rate, thereby outputting a horizontal direction smoothed video signal.

  • Publication number: 20070070221
    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: 20070060439
    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).

  • Publication number: 20070047034
    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: 7127122
    Abstract: By the use of an epsilon filter, in the case where a plurality of different illuminations exist, a boundary between the illuminations can be appropriately extracted, and an unnatural image pattern can be prevented from being generated, therefore subjectively preferable compression of a dynamic range can be achieved. An edge strength G(x, y) is calculated per position on an input image, and a threshold E(x, y) of an epsilon filter (12) is controlled on the basis of the edge strength G(x, y). The epsilon filter (12) filters the input image on the basis of the controlled threshold E(x, y). On the basis of the edge strength G(x, y), the threshold E of the epsilon filter (12) is adaptively changed according to a local gradient of a pixel value I(x, y), so in the case of using a linear lowpass filter or a fixed threshold epsilon filter, an illumination boundary can be more accurately extracted.

  • Publication number: 20060215927
    Abstract: The present invention relates to a signal processing apparatus and a method, a recording medium, and a program, in which portions except an edge can be smoothed while the edge whose change in pixel value is steep is held correctly. A pixel of attention is determined in step S11, and a neighbouring pixel is determined in step S12. In step S13, a difference in pixel values between the pixel of attention and each neighbouring pixel is calculated. In step S14, according to a relationship in size between the difference and a threshold value ?., flags are raised for the neighbouring pixel and a neighbouring pixel which are symmetrical. Furthermore, a flag is also raised for a neighbouring pixel away from, in view of the pixel of attention, the symmetrical neighbouring pixel for which the flag is raised. In step S15, 7-pixel taps centered around the pixel of attention are averaged by weight.

  • Publication number: 20060211821
    Abstract: The present invention provides a solution to a problem that a composition including a reactive silicon group-containing polyether undergoes red coloration. More specifically, in a reactive silicon group-containing organic polymer which contains Co, the problem concerned is solved by limiting the Co content to 0.5 ppm or less. As the reactive silicon group-containing organic polymer, for example, a reactive silicon group-containing polyether (A) or a mixture of the reactive silicon group-containing polyether (A) and a vinyl polymer (B) may be cited. The reactive silicon group-containing polyether (A) is obtained, for example, by reacting a polyether or a derivative thereof which contains Co in a content of 0.5 ppm or less with a silane compound which has a group capable of reacting with the polyether or the derivative thereof and has a hydrolyzable group.
