1. A method for generating an image for display on a camera device, the method comprising: receiving an input via a user interface device that displays an image of a scene at which a camera lens of the camera device is pointing, wherein the input is associated with a selection region of the user interface device; generating an edits mask based on a plurality of matching image patches, which are based on the input and a high dynamic range (HDR) image generated by the camera device, wherein each matching image patch included in the plurality of matching image patches corresponds to a different image frame included in a set of sequential image frames of the scene; performing a tone mapping operation based on the edits mask and the HDR image in order to generate a tone mapped HDR image; and performing a metering operation based on the edits mask and the tone mapped HDR image in order to generate metering parameters for subsequent frame capturing operations.
