摘要： An aperture stop 10A includes a filter area 1 formed on a flat-plate substrate 23, and an aperture area 2 formed inside the filter area 1. The filter area 1 transmits infrared light and reduces or blocks the transmission of visible light. The aperture area 2 transmits light in the wavelength range corresponding to fluorescent light from an observed area of a subject and light in the wavelength range corresponding to illumination light to the subject. The aperture stop 10A does not reduce the light in the wavelength range corresponding to fluorescent light from the observed area of the subject, but variably reduces visible light since the area of the aperture area 2 is variable. Therefore, it becomes possible to simultaneously and clearly observe, with a simple method, a subject image formed by illumination light in the visible light band and an observed image formed by weak fluorescent light from the observed area of the subject in the infrared light band.

摘要： A zoom lens device includes a focusing lens group arranged on an object side, and a variator lens group next thereto, and a temperature sensor. The focusing lens group includes a focusing lens, and a temperature-based correction lens for correcting changes in focal point caused by temperature changes around the focusing lens group. The temperature-based correction lens is moved by a temperature-based correction lens driving mechanism along an optical axis to a position determined by a temperature detected by the temperature sensor, independently of the positions of the focusing lens or variator lens group. Thereby, the zoom lens device is capable of favorably correcting defocus of the lens group caused by an ambient temperature change with a simple correcting mechanism.

摘要： A video camera system comprises a lens block and a camera block which are attachable and detachable through a block coupling mechanism to and from each other. The detachable lens block incorporates a focus lens drive mechanism for driving a focus lens and an autofocus control section for executing autofocus control. The autofocus control section receives a composite video signal obtained by processing a video signal from an image pickup device in a signal processing section of the camera block. The autofocus control section produces a focus control signal on the basis of the composite video signal to control the focus lens drive mechanism for the execution of the autofocus control. In addition, the detachable lens block is composed of an iris drive mechanism for optically adjusting an aperture of a lens and an autoiris control section for automatically controlling the iris drive mechanism, so that automatic iris control is executed on the basis of the composite video signal outputted from the camera block. This video camera system can decrease the number of connecting lines to be provided between the detachable lens block and the camera block.
