Imaging device with blur reduction system including a primary array and at least one navigation array

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.

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.
