Panasonic in Japan applied for a patent for a technology called the rolling shutter effect for cmos image sensors to reduce the. In place of the reading of pixelrijen made the reading slow and parallel.

An important difference between the image sensors based on ccd and cmos technology is the possibility when the former sensor type, the pixels are simultaneously read out, while with cmos image sensors the pixels row after row are read out. In moving pictures in the last case, the rolling shutter effect to occur.

This is good to see as the camera quickly to the left and to the right is rotated. Straight lines of for example, lamp posts or buildings will appear on the recording bent, because the lower pixelrijen at a slightly later time to be read than the rows above it. Especially when video is the rolling shutter effect is visible.

The images on Egami, the patent of Panasonic, filed on January 8, 2010, is to see that not only different pixelrijen at the same time be read, but also that the reading is not-sequentially takes place. The ‘jello’effect can therefore be reduced. Because of the pairwise read-out seems to go to an image sensor with two uitleeskanalen.
