NO ACTIVITY = TAKE SNAP!...anyone?
What could be done, in theory, is get the motion vectors, then do some intelligent image reconstruction based on that. You don't need too much memory for it, so long as you can read and write in the raw buffer. Of course, it might take forever to do on a low speed ARM processor, and it's not easy to implement, but it should be possible.
Quote from: brainwash on 24 / June / 2008, 11:21:13I think on the cheaper Nikon cameras there is a mode which retains the sharpest picture. So you keep the shutter pressed, it works like burst mode and the camera retains what it thinks is the sharpest picture.Yep, and I think this can already be found in the feature requests section somewhere... at least it was discussed a while back.

Maybe I am wrong, but I think that the motion vector might be accessible from the camera orientation sensor?I am not sure how it operates, for example does it just return 4 orientation values? Or does it return some larger range, such as an integer/float?Is it 2d or 3d? And how fast is that updated?If the sensor returns a large range of values, and if it is 3D (although 2d should work to some extent as well), and if it is updated fast enough, then this data could be saved along with the picture (perhaps in a text or binary file), then have a PC program that enhances the image. Doing it on the camera might be too slow and too difficult.
Another idea is to get the data from the IS sensor. This should be much better data, but only limited to the IS cameras.
There is a Photoshop plug in (forgot the name) that can do some image reconstruction if the motion vector is known (you enter it manually). But if you know multiple motion vectors (for example, 1 vector per milisecond), and if someone builds a program to use that data, I think the image blur resulted from camera shake could be almost entirely eliminated.
But then again, if you have an IS sensor, then your camera is already stabilizing the video optically (and without cropping, as it actually moves the lens)... am I missing something?
