Abstract: An endoscope apparatus includes: first and second cooling units configured to cool first and second light source portions; an image pickup portion configured to generate a picked-up image; and a cooling control portion configured to control amounts of light emission of the light source portions while maintaining an amount-of-light ratio so that the brightness of the picked-up image becomes the target brightness and control cooling based on the information about the amount-of-light ratio and the brightness control information; wherein the cooling control portion decides a cooling capacity of the first cooling units and a cooling capacity of the second cooling units for cooling the respective light source portions for which the amounts of light emission are controlled, at the cooling ratio, so as to cause the light source portions to be included within a predetermined temperature range, based on the brightness control information.

Abstract: The present invention provides a receptacle connector including: a grounding portion configured to ground a connection object; and a ground connection terminal that is configured to be switchably held in a first state in which the ground connection terminal is electrically separated from the grounding portion, or in a second state in which the ground connection terminal is electrically brought into conduction with the grounding portion. The ground connection terminal is switched between the first state and the second state in operative association with interlining of the plug connector and the fitting portion. In the first state, the grounding terminal and the grounding portion are electrically separated. In the second state, the grounding terminal and the grounding portion are electrically brought into conduction with each other through the ground connection terminal.

Abstract: An endoscope system including a control section that controls an LED driving section to supply driving currents to LEDs of a plurality of colors to cause the LEDs to emit lights in a frame-sequential manner and a processor that divides a total exposure period in one frame period of the frame-sequential light emission into ratios of light emission periods for each of the respective colors obtained by dividing light amount ratios of the lights of the plurality of colors, which should be received in a CCD, respectively by respective maximum light emission intensities of the LEDs of the plurality of colors and sets respective maximum light emission periods of the LEDs of the plurality of colors.
