摘要： A movement detection circuit, a motion estimation circuit and associated movement detection method are provided. The movement detection circuit includes a candidate searching module including a first-frame and a second-frame candidate circuits, an object selection module including a first selection circuit, a second selection circuit, and a motion vector calculation circuit. The first-frame and the second-frame candidate circuits respectively locate a first and a second first-frame candidate positions in the first frame and locates a first and a second second-frame candidate positions in the second frame. The first-frame object selection circuit identifies one of the first and the second first-frame candidate positions as a first-frame object position, and the second-frame object selection circuit identifies one of the first and the second second-frame candidate positions as a second-frame object position. An object motion vector representing movement of an object based on the first-frame and the second-frame object positions is calculated.

摘要： A first motion vector detecting unit calculates a first matching error by detecting a first motion vector based on a first frame and a second frame. A second motion vector detecting unit calculates a second matching error by detecting a second motion vector based on the second frame and a third frame. A local determining unit determines whether a discontinuously moving object is present in a continuously moving background, based on an absolute difference value between the first motion vector and the second motion vector, and the first and second matching errors. An integrating unit integrates determination values for each block within a frame. A determining unit determines whether an image signal is a specific moving image in which the discontinuously moving object is present in a continuously moving background, based on a pattern of integrated values of at least two frames.

摘要： Methods and apparatus to detect commercial advertisements associated with media presentations are disclosed. An example method involves receiving a video frame and detecting a change in box-formatting between the video frame and a subsequent video frame. A transition between the video frame and the subsequent video frame is indicated as a commercial advertisement transition based on the detected change in box-formatting.

摘要： Systems and methods for adjusting the frame rate of transmitted video based on the level of motion in the video are provided. Some methods can include receiving a video data stream from a video capture device at a first frame rate, identifying a level of motion in one or more frames of the video data stream at a regular interval, identifying a plurality of second frame rates for the video data stream, and transmitting the video data stream to a storage device or a display device at respective ones of the plurality of second frame rates, wherein each of the plurality of second frame rates can correspond to the level of motion in a respective frame of the video data stream.

摘要： A rifle scope including a display, at least one optical sensor to capture video of a view area, and image processing circuitry coupled to the display and the at least one optical sensor. The image processing circuitry is configured to select visual elements within a sequence of frames of the video and to align the visual elements within adjacent frames of the sequence of frames to produce a video output corresponding to the view area that is stabilized relative to a target. The image processing circuit is configured to provide the video output to the display.

摘要： A motion estimation technique finds first and second candidate bi-directional motion vectors for a first region of an interpolated frame of video content by performing double ended vector motion estimation on the first region. One of these candidate bi-directional motion vectors is selected, and used to identify a remote region of the interpolated frame. This remote region is located at an off-set location from the first region, and is found based on an endpoint of the selected candidate bi-directional motion vector. A remote motion vector for the remote region of the interpolated frame is obtained, and one or more properties of this remote motion vector are used to bias a selection between the first and second candidate vectors.

摘要： A motion detection method includes an extracting circuit generating a first representative data according to a first image in an image signal outputted by an image sensor, a buffering circuit storing the first representative data, the extracting circuit generating a second representative data according to a second image in the image signal, the buffering circuit storing the second representative data and outputting the first representative data to a comparing circuit, and the comparing circuit comparing the first representative data and the second representative data, to generate a motion detection result. When the motion detection result represents “motion”, an image-signal-processing circuit of an image signal processor enters active state to generate output signal. By means of the motion detection method, in an imaging device, the image-signal-processing circuit of the image signal processor can switch between active state and power-off/power-saving state even when there is no additional infrared sensor.
