  • Publication number: 20110281069
    Abstract: A glass substrate obtained by a method including measuring flatness of a glass substrate surface and measuring concentration distribution of dopant in the substrate. Processing conditions of the surface are set up for each site of the substrate based on results from the measuring the flatness and the measuring the distribution, and the finishing is carried out while keeping an angle formed by normal line of the substrate and incident beam onto the surface at from 30 to 89°. The surface is subjected to second finishing for improving an RMS in a high spatial frequency region. The surface after the second finishing satisfies the requirements: an RMS slope in the region that 5 ?m<? (spatial wavelength)<1 mm is not more than 0.5 mRad and an RMS slope in the region that 250 nm<? (spatial wavelength)<5 ?m is not more than 0.6 mRad.

  • Publication number: 20110216967
    Abstract: A specified color area demarcation circuit 6 has a luminance information (histogram) acquisition unit 3 for multiple pixels and a luminance information (histogram) analysis unit 5 for the multiple pixels. The luminance information (histogram) acquisition unit 3 for the multiple pixels acquires luminance information of the multiple pixels in an input image. In order to acquire the luminance information of the multiple pixels, the luminance information (histogram) acquisition unit 3 creates, for example, a histogram of the luminance indicating frequencies. As an example of the histogram, 0 to 255 gray levels in an image are divided into thirty-two (0-7, 8-15, . . . 240-247, 247-255) ranges, and the number of pixels present in each of the divided gray levels (luminance Y) is counted.

  • Publication number: 20110115982
    Abstract: In an X-Y conversion chart, a threshold Th is defined as Y=0, that is, the threshold Th is defined on the X axis, a range from ?Th to +Th is defined as a range in which smoothing (noise elimination) processing is performed, and a range outside the range from ?Th to +Th is defined as a range in which sharpening processing is performed. As shown in equations in drawings, among equations denoted by Y1 and Y2 which are expressed by two linear straight lines, intersections of both the equations Y1 and Y2 are set to the maximum value and the minimum value of an X-Y conversion equation in this case. In addition, the threshold is expressed by an intersection of Y2 and the X axis. This conversion algorithm is formed by only three factors of: a coefficient ? indicating the strength of smoothing; a coefficient ? indicating the strength of sharpening; and a threshold Th on the X axis for determining switching between the smoothing processing and the sharpening processing.

  • Patent number: 7923738
    Abstract: An array of LEDs are grown by epitaxy on row-connecting conductor strips extending in parallel spaced relationship to one another on the surface of a semiconductor substrate and are thereby electrically interconnected in rows. The row-connecting conductor strips are formed by ion implantation of a p-type dopant into parts of an n-type silicon substrate. Column-connecting conductor strips extend over the light-emitting surfaces of the LEDs for electrically interconnecting them in columns. The LEDs are lit up individually by voltage application between one of the row-connecting conductor strips and one of the column-connecting conductor strips.

  • Publication number: 20110080524
    Abstract: Shown is a diagram showing input-output characteristics for color adjustment. The horizontal axis represents an input, and the vertical axis represents an output. In this color adjustment technique, first, so as to prevent degradation the luminance of white after white correction, correction coefficients are determined so that the smallest value thereof may be 1. Note that “1” here is not a strict value. To be more specific, in contrast to the conventional technique in which correction is performed with the largest value being made equal to about “1,” the present embodiments sets the smallest value at about “1.” This idea itself is a first point which makes the embodiments different from the conventional technique. When doing so, all the correction coefficients are “1” or larger. In the case where a correction coefficient is “1” or larger, when the input is large, the output is saturated.

  • Publication number: 20100277500
    Abstract: The fact that B and R are close to a U axis and to a V axis, respectively, is noted. On that basis, from an example of color adjustment parameters set in directions of colors, it is found out that, when inputted V is in a negative range, B has a small influence. Accordingly, a B component is omitted from calculation in order to reduce a calculation amount. Similarly, components having small influences are omitted when B is in a positive range, when U is in the positive range, and when U is in the negative range. Thereby, adjustment parameters AR, AG, and AB set in directions shown in the drawing can be defined. When inputted V is in the positive range, a V component can be adjusted by multiplying AR by the inputted V. Similar processing is performed when inputted V is in the negative range, when U is in the positive range, and when U is the negative range, respectively.

  • Patent number: 7803280
    Abstract: The invention provides a method in which waviness generated on a glass substrate surface during pre-polishing is removed, thereby finishing the glass substrate to have a surface excellent in flatness. The method for finishing a pre-polished glass substrate uses ion beam etching, gas cluster ion beam etching or plasma etching, the method including: a step of measuring flatness of the glass substrate surface using a shape measurement unit, and a step of measuring a concentration distribution of the dopant contained in the glass substrate. Processing conditions of the glass substrate surface are set up for each site of the glass substrate based on the results obtained from the step of measuring flatness and the step of measuring a concentration distribution of the dopant. Finishing includes keeping an angle formed by a normal line of the glass substrate and an incident beam onto the glass substrate at from 30° to 89°.
