Artificial aperture adjustment for synthetic depth of field rendering

An imaging system, comprising:

• a programmable control device;
• and
• a memory coupled to the programmable control device, wherein instructions are stored in the memory, and wherein the instructions, when executed, cause the programmable control device to:
• obtain a designated, artificial aperture value that modifies an initial aperture value of an image frame, wherein the designated, artificial aperture value modifies an amount of synthetically produced blur within the image frame;
• determine an aperture adjustment factor based on the designated, artificial aperture value and a tuning aperture value for rendering the image frame, wherein the tuning aperture value is associated with one or more default shallow depth of field (SDOF) parameters;
• modify, based on the aperture adjustment factor, the one or more default SDOF parameters to obtain updated SDOF parameters for performing one or more SDOF operations;
• and
• render an updated SDOF image frame using the updated SDOF parameters to perform the one or more SDOF operations.

An image processing method, comprising:

• obtaining a designated, artificial aperture value that modifies an initial aperture value of an image frame, wherein the designated, artificial aperture value modifies an amount of synthetically produced blur within the image frame;
• determining an aperture adjustment factor based on the designated, artificial aperture value and a tuning aperture value for rendering the image frame, wherein the tuning aperture value is associated with one or more default shallow depth of field (SDOF) parameters;
• modifying, based on the aperture adjustment factor, the one or more default SDOF parameters to obtain updated SDOF parameters for performing one or more SDOF operations;
• and
• rendering an updated SDOF image frame using the updated SDOF parameters to perform the one or more SDOF operations.
