Image processing apparatus and photographing apparatus
View Patent ↗An image processing apparatus includes an image processing circuit. The image processing circuit is configured by an image processing portion for performing an image process on a first image so as to generate a third image, an image composing portion for composing the first image and the third image, and an addition-ratio calculating portion for calculating a degree of composition of a composing process between the first image and the third image by the image composing portion based on a difference signal from a difference calculating portion.
1. An imaging apparatus, comprising:
an imager which captures a target scene including a plurality of objects in such a manner that a same object comes into focus and a depth of field is different, so as to acquire a first image signal and a second image signal representing two scene images;
an image creator which creates a third image signal by subjecting the first image signal to a process for reducing a level of the first image signal; and
a composite image creator which creates a composite image signal by adding the first image signal to the third image signal in such a manner that a ratio of the third image signal to the first image signal is increased as a difference of a high frequency component between the first image signal and the second image signal increase.
2. The imaging apparatus according to claim 1 , wherein said image creator performs a blurring process on the first image signal.
3. The imaging apparatus according to claim 1 , wherein said composite image creator adds the first image signal to the third image signal in such a manner that a ratio of the third image signal to the first image signal is increased as a difference of a high frequency component in each pixel between the first image signal and the third image signal increases.
4. An imaging apparatus, comprising:
an imager which captures a target scene including a specific object and a background in such a manner that a focus position is different, so as to acquire a first image signal and a second image signal representing two scene images;
an image creator which creates a third image signal in which a blurring process is performed on the background appearing in the first image of signal of the target scene, or a degree of blurring of the background appearing in the first image signal of the target scene is emphasized, based on a difference between the first image signal and the second image signal, wherein said image creator performs the blurring process in such a manner that the degree of blurring is increased as the difference increases, or emphasizes the degree of blurring as the difference increases.
