  • Patent number: 8217973
    Abstract: An exposure device includes plural light-emitting elements, a light amount detection unit, a controller, plural holding units and a connection unit. The controller sequentially determines control values of the light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value. The holding units are provided for the light-emitting elements, respectively. Each holding unit holds a control voltage of the controller. When the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plural light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.

    Abstract: A light transmission device transmits an image signal on light to an output device based on a control signal for controlling the image signal. The light transmission device includes a transmitting interface component, a receiving interface component, and a light transmitting medium. The transmitting interface component converts the image signal to a light signal and transmits the light signal. The receiving interface component converts the light signal transmitted from the transmitting interface component to an image signal and transmits the same to the output device. The light transmitting medium connects the transmitting interface component and the receiving interface component. The transmitting interface component includes a combining component, which classifies the image signal to each of plural bit data channels according to a predetermined condition, inserts the control signal into the remaining bits of the bit data channels and then carries out modulation.
