US 11,232,579 B1 · Smoothly changing a focus of a camera between multiple target objects

Abstract

Disclosed herein is a system to smoothly change the focus of a camera between multiple targets. The system can obtain an indication of a target, an indication of a manner of focus transition between a first target and a second target, and camera settings. The system can determine a point associated with the second target, where the point has a property that focusing the camera on the point places the second target in focus, and the point is closer to the current focus point of the camera than a substantial portion of other points having the property. The system can obtain a nonlinear function indicating a second manner of focus transition between the first target and the second target. The system can change the focus of the camera between the first target and the second target by changing the focus of the camera from the current focus point to the determined point based on the nonlinear function.

A method to change a focus of a computer graphics (CG) camera between multiple target objects, the method comprising:

obtaining an indication of a first target object and a second target object among the multiple target objects, an indication of a first manner of focus transition between the first target object and the second target object among the multiple target objects, and the CG camera settings,
wherein the CG camera is configured to transition the focus from the first target object to the second target object,
wherein the CG camera settings include a current focus point of the CG camera and a region of acceptable focus;
determining a point associated with the second target object and within the region of acceptable focus,
wherein the point has a property that focusing the CG camera on the point causes the second target object to be in focus,
wherein the point associated with the second target object is closer to the current focus point of the CG camera than a substantial portion of other points having the property;
and
changing the focus of the CG camera between the first target object and the second target object by changing the focus of the CG camera from the current focus point to the point.

At least one non-transitory computer-readable storage medium carrying instructions, which, when executed by at least one data processor of a system, cause the system to:

obtain an indication of a first target object and a second target object, an indication of a first manner of focus transition between the first target object and the second target object, and camera settings, wherein a camera is configured to transition a focus from the first target object to the second target object, wherein the camera settings include a current focus point of the camera;
determine a point associated with the second target object, wherein the point has a property that focusing the camera on the point causes the second target object to be in focus, wherein the point associated with the second target object is closer to the current focus point of the camera than a substantial portion of other points having the property;
and change the focus of the camera between the first target object and the second target object by changing the focus of the camera from the current focus point to the point.

A system comprising:

at least one hardware processor;
and
at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
obtain an indication of a first target object and a second target object, an indication of a first manner of focus transition between the first target object and the second target object, and camera settings,
wherein a camera is configured to transition a focus from the first target object to the second target object,
wherein the camera settings include a current focus point of the camera;
determine a point associated with the second target object,
wherein the point has a property that focusing the camera on the point causes the second target object to be in focus,
wherein the point associated with the second target object is closer to the current focus point of the camera than a substantial portion of other points having the property;
and
change the focus of the camera between the first target object and the second target object by changing the focus of the camera from the current focus point to the point.
