System and Method for Determining a Zoom Factor of Content Displayed on a Display Device

摘要

A system, computer-readable storage medium storing at least one program, and a computer-implemented method for determining a zoom factor of content displayed on a display device is presented. An image is obtained from a camera oriented toward a viewing position of the display device, where the image includes a viewer of the display device. The image is normalized based on specification of the camera to produce a normalized image. The normalized image is analyzed to determine a distance between the display device and the viewer of the display device. A zoom factor for content is determined based on the distance between the display device and the viewer of the display device. Content is displayed on the display device using the zoom factor.

1. A computer-implemented method for determining a zoom factor of content displayed on a display device, performed on a host device having at least one processor and memory storing at least one program for execution by the at least one processor to perform the method, comprising:
obtaining an image from a camera oriented toward a viewing position of the display device, the image including a viewer of the display device; after obtaining the image, normalizing the image automatically and without user intervention based on a specification of the camera to produce a normalized image, wherein the specification of the camera includes one or more of optical specifications of a lens of the camera, specifications of an image sensor of the camera, and a crop factor of the image sensor of the camera; analyzing the normalized image to determine a distance between the display device and the viewer of the display device; determining a zoom factor for content based on the distance between the display device and the viewer of the display device; and displaying content on the display device using the zoom factor.
