<p>In a TV camera main body, a still-image-luminous-flux-decomposing prism is disposed adjacent to a color-decomposing prism of a TV-image-capturing system, whereby still images whose aberration is favorably corrected as with TV images are obtained in a simple and compact configuration. A mechanical shutter is disposed in an optical path of the still-image-capturing system, so as to prevent image blurring and smear from occurring due to temporal shifts between field images. A four-block color-decomposing prism 11A, in which each glass prism has a form identical to a color-decomposing prism of a dual green type, is constituted by a still-image-capturing prism 2d, and a TV-image-capturing three-color-decomposing prism system comprising a prism for blue 2a, a prism for red 2b, and a prism for green 2c. A mechanical shutter 34 is disposed between the light exit end face 7d of the still-image-capturing prism 2d and its cover glass 6d. <IMAGE></p> |
