Abstract

A light compensating system in accordance with this invention comprises a plurality of light emitting devices, an image capturing device, and a processing device. The processing device is respectively coupled to the plurality of light emitting devices and the image capturing device. Each light emitting device is used for emitting light to illuminate a certain area in space. The image capturing device is used for capturing a first image, which can be defined as a plurality of image blocks. Each image block is affected by the light from at least one corresponding light emitting device. The processing device is used for analyzing a brightness value of at least one of the plurality image block and adjusting at least one light emitting device corresponding to the analyzed image block based on the brightness value.

First claim

What is claimed is:

1. A light compensating system, comprising:
a plurality of light emitting devices, each of the light emitting devices adapted for emitting light and producing a beam pattern to illuminate different areas;
an image capturing device adapted for capturing a first image, wherein the first image comprises a plurality of image blocks and each of the image blocks is affected by the light from at least one corresponding light emitting device, wherein each of the plur…
