  • Patent number: 11948026
    Abstract: Formed is a dither pattern that makes it possible to output an image with excellent dot dispersibility and reduced graininess regardless of controls after quantization processing. To this end, an extended pattern in which multiple divided pixels correspond to each of multiple pixels included in quantization data and one or more of the multiple divided pixels are determined as dot-arrangeable-pixels in which dots can be printed is generated. Thereafter, the thresholds of the dither pattern are set based on the extended pattern in which the dots are arranged to obtain predetermined dispersibility.

  • Publication number: 20240086662
    Abstract: An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.

  • Patent number: 11017817
    Abstract: The present invention enables correct placement of an electronic mark on a frame of captured image data intended by a remote control apparatus performing monitoring. Monitoring image data with a time code is transmitted to an external device. A command (an electronic mark placement command, or the like) to which a time code value showing a command target frame in the monitoring image data is added is received from the remote control apparatus. Processing based on the command is performed on a frame corresponding to the time code value added to the command, among image data corresponding to the monitoring image data recorded on a recording medium.

  • Publication number: 20200370200
    Abstract: Provided is a method of manufacturing an oriented steel plate having two or more regions in each of which a crystal orientation is arranged in a specific direction. In the method, at least two single crystal steels are brought into contact with a principal surface of a polycrystalline steel plate so that crystal orientations of the single crystal steels and are arranged in different directions, and heat treatment of the single crystal steels and the polycrystalline steel plate is performed. This causes crystal growth following the crystal orientations of the single crystal steels to occur in the polycrystalline steel plate. Then, two or more single crystal steels having different crystal orientations are formed in the polycrystalline steel plate.

  • Patent number: 10749416
    Abstract: A method is for manufacturing a core plate having an annular core back and teeth extending from the core back toward the center. The core plate is obtained by performing a punching step, a winding step, a straining step and an annealing step. At the straining step, compressive strain is applied to the core back or the band-shaped core back that is to be the core back after winding. At the annealing step, the core back or the band-shaped core back is annealed to be recrystallized after the applying of strain.
