Pixel Scan company was founded by Professor Orly Yadid-Pecht from Israeli Ben-Gurion University. The company proposes Quantum Efficiency Spectra Reshaping (QESR) technology that enhances CIS performance. The QESR hardware block takes sensor's output and does some magic in Bayer domain that relies on "Patented Technology that Reshapes Image Sensor’s QE Spectra, while reducing its Inherent Color CrossTalk (CTK)
The signal is “rearranged” such that the photocarriers captured by the "wrong" pixels are "restored" to the pixel they initially originated from without signal loss and additive noise."
The net result of QESR algorithm is 10% low-light sensitivity improvement and more:
