  • Pixel array, image sensor having the pixel array and method for removing flicker noise of the image sensor
    Publication number: 20040080630
    Abstract: There are provided a pixel array capable of detecting and removing a flicker noise, an image sensor employing the pixel array and an automatic flicker noise detecting method capable of effectively detecting and removing the flicker noise of the image sensor. For the purpose, a pixel array of an image sensor includes a pixel group, having N×M number of unit pixels, for detecting an image signal, N and M being integers, and a pixel column, allocated along a row direction of the pixel group, for detecting an average frequency of a corresponding pixel row to thereby detect the flicker noise.

  • Image sensor and method for fabricating the same
    Patent number: 6661046
    Abstract: A CMOS image sensor for improving a characteristic of transmittance therein is provided by forming a convex-shaped color filter pattern that acts as a micro-lens. The CMOS image sensor includes a semiconductor structure having a photodiode and a peripheral circuit, an insulating layer that is formed on the semiconductor structure and that has a trench, and a convex-shaped color filter pattern formed on the insulating layer and covering the trench.
