"Oko" sub-standard Cine Camera/Projector
1912
'Oko' sub-standard cine camera/projector by Proszynski, patented 1912. Also samples of film and carrying box.
The OKO camera projector was invented by Kasimir Proszynski in 1912 and first demonstrated in 1914. His unusual design used a strip of film 12cm wide which was perforated on both edges. The camera exposed horizontal rows of 15 pictures 7 x 5mm in size, across the film, which then moved on a step, taking a futher row of pictures back in the other direction. For projection, the same mechansim with the addition of a special electric lamp was used. OKO is Polish for eye.
