Abstract

An image display apparatus includes a display device configured to display an image, a signal converter configured to provide a transformation process using transformation parameter information for an input image signal, and to generate a driving signal used to drive the display device, and a memory configured to store the transformation parameter information, the transformation parameter information being editable in a parameter editing apparatus that can communicate with the image display apparatus, wherein the memory stores the transformation parameter information edited by the parameter editing apparatus, and editing information of edited transformation parameter information used to reproduce the edited transformation parameter information in the parameter editing apparatus.

Claims

1. An image display apparatus comprising:

a display device configured to display an image;

a signal converter configured to provide a transformation process using transformation parameter information for an input image signal, and to generate a driving signal used to drive the display device; and

a memory configured to store the transformation parameter information,

wherein the transformation parameter information is editable in a parameter editing apparatus that can communicate with the image display apparatus, and

wherein the memory stores the transformation parameter information edited by the parameter editing apparatus, and editing information of edited transformation parameter information used to reproduce the edited transformation parameter information in the parameter editing apparatus.

2. The image display apparatus according to claim 1, wherein the parameter editing apparatus reproduces the transformation parameter information in a spline form, and the editing information contains information of a node position of a curve in the spline form.

3. An image display system comprising:

an image display apparatus; and

a parameter editing apparatus configured to communicate with the image display apparatus,

wherein an image display apparatus includes;

a display device configured to display an image;

a signal converter configured to provide a transformation process using transformation parameter information for an input image signal, and to generate a driving signal used to drive the display device; and

a memory configured to store the transformation parameter information,

wherein the transformation parameter information is editable in a parameter editing apparatus that can communicate with the image display apparatus, and

wherein the memory stores the transformation parameter information edited by the parameter editing apparatus, and editing information of edited transformation parameter information used to reproduce the edited transformation parameter information in the parameter editing apparatus.
