Abstract:
1. An electronic image capture system for capturing a reduced noise image of a scene, comprising a detector array and an image processing apparatus, the detector array being arranged to provide to the image processing apparatus data representing at least one image of a scene detected by the array, and the image processing apparatus storing a noise model that characterizes the noise performance of the image capture system, wherein the image processing apparatus is arranged to perform operations comprising: based on the image data and the noise model, identifying one or more portions of the scene that are predicted to contribute disproportionately to visible noise in an image formed from said image data; and based on the identified portions of the scene and the noise model, determining an exposure pattern for the image capture system that is predicted to produce multiple exposures of the scene that are combinable to produce an image with a minimal predicted noise.
