Abstract

An image processor including an object extracting device extracting an object region from original image data; an object separating device separating the object region from the other region; a first filter subjecting the object region to out-of-focus filtering processing to output first image data; a second filter subjecting the other region to out-of-focus filtering processing to output second image data; an image synthesizing device synthesizing the first and second image data; a displaying device displaying the synthesized image data and original image data; a region splitting device splitting the synthesized image data into plural regions; a high-frequency component obtaining device obtaining high-frequency components in each of the plural regions; a high-frequency component analyzing device analyzing the high-frequency components; and a zooming device zooming a region among the plural regions having higher frequency components.

Claims

1. An image processor comprising;

an object extracting device configured to extract an object region from original image data;

an object separating device configured to separate the extracted object region from the other region;

a first filtering device configured to subject the object region to an out-of-focus filtering processing and to output first image data;

a second filtering device configured to subject the other region to an out-of-focus filtering processing and to output second image data;

an image synthesizing device configured to synthesize the first image data and the second image data;

a displaying device configured to display the synthesized image data and the original image data, which are not subjected to the out-of-focus filtering processing;

a region splitting device configured to split the synthesized image data into plural regions;

a high-frequency component obtaining device configured to obtain high-frequency components in each of the plural regions;

a high-frequency component analyzing device configured to analyze the high-frequency components thus obtained by the region splitting device; and

a zooming device configured to zoom a region among the plural regions, which has higher frequency components than the other regions of the plural regions.

2. The image processor according to claim 1, wherein the region splitting device splits a boundary zone between the object region and the other region of the synthesized image data into plural regions.

3. The image processor according to claim 1, wherein the region splitting device splits the other region of the synthesized image data into plural regions.

4. The image processor according to claim 1, further comprising:

the high-frequency component obtaining device obtains high-frequency components in a portion of the other region when the high-frequency component analyzing device determines that no high-frequency components are obtained.

5. The image processor according to claim 1, further comprising:

the high-frequency component obtaining device obtains high-frequency components in a portion of the object region when the high-frequency component analyzing device determines that no high-frequency components are obtained.

6. A digital camera comprising:

a lens;

a shutter;

an image pick-up device configured to receive a light image formed by the lens and the shutter; and

the image processor according to claim 1 configured to process image data of the light image.

7. A method for processing image data, comprising:

extracting an object region from original image data;

separating the extracted object region from the other region;

subjecting the object region to an out-of-focus filtering processing to output first image data;

subjecting the other region to an out-of-focus filtering processing to output second image data;

synthesizing the first image data and the second image data;

subjecting the original image data to an out-of-focus filtering processing;

splitting the synthesized image data into plural regions;

obtaining high-frequency components in each of the plural regions;

analyzing the high-frequency components; and

displaying the synthesized image data and the original image data, which are not subjected to the out-of-focus filtering processing, while zooming a region among the plural regions, which has higher frequency components than the other regions of the plural regions.
