Low-Light Image Enhancement Using Adaptive Digital Pixel Binning

Blog Article

This paper presents an image enhancement algorithm for low-light scenes in an environment with insufficient illumination.Simple amplification Collectors of intensity exhibits various undesired artifacts: noise amplification, intensity saturation, and loss of resolution.In order to enhance low-light images without undesired artifacts, a novel digital binning algorithm is proposed that considers brightness, context, noise level, and anti-saturation of a local region in the image.

The proposed algorithm does not require any modification of the image sensor or additional frame-memory; it needs only two line-memories in Thick Socks the image signal processor (ISP).Since the proposed algorithm does not use an iterative computation, it can be easily embedded in an existing digital camera ISP pipeline containing a high-resolution image sensor.
