An automatic zoom camera and driving method therefor by which a user can take an optimal photograph, while controlling a zoom operation by synthetically controlling a shading of a picture and a change of colour varied in response to a zoom operation in accordance with a distance of an object, sensitivity of a film, environmental brightness and a brightness index of a strobe, while operating a zoom function. The automatic zoom camera is constituted by a switch block to sense information about an automatic zoom mode, a strobe mode, a sensitivity of film and a zoom position. In addition, the camera is able to sense the distance of an object via an infrared-emitting element and a light receiving element; information about an environmental brightness via a photoconductive cell; and a micro controller to minimize changes of colour and shading of a photograph. <IMAGE> |
