Abstract:
1. An imaging capturing device comprising: a user interface being configured to facilitate an image capturing process; an input being configured to receive a user input, the user input being a command for capturing an image; an image sensor being configured to capture an image; an optical device being positioned to provide a light to form an image on the image sensor; a processor being configured to process images; wherein the image sensor comprises: an n-type substrate, the n-type substrate including a first width and a first thickness; a p-type epitaxy layer overlying the n-type substrate, the p-type epitaxy layer including a second width and a second thickness, the second width including an adjustable depletion region between the n-type substrate and the p-type epitaxy layer, the adjustable depletion region being associated with one or more characteristics of a colored light; an n-type layer overlying the p-type layer, the n-type layer being associated with a third width and a third thickness; a pn junction formed between the p-type layer and the n-type layer; and a control circuit being coupled to a CMOS image sensing pixel.
