Abstract
Disclosed are a camera, an image sensor thereof, and a driving method thereof. An image sensor converts an incident light into an electrical image signal. The image sensor outputs the converted electrical image signal by removing noise from the electrical image signal. An image processing unit processes the output image signal to generate screen image data. The image sensor effectively removes noise, thereby improving the optical precision of the camera.
Claims19
An image sensor comprising:
- an image detecting unit for converting an incident light into an electrical image signal;
- and
- a noise filter for removing noise from the electrical image signal,
- wherein the image sensor is assembled with a lens unit for receiving the incident light and comprising a diffractive optical element (DOE),
- wherein the noise is caused as the light is diffracted in the diffractive optical element.
