Image processing device, image processing method, and image processing system

An image processing method for an image processing device, the method being performed by the image processing device and comprising steps of:

• estimating a defect of a pixel of interest in an image captured by a solid-state imaging device that contains a two-dimensional array of color pixels, and high-sensitivity pixels having higher sensitivity than sensitivities of the color pixels, the defect of the pixel of interest being estimated on the basis of a correlation between pixel values of the high-sensitivity pixels, and pixel values of the color pixels;
• and
• correcting the pixel of interest when it is estimated that the pixel of interest is a defective pixel.

An image processing system comprising:

• a solid-state imaging device that contains a two-dimensional array of color pixels, and high-sensitivity pixels having higher sensitivity than sensitivities of the color pixels;
• and
• an image processing device that includes a defective pixel estimation unit for estimating a defect of a pixel of interest in an image captured from the solid-state imaging device on the basis of a correlation between pixel values of the high-sensitivity pixels, and pixel values of the color pixels, and includes a defective pixel correction unit for correcting the pixel of interest when it is estimated that the pixel of interest is a defective pixel.
