Abstract: An image denoising system and method of implementing the image denoising system is described herein. Noise is decomposed within each channel into frequency bands, and sub-band noise is propagated. Denoising is then able to occur at any node in a camera pipeline after accurately predicting noise that is signal level-dependent, frequency dependent and has inter-channel correlation. A methodology is included for estimating image noise in each color channel at a sensor output based on average image level and camera noise parameters. A scheme is implemented for detecting a peak-white image level for each color channel and predicting image level values for representative colors. Based on a noise model and camera parameters, noise levels are predicted for each color channel for each color patch and these noise levels are propagated to the denoising node. A three dimentional LUT correlates signal level to noise level. Then, a denoising threshold is adaptively controlled.

Abstract: A fast accurate multi-channel frequency dependent scheme for analyzing noise in a signal processing system is described herein. Noise is decomposed within each channel into frequency bands and sub-band noise is propagated. To avoid the computational complexity of a convolution, traditional methods either assume the noise to be white, at any point in the signal processing pipeline, or they just ignore spatial operations. By assuming the noise to be white within each frequency band, it is possible to propagate any type of noise (white, colored, Gaussian, non-Gaussian and others) across a spatial transformation in a very fast and accurate manner. To demonstrate the efficacy of this technique, noise propagation is considered across various spatial operations in an image processing pipeline. Furthermore, the computational complexity is a very small fraction of the computational cost of propagating an image through a signal processing system.

Abstract: An object of the present invention is to enable clearly identifying whether a body-cavity image displayed on a display unit is based on data which is directly received by a viewer itself, or whether the body-cavity image displayed on the display unit is based on data received by another receiving device. An identification notifying unit presents different identification modes such as a capsule mark and a cable mark 41 which are sensory recognizable between the case where a body-cavity image based on body-cavity image data which a first receiving unit has received directly from a capsule endoscope is displayed, and the case where a body-cavity image 40 based on body-cavity image data which a second receiving unit has received via another receiving device is displayed. Thus, it is possible to clearly identify which receiver has received the body-cavity image data based on which the body-cavity image is displayed.
