  • Patent number: 11839980
    Abstract: An image processing apparatus capable of analyzing a cause of an abnormality of a system efficiently. The image processing apparatus includes a monitoring unit and an analysis unit. The monitoring unit monitors a monitoring object to detect occurrence of an abnormality in the monitoring object by applying an image process to a first area in each of images of the monitoring object that are photographed at different time points. The analysis unit analyzes a cause of an abnormality detected by the monitoring unit by applying an image process to a second area that is different from the first area in an image of a time point preceding a time point at which the abnormality is detected.

  • Patent number: 11800230
    Abstract: An image processing apparatus communicates an image capture device having panning, tilting, and zooming function. A code area is detected by performing a matching process on a whole object image area acquired by photographing an area including a whole predetermined object on which codes are attached, by an image capture device. Grouped areas are generated by grouping detected code areas, based on an angle of view to be set when performing photographing with zooming. The image capture device performs panning, tilting, and zooming operations, such that the generated grouped areas are sequentially photographed at a zoom magnification setting value. An image processing area set with respect to a group image obtained by performing the panning, tilting, and zooming operations and photographing each of the generated grouped area. Information on each code area included in the set image processing area is read.

  • Patent number: 11455481
    Abstract: An image processing apparatus is configured to scan code from a first image captured by a first camera, to acquire a second image captured by a second camera different from the first camera in a case where not all of the code is successfully scanned from the first image, and to scan code from the second image. The image processing apparatus is further configured to compare the code scanned from the first image with the code scanned from the second image, and to acquire a piece of the code scanned from the second image instead of a piece of code scanned from the first image that has not been successfully scanned from the first image in a case where the code scanned from the first image and the code scanned from the second image are at least partially same as a result of comparison.

  • Patent number: 11336831
    Abstract: An image processing device adjusts an imaging direction and an imaging magnification by performing driving control of an imaging device for each image processing process and sets an imaging position of a measurement target. The image processing device calculates an evaluation value of set feature parts in a captured image input at the time of measurement on the basis of captured image data and compares the evaluation value with determination conditions. If the determination condition is satisfied, the image processing device performs predetermined image processing and outputs a result of the image processing to a control device.

  • Publication number: 20170366832
    Abstract: The present invention is directed to a technique capable of preventing resources from being wastefully used due to continuous reproduction of video data which cannot be viewed by a user as the video data does not exist in a display range of a window or preventing the user from missing the video data. A CPU of a video transmission apparatus determines whether a reproduction frame of video data during reproduction is within a display range of a window. As a result of the determination, if the reproduction frame is not within the display range, the reproduction of the video data is stopped and a reproduction position is stored.
