US Patent 9639945 Depth-based application of image effects

An image such as a light-field image may be captured with a light-field image capture device with a microlens array. The image may be received in a data store along with a depth map that indicates depths at which objects in different portions of the image are disposed. A function may be applied to the depth map to generate a mask that defines a gradual transition between the different depths. An effect may be applied to the image through the use of the mask such that applicability of the effect is determined by the mask. A processed image may be generated. The first effect may be present in the processed image, as applied previously. The processed image may be displayed on a display device. If desired, multiple effects may be applied through the generation of multiple masks, depth maps, and/or intermediate images prior to generation of the processed image.
