Abstract

In the processing of image data, image data are analyzed to determine a characteristic of the image, and the characteristic and a first correction parameter in correspondence to the characteristic are displayed in a screen of a display device. A second correction parameter may be set in the screen of the display device by a user. The image data is corrected with the first correction parameter, but when the user sets a second correction parameter, the image data are corrected with the second correction parameter. Alternatively, The image data are corrected automatically with the first correction parameter, and the characteristic of the image data is displayed in a screen after the image data have been corrected.

Claims

1. An image processor comprising:

a controller which analyzes image data to determine a scene thereof and a first correction parameter that corresponds to the scene;

a display device which displays a) the scene of the image data obtained by said controller, b) the first correction parameter obtained by said controller in a selected condition and c) a second correction parameter that corresponds to the determined scene of the image data but differs from the first correction parameter in a screen; and

an instruction device by which a user enters an instruction to select one of the first and second correction parameters in the screen of said display device;

wherein said controller corrects the image data with the selected correction parameter.

2. The image processor according to claim 1, wherein said instruction device sets the first correction parameter obtained by said controller as a default correction parameter.

3. The image processor according to claim 1, wherein said display device displays the first correction parameter that corresponds to the determined scene and alternative correction parameters that do not correspond to the determined scene of the image data.

4. The image processor according to claim 1, wherein said display device further displays an image which has been corrected by said controller with the first correction parameter.

11. The image processor of claim 1, wherein a scene determined by said controller is at least one of color fog, backlight, underexposure, overexposure, night scene and normal.

5. An image processing method comprising the steps of:

analyzing image data to automatically determine a scene of the image data;

displaying the scene of the image data, a first correction parameter that corresponds to the determined scene and a second correction parameter that differs from the first correction parameter;

selecting one of the first and second correction parameters by a user; and

correcting the image data with the first correction parameter or with the second correction parameter based upon the user selection.

12. The image processing method of claim 5, wherein a scene determined in said step of analyzing image data is at least one of color fog, backlight, underexposure, overexposure, night scene and normal.

6. A computer readable storage medium storing a program that executes the steps of:

analyzing image data to automatically determine a scene thereof;

displaying the scene of the image data, a first correction parameter that corresponds to the determined scene, and a second correction parameter that differs from the first correction parameter;

receiving an instruction from a user to select one of the first and second correction parameters; and

correcting the image data with the first correction parameter or with the second correction parameter when the user enters an instruction to select the correction parameter.

7. The computer readable storage medium according to claim 6, said program further executing the step of setting the first correction parameter as a default correction parameter.

8. The computer readable storage medium according to claim 6, wherein in said displaying step, the first correction parameter that corresponds to the scene and correction parameters that do not correspond to the scene are displayed in the screen.

9. The computer readable storage medium according to claim 6, wherein in said displaying step, an image which has been corrected during said correcting step is also displayed.

13. The computer readable storage medium according to claim 6, wherein a scene determined in said step of analyzing image data is at least one of color fog, backlight, underexposure, overexposure, night scene and normal.

10. An image processor comprising:

an analyzer which analyzes image data to determine a scene thereof;

a decider which decides a first image correction process based on the determined scene;

a display device which displays the scene to a user, the first correction process and a second correction process that differs from the first correction process; and

a setter which receives a user'"'"'s instruction to select the first image correction process or the second correction process and sets the selected image correction process to perform the correction of the image data.

14. The image processor according to claim 10, wherein a scene determined by said analyzer is at least one of color fog, backlight, underexposure, overexposure, night scene and normal.
