  • Publication number: 20200175317
    Abstract: A medicine inspection device, an image processing device, an image processing method, and a program are provided that appropriately extract identification information even when the positional relationship between a printed character and an engraved mark added to a medicine is not constant. The above problem is solved by an image processing device that performs a process of enhancing a printed character portion of a medicine based on at least one image taken with a surface of the medicine being irradiated with light to generate a printed-character-enhanced image, performs a process of extracting only an engraved mark portion from a three-dimensional shape of the medicine based on at least three images taken with illumination directions of the light to the surface of the medicine different from each other to generate an engraved-mark-extracted image, and generates a difference image between the printed-character-enhanced image and the engraved-mark-extracted image.

  • Patent number: 10649605
    Abstract: A conductive film includes a wiring pattern having the following characteristics. For each spectrum in which spectrum peaks obtained by performing two-dimensional Fourier transform on transmittance image data of the entire image has normalized spectrum intensities equal to or greater than a specified value, an angle is set to oscillate by each unit of a specific angle. Intensity differences, each of which is obtained from a maximum value and a minimum value of the normalized spectrum intensity for each angle, are calculated. One or more clusters of bars, which indicate frequencies of a histogram at an average value or more of the intensity difference in a case where the histogram is a histogram of the intensity differences, are isolated from the other cluster.

  • Patent number: 10475175
    Abstract: A conductive film is provided on the display unit such that the wiring patterns of the two wiring portions overlap with the pixel array patterns of the display unit. A projected wiring pattern, which is obtained when the wiring patterns of the two wiring portions having three-dimensional shapes are projected onto a plane perpendicular to a point of view, includes a regular wiring pattern which has a mesh shape, or an irregular wiring pattern which has mesh shapes and which is formed by making the regular wiring pattern irregular. An indicator of evaluation of moirés, which is caused by interference between a combined wiring pattern formed of the regular wiring pattern and projected pixel array patterns obtained when the pixel array patterns are projected onto the same plane, is equal to or less than an evaluation threshold value.
