HIGH DYNAMIC RANGE IMAGING

摘要

A method for high dynamic range imaging using more than two capture intervals, where images are captured in a repeating sequence that avoids interlace bounce, and overlapping groups of combined images form composite frames for output, and an imaging system comprising an imaging array, processing means and a display, wherein the imaging array is operable to capture a succession of images by detecting incident light and the processing means is operable to process said images as required, and pass the processed images to the display for output.

1. A method for high dynamic range imaging comprising the steps of:
defining n capture intervals where n is 3 or above; and capturing a series of images at the said capture intervals in a repeating sequence of 2n−2 steps, wherein the first n steps of the sequence comprise one of each capture interval, and the n−2 capture intervals between the first and the nth capture intervals are then duplicated for the subsequent steps of the sequence and wherein each of the n−2 capture intervals between the first and the nth capture intervals that is in an odd position in the first n capture intervals of the sequence maintains an odd position when duplicated in the subsequent steps of the sequence and each of the n−2 capture intervals between the first and the nth capture intervals that is in an even position in the first n capture intervals within the sequence maintains an even position when duplicated in the subsequent steps of the sequence.
