Abstract: A method for taking a photograph with a camera having a flash light exposure, a natural light exposure, and an automatic selection where the camera can automatically select the flash or natural light exposure, depending upon photographic conditions. This method comprises the steps of determining distances from the camera to objects in a photographic view, detecting luminances of those objects, and activating the camera for taking a photograph of some of the objects with a flash light exposure and of others of the objects with a natural light exposure when the distances and the luminances of the objects are in a certain condition.

Abstract: The object of the present invention is to provide an image forming apparatus capable of enabling high-speed continuous copy of an same single-color image, wherein the apparatus is incorporated with a shift register between an image reader and a laser beam generated for performing imagewise exposure onto a photoreceptor.
