## Abstract

An image processing apparatus includes an image acquiring unit, a distance acquiring unit, a painterly transformation processor, a thickness information acquiring unit, and a data generating unit. The distance acquiring unit acquires distance information for each of at least one object image included in an acquired image. The painterly transformation processor transforms each of the object image, included in the acquired image, into a painterly image. The thickness information acquiring unit acquires thickness information corresponding to the distance for each of the object image. The data generating unit generates data in which the painterly image and the thickness information are associated with each other.

## Claims

### Claim 1

An image processing apparatus comprising:
an image acquiring unit that acquires an image;
a distance acquiring unit that acquires a distance to an object for an object image included in the image acquired by the image acquiring unit;
a contour extracting unit that extracts a contour of the object image included in the image acquired by the image acquiring unit;
a painterly transformation processor that transforms the object image included in the acquired image into a painterly image, wherein the painterly transformation processor comprises a line transformation processor that transforms the extracted contour of the object image into a line having a style corresponding to the acquired distance;
a thickness information acquiring unit that acquires thickness information corresponding to the distance acquired by the distance acquiring unit for the corresponding line having the style corresponding to the acquired distance; and
a data generating unit that generates data in which the line and the thickness information are associated with each other.

### Claim 2 (depends on 1)

The image processing apparatus according to claim 1,
wherein the line transformation processor comprises a line variation transformation processor that transforms the extracted contour of the object image into a thinner line as the distance to the object is longer, and into a thicker line as the distance to the object is shorter,
wherein the thickness information acquiring unit adds information indicating a smaller thickness for a thinner line, and adds information indicating a larger thickness for a thicker line.

### Claim 3 (depends on 1)

The image processing apparatus according to claim 1, wherein the image acquiring unit comprises a communication section that receives an input of image data from an external device including a communication section.

### Claim 4 (depends on 1)

The image processing apparatus according to claim 1, wherein the image acquiring unit comprises a wireless communication section that wirelessly receives an input of image data from an external device including a wireless transmission section.

### Claim 5 (depends on 1)

The image processing apparatus according to claim 1, wherein the image acquiring unit comprises an image input section that receives an input of image data stored in a storage medium.

### Claim 6 (depends on 1)

The image processing apparatus according to claim 1,
wherein the image acquiring unit comprises an imaging section to capture the image, and acquires the image including the object image captured by the imaging section;
the distance acquiring unit comprises a distance measuring section that measures the distance to the object for the object image included in the image captured by the imaging section, and acquires the distance using the distance measuring section;
the painterly transformation processor transforms the object image included in the captured image into the painterly image;
the thickness information acquiring unit acquires the thickness information corresponding to the distance measured by the distance measuring section for the corresponding line having the style corresponding to the acquired distance; and
the data generating unit generates the data in which the line and the thickness information are associated with each other.

### Claim 7 (depends on 1)

The image processing apparatus according to claim 1, further comprising:
a first controller that performs control to apply a three-dimensional layer to a printing medium, the three-dimensional layer having a thickness corresponding to the acquired distance for the corresponding line having the style corresponding to the acquired distance; and
a second controller that performs control to apply the painterly image to the three-dimensional layer applied to the printing medium by the first controller.

### Claim 8 (depends on 7)

The image processing apparatus according to claim 7, wherein the first controller comprises a thickness controller that performs control so that the three-dimensional layer is applied to the printing medium thickly in an upper portion of the three-dimensional layer and more thinly as a position in the three-dimensional layer becomes lower.

### Claim 9

A printer comprising:
a data acquiring unit that acquires data in which a painterly image and thickness information are associated with each other;
a first controller that performs control to apply a three-dimensional layer to a printing medium based on the thickness information acquired by the data acquiring unit; and
a second controller that performs control to apply the painterly image acquired by the data acquiring unit, to the three-dimensional layer applied to the printing medium by the first controller;
wherein:
the painterly image includes an object image;
a contour of the object image included in the painterly image is transformed into a line having a style corresponding to a distance for the object image; and
the thickness information corresponding to the distance for the object image is added for the corresponding line having the style corresponding to the distance.

### Claim 10 (depends on 9)

The printer according to claim 9, wherein the first controller comprises a thickness controller that performs control so that the three-dimensional layer is applied to the printing medium thickly in an upper portion of the three-dimensional layer and more thinly as a position in the three-dimensional layer becomes lower.

### Claim 11

An image processing method using an image processing apparatus which comprises a CPU, the method comprising:
acquiring an image with the CPU;
acquiring, with the CPU, a distance to an object for an object image included in the acquired image;
extracting, with the CPU, a contour of the object image;
transforming, with the CPU, the object image included in the acquired image into a painterly image, wherein transforming the object image into the painterly image comprises transforming the extracted contour of the object image into a line having a style corresponding to the acquired distance;
acquiring, with the CPU, thickness information corresponding to the acquired distance for the corresponding line having the style corresponding to the acquired distance; and
generating, with the CPU, data in which the line and the thickness information are associated with each other.
