  • Patent number: 7508115
    Abstract: A horn that can suppress oscillation components other than the component in the horizontal direction, a horn unit, and a bonding apparatus using same are provided. The horn has a cross-section variable section in which a cross section perpendicular to the lengthwise direction (X direction) thereof has a first region extending in the Z direction and a pair of second regions sandwiching the first region from Y direction. In the position P3 corresponding to an anti-node of a standing wave of oscillations excited in the horn, a sectional area S1 of the first region assumes a maximum and a sectional area S2 of the second region assumes a minimum. With a transition from the position P3 to the other positions corresponding to nodes, the sectional area S1 decreases and the sectional area S2 increases. As a result, oscillation components other than those in the X direction are suppressed.

  • Patent number: 7372474
    Abstract: An apparatus and a method for flexibly adjusting the contrast of an input image signal. Specifically, a control signal for controlling the contrast of a displayed image is generated responsive to an input image signal, and the luminance signal level of the input image signal is adjusted on the basis of the generated control signal. A display image for demonstration via a liquid crystal display surface is generated on the basis of the adjusted luminance signal level. The illumination brightness on the liquid crystal display surface is controlled in correlation with the adjustment of the luminance signal level on the basis of the generated control signal.

  • Patent number: 7190401
    Abstract: An image processing apparatus and an image processing method permit easy adjustment of luminance and contrast, and also permit easy check of the brightness of a target image. A signal format of an image signal is determined by a determiner circuit, and an image signal of a luminance reference image that provides the standard for determining luminance is generated by a luminance reference signal generator circuit on the basis of a result of the determination. A mixing circuit generates an image signal for displaying a target image combined with a luminance reference image. The signal level of the image signal is adjusted by an adjusting circuit so as to adjust luminance and/or contrast. A discrimination display signal superimposing circuit generates a signal of a luminance identifying image superimposed in a desired luminance area. From the luminance reference image, the brightness at a desired position on an image can be easily checked.

  • Patent number: 5179437
    Abstract: A color correction apparatus for a color television camera, in which color correction is performed while comparing two images obtained from a test chart signal generated from a test chart signal-generating circuit disposed in the interior of a camera device or outside the camera device and a pick-up signal generated by photographing a test chart by a camera device. By arranging circuits for automatizing these functions, color correction based on various data is automatically carried out, and when a special effect is produced by performing color correction of other camera device based on color correction data detected by one camera device, the same color correction can be simultaneously performed in other camera device based on the color correction data of one camera device.
