First Claim
Patent Images
1. A three-dimensional (3D) image signal processing method comprising:
- generating a first image based on color information and depth information obtained by a 3D image sensor;
obtaining a binning value by performing binning using a particular pixel among pixels for the depth information of the first image and pixels for the depth information that are adjacent the particular pixel; and
updating the depth information with the binning value and generating a second image by matching updated depth information with the color information.

Abstract
A three-dimensional (3D) image signal processing method increases signal-to-noise ratio by performing pixel binning on depth information obtained by a 3D image sensor, without changing a filter array detecting the depth information. The processing method may be used in a 3D image signal processor, and a 3D image processing system including the 3D image signal processor.

16. A three-dimensional (3D) image processing system comprising:
-
an image sensor configured to generate color information and depth information of an object; a first image generator configured to generate a first image based on the color information and the depth information; and an image signal processor configured to separate from the first image pixels for depth information and pixels for color information, select a particular pixel in the first image from among the pixels for depth information, obtain an average pixel value of the particular pixel and pixels for the depth information in the first image that are adjacent the particular pixel, update the depth information of the particular pixel using the average pixel value, and generate and output a second image by matching the updated depth information with the color information. - View Dependent Claims (17)
