Abstract
A digital camera enables high-speed zooming operation without use of a zoom lens. Light originating from a fixed-focal-length lens is split into two beams by a beam splitter, to thus form respective images on a first image sensor and a second image sensor. The first image sensor and the second image sensor are equal to each other in terms of the number of pixels, but differ from each other in terms of a pixel size. The first image sensor acquires a wide image, and the second image sensor acquires a telephotography image. An output is produced by means of switching between the first image sensor and the second image sensor, in response to zooming operation. When the image from the first image sensor is recorded, focus detection is performed by use of an image signal from the second image sensor, to thus effect automatic focusing.
