摘要： There is provided a method performed in a multi-sensor video camera having a first and a second sensor with partly overlapping fields of view. A first and a second received video frame being simultaneously captured each has a non-overlapping portion and an overlapping portion. A frame of a first video stream is generated by joining together image data from the non-overlapping portions of the first and the second video frame with image data from the overlapping portion of the first video frame only, and a frame of a second video stream is generated to include image data from the overlapping portion of at least the second video frame. The frame of the first video stream and the frame of the second video stream are processed in parallel, wherein the processing of the frame of the second video stream includes preparing an overlay based on the image data from the overlapping portion of at least the second video frame. The overlay is added to the processed frame of the first video stream at a portion thereof corresponding to the overlapping portion of the first video frame. Image data from the overlapping portion of the first video frame is blended with image data from the overlapping portion of the second video frame in at least one of the steps of preparing the overlay and adding the overlay.

摘要： A method for image stabilization of a video stream captured by a panable and/or tiltable video camera the method comprising: generating a motor position signal, Y1, of a pan/tilt motor of the video camera; generating a gyro signal, Y2, of a gyroscopic sensor of the video camera; generating a reference signal from a predetermined movement curve of the pan/tilt motor of the video camera, the reference signal is a reference on how a pan/tilt operation of the video camera is made without shaking of the video camera; from the motor position signal, Y1, and the gyro signal, Y2, generating a combined signal, Y, according to: Y=F1*Y1+F2*Y2, wherein F1 is a low pass filter and F2 is a high pass filter; and performing image stabilization on the video stream based on a difference between the combined signal, Y, and the reference signal.

摘要： The present invention relates to the field of image encoding. In particular, it relates to methods and devices where the concept of auxiliary frames may be employed to reduce or remove the need of copying data, for reference encoding purposes, between encoders which encode different parts of an image frame. This purpose is achieved by spatially modifying (S104) original image data before encoding (S106, S108) it using the encoders, and using (S110) the encoded image data as image data of an auxiliary frame. The auxiliary frame is referenced by an inter frame comprising motion vectors corresponding to a restoration of the auxiliary frame image data back to a spatial arrangement of the original image data.
