Abstract
A method and camera for generating a high dynamic range (HDR) image comprising the following steps: receiving a first optical signal from a lens and generating a first output signal at a first image acquisition chip, wherein the first image acquisition chip is coated with a first partial reflection coating; reflecting the first optical signal off the first partial reflection coating to create a second optical signal such that the second optical signal has a lower intensity than the first optical signal; receiving the second optical signal and generating a second output signal at a second image acquisition chip; and combining the first and second output signals to create the HDR image.
