“…The principle of dynamic pixel management was first introduced in a 2/3" FT CCD imager used in a broadcast camera in 1994 * 1,2,3 . Then, a flexible pixel structure allowed combining the signal charge of 4 or alternatively only 3 sub-pixels in the vertical direction during readout.…”

“…It is the same as taking the maximum of all individual prime numbers in which the elements in a set are decomposed. Applied to Table 1, the maximum of prime 2 is 2 5 , for prime 3 is 3 3 , and for prime 5 it is 5. The least common multiple of the numbers of Table 1 is 4320 = 2 5 .3 3 .5 = [5,3,1,0,0,0]LP6.…”

“…The imager and its camera are principally designed for the 16:9 broadcast video aspect ratio. With the DPM principle [5,6] some other aspect ratios are possible. The image area of the HD-DPM CCD can be put in a 1440P imaging mode (Figure 2a), which results in a surplus of scanning lines.…”

A novel way for capturing native 1080P, 1080I and 720P at 16:9 aspect ratio and a CineScope aspect ratio in 1080P of 2.37:1 will be presented. The architecture of the multi-format HDTV camera head is based on a newly designed Frame Transfer CCD-imager. It enables the design of a camera head that has multiple formats available at the HD-SDI (SMPTE 292M) output of the camera head itself. The camera head utilizes three Frame Transfer (2/3 inch) CCDs with 9.2 Mpixels each (including overscan). Through the use of a 12-phase system all the vertical resolutions of the SMPTE 274M and SMPTE 296M standards are possible. Under software control (Dynamic Pixel Management ™) these pixels are prearranged , at the CCD, into image cells. The image diagonal (11 mm) is independent of spatial resolution and therefore the same for all scanning formats. The video processing chain consists of three 12-bit ADCs followed by two newly designed ASICs that allow multi-format video processing. Amongst many other outputs, the ASICs have an SMPTE 292M-compatible 20-bit parallel output can be serialized to obtain a HD-SDI output at the camera head. The above video chain offers full digital processing capability.
