Image recording system
An image recording system including a component capable of displaying and processing of images such as a central processing unit (CPU)/digital signal processor (DSP) that may be installed in a network video recorder (NVR) so that the image recording system may be used to implement a video summary/video synopsis technology in an embedded NVR/digital video recorder (DVR)/set-top box (SETTOP) system having a Host CPU and a plurality of DSP cores.
1. An image recording system comprising:
a host system and at least one sub-system configured communicate with each other using a peripheral component interconnect express (PCIe) communication method,
wherein the host system is further configured to store an original image acquired by at least one network camera and a compressed video summary image of the original image,
wherein the at least one sub-system is further configured to receive the original image from the host system, process the original image, and generate a video summary corresponding to a specific time interval of the original image,
wherein the image recording system is configured to display the video summary which comprises object information of an object detected by an advanced motion detection (AMD) method during the specific time interval of the original image and time information of the object, and
when more than one object is detected in a specific area of the displayed video summary during the specific time interval, the detected objects are displayed in an overlay state in the specific area.
2. The image recording system of claim 1 , wherein the displayed video summary comprises all of the objects detected using the AMD method and detection time information of each of the objects during the specific time interval.
3. The image recording system of claim 1 , wherein when more than one object is detected in the specific area, an indicator showing the number of the detected objects is displayed in one of the specific area and an area near the specific area, using an overlapping display method.
4. The image recording system of claim 1 , wherein when more than one object is detected in the specific area, time information and image information of each of the detected objects is displayed in an overlay state in the specific area.
5. The image recording system of claim 4 , wherein when a user selects the specific area, the time information and the image information of the each of the objects are displayed as a two or three-dimensional thumbnail and in the form of at least one from among a hierarchical list, a panorama icon, a circle, and a polyhedron.
6. The image recording system of claim 5 , wherein the thumbnail comprises the image information of the object, the object information of the object, and time information corresponding to a time when the object appears, and
wherein the object information comprises at least one of color information of the object, size information of the object, and area information of the object.
7. The image recording system of claim 1 , wherein when more than one object is detected in the specific area, all of the detected objects are displayed in a timeline form when the user selects the specific area.
8. The image recording system of claim 5 , wherein when all of the detected objects are displayed in the form of the polyhedron, each of the detected objects is displayed in an overlay state on each surface of a polyhedron.
9. The image recording system of claim 1 , wherein the video summary corresponding to the specific time interval comprises event information detected by the AMD method during the specific time interval displayed in a time sequential order starting from a time when an event is generated.
