摘要:
In a case in which image data used to form an image on a recording medium in a plurality of scans performed across a recording area of the recording medium is generated, a coefficient determination unit determines assignments of output density for the scans on the basis of density characteristics corresponding to the type of recording medium indicated by a recording-medium signal. Multipliers and binary conversion units generate image data for the scans from input image data on the basis of the assignments of the output density.

A reproducing apparatus for reproducing from a medium on which voice and image signals are mixedly recorded in different areas comprises: a reproducing device to reproduce the signal by accessing each area on the medium; an instructing device to instruct the start of reproduction of the voice signal; and a controller for allowing the reproducing device to access to the area in which the voice signal is recorded in response to an instruction from the instructing device when the area which is accessed by the reproducing device is not the area in which the voice signal is recorded. The reproducing device includes: a reproducing head which is movable on the medium; a voice processor to process the reproduction output of the head as a voice signal; an image processor to process the reproduction output of the head as an image signal; and a control circuit for making either the voice processor or the image processor operative. With this apparatus, even if both of the voice and image signals mixedly recorded on a medium, the voice signal can be easily searched or changed in a short time by simple operations.

A video data transmission arrangement writes video data processed for transmission into a detachable data card. The video data stored in the data card is converted into time-continuous video signals which are processed to enable confirmation of the transmitted video data at the transmitter. Video data can be stored in a video memory and updated at regular time intervals to provide backup and a processor operates to freeze the video data in the video memory upon operation of a freeze switch. The video data stored in the video memory is compressed at each update or when a freeze operation is performed. The compressed video data is stored in a random access memory that is continuously supplied with power from a battery. A compression/expansion circuit reads and expands the compressed video data from the random access memory and delivers the expanded video data to the video memory.
摘要:
A circuit such as a duplexer which isolates a first and second frequency signals respectively directed to and from an antenna terminal. A transmitter filter has a output terminal connected to a connecting point through a first inductor. A receiver filter has an input terminal connected to the connecting point. The connecting point is connected to the antenna terminal, and to ground through a second inductor. In a modified circuit the output terminal of the transmitter filter and the input terminal of the receiver filter are respectively connected to the connecting point through first and second capacitors. In the preferred embodiments the transmitter filter and the receiver filter are mounted to one side of a dielectric plate and the inductor and/or capacitors are formed by electrically conductive step lines and a capacitance patterns formed on the opposite side of the dielectric plate.
