## Abstract

A system for editing preview images. The system includes at least one source end, a control terminal and at least one display end. The control terminal is coupled between the source end and the display end. The source end provides at least one image. The control terminal provides a user interface. The control terminal includes an image capture module, a previewing module and a media parameter module.

## Claims

### Claim 1

A system for editing preview images, comprising:
at least one source end, providing at least one image;
a control end, coupled to the at least one source end, wherein the control end includes:
a capture module, for capturing at least one specified area of the image;
a preview module, for displaying at least one preview window on a display screen of the control end to display the at least one specified area of the image;
a media display parameter setting module, for setting parameters related to the at least one specified area of the image; and
at least one display end, coupled to the control end, for receiving the at least one specified area of the image which was displayed in the preview window;
wherein the media display parameter setting module adjusts a size of the specified area according to the setting parameters so as to match a screen size at the display end.

### Claim 2 (depends on 1)

The system of claim 1, wherein the size of the specified area has a width and a height and contains image content including image pixels.

### Claim 3 (depends on 1)

The system of claim 1, wherein the media display parameter setting module includes a correction unit for correcting an aspect ratio of the specified area according to either a first mode or a second mode, wherein in the first mode, the correction unit obtains Extended Display Identifier Data (EDID) of the at least one display end and automatically adjusts the aspect ratio based on the EDID, and wherein in the second mode, the correction unit receives a command containing parameters, and automatically adjusts the aspect ratio based on the received parameters.

### Claim 4 (depends on 1)

The system of claim 1, wherein the media display parameter setting module includes a cutting unit for cutting the specified area into a plurality of sub-areas.

### Claim 5 (depends on 4)

The system of claim 4, wherein the media display parameter setting module includes a zoom unit for enlarging or reducing sizes of the plurality of sub-areas.

### Claim 6 (depends on 5)

The system of claim 5, wherein the media display parameter setting module includes a combining unit for combining the plurality of sub-areas, after they have been processed by the zoom unit, into one image.

### Claim 7 (depends on 4)

The system of claim 4, wherein the display end includes a plurality of display devices, and wherein the media display parameter setting module includes a selecting unit for pairing each of the plurality of sub-areas with one of the display devices of the display end.

### Claim 8 (depends on 1)

The system of claim 1,
wherein the source end includes a plurality of media players for outputting a plurality of images;
wherein the control end is coupled to a computer, the control end includes an image switch, image distribution device or video matrix; and
wherein the display end includes a plurality of display devices installed in a predetermined configuration forming a TV wall.

### Claim 9

A device for editing preview images, coupled between at least one external source device and at least one external display device, the device comprising:
a processing unit;
a receiver coupled to the processing unit, for receiving at least one image from the at least one external source device;
a memory unit, coupled to the processing unit, for storing a preview image editing module, which comprises:
a preview unit for providing at least one preview window for displaying the at least one image;
a capture unit for providing a capture tool for capturing at least one specified area of the at least one image; and
a media display parameter setting unit for setting parameters related to the at least one specified area of the at least one image; and
a transmitter, coupled to the processing unit, for transmitting the at least one specified area of the at least one image to the at least one external display device,
wherein the media display parameter setting unit adjusts a size of the specified area according to the setting parameters so as to match a screen size of the at least one external display device.

### Claim 10 (depends on 9)

The device of claim 9, further comprising:
an input unit, coupled to the processing unit, for inputting commands and parameters; and
a monitor for displaying and interacting with a user interface and the at least one preview window; and
wherein the size of the specified area has a width and a height and contains image content including image pixels.

### Claim 11 (depends on 10)

The device of claim 10, wherein the media display parameter setting unit includes a correction unit for correcting an aspect ratio of the specified area according to either a first mode or a second mode, wherein in the first mode, the correction unit obtains Extended Display Identifier Data (EDID) of the at least one external display device and automatically adjusts the aspect ratio based on the EDID, and wherein in the second mode, the correction unit receives a command containing parameters via the user interface, and automatically adjusts the aspect ratio based on the received parameters.

### Claim 12 (depends on 9)

The device of claim 9, wherein the media display parameter setting unit includes a cutting unit for cutting the specified area into a plurality of sub-areas.

### Claim 13 (depends on 12)

The device of claim 12, wherein the media display parameter setting unit includes a zoom unit for enlarging or reducing sizes of the plurality of sub-areas.

### Claim 14 (depends on 13)

The device of claim 13, wherein the media display parameter setting unit includes a combining unit for combining the plurality of sub-areas, after they have been processed by the zoom unit, into one image.

### Claim 15 (depends on 12)

The system of claim 12, wherein the media display parameter setting unit includes a selecting unit for pairing each of the plurality of sub-areas with one of the external display devices.
