  • Patent number: 11928829
    Abstract: An information processing device acquires an image captured by a transmission electron microscope. The information processing device, for each partial region in the image, executes a two-dimensional Fourier transform on an image of the partial region. The information processing device, based on results obtained by executing the two-dimensional Fourier transform on each of the partial regions, performs clustering of frequency strengths obtained from the results of the two-dimensional Fourier transform. The information processing device determines regions of different crystallinity in the image, based on results of the clustering.

  • Publication number: 20110298904
    Abstract: The frame-parallax-adjustment-amount generating unit outputs, as first parallax data, parallax data of an image portion protruded most among image portions protruded more than a first reference value from a pair of frame images forming a three-dimensional image. The pixel-parallax-adjustment-amount generating unit outputs, as second parallax data, parallax data of an image portion retracted more than a second reference value from the pair of frame images. The adjusted-image generating unit generates a pair of image output data by moving the entire pair of image input data to the inner side based on the first parallax data and moving an image portion retracted more than the second reference value of the pair of image input data based on the second parallax data to adjust a parallax amount and outputs the pair of image output data.

  • Patent number: 4879503
    Abstract: A blower motor control for an air conditioner is carried out so that when a detected actual rotation speed has come into an allowable deviation range to a target rotation speed at the time of controlling the motor so as to approach its rotation speed to the target rotation speed, the output for adjusting the rotation speed is not changed. As a result, a stable rotation speed can be obtained as long as the load on the motor does not fluctuate. Furthermore, after the output has been fixed, the allowable deviation range is expanded to prevent the output from changing even if slight load fluctuation is caused. This allows stable controls.
