Abstract

A facial image photographed by a digital camera is downloaded to a PC. When a facial image correction program starts, a correction window and a correction item selection window open on a monitor. When a user opens the facial image in the correction window, a pixel extraction circuit extracts pixels representing a skin area, an eye area, a teeth area, and a hair area from the facial image. Correction items to be performed are determined in the correction item selection window. A cursor position detection circuit detects the position of a cursor in the correction window. When the cursor is in one of the areas, a facial image correction circuit judges whether the correction item corresponding to the area is selected. If the corresponding correction item is selected, the facial image correction circuit subjects a pixel pointed by the cursor to predetermined correction processing.

Claims

1. A method for correcting a facial image displayed on a monitor, said method comprising the steps of:

(a) extracting pixels representing specific areas from said facial image;

(b) determining a correction item to be performed out of plural correction items, each of said correction items corresponding to each of said areas;

(c) detecting the position of a cursor in said facial image displayed on said monitor; and

(d) if a pointed pixel pointed by said cursor is in said area corresponding to said correction item to be executed, subjecting said pointed pixel to correction process that is set in accordance with said correction item.

2. A method as recited in claim 1, wherein one of said correction items is skin correction, wherein when said pointed pixel is in a skin area and the color of said pointed pixel is outside of the range of predetermined skin color, the color of said pointed pixel is corrected.

3. A method as recited in claim 2, wherein said predetermined skin color is selectable from plural colors.

4. A method as recited in claim 1, wherein one of said correction items is red-eye correction, wherein when said pointed pixel is in an eye area and the color of said pointed pixel is red, the color of said pointed pixel is corrected.

5. A method as recited in claim 4, wherein said pointed pixel is corrected to a selected eye color.

6. A method as recited in claim 1, wherein one of said correction items is teeth color correction, wherein when said pointed pixel is in a teeth area and said pointed pixel has color out of a range of predetermined white, the color of said pointed pixel is corrected.

7. A method as recited in claim 1, wherein one of said correction items is hair color correction, wherein when said pointed pixel is in a hair area and the color of said pointed pixel is white, the color of said pointed pixel is corrected.

8. A method as recited in claim 7, wherein said pointed pixel is corrected to the same color as another pixel in said hair area.

9. A method as recited in claim 1, wherein one of said correction items is hair color correction, and said pointed pixel is corrected to a selected hair color.

10. A program for correcting a facial image that is capable of causing a computer to perform:

extracting pixels representing specific areas from said facial image displayed on a monitor;

determining a correction item to be performed out of plural correction items, each of said correction items corresponding to each of said areas;

detecting the position of a cursor in said facial imag displayed on said monitor; and

if a pointed pixel pointed by said cursor is in said area corresponding to said correction item to be executed, subjecting said pointed pixel to correction process that is set in accordance with said correction item.

11. A recording medium readable by a computer on which said program according to claim 10 is stored.
