摘要:
A communication device includes a communication unit having plural function operation units performing communication with an external device at plural prescribed communication speeds, and a control unit allowing the communication unit to receive a given kind of content data from the external device, estimating an optimum prescribed communication speed in which the power consumption amount becomes smallest from the plural prescribed communication speeds based on a bit rate of the content data, selecting a given function operation unit from the plural function operation units based on the estimated optimum communication speed, allowing the selected function operation unit to receive the given kind of content data at the estimated prescribed communication speed and controlling power consumption to the function operation units other than the function operation unit selected from the plural function operation units to be less than a fixed value.

A recording apparatus for storing input video and audio data temporarily in a memory, reading out back the video and audio data from the memory and recording the video and audio data into a recording medium wherein a storage-size of the memory is found and video data to be stored in the memory is thinned in accordance with the storage-size so that audio data of a minimum required amount can be stored in the memory to prevent continuity of audio data recorded in the recording medium from becoming unsustainable.

In an apparatus for processing a repeatedly reproduced single field of a color video signal, the phase of a chrominance subcarrier in the color video signal is shifted by 90 degrees at each field period, and the single repeatedly reproduced field of the color video signal is selectively delayed during alternate field periods for a delay time equal to one-half the horizontal scanning period so that the single field, as repeatedly reproduced and selectively delayed in two successive field periods, can function as interlaced fields of a frame while avoiding distrubance of the chrominance subcarrier due to the selective delaying in alternate field periods.

In an electronic camera that comprises image-producing element, a signal processing circuit for processing signals from the image-producing element, a record medium for recording signals from the signal processing circuit, a motor for driving the record medium, flash having a charging circuit, a power supply, and a controller for controlling the camera operation, the power to the motor is interrupted by the controller for the duration of time the charging circuit is being charged. In another embodiment, the power is interrupted to both the motor and the signal processing circuit by the controller for the duration of charging, so that a large charging current is available and the signal processing circuit is prevented from erroneous operation due to source voltage drops.

摘要:
An apparatus on the reception side for receiving a control signal in a wireless fashion is disclosed which achieves significant reduction of the standby power. The apparatus includes a wireless communication section for communicating, when the communication section is in an operation state, with a remote control apparatus to render the apparatus operative. When the wireless communication section is in a standby state, a wake control section receives an operation signal from the remote control apparatus and changes over the state of the wireless communication section from the standby state to the operation state.
摘要:
A recording and/or reproducing apparatus for a recording medium such as an optical disc includes a head, a recording and/or reproduction control unit, an arithmetic operating unit and a display control unit. On the recording medium, management data for controlling recording of data recorded on a data recording area or the operation of recording and/or reproducing recorded data, and address data have been recorded. The head performs recording of data on the recording medium or reading out of recorded data therefrom. The recording and/or reproduction control unit records data on the recording medium discretely by the head, and reads out data discretely recorded on the recording medium as continuous data on the basis of the management data. The arithmetic operating unit arithmetically computes data representative of a reproduction position of data recorded in the data recording area of the recording medium. The display control unit allows the display unit to display the entire recording capacity of the recording area of the recording medium on the basis of the management data read out by the head, and allows the display means to display the reproduction position on the basis of data representative of a position calculated by the arithmetic operating unit.
