Abstract:
An image sensor pixel for use in a high dynamic range image sensor includes a first photodiode and a second photodiode. The first photodiode include a first doped region, a first lightly doped region, and a first highly doped region disposed between the first doped region and the first lightly doped region. The second photodiode has a second full well capacity substantially equal to a first full well capacity of the first photodiode. The second photodiode includes a second doped region, a second lightly doped region, and a second highly doped region disposed between the second doped region and the second lightly doped region. The first photodiode can be used to for measuring low light and the second photodiode can be used for measuring bright light.
