Abstract

The digital image recording device includes a tri-linear array of photosensing elements which include a plurality of photosensor pixels. The tri-linear array of photosensing elements is mounted upon a frame for linear movement within a universal housing. The housing is adapted for insertion into the cartridge film slot of a standard view camera. The movement of the array of photosensing elements across an image plane within the standard view camera sequentially senses an image to be recorded. Each row of the tri-linear array of photosensing elements includes a separate color filter stripe which enables the color recording of an image during one pass of the scanner across the image plane. The array of photosensing elements is connected to a storage and processing unit by an electrical cable which permits communication therebetween. The storage and processing unit performs mathematical calculations to the electrically generated signals received from the tri-linear array of photosensing elements or image data primarily to correct for non-uniformities among the photosensing elements or in general to realign received signal information. Image realignment is then performed by a host computer electrically coupled to the storage and processing unit during the retrieval of image data from the camera. The storage and processing unit may be connected to a host computer having a view screen. The view screen and host computer enable a photographer to visualize and adjust an image to be recorded.

Claims
