Ultra-high speed readout of a sparse image.
The first imager to realize ultra-high speed sparse readout of a megapixel small-pixel (8µm) array, by copying a “SLICE” of the pixel array data into a processor array. The below 1Mpixel prototype is able to output about 8000 frames per second.

Comparing 4 HDR methods
Here we use a pretty strict definition of “High Dynamic Range”: It must at the same time comply with: 1) knee-less fully linear 2) allowing RWI synchronous shutter and 3) complete CDS. 3 methods are actually Caeleste patents, the 4th is the historical “overflow barrier” method

Record for lowest read noise in CIS
CMOS pixels is pushed a little bit further again, as reported in our 3rd IISW paper. The value of 0.34 (sic) electrons RMS is obtained at the cost of accumulation-inversion cycling, severe oversampling and cooling down to -40°C.
