Abstract: The present invention discloses a method for acquiring automatic exposure control parameters and a method for controlling automatic exposure control parameters and an imaging device. The core idea is to take the brightness weighted average value obtained according to brightness distribution weighted statistics of the image as the exposure control parameter. Then through adjusting the weighted coefficient of pixels in different brightness regions, control the influence of the pixel concentrated brightness regions on the brightness average value. Because the brightness distribution is the basis for determining weighted statistics, the control method of the present invention is not influenced by the scene assumption. Rather it can be universally adapted to a variety of different scenes, and the exposure control effect is not influenced by the position of scenes in the actual bright region/dark region and block distribution.

Abstract: A method and a device for describing and capturing video objects are provided in the embodiments of the present application, including: capturing video images to generate video sequences, generating a video object tracking sequence (OTS) according to the video sequences, and generating video object descriptors (ODs) according to the video OTS and video sequences. Therefore, in a generated video object tracking sequence (OTS), the video object region tracking number (TID) is used to capture and track video objects. This makes it unnecessary to create a video object descriptor (OD) for each video object on a frame-by-frame basis. Therefore, the quantity of video ODs is reduced, thereby suiting the application requirement for the intelligent video interaction and accelerating the search of the video materials.
