Image processing apparatus and image processing method, and program

An image processing method of executing pixel value compensation in an image processing device, wherein a signal processing unit of the image processing device performs:

• inputting image data in an RGBW arrangement that has each color pixel of R, G, and B and a white (W) pixel that passes through almost all wavelength light of each wavelength of the R, G, and B;
• interpolating the W pixel at a position of an attention pixel that is a compensation target, and at a position of a reference pixel which has the same color as the attention pixel within a reference area, in a pixel value compensation processing of a color pixel;
• calculating smoothing weight based on each pixel value of the interpolation W pixel;
• and
• calculating a compensation pixel value of the attention pixel by executing smoothing processing to which the calculated smoothing weight is applied.

A program for executing pixel value compensation in an image processing apparatus, which causes a signal processing unit of the image processing apparatus to perform:

• inputting image data in an RGBW arrangement that has each color pixel of R, G, and B and a white (W) pixel that passes through almost all wavelength light of each wavelength of the R, G, and B;
• interpolating the W pixel at a position of an attention pixel that is a compensation target, and at a position of a reference pixel which has the same color as the attention pixel within a reference area, in a pixel value compensation processing of a color pixel;
• calculating smoothing weight based on each pixel value of the interpolation W pixel;
• and
• calculating a compensation pixel value of the attention pixel by executing smoothing processing to which the calculated smoothing weight is applied.
