PURPOSE:To validly display a picture at a high-vision television or the like by providing a rotary asymmetrical refracted face in an objective lens, and transforming an image by a signal processing means. CONSTITUTION:This device is equipped with an objective lens 2 which forms the image of an object, solid image pickup element 1 which receives the image from the objective lens 2, signal processing means (sampling circuit 3, hold circuit 4, and video signal preparing circuit 5) which prepares an output signal from the image pickup element 1, and a display means (television monitor 6 and long sideway display part 7) which displays the image of the object from a video signal. Then, the objective lens 2 having the rotary asymmetrical refracted face expressed by an expression I, projects the transformed image of the object on the solid image pickup element 1, and the signal processing means 3-5 further transforms the transformed image, and displays it. In the expression I, (x)-(z) are the coordinate values of (x), (y) and (z) coordinates at the time of defining an optical axial direction as an (x)-axis, and the vertex of the screen as an origin. Therefore, the long sideway display part of the television monitor of the television with the high fidelity can be validly utilized.
