These are the patents:
7,830,967: Applying a gamma correction before compression
8,174,560: Above with a transformation to take a delta between green and the red and blue channels to enhance compressability. Claims are extremely vague on this one.
9,245,314: Lossy compression prior to moving sensor data into memory
9,436,976: Just looks like a combination of the three previous patents
Kodak had prior art on a lot of this for their satellite image processing which isn't technically video but the data rates are in the same realm.
- NonNefarious 4y agoAll of which are patents on MATH, which is supposed to be unpatentable. Talk about bullshit.
- alok-g 4y agoNote: I haven't read these patents. Mathematics by itself is not patentable, but its usage certainly is. (In fact, if that were not the case, perhaps nothing would be patentable given how mathematical nature is.)
