ABSTRACT:
An apparatus and a method for reducing noise from an image sensor are provided. The apparatus includes a noise-estimation unit which estimates a noise level representing an image frame expressed as a component in a color space, a filter-strength-calculation unit which determines filter strength based on the estimated noise level, and a filter-application unit which filters pixels constituting the image frame according to the determined filter strength.
