## Abstract

In one embodiment, a method that includes comparing a subject color medical image to normal color medical image data; and identifying abnormal pixels from the subject color medical image. Another embodiment includes a computer readable medium comprising machine readable instructions for implementing one or more steps of that method. Another embodiment includes a device that has a field programmable gate array configured to perform one or more of the steps of that method. Another embodiment includes a device that has an application specific integrated circuit configured to perform one or more of the steps of that method.

## Claims

### Claim 1

A method comprising:
comparing a subject color medical image acquired using an endoscope to normal color medical image data;
identifying abnormal pixels from the subject color medical image; and
graphically displaying the subject color medical image and highlighting areas of the subject color medical image that have a saturation that is greater than normal.

### Claim 2

A method comprising:
graphically displaying a subject color medical image acquired using an endoscope;
comparing the subject color medical image to normal color medical image data to identify abnormal pixels from the subject color medical image; and
highlighting abnormal pixels on the displayed subject color medical image;
where the highlighting includes highlighting areas of the displayed subject color medical image that have a saturation that is greater than normal.

### Claim 3

A method comprising:
acquiring a subject color medical image using an endoscope;
displaying a region of interest from the subject color medical image;
comparing the region of interest to normal color medical image data to identify abnormal pixels from the region of interest; and
highlighting abnormal pixels on the displayed region of interest;
where the highlighting includes highlighting areas of the displayed region of interest that have a saturation that is greater than normal.

### Claim 4

A method comprising:
comparing a subject color medical image to normal color medical image data;
identifying abnormal pixels from the subject color medical image; and
displaying the subject color medical image and highlighting areas of the subject color medical image that have a saturation that is greater than normal;
where the comparing, the identifying, the displaying, and the highlighting are performed using a computer system programmed for the comparing, the identifying, the displaying, and the highlighting.

### Claim 5

A method comprising:
displaying a subject color medical image;
comparing the subject color medical image to normal color medical image data to identify abnormal pixels from the subject color medical image; and
highlighting abnormal pixels on the displayed subject color medical image;
where the highlighting includes highlighting areas of the displayed subject color medical image that have a saturation that is greater than normal; and
where the displaying, the comparing, and the highlighting are performed using a computer system programmed for the displaying, the comparing, and the highlighting.
