|20160105597||CMOS VIDEO CAMERA AND METHOD FOR FILLING LIGHT - The present disclosure provides a Complementary Metal Oxide Semiconductor (CMOS) video camera and method for filling light. The method includes: acquiring a frame interval and an exposure time of each line of pixels; determining a strobe period according to the acquired frame interval and exposure time of each line of pixels; and filling light for each frame of an image by using a light-filling lamp according to the determined strobe period and a predetermined duty cycle, wherein the predetermined duty cycle is larger than 0 and lower than 1. According to the present disclosure, the light-filling efficiency is improved, and the working life of the light-filling lamp is prolonged.||04-14-2016|
|20150341598||METHOD OF MULTI-SCREEN PAGINATION PLAYING - The present disclosure provides a method and terminal of multi-screen pagination playing. The method includes the follows. A video channel list may be established. At least one video channel may be selected from the video channel list. A pagination number of a display screen may be determined, based on number of selected video channel and split-screen number of the display screen. The selected video channels may be played on each split-screen of a respective pagination, based on sequence of the selected video channels. In the present disclosure, a one-to-one correspondence may be configured in sequence for video channels of different devices and playing pictures of each pagination, each split-screen.||11-26-2015|
|20150229841||TARGET TRACKING METHOD AND SYSTEM FOR INTELLIGENT TRACKING HIGH SPEED DOME CAMERA - Disclosed is a target tracking method for an intelligent tracking high speed dome, comprising: in the process of target tracking, when the position coordinates of a newly selected target in the acquired tracking image are received, matching the position coordinates of the newly selected target in the tracking image, using the target corresponding to the position coordinates of the newly selected target in the tracking image as a current target, and extracting the characteristics of the current target; tracking the current target according to the characteristics thereof, and updating in real time the position coordinates of the current target in the tracking image; converting the updated position coordinates of the current target into speed dome identifiable horizontal rotation value P, vertical rotation value T and magnification factor value Z; adjusting in real time the magnification factor of the speed dome according to the value Z, and controlling in real time the rotation of the speed dome according to the value P and the value Z. When a plurality of the targets appear in a specific scene, the present invention can lock a concerned target and track the target selectively, thus solving the previous problem of tracking an unconcerned target; furthermore, the method of the present invention can reselect and track a target by locking the target manually, thus solving the problem of losing the target.||08-13-2015|
|20130070969||METHOD AND SYSTEM FOR PEOPLE FLOW STATISTICS - A method and system for people flow statistics is disclosed in the invention, wherein said method comprises: multi-types of classifiers connected in parallel are used to perform the human head detection in the current image, the respective human heads in the current image are determined; the respective determined human heads are tracked to form the human head target movement tracks; and the people flow is counted at the direction of the human head target movement track. It can be seen, a plurality of classifiers connected in parallel are used in the invention, multi-types of human head targets, such as dark colored hair, light colored hair and caps of various colors, and the like, can be detected simultaneously.||03-21-2013|
