Claim Text:
1. An imaging device, comprising: a photography optical system; a single plate-type imaging element in which a plurality of pixels including two-dimensionally arranged photoelectric conversion elements and having a different underlayer layout are repeatedly arranged in a predetermined pattern, and color filters in a predetermined color filter array are arranged on the plurality of pixels; a determination unit configured to determine that a ghost is generated when an output level of one of the plurality of pixels and an output level of the same color pixel in the vicinity of the one pixel, which is the other pixel having a different underlayer layout from the one pixel, are different within a range in which the output levels do not exceed a previously set threshold, which is based on characteristics or a usage situation of the photography optical system, and when the difference between the output level of the one pixel and the output level of the other pixel is repeatedly generated according to a repetition period of the underlayer layout; and a correction unit configured to perform correction to reduce a difference between the output level of the one pixel and the output level of the same color pixel in the vicinity when the determination unit determines that the ghost is generated, wherein the determination unit performs a determination as to whether a ghost is generated with respect to a pixel corresponding to one of the filter colors of the color filters, and when the determination unit determines that the ghost is generated with respect to the one color, the correction unit performs the correction on pixels corresponding to all filter colors of the color filters including the one color.
