The following description of the preferred embodiments of the present invention is intended to be

1 is a schematic diagram of a system of a smart video and playback device in accordance with a preferred embodiment of the present invention. The smart video and playback device 100 includes a camera 110, a smart image processing device 120, and a memory device 130. The camera 110 is configured to capture a live image and transmit the live image to the smart image processing device 120 at the back end. The intelligent image processing device 120 can dynamically adjust the image quality according to the received live image. The image quality can include the resolution of the video stream, the compression ratio, the screen update rate, the image group size or a combination thereof, or other picture quality. The image parameters are used to adjust the corresponding amount of image data, and the image quality-adjusted live image is stored in the memory device 130. Since not all live images are stored according to the amount of normal image data, the storage efficiency of the memory device 130 can be maximized.

In surveillance systems, anomalous objects are typically objects that monitor moving objects in an image or enter a particular alert zone. For example, the area that the camera 110 is alerted to is a residential area, if there is no moving object in the residential area. At this time, the intelligent image processing device 120 determines that the scene is normal, and there is no immediate danger. Therefore, the image quality received from the camera 110 is dynamically adjusted according to this, and the resolution, compression ratio, and screen update rate of the video stream are analyzed. The image parameters are adjusted to reduce the amount of corresponding image data. On the other hand, if a person suddenly enters the residential area, the smart image processing device 120 determines that the scene is abnormal, so the image quality received from the camera 110 is dynamically adjusted according to this, and the resolution and compression ratio of the video stream are analyzed. The image parameters such as the screen update rate are adjusted, for example, the normal parameter value is returned to restore the corresponding image data amount.

In order to dynamically adjust the image quality, the intelligent image processing device 120 further includes a data transmission interface 121, an image determination component 122, and an image adjustment component 123. The data transmission interface 121 can be a WiFi, 3G, USB or other wired or wireless data transmission interface for establishing a connection with the corresponding data transmission interface 111 of the camera 110. Accordingly, the camera 110 can transmit the captured video stream to the data transmission interface 121 of the smart image processing device 120 through the data transmission interface 111. The image determining component 122 is configured to determine whether the image transmitted by the data transmission interface 121 has an abnormal condition. When an abnormal condition occurs, the image determining component 122 generates a driving signal EN to drive the image adjusting component 122 to adjust the received image stream. An image quality.

In order to generate the driving signal EN, in an embodiment, the image determining component 122 further includes a comparison module 126, a first storage module 124, and a second storage module 125. The plurality of images in the image stream transmitted by the data transmission interface 121 are sequentially stored in the first storage component 124 and In the second storage component 125, for example, the first storage component 124 stores the first image in the image stream, and the second storage component 125 stores the second image in the image stream, the second image following the first image. The comparison module 126 compares the first image of the first storage module 124 with the second image stored by the second storage module 125 to determine whether the received image has an abnormal condition. The method for determining whether the image is abnormal by the comparison module 126 may use a background subtraction method, a temporal difference method (Temporal Differencing) or an optical flow detection method (Optical Flow) to determine whether there is a moving object. It is worth noting that other detection methods can also be used in the present invention. The comparison module 126 can further generate a driving signal EN according to the result of the determination, and drive the image adjusting component 123 to adjust the image stream quality output by the image determining component 122 to adjust the corresponding image data amount, and the image is processed. The quality-adjusted video stream is stored in the memory device 130. Since the image parameters of the stored video stream are dynamically adjusted according to the scene conditions of the camera 110, the amount of data of the video stream is dynamically changed. For example, when the scene condition is abnormal, the amount of data of the video stream can be increased. When the scene condition returns to normal, that is, when there is no change in the image, the amount of data streamed by the image stream is reduced, thereby maximizing the storage efficiency of the memory device 130.

In addition, the smart image processing device 120 further includes a playback component 127 for playing the video stream data stored by the memory device 130. The playback component 127 is configured to decode the video stream data stored by the memory device 130 and transmit it to a display device 140 for playback. The playback component 127 is further selectable according to the video stream data stored by the memory device 130. Corresponding to smart play. That is, when the video stream data stored in the memory device 130 is the data when the image is not changed, the playback component 127 transmits the video stream to the display device 140 for playback in a fast playback manner. On the other hand, when the video stream data stored in the memory device 130 is the data when the image is abnormal, the playback component 127 transmits the video stream to the display device 140 for playback in the normal playback mode, that is, according to the recording time. The fast play mode is, for example, playing 60 images in one second and adding 120 images in one second. However, this is only an embodiment and does not limit the new application. To implement the smart play function, the playback component 127 further includes a determination module 128 for determining the video stream data stored by the memory device 130. In an embodiment, the determining module 128 can determine the corresponding playing mode by detecting image parameters forming a video stream data.

In summary, the smart video recording and playback device of the present invention can dynamically adjust the image parameters of the video stream according to the scene of the camera to maximize the storage efficiency of the memory device, and can also be used according to the memory device during playback. The stored image stream data status dynamically changes the playback speed and reduces the data search time.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any one skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
