  • Patent number: 10348989
    Abstract: The present technology relates to an image processing device, an image processing method, and an image processing system capable of improving detection accuracy of a defective pixel. Provided is an image processing device including a defective pixel estimation unit that estimates a defect of a pixel of interest in an image captured by a solid-state imaging device that contains a two-dimensional array of color pixels, and high-sensitivity pixels having higher sensitivity than sensitivities of the color pixels. The defect of the pixel of interest is estimated on the basis of a correlation between pixel values of the high-sensitivity pixels, and pixel values of the color pixels. The image processing device further includes a defective pixel correction unit that corrects the pixel of interest when it is estimated that the pixel of interest is a defective pixel. The present technology is applicable to an image processing device which corrects a defective pixel by signal processing, for example.

  • Patent number: 7789222
    Abstract: An endless dough conveyor 16 is provided with a resin endless toothed belt 18 instead of a metal chain. A toothed pulley 22 around which the endless toothed belt is wound is also made of resin. A rail 64 is disposed adjacent to a horizontal path of the belt, and a roller 46 attached to the belt is adapted to roll on the rail. At least two induction motors are provided for driving the endless toothed belt. The induction motors are supplied with electric power from a single inverter 35. At least a pulley is provided with a detecting unit 80. The detecting unit 80 detects a state in which teeth of the endless toothed belt climb onto that of the pulley, thereby predicting breakage of the belt. Thus, it is possible to prevent contamination of dough in a proofer.
