Abstract
An embodiment of the invention is a method of generating a final exposure setting, including, (a) selecting one of a number of predetermined exposure settings as a current exposure setting for a solid state camera having a camera imager, (b) generating a captured scene by the camera imager using the current exposure setting, (c) selecting according to an automated search methodology another one of the exposure settings to be the current setting in response to the captured scene being underexposed or overexposed, and, (d) repeating (b) and (c) until the captured scene is neither underexposed or overexposed.
