Problems solved by technology

[0004] However, the amount of charge that can be accumulated per pixel in an image sensor having such a high pixel density is reduced, so that there is a problem that the amount of noise included in the signal from each pixel is relatively large
[0010] However, in this configuration, there is a problem that if noise is included in the selected representative pixel itself, the noise reduction effect considerably deteriorates

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.

Description

technical field [0001] The present disclosure relates to an image processing apparatus, an imaging apparatus, an image processing method, and a program. More particularly, the present disclosure relates to an image processing apparatus, imaging apparatus, image processing method, and program for performing image correction, such as reducing noise included in an image. Background technique [0002] Image sensors such as CCD sensors or CMOS (Complementary Metal Oxide Semiconductor) used in video cameras or still cameras accumulate charges based on the amount of incident light and perform photoelectric conversion for outputting electrical signals corresponding to the accumulated charges. In such an image sensor, a filter for individually accumulating a signal corresponding to light of a specific wavelength, ie, a specific color, is installed with respect to each pixel unit. For example, filters with Bayer arrays configured according to the respective colors of red, green and b...
