Abstract: A method for resolution enhancement of a still-image made by a digital imaging device. The method allows the use of high-aperture-ratio sensing arrays that produce resolution-enhancement, independent of the angle of view. Resolution-enhancement is achieved using a multiple-exposure technique of a sub-pixel overtap in conjunction with a whole-pixel shift. The method suppresses color-aliasing in a multiple-exposure native-resolution mode and enables the use of a single camera for single-exposure and multiple-exposure modes.

Abstract: Setting so as to substantially minimize the aliasing distortion component at zero in spatial frequencies and at a Nyquist frequency is one of the examples of the present invention. When the setting is used, an image can be provided and displayed at a resolution higher than the number of physical pixels in the imaging apparatus and display apparatus.
