Imaging device with blur reduction system including a primary array and at least one navigation array
First Claim
1. An imaging device comprising:
- a lens configured to focus light from a selected scene within an optical footprint;
a substrate including;
a primary array configured to acquire a desired image corresponding to a portion of the selected scene during an integration period; and
at least one navigation array configured to acquire a series of images during the integration period including a first image and a second image having common features from the selected scene, wherein the imaging array and the at least one navigation array are positioned within the optical footprint;
a correlator configured to receive the series of images from the at least one navigation array, to determine location differences of the common features of the first and second images relative to the at least one navigation array, and to provide a displacement signal indicative of imaging device translation in two planar dimensions during an interval between the first and second images based on the location differences;
a compensator configured to opto-mechanically maintain one of;
a substantially fixed relationship or a constant movement indicative of a panning movement of the imaging device between the selected scene and the primary array based on the displacement signal;
a memory configured to store at least one of the series of images from the navigation array acquired during the integration period; and
a processor, coupled to the primary array and the memory and configured to generate a composite image from the desired image from the primary array and the at least one of the series of images stored in the memory.

Abstract
An imaging device having a lens focusing light from a selected scene within an optical footprint, and a substrate including a primary array and at least one navigation array which are positioned within the optical footprint. The primary array acquires a desired image of a portion of the selected scene during an integration period and the at least one navigation array acquires a series of images during the integration period, including a first and a second image having common features from the selected scene. A correlator determines location differences of the common features of the first and second images relative to the at least one navigation array and provides a displacement signal indicative of imaging device translation in two planar dimensions during an interval between the first and second images based on the location differences.

17. A method of operating an imaging device receiving light from a selected scene within an optical footprint;
-
positioning a primary array and at least one navigation array on a common substrate within the optical footprint; acquiring, with the primary array, a desired image of a portion of the selected scene during an integration period; acquiring, with the at least one navigation array, a series of images during the integration period, the series including a first image and a second image having common features from the selected scene; determining location differences of the common features of the first and second images relative to the at least one navigation array; generating a displacement signal indicative of imaging device translation in two planar dimensions during an interval between the first and second images based on the determined location differences; and opto-mechanically maintaining a substantially fixed relationship between the selected scene and the primary array based on the displacement signal; storing, in a memory, at least one of the series of images from the navigation array acquired during the integration period; and generating, by a processor, a composite image from the desired image from the primary array and the at least one of the series of images stored in memory. - View Dependent Claims (18, 19, 20, 21, 22)

23. An imaging device comprising:
-
means for receiving light from a selected scene; means, on a substrate, for acquiring a desired image of a portion of the selected scene during an exposure period; means, on the substrate, for acquiring a series of images during the exposure period, the series including a first image and a second image having common features from the selected scene; means for determining location differences of the common features of the first and second images; means for maintaining a substantially fixed relationship between the selected scene and the substrate based on the location differences; means for storing at least one of the series of images from the navigation array acquired during the exposure period; and means for generating a composite image from the desired image of the portion of the selected scene and the at least one of the series of stored images. - View Dependent Claims (24)
