摘要:
A temperature detecting unit detects a temperature of an imaging element for imaging an image signal. A storage unit stores phase change of a pulse, which is used by the imaging element when imaging the image signal, involved in temperature change of the imaging element in association with the temperature change. A timing adjustment unit checks temperature information of the imaging element detected by the temperature detecting unit with the phase change stored in the storage unit, and adjusts the phase of the pulse.

摘要:
A transmitter transmits moving image data generated by an image generator to a communication line. A controller judges whether or not the moving image data can be transmitted based on communication status in the communication line. An image analyzer analyzes the moving image data and calculates an information volume thereof when it is judged by the controller that the transmission of the moving image data is not possible, and a storage memory stores the moving image data therein. A transmit image selector selects the moving image data to be read for transmission from all of the moving image data stored in the storage memory based on the information volume when a result of the judgment by the controller shows that non-transmittable status is changed to transmittable status and transmits the selected moving image data to the transmitter.
摘要:
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). As a result, data streams which should be simultaneously reproduced can be easily sorted and multiplexed even when smaller-size buffers are employed.
摘要:
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.
