  • Patent number: 6507368
    Abstract: This invention is to enable, at low cost, image display with little line flicker based on an interlaced image signal and satisfactory movie display characteristics. The first de-interlace mode in which interlaced scanning line signals in the consecutive odd- and even-numbered fields are received by storage means, and the scanning line signals in the consecutive odd- and even-numbered fields are alternately read out to perform de-interlacing, and the second de-interlace mode in which scanning line signals in the odd- or even-numbered field are read out in units of fields and magnified in the vertical direction to perform de-interlacing are prepared. The scanning line signals are compared between the fields to determine whether the signal is a movie or a still image. When it is determined that the signal is a still image, the signal is displayed on a display device using a non-interlaced signal obtained in the first de-interlace mode.

  • Patent number: 6507369
    Abstract: The present invention relates to a caption data processing apparatus for a digital TV for processing caption data contained in a broadcast signal. In particular, the apparatus is capable of preventing an error occurred when the additional byte of a command or a text overlaps with a code of a Reset command or a DelayCancel command to be looked up, by storing additional byte length of all commands and texts contained in a caption data to a lookup table, further reading the caption data stream as much as the length of a corresponding command using the above values, and storing the data stream to a service input buffer. In addition, the size of the lookup table can be reduced by creating the lookup table according to the regularity of a caption code mapping of a digital TV, and accordingly the time taken in looking up a Reset command and a CancelDelay command can be reduced.

  • Patent number: 6507372
    Abstract: In an image enhancement method and circuit, a luminance signal is extracted from input color signals. Histogram equalization is performed using a cumulative density function of the extracted luminance signal which is input in a screen unit. A transform function is controlled to map a mean level of the extracted luminance signal to itself, so that an adjusted luminance signal is output. The color signals are varied according to the variation of the luminance signals to output compensated color signals. Thus, image contrast is enhanced, and an undistorted color signal is provided at the same time. In order to reduce the hardware of the circuit, an interpolated cumulative density function is obtained by interpolating a quantized cumulative density function of an input luminance image and is used as a transform function. The transform function is controlled to map a mean level of the input luminance image to itself.

  • Patent number: 6507373
    Abstract: In a video stabilizing circuit for a display apparatus, the clamp levels of R, G and B chromatic signals are controlled by feeding back the output currents of respective R, G and B terminals so that real time responses can be made, as against the fluctuations of video output load, thereby obtaining high brightness displays. The circuit according to the present invention is characterized in that output currents of R, G and B terminals are fed back from video output sections to clamp level control sections. The potential of a cut-off control terminal of the video pre-amplifier is then varied in such a manner that, if the beam current sensed by the clamp level control section is large, the bias voltage of the chromatic signals is made small. If the beam current sensed by the clamp level control section is small, the bias voltage of the chromatic signals is made large. Therefore, during a high brightness display, fluctuations in the brightness of the high beams and low beams is reduced and display is improved.

  • Patent number: 6507391
    Abstract: Frequency domain velocity measurements and time domain velocity measurements are made using light from cells or other objects. An optical grating is used to modulate the light from an object so that it has a frequency proportional to the velocity of the object. Depending upon the embodiment, the pitch of the optical grating is uniform or varying. The modulated light is detected, producing an analog signal that is then digitally sampled. Time domain signal processing techniques are used to determine the velocity of the object from the digital samples. Preferably, the velocity measured is applied in determining a timing signal employed for synchronization of an image of the object and an detector signal in an optical analysis system that uses a time delay integration (TDI) detector to determine characteristics of the object in response to light from the object.

  • Patent number: 6507393
    Abstract: A method and an apparatus for detecting removable particulates initially on a test surface or surface to be inspected. The removable particles are transferred to a portion of a tacky surface on a carrier by adhering and then removing the portion of the tacky surface from the test surface. The carrier is received by a positioning means and passed through the field of view of a surface inspection means guided by a controller. Signals from the surface inspection means are combined with coordinates from the controller to produce particle coordinates, which indicate particulates initially on the test surface. Particle coordinates on the tacky surface measured before the tacky surface is adhered and removed from the test surface can be compared with particle coordinates measured after the tacky surface is adhered and removed from the test surface.

  • Patent number: 6507401
    Abstract: A method and apparatus for determining the concentration of a constituent in a fluid by directing a beam of light into the fluid and sensing the intensity of components of the light emerging from the fluid at various wavelengths. The light emerging from the fluid can be light that has been attenuated by absorption or induced by fluorescent radiation. The effect of scattering on the light is minimized by normalizing the component intensities, which are then applied to an algorithm incorporating weighting factors that weighs the influence that the intensity at each wavelength has on the determination of the concentration of the constituent for which the algorithm was developed. The algorithm is developed by a regression analysis based upon a plurality of known mixtures containing various concentrations of the constituent of interest.

  • Patent number: 6507404
    Abstract: An interference optical system (1) is employed to split an input light beam in two, giving a predetermined optical path length difference to the resultant two light beams and thereafter synthesizing them to generate interference fringes. A reference light with a known wavelength &lgr;1 is introduced into the interference optical system (1) from a coherent reference light source (2). A test light with an unknown wavelength &lgr;2 is simultaneously introduced into the interference optical system (1) from a coherent test light source (3) via a different optical path. The interference optical system (1) modulates both received signals obtained from the reference and test lights by giving the same variation to optical path length differences for the reference and test lights. Degrees of modulations of the received signals, obtained from the reference and test lights, depend on their wavelengths &lgr;1 and &lgr;2, respectively.

  • Patent number: 6507411
    Abstract: When an original image is to be printed as a poster composed of an array of 4×4 output images, an image is generated by enlarging the original image fourfold in the vertical and horizontal directions and dividing the enlarged image into 16 parts. These 16 partial images are output successively starting from the upper left or lower right of the 4×4 array, depending upon the designation. If there is a blank page, the blank page is output as is even if the printer possesses a blank-paper economizing function. Thus, when a poster printing function is used, the user designates the manner in which the enlarged image is divided up and the order in which the divided images are printed. Even if the printer is equipped with the blank-paper economizing function, normal printed results can be obtained merely by joining the output sheets together in the order that conforms to the manner in which the enlarged image was divided.
