Abstract:
1. A video camera with means to record various state signals of the video camera for efficient video compression, comprising: video signals; storing means for storing digital information; data format; video recording means that records said video signals in said storing means according to said data format; luminosity sensing means; luminosity recording means that receives luminosity signals from said luminosity sensing means and records said luminosity signals in said storing means according to said data format; movement sensing means that generates camera movement signals of the video camera; movement recording means that receives said camera movement signals from said movement sensing means and records said camera movement signals in said storing means according to said data format; frame index generating means that generates a periodic frame index, which has a sufficiently large periodicity, and assigns it to each frame of said video signals; frame index recording means that records said periodic frame index in said storing means according to said data format; zooming state sensing means that generates zooming state signals of the video camera; zooming state recording means that receives said zooming state signals from said zooming state sensing means and records said zooming state signals in said storing means according to said data format; aperture state sensing means that generates aperture state signals of the video camera; aperture state recording means that receives said aperture state signals from said aperture state sensing means and records said aperture state signals in said storing means according to said data format; focus state sensing means that generates focus state signals of the video camera; focus state recording means that receives said focus state signals from said focus state sensing means and records said focus state signals in said storing means according to said data format; camera identification number generating means that selects a camera identification number from a sufficiently large pool of numbers; camera identification number recording means that records said camera identification number, which is generated by said camera identification number generating means, in said storing means according to said data format; and initial state entering means that enters initial movements of the video camera when recording is started.
