摘要： 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.

摘要： To realize a technique for calculating a positional relationship between a target coordinate axis fixed with respect to a detection target and a reference coordinate axis defined independently of motion and the like of the detection target, a first and a second linear magnetic fields in known directions on the reference coordinate axis are generated and a direction of the first and the second linear magnetic fields on the target coordinate axis are detected by a magnetic field sensor installed in an capsule endoscope (2), which is the detection target. By comparing the directions, which are detected by the magnetic field sensor, of the first and the second linear magnetic fields on the target coordinate axis and the known directions of the first and the second linear magnetic fields on the reference coordinate axis, a deviation of the direction of the target coordinate axis with respect to the reference coordinate axis is detected. Further, a positional relationship of an origin of the target coordinate axis with respect to an origin of the reference coordinate axis is calculated by generating diffuse magnetic field, other than the first and the second magnetic fields, whose strength decreases corresponding to a distance.

摘要： A vehicle driving assist apparatus for guiding a vehicle to a target position is provided. A basic path that changes the deflection angle θ to 0 is determined, and is subjected to similarity transformation. On the basis of the similarity-transformed path, a path factoring in transition from the initial steering angle is set. Then, a correction is made such that the area in the running distance-curvature graph regarding this path becomes equal to a corresponding area regarding the basic path, thereby setting a corrected path. The corrected path is similarity-transformed, and then is re-corrected in accordance with transition from the initial steering angle. Thus, a final target path is obtained.

摘要： A card records data as an optically readable code. A non-interference area is provided around the code to inhibit presence of only an interference image having an attribute causing an error during reading of the code. The code reader's CPU provides a code detection area to be used when a restoration section detects a code image from an image pickup area as a frame image stored in memory. This code detection area is determined based on an alignment error between the image pickup element and the code, and a specification of the code. The alignment error may result from the bottom of a slit which specifies a positional relationship between the code and the image pickup element to pick up the code.
