Abstract
A displaying and imaging apparatus includes a displaying and imaging panel, a generating unit for generating a difference image between a reflection light using image and a shadow image obtained from the displaying and imaging panel, and an image processing unit for obtaining information of at least one of position, shape, and size of the adjacent object on the basis of the difference image. The generating unit generates, on the basis of a plurality of images obtained at timings different from each other, which are one of the reflection light using image or the shadow image, one interpolation image corresponding to the one of images obtained at a timing different from those of the plurality of images, and generates the difference image by the difference between the interpolation image and the other one of the reflection light using image and the shadow image.
