Hi ccs-hello - as always very helpful post. But for some reason both Lodestar C and C2 can produce full colour images in 1x2 vertical binning (called 'Fast') and I've used the former camera for many of my images in my gallery linked below for some years using SX s/w. The resultant images are full size 752x580p but lack slighty in vertical resolution but this goes largely unnoticed. The 'progressive scan' etc is full-res.
Per your description, the 1x2 binning mode actually is the classic video CCD (interlaced CCD with complementary-color CMY + G) most basic read out method, known as field integration mode CCD read out.
See http://www.cloudynig...s/#entry1380277 <-- (note highly technical)
Interlaced CCD will have odd field readout and even field readout. It is the design nature of such CCD, (as opposed to progressive readout mode CCD.)
In 1x2 binning, <-- actually called neighboring line charge summation or field integration mode, is the default readout method for non long-exposure shooting conditions.
Odd field will be CCD line1+2, line 3+4, etc., forming the first field with only half of the vertical output (which is final image's line 1, 3, 5, 7, ..., 477, and 479.)
Even field will be CCD line2+3, line 4+5, etc., forming the second field with only half of the vertical output (which is final image's line 2, 4, 6, 8, ..., 478, and 480.)
In long exposure mode, (say the total integration time is 2.1 sec), the first field time will be 1.05 second, followed by the even field of 1.05 second, in alternating manner.
This mode emphasizes on "the flow of motion", which is what video is
Then what is the non-binning mode of such video CCD readout? (Some call it 1x1 bin, which means no binning. Such an awkward way of saying no action is done such that a fabricate operation name is given.
There is no neighboring line charge summing at all.
This is called the frame integration mode. This is good when spatial resolution is more preferred than showing the "motion". E.g., shooting long exposure astro objects.
Each CCD line has its full integration time in entire duration dedicated gathering photons, uninterrupted.
