  • Patent number: 10674172
    Abstract: A difference detecting unit (130) compares a captured image (811) divided into a plurality of blocks with a last captured image (812) to be compared with the captured image (811), on a block-by-block basis to detect blocks having differences from the last captured image (812), as differential blocks. In addition, a differential block selecting unit (140) selects one or more difference transmission scheduled blocks to be encoded and transmitted, from the differential blocks. In addition, a cyclic block selecting unit (160) selects one or more cyclic transmission scheduled blocks to be encoded and transmitted, from cyclic blocks other than the one or more difference transmission scheduled blocks among the plurality of blocks. A total value of amounts of code used to encode the respective one or more cyclic transmission scheduled blocks is in a range of a lower limit value and an upper limit value.

  • Publication number: 20190225260
    Abstract: There is provided a control device for an electric power steering device, which determines an estimate of a steering angle without using an expensive angle sensor to realize highly accurate steering angle control using the determined estimate of the steering angle. A steering angle calculating section 201 acquires a motor rotation angle ?s (i.e., motor angle ?) output from a rotation sensor and acquires a steering torque Tt output from a torque sensor in a steering angle control mode. The steering angle calculating section 201 determines an estimate ?r of an actual steering angle using the acquired motor angle ? and steering torque Tt to realize highly accurate steering angle control using the determined estimate ?r of the actual steering angle.
