24 May 2013TL;DR: In this paper, a first imaging device performs photoelectric conversion of subject light made incident through a first filter which prevents light of a predetermined wavelength band longer than a wavelength of visible light from being transmitted, and outputs a first image signal.
Abstract: PROBLEM TO BE SOLVED: To achieve both of improvement of sensitivity and improvement of color reproducibility.SOLUTION: A first imaging device performs photoelectric conversion of subject light made incident through a first filter which prevents light of a predetermined wavelength band longer than a wavelength of visible light from being transmitted, and outputs a first image signal. A second imaging device is arranged on a position different from that of the first imaging device, performs photoelectric conversion of subject light including a wavelength component of light of a predetermined wavelength band and outputs a second image signal. A correlation detection part detects correlation between the first image signal and the second image signal. A luminance signal generation part generates a luminance signal from the second image signal. A color signal generation part generates a color signal from the first image signal and/or the second image signal. A three-dimensional image generation part generates a three-dimensional image by using information on the correlation detected by the correlation detection part, the luminance signal and the color signal.

28 Feb 2013TL;DR: In this article, a representative pixel update unit is configured to, based on pixels around a position of representative pixels in a smoothed image generated based on the input image as reference pixels, execute pixel value correction of the representative pixels by applying the pixel values of the reference pixels.
Abstract: There is provided an image processing apparatus including a representative pixel calculation unit configured to select some pixels in an input image as representative pixels, a representative pixel update unit configured to update pixel values of the representative pixels, and a corrected image generation unit configured to set pixel values for pixels other than the representative pixels by applying the updated pixel values of the representative pixels. The representative pixel update unit is configured to, based on pixels around a position of the representative pixels in a smoothed image generated based on the input image as reference pixels, execute pixel value correction of the representative pixels by applying the pixel values of the reference pixels.
