Abstract

An image recording medium includes an image recording area in which an image signal can be recorded. The image signal is subjected to multiple image correction processes in a process order. The image recording medium also includes an information recording area in which data is recorded. The data indicates the process order in which the image correction processes were performed. An image signal process order system performs the image correction processes in a process order. The image signal process order system records the process order in the recording medium. An image signal process order device perform restoration process order in a restoration order. The restoring order is the reverse of the process order.

Claims

1. An image signal process order device that processes a corrected image signal obtained by performing a plurality of image correction processes to an image signal in a process order, comprising:

a process order determining processor that determines the process order; and

an image signal restoring processor that performs a plurality of restoration processes to the corrected image signal to restore the image signal, the plurality of restoration processes being performed in a restoring order which is the reverse of the process order,

wherein the plurality of image correction processes include a gamma correction.

3. The image signal process order device of claim 1, wherein data indicating the process order is recorded in an information recording area of an image recording medium, and the image signal is recorded in an image recording area of the image recording medium.

4. The image signal process order device of claim 1, further comprising an image recording medium that includes an image recording area in which the image signal is recorded, and an information recording area in which data indicating the process order is recorded.

6. The image signal process order device of claim 1, further comprising a program to process the corrected image signal, the program comprising:

a processing order data reading section executable to read processing order data from a first area of a storage; and

an image data reading section executable to read image data from a second area of the storage.

7. The image signal process order device of claim 6, the program further comprising:

a compressed data determining section executable to determine whether the image data stored in the second area of the storage comprises compressed image data; and

an expansion section executable to expand the image data read from the second area of the storage when the compressed data determining section determines that the image data stored in the second area of the storage comprises compressed image data.

8. The image signal process order device of claim 6, the program further comprising:

an image data display section executable to display a first image based upon the image data read from the second area of the storage; and

a process order display section executable to display a second image based upon the processing order read from the first area of the storage.

9. The image signal process order device of claim 8, wherein the image data display section and the process order display section are configured to superimpose the first image with the second image.

10. The image signal process order device of claim 6, the program further comprising:

a restoration process determining section executable to determine whether at least one of the plurality of restoration processes is to be performed.

11. The image signal process order device of claim 10, the program further comprising:

a command input receiving section executable to receive an input command;

a process stage determining section executable to determine a processing stage in the restoring order in which the at least one of the plurality of restoration processes is to be performed, wherein the processing stage is determined based upon the input command.

12. The image signal process order device of claim 11, the program further comprising:

a restoration processing section executable to carry out at least one of the plurality of restoration processes on the corrected image signal based on the processing stage and the restoring order.

2. An image signal process order system, comprising:

an image signal recording processor that records the corrected image signal in a recording medium;

a process order recording processor that records the process order in the recording medium;

a process order reading processor that reads the process order from the recording medium; and

an image signal restoring processor that performs restoration processes to the corrected image signal to restore the image signal, the restoration processes being performed in a restoring order, which is a reverse of the process order.

5. The image signal process order system of claim 2, wherein data indicating the process order is recorded in an information recording area of the recording medium, and the image signal is recorded in an image recording area of the recording medium.

13. An image signal process order device that processes a corrected image signal obtained by performing a plurality of image correction processes to an image signal in a process order, comprising:

a process order determining processor configured to determine the process order;

an image correcting processor configured to perform the plurality of image correction processes to the image signal in the process order to generate the corrected image signal, the plurality of image correction processes including a gamma correction;

an image signal recording processor configured to record the corrected image signal in a first storage area of a recording medium;
