High Dynamic Range Image Sensors
30 Oct 19
An image sensor comprises a first photodiode and a second photodiode having a smaller full-well capacitance than the first photodiode, wherein the second photodiode is adjacent to the first photodiode; a first micro-lens is disposed above the first photodiode and on an illuminated side of the image sensor; a second micro-lens is disposed above the second photodiode and on the illuminated side of the image sensor; and a coating layer disposed on both the first and second micro-lens, wherein the coating layer forms a flat top surface on the second micro-lens and a conformal coating layer on the first micro-lens.

Utility
Image Demosaicer and Method
16 Oct 19
A method for demosaicing a raw image includes: (1) horizontally-interpolating a green channel formed of primary pixel-values Bg(x,y)g to yield a horizontally-interpolated green channel that includes both Bg(x,y)g and non-primary pixel-values Igh(x,y)r,b; (2) modifying each Igh(x,y)r,b, by horizontally-neighboring pixel-values, to yield a refined horizontally-interpolated green channel; (3) vertically-interpolating the green channel to yield a vertically-interpolated green channel that includes pixel-values Igv(x,y)r,b; (4) modifying each Igv(x,y)r,b by vertically-neighboring pixel-values, to yield a refined vertically-interpolated green channel; (5) generating a full-resolution green channel from the refined interpolated green channels and gradients thereof; (6) generating a full-resolution red channel by determining red pixel-values from a local-red mean value of neighboring pixel-values and the full-resolution green channel; (7) generating a full-resolution blue channel by determining pixel-values from a local-blue mean value of neighboring pixel-values and the full-resolution green channel; and (8) combining the full-resolution channels to yield a demosaiced raw image.
