Monitoring camera system and reproduction method
View Patent ↗There is provided a monitoring camera system including at least one monitoring camera and a recorder connected to the monitoring camera. The monitoring camera captures an image of an area of a monitoring target, detects a motion in a captured video of the area, associates information relating to the motion with the captured video, and transmits the associated result to the recorder. The recorder associates the captured video of the area captured by the monitoring camera and the information relating to the motion with the monitoring camera, and records the associated result. The recorder reproduces the captured video of the area on a monitor recorded in the way that a reproduction speed of the captured video in a section in which the motion is not detected on the monitor is faster than a reproduction speed of the captured video in a section in which the motion is detected, based on the information relating to the motion.
1. A monitoring camera system comprising:
at least one monitoring camera; and
a recorder connected to the at least one monitoring camera, the recorder including a controller for controlling the operation of the recorder,
the at least one monitoring camera is configured to capture a video of an area that includes one or more frame images of a monitoring target, detect a motion of an object on a frame-by-frame basis in the one or more frames of the captured video of the area, generate detection result data on a frame-by-frame basis based on the detected motion and even if no motion is detected and regardless of a determined difference in pixel values between frames, and transmits the detection result data for each frame to the recorder,
the controller of the recorder associates the captured video of the area and the detection result data relating to the detected motion with identification information of the at least one monitoring camera, and records the detection result data, and
the controller of recorder reproduces the captured video of the area, using the detection result data for each frame, on a monitor so that a reproduction speed of the captured video in a section in which motion is not detected is faster than a reproduction speed of the captured video in a section including the one or more frames in which motion is detected, the detected motion corresponding to designated target frames with respect to the captured video of the area displayed on the monitor.
2. The monitoring camera system of claim 1 ,
wherein the target frame is a part of the area displayed on the monitor.
3. The monitoring camera system of claim 1 ,
wherein the controller of the recorder reproduces the captured video in the section in which the motion is detected at a default speed, and reproduces the captured video in the section in which the motion is not detected at the reproduction speed of 1.5 times the default speed.
4. The monitoring camera system of claim 1 ,
wherein in the target frame, a position and a size of the captured video of the area are changeable.
5. The monitoring camera system of claim 1 ,
wherein a position and a size of the target frame is designated by an user input when the captured video is displayed on the monitor.
6. The monitoring camera system of claim 2 ,
wherein a plurality of target frames are set with respect to the captured video of the area displayed on the monitor.
7. The monitoring camera system of claim 6 ,
wherein the controller of the recorder reproduces the captured video on the monitor in such a way that a reproduction is faster than a reproduction speed of the captured video in a section in which the motion is detected, based on the information relating to the motion corresponding to at least one of the target frames.
8. A reproduction method in a monitoring camera system including at least one monitoring camera and a recorder, the method comprising:
using the at least one monitoring camera, capturing a video of an area that includes a plurality of images of a monitoring target, detecting a motion of an object on a frame-by-frame basis in one or more frames of the captured video of the area, generating detection result data on a frame-by-frame basis based on the detected motion and even if no motion is detected and regardless of a determined difference in pixel values between frames, and transmitting the detection result data for each frame to the recorder, and
using a controller of the recorder, associating the captured video of the area and the detection result data relating to the detected motion with identification information of the at least one monitoring camera, and recording the detection result data,
wherein the controller of the recorder reproduces the captured video of the area, using the detection result data for each frame, on a monitor so that a reproduction speed of the captured video in a section in which motion is not detected is faster than a reproduction speed of the captured video in a section including the one or more frames in which the motion is detected, the detected motion corresponding to designated target frames with respect to the captured video of the area displayed on the monitor.
