20130229404 | IMAGE DATA TRANSMISSION SYSTEM AND ELECTRONIC DEVICE - A transmission unit sequentially outputs a plurality of data signals in a predetermined transmission period during which a one-frame image is transmitted, the predetermined transmission period being defined by a product of a number of the given units and a transmission period of a given unit. Meanwhile, the transmission unit outputs a control signal in the period among the predetermined transmission period that is equivalent to a sum of the transmission time of the given units which does not include the data signals. This period corresponds to the sleep mode period of the transmission unit. The sleep mode period is set such that a ratio of the sleep mode period to the predetermined transmission period is larger than a ratio of a sum of a transmission period of the control signal and a margin period for transmission of the control signal to the predetermined transmission period. | 09-05-2013 |
