摘要： A magnification chromatic aberration included in image data in a color filter array captured by an imaging device is corrected by performing a coordinate transformation with respect to each pixel in the image data. A defective pixel due to the color filter array is compensated with respect to magnification-chromatic-aberration-corrected image data.

摘要： An object detection apparatus includes a light illumination unit that emits illuminating light; an imaging unit that captures a first image of distant photographic subjects by detecting lights from the photographic subjects, captures a second image of foreign matter attached to a monitoring area by detecting the illuminating light reflected from the foreign matter, and generates an image frame; a target detection unit that detects a detection target among the distant photographic subjects based on the first image; a foreign matter detection unit that detects the foreign matter based on the second image; and an exposure amount change unit that changes an exposure amount of the imaging unit. The target detection unit detects the detection target using plural imaging frames with different exposure amounts. The foreign matter detection unit detects the foreign matter using the imaging frame other than the imaging frame with the greatest exposure amount.

摘要： An image processing apparatus includes a line buffer, an FIR filter serving as an edge enhancement filter that enhances high-frequency components of an image, and an IIR filter serving as a low-pass filter that reduces noise. The same line buffer is used by both the FIR filter and the IIR filter. According to a switching signal, switches enable the FIR filter and disable the IIR filter for a relatively low noise level while the switches enable IIR filter and disable the FIR filter for a relatively high noise level.
