Large format, digital camera systems (10, 100, 150, 250, 310) expose single detector arrays 20 with multiple lens systems (12, 14, 16, 18) or multiple detector arrays (104, 106, 108, 110, 112, 114, 116, 118, 120, 152, 162, 172, 182, 252, 262, 272, 282, 322, 324) with one or more single lens systems

Large format, digital camera systems (10, 100, 150, 250, 310) expose single detector arrays 20 with multiple lens systems (12, 14, 16, 18) or multiple detector arrays (104, 106, 108, 110, 112, 114, 116, 118, 120, 152, 162, 172, 182, 252, 262, 272, 282, 322, 324) with one or more single lens systems (156, 166, 176, 186) to acquire sub-images of overlapping sub-areas of large area objects. The sub-images are stitched together to form a large format, digital, macro-image (80, 230", 236", 238", 240"), which can be colored. Dampened camera carrier (400) and accelerometer (404) signals with double-rate digital signal processing (306, 308) are used.

The embodiments of the invention in which an exclusive property is claimed are defined as follows: 1. A method of acquiring a large area image of a large area object, comprising: acquiring a plurality of small area electronic images of divers portions of the large area object by: (i) positioning at least three focusing systems with the same focal length in fixed, immovable relation to a two-dimensional array of photosensitive elements in the focal plane of the at least three focusing systems, with the focusing systems being coplanar but not aligned with each other in a straight line, wherein an optic axis of each of the three focusing systems is parallel to the respective optic axes of the other focusing systems; (ii) sequentially focusing at least three overlapping divers portions of the large area object onto the array of photosensitive elements through respective ones of the at least three focusing systems to sequentially expose the array of photosensitive elements to the at least three overlapping divers portions of the large area object; and (iii) reading electronic signals indicative of spatial and radiometric distribution of light from the overlapping divers portions of the large area object out of the photosensitive elements; forming a mosaic of the small area electronic images by merging the small area electronic images together in such a manner that overlapping areas of adjacent small area electronic images register with each other; and converting the mosaic of small area images to the large area image of the large area object. 2. The method of claim 1, wherein sequentially focusing comprises sequentially focusing the at least three focusing systems at a timing such that the respective optic axes of the at least three focusing systems are positioned over a same portion of the large area object when focused. 3. A method of acquiring a large area image of a large area object, comprising: acquiring a plurality of small area electronic images of divers portions of the large area object by: (i) positioning four focusing systems with the same focal length in fixed, immovable relation to a two-dimensional array of photosensitive elements in the focal plane of the four focusing systems and in a coplanar, polygon configuration so that the focusing systems are not aligned with each other in a straight line, wherein an optic axis of each of the four focusing systems is parallel to the respective optic axes of the other focusing systems; (ii) sequentially focusing four overlapping divers portions of the large area object onto the array of photosensitive elements through respective ones of the four focusing systems to sequentially expose the array of photosensitive elements to the four overlapping divers portions of the large area object; and (iii) reading electronic signals indicative of spatial and radiometric distribution of light from the four overlapping divers portions of the large area object out of the photosensitive elements; forming a mosaic of the small area electronic images by merging the small area electronic images together in such a manner that overlapping areas of adjacent small area electronic images register with each other; and converting the mosaic of small area images to the large area image of the large area object. 4. The method of claim 3, wherein sequentially focusing comprises sequentially focusing the four focusing systems at a timing such that the respective optic axes of the at least three focusing systems are positioned over a same portion of the large area object when focused. 5. Camera apparatus comprising: at least three focusing systems, each of which has the same focal length and is positioned to have a focal plane that is coplanar with the focal plane of each of the other focusing systems to focus at least three different, but overlapping small area portions of the large area object onto a two-dimensional array of photosensitive elements positioned in the focal plane of the focusing systems, said at least three focusing systems being coplanar but not aligned in a straight line relation to each other, wherein an optic axis of each of the focusing systems is parallel to the respective optic axes of the other focusing systems; a shutter on each of the focusing systems; and a shutter control system that actuates the respective shutters sequentially to expose the array of photosensitive elements sequentially to the respective different, but overlapping small area portions of the large area object. 6. The camera apparatus of claim 5, including four focusing systems positioned in a polygon configuration. 7. The camera apparatus of claim 5, wherein the shutter control system actuates the respective shutters of the at least three focusing systems at a timing such that the respective optic axes of the at least three focusing systems are positioned over a same portion of the large area object when the respective shutters are actuated.
