Embodiment Construction

[0021] In accordance with the principles of the present invention, an advantageous system is provided that is particularly useful for smartphones or tablets, but may be identified with other applications. Generally, to improve captured images or videos, a function is provided in which sensor information is used to generate a virtual three-dimensional (3D) model of a scene in view of a smartphone's sensors. The virtual 3D model is then used to generate a two-dimensional (2D) brightened image. Apply Lighten Image to the captured image of the scene to improve the brightness of the captured image or video. If desired, a virtual light source can be implemented as part of this operation, which can be moved, adjusted or modified in the virtual 3D space, if desired, to adjust the brightened image and thus the brightened image.

[0022] Embodiments of the present invention are applicable to image, video or other view capture applications. In some embodiments, a "live" function is pro...

Abstract

Method for providing virtual light and a processing system thereof are provided. The method includes: implementing a virtual light source on a mobile device; receiving a user input, wherein the user input instructs the mobile device to capture 2D output images of current views of a plurality of device sensors in real time; receiving a plurality of sensor outputs, wherein the plurality of sensor outputs are generated by using the plurality of device sensors to sense information from the current views, and the plurality of sensor outputs include initial 2D frames sensed by one or more of the plurality of device sensors; and responding to reception of the plurality of sensor outputs and the user input, generating a 2D output image on the mobile device according to regulation on the virtual light source and the initial 2D frames, wherein generation of the 2D output image is real time relative to reception of the plurality of sensor outputs. In the embodiment of the invention, the virtual light source is used to replace a flash lamp, the brightness of images captured by the mobile device is improved, and the images are not blurred due to movement or shake.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 175,577, filed June 15, 2015, which is incorporated by reference in its entirety. technical field [0003] The present invention relates to a method and a system for providing virtual light to an image, and more particularly to a method and a system for providing virtual light to an image through one or more virtual light sources in a virtual three-dimensional space. Background technique [0004] An electronic device, such as a camera or other image capture tool, can capture a photograph based on the light illuminating the scene. In low light conditions, ambient light alone may not sufficiently illuminate a scene, and images captured from that scene may be dark or underexposed. [0005] To improve illumination in low light conditions, many image capture tools or devices may include a flash that produces a flash of light to supplement ambient light ...
