## Abstract

An image processing method to obtain a high sense of depth or high stereoscopic effect for an image and a display device utilizing the method are provided. Image data of an image is separated into image data of a plurality of objects and a background. A feature amount is obtained from the image data of each object, so that the objects are identified. The relative distance between viewer's eye and any of the objects is determined by the data of the sizes of the objects in the image and the sizes of the objects stored in the database. The image data of each object is processed so that an object with a shorter relative distance is enlarged. The image data of each object after image processing is combined with the image data of the background, so that a sense of depth or stereoscopic effect of an image is increased.

## Claims

### Claim 1

An image processing method comprising the steps of:
separating first image data of an image into image data of a first object, image data of a second object, and image data of background;
obtaining data of a size of the first object and a size of the second object;
processing the image data of the first object to obtain an enlarged image data of the first object;
processing the image data of the second object to obtain an enlarged image data of the second object; and
combining the enlarged image data of the first object and the enlarged image data of the second object with the image data of the background to generate second image data,
wherein the size of the first object is enlarged in the second image data,
wherein the size of the second object is enlarged in the second image data, and
wherein a magnification rate of the first object is higher than a magnification rate of the second object.

### Claim 2 (depends on 1)

The image processing method according to claim 1, further comprising the step of obtaining a feature amount with data stored in a database.

### Claim 3 (depends on 1)

The image processing method according to claim 1, wherein the processing step and the combination step are carried on so that a sense of depth or stereoscopic effect of an image formed from the second image data is increased compared to a sense of depth or stereoscopic effect of an image formed from the first image data.

### Claim 4

An image processing method comprising the steps of:
separating first image data of an image into image data of a first object, image data of a second object, and image data of background;
obtaining data of the first object and data of the second object;
processing the image data of the first object to change a degree of an exaggeration of an outline of the first object;
processing the image data of the second object to change a degree of an exaggeration of an outline of the second object; and
combining the image data of the first object after the processing the image data of the first object and the image data of the second object after the processing the image data of the second object with the image data of the background to generate second image data,
wherein the degree of the exaggeration of the outline of the first object is larger than the degree of the exaggeration of the outline of the second object.

### Claim 5 (depends on 4)

The image processing method according to claim 4, further comprising the step of obtaining a feature amount with data stored in a database.

### Claim 6 (depends on 4)

The image processing method according to claim 4, wherein the processing step and the combination step are carried on so that a sense of depth or stereoscopic effect of an image formed from the second image data is increased compared to a sense of depth or stereoscopic effect of an image formed from the first image data.

### Claim 7

An image processing method comprising the steps of:
extracting image data of a first object and a second object from first image data;
obtaining data of the first object and the second object;
processing the image data of the first object and the second object to change a degree of an exaggeration of an outline of one of the first object and the second object; and change a size of the one of the first object and the second object; and
combining the image data of the first object and the second object after the processing with the image data of a background of the first image data to generate second image data.

### Claim 8 (depends on 7)

The image processing method according to claim 7, further comprising the step of obtaining a feature amount with data stored in a database.

### Claim 9 (depends on 7)

The image processing method according to claim 7, further comprising the step of determining a front-back relation between the first object and the second object.

### Claim 10 (depends on 7)

The image processing method according to claim 7, wherein the processing step and the combination step are carried on so that a sense of depth or stereoscopic effect of an image formed from the second image data is increased compared to a sense of depth or stereoscopic effect of an image formed from the first image data.

### Claim 11 (depends on 7)

The image processing method according to claim 7, wherein the one of the first object and the second object is enlarged compared to the other of the first object and the second object.

### Claim 12 (depends on 7)

The image processing method according to claim 7, wherein the outline of the one of the first object and the second object which is determined to be more on the front side of the image are reinforced compared to the outline of the other of the first object and the second object which is determined to be more on a back side of the image.

### Claim 13 (depends on 7)

The image processing method according to claim 7, wherein a distance between a vanishing point and a center point of the one of the first object and the second object which is determined to be more on the front side of the image is lengthened compared to a distance between the vanishing point and a center point of the other of the first object and the second object which is determined to be more on a back side of the image.
