  • Patent number: 11496400
    Abstract: A network load balancing apparatus has a data buffer for each communication path of a received packet's transfer destinations, calculates a first hash value using a field value contained in the packet, determines, based on the field value of the packet or the first hash value, a communication path of a transfer destination of the packet subject to external transfer control for transmission to a predetermined external server, determines, based on the first hash value, a communication path of a transfer destination of the packet to be subject to priority control, determines, based on a second hash value based on the first hash value, a communication path of a transfer destination of the packet to be subject to load balancing control, to match a preset load balancing situation of the data buffer, and transmits the packet to a data buffer corresponding to the communication path of the transfer destination.

  • Publication number: 20220270264
    Abstract: An imaging device includes a subject detection unit that detects a subject with respect to an input image. The subject detection unit detects at least two parts within the image and determines a priority part among the detected parts. The subject detection unit performs a region extension process of extending the determined priority part to thereby extend a region from the priority part in a direction of another detected part. In detection of a plurality of parts, a part that cannot be detected is also handled as an extended region of a detection part. Thereby, if a user designates a region erroneously, the imaging device can determine that the user has designated the region when the designated region is included in the extended region.

  • Patent number: 10447928
    Abstract: The present invention has an object to reduce occurrence of a state where a frame image with no visible subject has been generated during generation of a moving image with reduced variation in imaging trajectory. A camera trajectory estimating unit estimates an imaging trajectory during taking of a first moving image, from the first moving image. A camera trajectory correcting unit corrects a trajectory variation in the estimated imaging trajectory. An output image generating unit generates a second moving image corresponding to the corrected imaging trajectory, from the first moving image. Here, the camera trajectory correcting unit sets at least one reference point from the first moving image, and corrects the imaging trajectory so as to cause the reference point in frame images constituting the second moving image to have a position residing within a predetermined range in the frame image.
