Zusammenfassung: | An image sensor may have an array of image sensor pixels arranged in unit pixel cells each having at least one modified clear image pixel. Each modified clear image pixel may include a modified clear color filter element formed from a transparent material such as an oxide material that is modified with a colored pigment or colored dye such as yellow pigment. Each unit pixel cell may include one or more color pixels of other colors such as red pixels, blue pixels, and green pixels. Image signals such as yellow image signals from the modified clear pixels may be processed along with other color image signals such as red image signals and blue image signals to generate standard red, green, and blue image data. Image processing operations may include chroma demosaicing or point filtering of the image signals from the modified clear image pixels. |
