Q1: What is two-dimensional & three-dimensional DNR technology?

 

A:  A noise reduction device includes a two-dimensional noise reducing unit for reducing noise by arithmetic processing within an image, a three-dimensional noise reducing unit for receiving the video signal from the two-dimensional noise reducing unit and reducing noise by arithmetic processing between images, a first noise reduction intensity setting unit for setting noise reduction intensity of the two-dimensional noise reducing unit, and a second noise reduction intensity setting unit for setting noise reduction intensity of the three-dimensional noise reducing unit. The second noise reduction intensity setting unit sets the noise reduction intensity of the three-dimensional noise reducing unit, so that the noise reduction intensity of the three-dimensional noise reducing unit becomes lower as the noise reduction intensity of the two-dimensional noise reducing unit becomes higher.
