Imaging with an ultra-high-speed video camera operating at 20 Mfps for 300 kpixels

An image sensor with 300 kpixels operating at 20 Mfps is developed. Pixels on odd-number and even-number columns can be independently operated. The highest frame rate is 40 Mfps when a time shift of a half of the shortest frame interval is introduced to the operation of the odd and even pixel column...
