Abstract

The invention relates to an image processing device, an image processing method and a program. The image processing device includes a data conversion processing unit that receives an input of an RGBW array image and generates an RGB array image as an output image. The data conversion processing unit includes a pixel interpolation unit that calculates interpolated pixel values corresponding to an array of the RGB array image by performing a pixel interpolation process on the RGBW array image, a purple fringe detection unit that detects whether each pixel is a purple fringe pixel by analyzing the RGBW array image, a corrected value calculation unit that calculates corrected pixel values by correcting pixel values of the purple fringe pixels, and a blend processing unit that calculates constituent pixel values RGB of the output image by performing a blend process of blending the interpolated pixel values calculated by the pixel interpolation unit with the corrected pixel values calculated by the corrected value calculation unit.

Description

technical field [0001] The present disclosure relates to an image processing device, an image processing method, and a program, and more particularly, to an image processing device, an image processing method, and a program capable of performing correction processing for false colors generated in images captured by a camera. Background technique [0002] In the image captured by the camera, the problem of aberration of the camera lens appears in some cases. Specifically, for example, chromatic aberration is a kind of aberration caused by the influence of lens aberration. When the refractive index of light in an imaging lens of a camera differs according to wavelength, chromatic aberration occurs, and false colors are caused on an imaging surface. [0003] Known as representative examples of chromatic aberrations: For example, axial chromatic aberration in which chromatic blur occurs because the focus position on the optical axis differs depending on the wavelength, and colo...
