1. A method for generating an image for a scene from a first image of the scene and a second image of the scene, the first image having a first exposure value and including a first pixel, the second image having a second exposure value smaller than the first exposure value and including a second pixel, comprising: generating, at a third exposure value intermediate between the first and second exposure values, a third image from at least the first and second images, mapping a first intensity value of the first pixel from the first exposure value to the third exposure value and mapping a second intensity value of the second pixel from the second exposure value to the third exposure value.
