## Abstract

A system for generating image content, the system comprising an image region identification unit operable to identify one or more regions of an image to be displayed as low-detail regions, an image processing unit operable to perform processing to reduce colour differences for each of one or more areas within one or more of the identified regions, and an image output unit operable to output one or more processed images.

## Claims

### Claim 1

A system for generating image content, the system comprising:
an image region identification unit operable to identify one or more regions of an image to be displayed as low-detail regions;
an image processing unit operable to perform processing to reduce colour differences for each of one or more areas within one or more of the identified regions; and
an image output unit operable to output one or more processed images, where the one or more processed images include each of the one or more areas having the reduced colour differences.

### Claim 2 (depends on 1)

The system of claim 1, wherein the image region identification unit is operable to identify the one or more regions of the image to be displayed in dependence upon the location of one or more objects within the image to be displayed.

### Claim 3 (depends on 1)

The system of claim 1, wherein the image region identification unit is operable to identify the one or more regions of the image to be displayed in dependence upon the location of one or more objects within the scene represented by the image to be displayed.

### Claim 4 (depends on 1)

The system of claim 1, wherein the image region identification unit is operable to identify the one or more regions of the image to be displayed in dependence upon their location relative to a predetermined position within the image to be displayed.

### Claim 5 (depends on 4)

The system of claim 4, wherein the predetermined position is the centre of the image or a point of user interest or focus.

### Claim 6 (depends on 1)

The system of claim 1, wherein the image region identification region is operable to identify one or more regions of the image in dependence upon one or more preceding or following images to be displayed.

### Claim 7 (depends on 1)

The system of claim 1, wherein the image to be displayed refers to an image to be rendered, or a rendered image.

### Claim 8 (depends on 1)

The system of claim 1, wherein the image processing unit is operable to identify a representative colour for each of the one or more areas, and to modify the colours of one or more pixels within the area so as to be closer to the representative colour.

### Claim 9 (depends on 8)

The system of claim 8, wherein the representative colour is the average colour value of the area.

### Claim 10 (depends on 8)

The system of claim 8, wherein the colours of one or more pixels are modified such that the colour values have an equal to or less than threshold deviation from the representative colour.

### Claim 11 (depends on 10)

The system of claim 10, comprising an image encoding unit operable to encode the processed image data.

### Claim 12 (depends on 11)

The system of claim 11, wherein the image encoding unit is operable to utilise a delta colour compression algorithm.

### Claim 13

A method for generating image content, the method comprising:
identifying one or more regions of an image to be displayed as low-detail regions;
performing processing to reduce colour differences for each of one or more areas within one or more of the identified regions; and
outputting one or more processed images, where the one or more processed images include each of the one or more areas having the reduced colour differences.

### Claim 14

A non-transitory machine-readable storage medium which stores computer software which, when executed by a computer, causes the computer to perform a method for generating image content, the method comprising:
identifying one or more regions of an image to be displayed as low-detail regions;
performing processing to reduce colour differences for each of one or more areas within one or more of the identified regions; and
outputting one or more processed images, where the one or more processed images include each of the one or more areas having the reduced colour differences.
