Blending real and virtual focus in a virtual display environment

A computer-implemented method for generating a virtual scene rendering of a captured scene, the method comprising:

• determining a camera position of a camera in a stage environment;
• determining a display position of a virtual scene display in the stage environment;
• determining focus parameters of the camera;
• determining a depth value for a given virtual scene element viewable as an image on the virtual scene display, wherein the depth value corresponds to a virtual distance in the virtual scene between the given virtual scene element and a virtual camera viewpoint located at the camera position;
• determining a desired focus model, based at least on:
• the focus parameters of the camera;
• the depth value;
• and
• a desired lens effect;
• determining an adjusted focus for the given virtual scene element based on the desired focus model;
• and
• applying at least a portion of the adjusted focus to at least one of:
• the focus parameters of the camera;
• the image of the given virtual scene element on the virtual scene display;
• or
• pixels representing the given virtual scene element in a composite image, captured by the camera, of the stage environment and the virtual scene display.
