  • Patent number: 11922649
    Abstract: It provides the measurement data of each portion of the target object with a high accuracy. The measurement data calculation apparatus 1020 includes an obtaining unit 1024A, an extraction unit 1024B, a conversion unit 1024C, and a calculation unit 1024D. The obtaining unit 1024A obtains the image data in which the target object is photographed and the full length data of the target object. The extraction unit 1024B extracts the shape data indicating the shape of the target object from the image data. The conversion unit 1024C converts and silhouettes the shape data based on the full length data. The calculation unit 1024D uses the shape data converted by the conversion unit 1024C to calculate the measurement data of each portion of the target object.

  • Patent number: 8951353
    Abstract: A manufacturing method for semiconductor device includes: loading a wafer to a reaction chamber and placing the wafer on a support member; supplying process gas including source gas to a surface of the wafer, controlling a heater output and heating the wafer to a predetermined temperature while rotating the wafer at a first rotational speed, and thereby forming a film on a surface of the wafer; stopping supplying the source gas; decreasing a rotational speed of the wafer to a second rotational speed which enables an offset balance of the wafer to be maintained and stopping the heater output; and decreasing a temperature of the wafer while rotating the wafer at the second rotational speed.

  • Patent number: 8804219
    Abstract: An image processing apparatus is disclosed. The image processing apparatus includes a color conversion processing unit which obtains CMY data from input color space coordinate data of image data, and an output data generating unit which generates output data by forming CMYK data by using a result output from a color conversion processing section. The color conversion processing section includes an optimum color reproduction data structure which gives the CMY data for obtaining a full color image optimally reproduced from the input color space coordinate data, and a color material using amount reducing data structure for outputting the input color space coordinate data by reducing the color material using amount with the use of a reference value in which the color material using amount is increased for a hue of an output image giving a high psychological effect and is decreased for a hue of the output image giving a low psychological effect.
