An electronic image capture system 1 for capturing a reduced noise image of a scene 2 comprises a detector array 8 and an image processing apparatus 10. The detector array 8 is arranged to provide to the image processing apparatus data 18 representing at least one image 6 of a scene detected by the array 8, and the image processing apparatus holds a noise model that substantially characterizes the noise performance of the image capture system. The image processing apparatus is arranged to identify, using the image data and the noise model, one or more portions of the scene that would contribute disproportionately to visible noise in an image formed from said image data, and to select an exposure pattern on the basis that said selected exposure pattern will reduce the contribution to the visible noise when exposures from said selected exposure pattern are combined to form the reduced noise image.
