Abstract
Abstract A solid state apparatus for imaging with improved resolution, wherein there can be present at least two solid state sets of detector elements each set of which is sensitive to a different wave length of electromagnetic energy from the other. Each detector is situated such that it may record a picture element which is systematically offset from and partially overlaps the picture elements recorded by the analogous detectors of the other sets. There are existing computer programs for changing the data obtained into a form suitable for an image of better resolution than is possible when the analogous detectors record the same picture element of the scene without offset.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
106 words
A method for improving the resolution of images of objects taken by a solid state apparatus using at least two sets of solid state detector elements with each set having sensing element areas sensitive to a different wave band of signals of electromagnetic energy, comprising: (a) systematically offsetting said sets of solid state detector elements each set being sensitive to different wave bands of signals of electromagnetic energy from the other so as to form subpicture elements sensitive to the different wave bands; and (b) resolving into an image by computer program means and recording means the signals of electromagnetic energy received by the subpicture elements.
Claim 2
Independent Claim
106 words
A method for improving the resolution of images of objects taken by a solid state apparatus using at least two sets of solid state detector elements with each set having sensing element areas sensitive to a different wave band of signals of electromagnetic energy, comprising: (a) systematically offsetting said sets of solid state detector elements each set being sensitive to different wave bands of signals of electromagnetic energy from the other so as to form subpicture elements sensitive to the different wave bands; and (b) resolving into an image by computer program means and recording means the signals of electromagnetic energy received by the subpicture elements.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein there are at least three different sets of detector elements sensitive to said different wave bands of electromagnetic energy.
Claim 4
Dependent Claim
15 words
The method of claim 2 wherein the three different wave bands are visible wave bands.
Claim 5
Dependent Claim
57 words
The method of claim 3 wherein the different wave bands are the colors red, green, and blue, and in which the different sets of detector elements offset each other a third of the sensing element areas of each other so as to form 9 separate subpicture elements from each detector element of each set of detector elements.
Claim 6
Dependent Claim
65 words
The method of claim 1 wherein the sets of detector elements in said solid state apparatus offset each other in one direction only, and the apparatus forms images while in a fixed position on a vehicle selected from a space vehicle and an airborne vehicle wherein said vehicle is moving in a direction substantially perpendicular to the direction of the offsetting of said detector elements.
Claim 7
Dependent Claim
27 words
The method of claim 1 wherein the sets of detector elements offset each other in two directions perpendicular to each other and substantially in the same plane.
Claim 8
Dependent Claim
59 words
The method of claim 1 wherein it is applied to the forming of images by an available system of a developed satellite imaging apparatus whereby the formation of the subpicture elements is achieved in one dimension by the sequential sampling of signals of electromagnetic energy received by the sets of detector elements as the satellite moves across the objects.
Claim 9
Dependent Claim
20 words
The method of claim 6 wherein there is substantially no relative motion between said solid state apparatus and said objects.
Claim 10
Dependent Claim
120 words
A solid state multispectral imaging apparatus for forming images of objects using sets of solid state analogous detector elements, each set of detector elements made up of a plurality of sensing area elements wherein each set of detector elements is sensitive to a different wave band of signals of electromagnetic energy, comprising: (a) at least two sets of analogous detector elements with each detector element in each set of detector elements being offset from the analogous detector elements so as to form subpicture elements which receive the signals of electromagnetic energy; (b) computer program means for processing into data the signals of electromagnetic energy received by said subpicture elements; and (c) recording means for transforming said data into an image.
Claim 11
Dependent Claim
120 words
A solid state multispectral imaging apparatus for forming images of objects using sets of solid state analogous detector elements, each set of detector elements made up of a plurality of sensing area elements wherein each set of detector elements is sensitive to a different wave band of signals of electromagnetic energy, comprising: (a) at least two sets of analogous detector elements with each detector element in each set of detector elements being offset from the analogous detector elements so as to form subpicture elements which receive the signals of electromagnetic energy; (b) computer program means for processing into data the signals of electromagnetic energy received by said subpicture elements; and (c) recording means for transforming said data into an image.
Claim 12
Dependent Claim
70 words
The imaging apparatus of claim 9 wherein said apparatus is set in a fixed position on a vehicle selected from a space vehicle and an airborne vehicle, and in said apparatus said sets of different detector elements offset each other in one direction only and the apparatus forms images while the vehicle moves in a direction substantially perpendicular to the direction of the offsetting of the sets of detector elements.
Claim 13
Dependent Claim
27 words
The imaging apparatus of claim 9 wherein said apparatus is set in a fixed position in a vehicle selected from an airborne vehicle and a spacecraft vehicle.
Claim 14
Dependent Claim
42 words
