One other question for Andrey/someone else is: - How much time elapses between when the first and last row are read-out?
from looking at the datasheet, it says that the maximum datarate is 96Mp/s, which would mean that for full resolution, the time gap would be at least 0.052488 seconds. - is the sensor being run at the full 96MHz clock rate? Is that time gap number correct? also, - How does the subsampling mode effect this. If we put the sensor in binning/skipping mode, and downsample by 4x, ideally, this would mean that there it takes 0.0032 seconds to read out a frame. thanks! -=Abe On Sun, Nov 28, 2010 at 3:34 PM, Abe Bachrach <[email protected]> wrote: > Thanks for the response.... > > From talking to Andrey and Olga on the phone, it sounds like no one at > elphel would have the time to tackle something like this themselves, so we'd > have to look to the broader community. > > > The type of sensor that we would be interested in is much lower resolution > than the kodak CCD that they developed... > > something like this: > http://www.aptina.com/products/image_sensors/mt9v022ia7atm/#overview > or > http://www.aptina.com/products/image_sensors/mt9v032c12stc/#overview > look good to me, and would hopefully not be too different from the current > sensor: > http://www.aptina.com/products/image_sensors/mt9p031i12stc/#overview > > basically, looking for something that has a global shutter, and a > resolution of 640x480 or possibly 1.3Mpixel. > a camera like one of these: > http://www.ptgrey.com/products/fireflymv/index.asp > http://www.ptgrey.com/products/chameleon/index.asp > combined with an FPGA to do image processing is what we're looking for. > > thanks! > -=Abe > > On Sat, Nov 27, 2010 at 8:38 AM, Sebastian Pichelhofer < > [email protected]> wrote: > >> Current Elphel 353 camera only has the rolling shutter option, there >> is Elphel 363 as well that uses a high resolution, large scale Kodak >> CCD but these sensors are rather expensive (~3000$) and only deliver a >> rather low framerate (3-5fps if I remember correctly).
