Abstract:
A method and digital imaging device, such as a digital camera module, is provided for digital imaging. The method includes the step of determining a signal-to-noise ratio associated with a first pixel location of a plurality of pixel locations and a signal-to-noise ratio associated with a second pixel location of the plurality of pixel locations, and the steps of assigning a first exposure time to the first pixel location in response to the signal-to-noise ratio associated with the first pixel location and assigning a second exposure time different from the first exposure time to the second pixel in response to the signal-to-noise ratio associated with the second pixel location. The method further includes the step of exposing the first pixel location for the first exposure time while exposing the second pixel location for the second exposure time to create a digital image.
