Panasonic Announces Patent of HDR Sensor Technology to Individually Adjust Pixel Exposure Time per Line

Panasonic recently announced a patent for an HDR sensor technology, which was filed on November 19, 2010 and publicly released on June 14, 2012. At present, the patent still exists only in the patent data and has no application.

It is reported that this patented technology can make the exposure time of each row of pixels individually adjustable, mainly based on the change of the scene being shot. While adjusting the exposure time, the sensor will fully guarantee the resolution. Where is the application of this patent?

Imagine that you want to take a picture of the landscape, but whether it is a brighter sky or a darker part of the foreground, the same photo will have the same exposure time. This obviously will regret many photographers who pursue perfection. Panasonic's HDR sensor technology, on the other hand, will shorten the exposure time for pixels that image brighter parts, and will prolong the exposure time for pixels in the darker parts of the foreground. In this way you will get a photo with both the highlight and the dark part exposed.
