摘要： A fault tolerant display displays safety information on a display shared with an infotainment system even if the processor or software of the infotainment system is unresponsive. The display can be a streaming video from a rear view camera mounted on a vehicle. The safety displayed can be triggered by placing the vehicle in reverse. Failure of the infotainment software and/or processor can be detected by a policy enforcing module that switches to a backup display that streams video directly from the camera in the event of failure of the infotainment processor.

摘要： An image processing apparatus includes a flatness detector, a difference calculation section, a noise level detector, and a motion detector. The flatness detector detects a flat region where pixel values of pixels on a first image are flat, based on variances of the pixel values of the pixels constituting the first image inputted. The difference calculation section calculates a difference between the pixel values of the pixels corresponding to the first image and a second image which continues before or after the first image. The noise level detector detects a noise level indicating a statistic noise amount of noise generated in each pixel constituting the first image based on the variances of the difference. The motion detector detects at least one of a still region indicating a region where an object on the first image is still and a motion region indicating a region where the object is moving.

摘要： A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.

摘要： An up-converter (7) performs up-conversion on frame images in a video signal. A pseudo-noise generation circuit (9) generates a pseudo-noise signal, and an adder (10) composites the pseudo-noise signal with the up-converted video signal. As a result, noise having the same resolution as the up-converted frame images (1920 vertical pixels by 1080 horizontal lines) is distributed in the composited frame images, and each piece of noise has a characteristic approximating a characteristic (crest value, amount, or frequency) of noise included in the pre-conversion video signal.

摘要： A signal processing device (201) includes noise reduction units (101), cascade-connected to each other, each of which includes: a signal selection section (31) for selecting a representative value from sampled signals obtained from an input signal by sampling a target signal and signals which are away from the target signal by given intervals; a voltage determination section (51), for determining which of a determined representative value and a voltage of the target signal is larger; and a signal output section (61) for increasing or decreasing the voltage of the target signal depending on a result of the determining and outputs the target signal as the output signal. A combination of intervals between the target signal and a the signals excluding the target signal vary from noise reduction unit (101) to noise reduction unit (101). A noise reduction unit on a more upstream side has a larger maximum value of the intervals.
