Caeleste Proposes "True Charge Domain Binning"
Caeleste patents a true charge domain binning method by making a number of pixels “non-collecting”. The photo charge that is not collected by these pixels is then collected by drift or diffusion by the other pixels in the kernel.

Nice idea !
ReplyDeleteTwo questions: 1) is there a possible image lag, since the charge captured by floating PD will be released with a logarithmic rate; 2) charge captured by the floating PD will be in a surface anti-blooming state, so is there a risk of non-linearity ?
Thanks !
actually we wondered ourselves. The "lag" problem is relaxed by enforcing a potential instead of letting it float. And indeed, lag must be avoided as lag often has non-linearity as side effect.
