Abstract
A new electronic imaging system is achieved. The system comprises a sensor having a first color region, a second color region, and a third color region. A prism system comprises a first prism having a first index of refraction and overlying the first color region. The first prism directs incident light of the first color to the first color region of the sensor. A second prism has a second index of refraction and overlies the second color region. The second prism directs incident light of the second color to the second color region of the sensor. A third prism has a third index of refraction and overlies the third color region. The third prism directs incident light of the third color to the third color region of the sensor.
Claims25
An electronic imaging system comprising:
- a sensor having a first color region, a second color region, and a third color region;
- and
- a prism system comprising:
- a first prism having a first index of refraction and overlying said first color region wherein said first prism directs incident light of said first color to said first color region of said sensor;
- a second prism having a second index of refraction and overlying said second color region wherein said second prism directs incident light of said second color to said second color region of said sensor;
- and
- a third prism having a third index of refraction and overlying said third color region wherein said third prism directs incident light of said third color to said third color region of said sensor.
An electronic imaging system comprising:
- a sensor having a first color region, a second color region, and a third color region wherein said first, second, and third color regions comprise red, green, and blue;
- and
- a prism system comprising:
- a first prism having a first index of refraction and overlying said first color region wherein said first prism directs incident light of said first color to said first color region of said sensor;
- a second prism having a second index of refraction and overlying said second color region wherein said second prism directs incident light of said second color to said second color region of said sensor;
- and
- a third prism having a third index of refraction and overlying said third color region wherein said third prism directs incident light of said third color to said third color region of said sensor.
A method to form an electronic imaging system comprising:
- forming a plurality of light sensors on a semiconductor wafer;
- and
- forming a plurality of prisms overlying said light sensors wherein each said prism overlies one said light sensors, wherein each said prism has an index of refraction, wherein each said prism has a height, and wherein each said prism directs incident light of a color to said light sensor underlying said prism.
