Abstract: There is provided light source device comprising; a plurality of light source sections, a control section, and a light amount monitoring section, wherein the control section gradually increases a voltage value applied to the light source sections from a low voltage value, the light amount monitoring section obtains a voltage value at a time when it is detected that a predetermined illumination light amount has started to be irradiated, and obtains a voltage setting value based on this voltage value, and the control section applies a voltage of this voltage setting value to the plurality of light sources.

Abstract: An illumination apparatus comprises a constant current power supply configured to be capable of supplying a constant current, a plurality of unit circuits each of which includes at least a switching member which is able to shut off a current supplied from the constant current power supply, and a control portion configured to control the plurality of switching members. The plurality of unit circuits is electrically connected to the constant current power supply in a matrix form. A predetermined number of unit circuits in the plurality of unit circuits further have at least one LED which is connected with the switching member in series in each current path which is set when the control portion controls the plurality of switching members.

Abstract: An image display device capable of displaying an images on right and left image display elements (26I, and 26R) by receiving right and left image signals for displaying three-dimensional images which are fed alternately in a field sequence manner. The degree of influence on the viewer is operated by measuring the parallax value of the right and left image signals fed to the right and left image display elements (26L, and 26R) by a 3D protecting means (14), and it is judged whether or not the operated degree of influence reaches a reference value. If the operated degree of influence reaches the reference value, the degree of influence of the 3D image on the viewer is reduced by selectively displaying the result of the judgment on the right and left image display elements (26L, and 26R), so that the image can be viewed in a consistently suitable manner.

Abstract: An autofocus lens barrel has an optical system shifter for shifting a focusing optical system forward and backward in the direction of the optical axis, a driven pulley rotatively driven around the optical axis for actuating the optical system shifter, and a driving pulley which is driven by receiving a driving force. The driving force is transmitted from the driving pulley to the driven pulley by means of a belt. Preferably, an idler pulley should be proved at a position substantially symmetrical to the driving pulley with respect to the optical axis, and the driving force is transmitted from the driving pulley to the driven pulley and the idler pulley by means of a belt.
