Abstract
Abstract An imaging device, such as an electric camera, in which an optical image of an object is converted into a set of image data. The device includes a line sensor and an area sensor. A lens system impinges the optical image onto the line and area sensors, where the first and second data are produced, respectively. At this time, a scanning mechanism moves the line sensor relative to the optical image to scan the optical image. The first and second data is then synthesized into the image data to be output.
