Patent number: 11875547Abstract: An image processing apparatus according to an embodiment includes a processor. The processor acquires a classification result of classifying each of a plurality of regions set in a processing target image into one of a plurality of predetermined classes. The processor converts multidimensional data corresponding to each of the plurality of regions set in the image into low-dimensional data. The processor causes a display image including one or more regions to be displayed together with a plotted diagram including a plurality of plot points having different colors or patterns applied according to the classification result to the low-dimensional data in each of the plurality of regions, and in a case where an instruction for selecting a selected point from among the plot points is issued, the processor performs a discriminative display causing the selected point and a region corresponding to the selected point in the display image to be visually identifiable.Type: GrantFiled: May 3, 2021Date of Patent: January 16, 2024Assignees: Kabushiki Kaisha Toshiba, Toshiba Digital Solutions CorporationInventors: Yeonsoo Yang, Tamotsu Sato, Hiroyuki Mizutani

Patent number: 11722289Abstract: In a case where signals branched from a single reference signal source are transmitted via a plurality of cables, a phase synchronization circuit can be used to stabilize a phase of a signal to be outputted from each cable. However, the phases of signal to be outputted from each cable is affected by combination of a length of each cable and an amount of delay caused by feedback control, so that phases of synchronization signals to be outputted from a plurality of transmission paths are not always the same as each other. In the present invention, since a frequency multiplier that multiplies a frequency of a signal outputted from each transmission path by an even number is provided for a phase synchronization circuit, the phases of the synchronization signals to be outputted from the transmission paths are aligned even when signals are branched from one reference signal.Type: GrantFiled: March 31, 2022Date of Patent: August 8, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Hiroyuki Mizutani, Sho Ikeda, Kae Morita
