Abstract
An electronic imaging apparatus capable of obtaining high image quality that serves for printed photographs, e.g. DTP and posters. The apparatus has an image-forming optical system (1), a solid-state image pickup device (3), a signal processing device (4), and a sensor driving circuit (5). The image-forming optical system (1) includes a diffraction lens for correcting chromatic aberrations. The signal processing device (4) includes an image processing device for removing flare components due to unwanted orders of diffracted light produced by a diffraction surface. The image processing device obtains a flare component by performing the convolution of the point image energy intensity distribution of each unwanted order of diffracted light with the energy intensity distribution of an image signal, and subtracts the flare component from the image signal to obtain a corrected image signal.
