an image processing apparatus for performing image processing on the image captured by said image capturing apparatus, comprising:
a correction unit for correcting the second image when said backlight status detector detects the backlight status;
wherein said image capturing apparatus further comprises a extracting unit for extracting a second subject area which is an area indicating the subject and a second background area which is an area indicating a background of the subject;
wherein said extracting unit further extracts the first background area, which is an area corresponding to the second background area, from the first image, and
said correction unit generates a composite image based on the second subject area and the first background area when said backlight status detector detects the backlight status.
3. The image processing system as claimed in claim 1 or claim 2, wherein said image capturing apparatus further comprises a storing unit for associating the second image and detecting result of the backlight status detected by said backlight status detector and storing the second image and the detecting result.
4. The image processing system as claimed in claim 1 or in claim 2, wherein said image capturing apparatus further comprises an electric flash for flashing light in response to the second instruction signal.
5. The image processing system as claimed in claim 3, wherein
said image capturing apparatus further comprises an electric flash for flashing light in response to the second instruction signal,
said extracting unit further extracts a first subject area which is an area corresponding to the second subject area, and a first background area which is an area corresponding to the second background area from the first image, and
when a brightness of the first subject area is lower than that of the first background area by a first predetermined value, and a brightness of the second subject area is higher than that of the first subject area by a second predetermined value, said backlight status detector judges such the status as the backlight status.
6. The image processing system as claimed in claim 5, wherein said correction unit heightens the brightness of the second subject area when said backlight status detector detects the backlight status and the brightness of the second subject area is lower than a third predetermined value.
7. The image processing system as claimed in claim 6, wherein
said image capturing apparatus further includes an electric flash for flashing light in response to the second instruction signal, and
said correction unit lowers brightness of the second subject area when the brightness of the second subject area is higher than a fourth predetermined value.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
