Interactively refining a digital image depth map for non destructive synthetic lens blur

A system comprising:

• a memory component;
• and
• one or more processing devices coupled to the memory component, the one or more processing devices to perform operations comprising:
• generating a fused depth map comprising a combination of foreground depth values and background depth values from a layered depth map of pixels of a digital image and a focal matte indicating an in-focus range of depth values of the digital image;
• determining, in response to an interaction with the digital image via a focus blur modification tool in a graphical user interface, one or more selected portions of the digital image for modifying depth values of the digital image;
• generating modified depth values for the one or more selected portions of the digital image by modifying the fused depth map, the foreground depth values, and the background depth values according to a selected focus range and a selected correction mode;
• and
• rendering the digital image to include a lens blur effect utilizing the modified depth values of the one or more selected portions of the digital image.

A non-transitory computer readable medium storing executable instructions which, when executed by a processing device, cause the processing device to perform operations comprising:

• generating a fused depth map comprising a combination of foreground depth values and background depth values from a layered depth map of pixels of a digital image and a focal matte indicating an in-focus range of depth values of the digital image;
• generating modified depth values for one or more selected portions of the digital image by modifying the fused depth map, the foreground depth values, and the background depth values according to a selected focus range and a selected correction mode comprising a focus mode or a blur mode;
• and
• rendering the digital image to include a lens blur effect utilizing the modified depth values to unblur or blur the one or more selected portions of the digital image according to the selected correction mode.
