1. An image processing apparatus comprising: an image sensor including a plurality of first pixels configured to detect an image and a plurality of second pixels configured to detect a different type of signals than the plurality of first pixels, the image sensor being configured to read out values from at least one of the plurality of second pixels and at least one the plurality of first pixels, based on a predetermined rule, and to output a first sampling image, based on the read out values; and an image processor configured to restore values of the at least one of the plurality of second pixels to be image pixel values for locations of the at least one of the plurality of second pixels included in the first sampling image, to output a restored image based on the restored values, to perform binning on pixels of the restored image using a predetermined method, and to output a reduced resolution image with a resolution reduced at a predetermined rate from the restored image, based on the binning.
