Abstract

The invention provides a video signal processing device, video signal processing method and video signal processing program. A video signal processing device for compressing input video and transmitting compressed video data onto a network, the video signal processing device including a compression section configured to compress the video, and a noise reduction section configured to reduce noise in video data by a predetermined amount of noise reduction according to the size of the video data transmitted onto the network.

Description

technical field [0001] The present invention relates to a video signal processing device, a video signal processing method, and a video signal processing program, and for example, to video signal processing suitable for application to a surveillance camera system, providing reduced noise in input video data and providing a smaller transmission data size A device, a video signal processing method, and a video signal processing program. Background technique [0002] Previously, so-called analog camera systems were often used as surveillance camera systems. Each such system has a video recorder or other video recording device connected to the camera with a signal line so that video signals captured by the camera are provided to the video recording device via the signal line for recording. In recent years, however, so-called IP (Internet Protocol) camera systems have become increasingly popular due to the widespread use of the Internet. In such a camera system, video data capt...
