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 of intensity exhibits various undesired artifacts: noise amplification, intensity saturation, and loss of resolution.In Multi-Tools 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 Tank the image sensor or additional frame-memory; it needs only two line-memories in 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.
