Abstract
An imaging device is provided with a lens distortion correction function that requires less circuit scale and does not degrade image resolution.The imaging device having the lens distortion correction function is provided which includes a same-color interpolation unit that generates a lens distortion-corrected interpolation signal by using a same-color pixel in an image signal from an imaging element, a luminance signal generation unit that generates a luminance signal from the image signal from the imaging element, a first luminance signal generation unit and a second luminance signal generation unit that use the luminance signal generated by the luminance signal generation unit to generate a lens distortion-corrected interpolation signal, a lens distortion characteristics table data unit that holds information of coordinates after lens distortion characteristics correction in a memory, a coordinate/interpolation coefficient setting unit that individually generates interpolation coefficients for correcting lens distortion for each of the same-color interpolation unit, the first luminance interpolation unit, and the second luminance interpolation unit on the basis of information fr…
