  • Patent number: 10805481
    Abstract: In an image processing apparatus, in a case where setting values indicate to create scan data by using digital halftoning and requires execution of a prescribed process using a result of character recognition, a controller outputs an instruction to create multiple-value scan data having a pixel value represented by two or more bits. The controller executes the character recognition on the multiple-value scan data. The controller converts the multiple-value scan data into converted scan data by using digital halftoning, and executes the prescribed process on the converted scan data. In a case where the setting values indicate to create scan data by using a method different from the digital halftoning, and requires execution of the prescribed process, the controller outputs an instruction to create setting-based scan data. The controller executes the character recognition on the setting-based scan data. The controller executes the prescribed process on the setting-based scan data.

  • Publication number: 20200066500
    Abstract: In time-series data indicating light emission of plasma when plasma processing is carried out on a sample by generating the plasma, an analysis apparatus creates combinations of a plurality of light emission wavelengths of elements and a plurality of time intervals within a plasma processing interval and calculates, for each of the combinations of the wavelengths and the time intervals, a correlation between an average value of light emission intensity and the number of times the plasma processing is carried out on the samples for each of the combinations of the wavelengths and the time intervals that have been created. Thereafter, the data analysis apparatus selects, as a combination of the wavelength and the time interval used to observe or control the plasma processing, a combination of a wavelength of light emitting from a specific element and a specific time interval having a maximum correlation.
