Abstract
Official abstract text for this publication.
This disclosure describes techniques for producing high dynamic range images by applying a variable weighting factor to a sample prior to combining the sample with another sample. In one example, a method includes sampling a first pixel cell signal at a first time to produce a first sample, sampling a second pixel cell signal at a second time to produce a second sample, applying a variable weighting factor to the second sample, wherein the variable weighting factor is defined based on a function, and combining the first sample and the weighted second sample.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: sampling a first pixel cell signal at a first time to produce a first sample; sampling a second pixel cell signal at a second time to produce a second sample; applying a first variable weighting factor to the first sample, wherein the first variable weighting factor is defined based on a first function; applying a second variable weighting factor to the second sample, wherein the second variable weighting factor is defined ba…
