Abstract
A controller for switching the operation state of a transmitter portion sets a transmitter portion in which the data amount to be transmitted is larger than a predetermined amount to a high speed mode, sets a transmitter portion in which the data amount to be transmitted is below a predetermined amount and larger than zero to a low speed mode, and sets a transmitter portion in which the data amount to be transmitted is equal to zero to a sleep mode. The power consumption in the transmitter portion in which the data amount to be transmitted is small and the transmitter portion in which the data amount to be transmitted is equal to zero can be suppressed and thus the power consumption can be reduced.
Claims6
An interface comprising:
- transmission means of a plurality of channels for transmitting an image signal for displaying an image on an image display device;
- receiving means of a plurality of channels for receiving the image signal transmitted from the transmission means and outputting the image signal to the image display device side;
- and
- operation switching means for switching the operation state of at least one of the transmission means and the receiving means, wherein at least one of the transmission means and the receiving means has a processing mode for subjecting the image signal to predetermined processing, a low speed processing mode for subjecting the image signal to predetermined processing with power lower than the processing mode, and a stop mode for stopping the predetermined processing of the image signal, and the operation switching means sets to the processing mode a channel in which an image signal amount to be processed is larger than a predetermined amount, sets to the low speed processing mode a channel in which the image signal amount to be processed is not more than the predetermined amount and is larger than zero, and sets to the stop mode a channel in which the image signal amount to be processed is equal to zero.
