  • Publication number: 20200397658
    Abstract: A continuous manufacturing system continuously manufactures a product from a powder of a raw material. The system includes a first processing device that performs first processing on the powder of the raw material; a second processing device that performs second processing on the powder on which the first processing device has performed the first processing; and an inspection and sorting device including an inspection chamber into which powder sent from the first processing device flows. When a prescribed amount of the powder has accumulated in the inspection chamber, the inspection and sorting device inspects the powder inside the inspection chamber after blocking a path connecting the first processing device to the inspection chamber. When the inspection ends, the inspection and sorting device removes the blocking after discharging the powder from inside the inspection chamber.

  • Patent number: 10706513
    Abstract: An image signal is subjected to image correction performed by an image correction unit on the basis of retinex processing. The image correction unit performs spectral decomposition for the image signal. A retinex unit performs retinex processing for the image signal subjected to the spectral decomposition, and a spectrum synthesis unit synthesizes the image signal output from the retinex unit. A transformation unit performs transformation from a RGB color space to a HSV color space, and an inverse transformation unit performs transformation from the HSV color space to the RGB color space. The transformation unit transforms an input image signal and outputs the transformed image signal to the spectral decomposition unit. The inverse transformation unit receives the output signal from the spectrum synthesis unit and outputs an image correction signal. Spectral decomposition of the image signal in the spectral decomposition unit is hue-based spectral decomposition in the HSV color space.
