A method performed in a multi-sensor video camera having a first and a second sensor (102a, 102b) with partly overlapping fields of view, comprising: receiving a first video frame and a second video frame being simultaneously captured by the first sensor and the second sensor, respectively, wherein each of the first and the second video frame (108a, 108b) has a non-overlapping portion (118a, 118b) where it does not overlap with the other of the first and the second video frame (108a, 108b), and an overlapping portion (128a, 128b) where it overlaps with the other of the first and the second video frame (108a, 108b), generating a frame of a first video stream by joining together image data (A, B) from the non-overlapping portions (118a, 118b) of the first and the second video frame (108a, 108b) with image data (A') from the overlapping portion of the first video frame only, characterized by generating a frame (304, 404) of a second video stream, wherein the frame (304, 404) of the second video stream includes image data (B') from the overlapping portion of the second video frame, processing the frame of the first video stream and the frame (304, 404) of the second video stream in parallel, wherein the processing of the frame (304, 404) of the second video stream includes preparing an overlay (306, 406) based on the image data (B') from the overlapping portion of the second video frame, and adding the overlay (306, 406) to the processed frame of the first video stream at a portion thereof corresponding to the overlapping portion of the first video frame, wherein image data (A') from the overlapping portion of the first video frame is blended with image data (B') from the overlapping portion of the second video frame in at least one of the steps of preparing the overlay and adding the overlay, wherein, if the image data (A') from the overlapping portion of the first video frame is blended with image data (B') from the overlapping portion of the second video frame in the step of preparing the overlay, the frame of the second video stream further includes image data (A') from the overlapping portion of the first video frame, the step of preparing the overlay includes blending image data (B') from the overlapping portion of the second video frame with image data (A') from the overlapping portion of the first video frame, and, in the step of adding the overlay, the overlay replaces image data (A') of the processed frame of the first video stream in the portion corresponding to the overlapping portion of the first video frame. receiving a first video frame and a second video frame being simultaneously captured by the first sensor and the second sensor, respectively, wherein each of the first and the second video frame (108a, 108b) has a non-overlapping portion (118a, 118b) where it does not overlap with the other of the first and the second video frame (108a, 108b), and an overlapping portion (128a, 128b) where it overlaps with the other of the first and the second video frame (108a, 108b), generating a frame of a first video stream by joining together image data (A, B) from the non-overlapping portions (118a, 118b) of the first and the second video frame (108a, 108b) with image data (A') from the overlapping portion of the first video frame only, characterized by generating a frame (304, 404) of a second video stream, wherein the frame (304, 404) of the second video stream includes image data (B') from the overlapping portion of the second video frame, processing the frame of the first video stream and the frame (304, 404) of the second video stream in parallel, wherein the processing of the frame (304, 404) of the second video stream includes preparing an overlay (306, 406) based on the image data (B') from the overlapping portion of the second video frame, and adding the overlay (306, 406) to the processed frame of the first video stream at a portion thereof corresponding to the overlapping portion of the first video frame, wherein image data (A') from the overlapping portion of the first video frame is blended with image data (B') from the overlapping portion of the second video frame in at least one of the steps of preparing the overlay and adding the overlay, wherein, if the image data (A') from the overlapping portion of the first video frame is blended with image data (B') from the overlapping portion of the second video frame in the step of preparing the overlay, the frame of the second video stream further includes image data (A') from the overlapping portion of the first video frame, the step of preparing the overlay includes blending image data (B') from the overlapping portion of the second video frame with image data (A') from the overlapping portion of the first video frame, and, in the step of adding the overlay, the overlay replaces image data (A') of the processed frame of the first video stream in the portion corresponding to the overlapping portion of the first video frame.
