  • Patent number: 9854167
    Abstract: A frame skipping process suited to a scene is achieved by providing an encoder which encodes input image data, an encoding determination unit which compares image movement information with a threshold to determine whether or not encoding is to be performed, a frame skipping controller which performs a frame skipping control if encoding is not to be performed, and a threshold correction unit which corrects the encoding determination threshold based on the result of the encoding process. The image movement information used in the encoding determination unit is any one or a combination of pixel movement information obtained by a representative point matching scheme performed by a pixel movement calculation unit, angular velocity sensor information obtained from a lens controller, and frequency information obtained from an image processor.

  • Patent number: 8624993
    Abstract: An image processor detects an on-screen motion of a photographic subject in video image data generated by an image sensor provided in a camera body and outputs a photographic subject motion information. A sensor detects a motion of the camera body and outputs the detected motion as a camera body motion information. A scene decision encoding controller decides an image pickup condition of the video image data based on the photographic subject motion information and the camera body motion information, and performs an encoding amount regulation control suitable for the decided image pickup condition to an image compression processor.

  • Patent number: 8045018
    Abstract: An imaging processing unit signal-processes main picture data outputted from an imaging device. A zoom processing unit subjects the signal-processed main picture data to picture resize processing. A display picture management unit subjects the signal-processed main picture data to resize processing by the zoom processing unit to generate display picture data, aside from the main picture data recorded onto a recording medium at the time of photographing, and temporarily stores the display picture data in a memory area set inside or outside the integrated circuit. A display picture processing unit subjects the main picture data and the display picture data to display processing.

  • Publication number: 20110181744
    Abstract: When an input image is received from an imaging element, a detection circuit detects frequency information of the input image, and an electronic shake processing circuit detects shake information (motion amount) of the input image. A CPU receives the frequency information and the shake information via an image processing circuit. The CPU increases a compression ratio of the input image when high frequency components are dominant, and decreases the compression ratio when low frequency components are dominant. The CPU also increases the compression ratio when the input image is moving, and decreases the compression ratio when the input image is not moving. A compression/decompression circuit compresses the image based on the compression ratio thus set.

  • Publication number: 20100290536
    Abstract: An image transmission device (101) includes: an encoding section (102) configured to retrieve and encode image data and output encoded data in one frame in predetermined units; a padding section (107) configured to add padding so that the size of data output from the encoding section (102) matches a predetermined size; a packet processing section (103) configured to perform packetization upon completion of padding addition by the padding section (107); and a memory (105) configured to hold encoded data and packet data. An image reception device (201) includes: a depacketizing section (202, 203) configured to receive a packet from the image transmission device (101) and depacketize the packet; and a decoding section (204) configured to decode compressed data in predetermined units and output a stream.

  • Publication number: 20100274918
    Abstract: A comparative time of a first data stream accumulated in a buffer memory is compared with a comparative time of a second data stream (S113). If the comparative time of the first data stream is earlier, the first data stream is multiplexed (S114). On the other hand, if the comparative time of the first data stream is later, the first data stream is not immediately multiplexed. When a data stream is accumulated in a buffer memory, the comparative time of the data stream is a multiplexing reference time indicating the timing of reproduction of the data stream, which is obtained based on time information contained in the data stream or the like (S116). On the other hand, when a data stream is not accumulated in a buffer memory, a multiplexing predicted time which is predicted as the multiplexing reference time of a data stream which is to be next accumulated is used as the comparative time of the data stream (S117).
