You mean Panasonic patents not Canon? There are numerous patent suits by everyone and their brother. Most are from Nokia suing others. Panasonic may have used it in cameras but it is not the same in the phones and they do not even know how the actual programmers did it. They assume it is the same.
It will be great for camera enthusiasts. They have the 808 overseas now with 41 mp. It was sort of modeled after N8. I bought one for worker overseas and she is 19. The phone looks like a camera. It does not have the sleek look of the 920's because of the lens. I had it shipped to me and I shipped it to her and it took forever. I could not get cooperation from the Microsoft people in her country on to give her one. At first I thought they shipped me a phone. I will be honest, she said she loves the phone but the look was too camerish and not cool and lean. The new lumia version is going to be more lumia like not like a camera which quite frankly was a turn off. The software is a whole different nut to crack. Nokia says they use several sensor pixels to build a single image pixel. That is the reverse of interpolation. The current Lumia 920 with pureview software is similar. The large lens is 7728x4354 in the 41 mp. Nokia's sensor is a rare multi-aspect ratio type. The two supported frame aspect ratios use the maximum number of vertical or horizontal pixels; for the 4:3 format all the vertical pixels are used and in the wide screen format all the horizontal pixels are used. So the current Lumias pictures are good very good. You are right, a 41 mp camera will be an incredible boost in sales and may be the most popular phone ever if the look is tweeked. I am long on nok and msft and do not know if this will happen or not.
The great part of all of these announcements demonstrates the Nokia is on the move and very innovative. I understand the camera is a left over from their failed phones over the past few years. Reinventing themselves -very impressive!
