Image Apparatus and Image Processing Method
First Claim
1. An imaging apparatus, comprising:
- an imaging element capturing a diffused image of an object passed through at least an optical system and an optical wavefront modulation element,a signal processing portion including a converting means for generating a diffusion-free image signal from a diffused image signal from the imaging element and performing predetermined processing on the image signal from the imaging element, anda generating means for combining the image before the processing of the signal processing portion and the image after the processing to form a new image.

Abstract
An imaging apparatus and an image processing method able to simplify an optical system, able to reduce costs, able to obtain an image blurred only in a background by a single imaging operation, and able to obtain a restored images with little influence of noise, wherein a signal processing portion formed by an image processing device 140 etc. has a generation function of generating a diffusion-free image signal from a diffused image signal of an object from an imaging element 120 and performing other predetermined signal processing on the diffused image signal and combining an image before the processing of this signal processing portion and an image after the processing to form a new image, and, in this generation function, generates a plurality of images in a background region by blurred image processing combines them with a focused image of an object region including a main object after the processing to generate a new image and records the image before the signal processing, the restoration image after the processing, and the combined new image in a memory buffer etc.
