Abstract
Abstract The image sensing system includes an image sensing part (1) for sensing an image by means of an image sensor having an existing 4:3 aspect ratio and outputting a video signal; a character generating part (2) for generating a character signal; a combining part (3) for combining the video signal outputted from the image sensing part (1) with the character signal generated by the character generating part (2); an anamorphic lens (4) detachably attached to the image sensing part (1) for varying the aspect ratio of a photographed image by optically compressing the photographed image in the horizontal direction thereof; a detecting part (5) for detecting whether the anamorphic lens (4) has been attached or detached, as well as the characteristic of the anamorphic lens (4) and a control part (6) for controlling the character generating part (2). A video tape recorder (8) records the video signal outputted from the combining part (3) and a ID information associated with the anamorphic lens (4) in accordance with the output of the detecting part (5) and outputted from the ID generating part (7). Each of signal processing parts (9) and (10) performs the processing required to visually display a signal outputted from the VTR part (8). A display (11) has a display screen having an aspect ratio of 4:3, while a display (12) has a display screen having an aspect ratio of 16:9.
