发明名称 Luminous source apparatus, image projecting apparatus and image projection converting apparatus
摘要 Aluminous source apparatus, an image projecting apparatus, and an image projection converting apparatus are provided, so as to prevent a projected image, or an electronic image obtained through electronization of the projected image from intensity variations. A photosensor detecting the light-emission quantity from a light-emission lamp is set up, in order to regulate the current supplied with the light-emission lamp from a power according to a light-quantity detecting signal from the photosensor, so as to make the light-emission quantity from the light-emission lamp constant. Projected light-quantity onto a movie film is regulated and an image obtained from a shooting section becomes an image having a good quality with a little flicker.
