摘要:
To allow better quality rendering of video on any display, a method is proposed of encoding, in addition to video data (VID), additional data (DD) comprising at least one change time instant (TMA-1) indicating a change in time of a characteristic luminance (CHRLUM) of the video data, which characteristic luminance summarizes the set of luminances of pixels in an image of the video data, the method comprising: -generating on the basis of the video data (VID) descriptive data (DED) regarding the characteristic luminance variation of the video, the descriptive data comprising at least one change time instant (TMA-1), and-encoding and outputting the descriptive data (DED) as additional data (DD).
摘要:
A camera and system comprising a camera in which, during exposure, the ratio of the distance between the lens and the sensor and the focal length is changed. The rate of change is set such that motion invariant imaging is achievable for practical speed ranges, i.e. speed of up to at least 5 km/hour at 2 meter distance of the lens, by deconvoluting the compound image. Preferably the achievable speed range is at least twice as high. A linear motion of the sensor is preferred.
