  • Publication number: 20040175054
    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: 6753910
    Abstract: The invention provides an image processing apparatus and an image processing method and can be applied to an image information apparatus such as, for example, a television receiver, a video tape recorder, a television camera and a printer so that the gradation can be corrected while effectively preventing a finally obtained image from partial deterioration of the contrast. An area to which each of image data belongs is discriminated with reference to, for example, a low frequency component of a pixel value, and a correction coefficient is produced for the area. Such correction coefficients are smoothed between successive frames, and the pixel values of the image data are corrected with the smoothed correction coefficients.

  • Publication number: 20040080023
    Abstract: A conductive material such as silver is charged in a via hole of an insulative substrate made of low-temperature-sintered ceramic. A lower electrode, a dielectric layer, and an upper electrode are formed in a thin film on the insulative substrate. Thus a thin-film capacitor element is formed in which the capacitance value of the capacitor is specified by the overlapping part of the lower electrode and the upper electrode opposed through the dielectric layer. The dielectric layer is shaped like a ring with the via hole (conductive material) as the center and the part exposed inward from the inner periphery of the dielectric layer is served as a lead section of the lower electrode. The lead section is connected to a ground electrode on the back of the insulative substrate through the conductive material.

  • Patent number: 6724943
    Abstract: A device and a method for image processing make it possible to significantly improve the contrast and the sharpness of the whole image, in comparison with the ordinary. By amplifying the portions other than the edges, while conserving the edges with the pixel values which change abruptly out of input image data, it is possible to enhance and display the portions other than the edges, and so it is possible to significantly improve the contrast and the sharpness of the whole image, in comparison with the ordinary.

  • Publication number: 20030156761
    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: 20030071922
    Abstract: A dot detection section of a dot-interference detection section detects a portion where pixels are arranged as “dark-bright-dark” or “bright-dark-bright” in the horizontal direction, within a Y signal containing dot interference, separated by a YC separation process, and outputs the detection result as dot values to a horizontal array checking section and a vertical array checking section. The horizontal array checking section detects whether or not dot values of a predetermined number of pixels arranged horizontally in such a manner as to contain a subject pixel, have the same value. The vertical array checking section detects whether or not dot values of a predetermined number of pixels arranged vertically in such a manner as to contain a subject pixel, are alternately generated as 1 and 2. An enhancement processing section performs an enhancement process on the Y signal of portions other than the portions where dot interference occurs.

  • Publication number: 20030016306
    Abstract: Each of a plurality of input images is smoothed. A plurality of smoothed images different from each other in the degree of smoothing thus results. Each of first and second synthesizers calculate an edge intensity based on an intermediate synthesized image generated from at least one smoothed image and having a relatively large degree of smoothing and another smoothed image having a relatively small degree of smoothing, and synthesizes the intermediate synthesized image and the smoothed image based on the edge intensity, thereby generating a synthesized smoothed image. A second synthesized smoothed image generated by the second synthesizer is output as a final synthesized smoothed image representing an illumination component, and is then used as a coefficient for converting a pixel value.
