To provide adaptive image processing for a portrait, face information about the face of a person contained in an image is acquired, and it is determined on the basis of the face information whether a significant personal face is contained in the image. If there is face information representing the presence of a significant personal face, adaptive processing adjustment information which adjusts the contents of high quality processing for a portrait, which should be executed for the process target image, is generated from the face information about the face of the person contained in the image. The high quality processing adjusted on the basis of the adaptive processing adjustment information is executed for the image.

What is claimed is: 1. An image processing method performed by an image processing apparatus comprising the steps of: inputting into the image processing apparatus image data representing an input image which contains a plurality of face images; detecting with a detector of the image processing apparatus plural face-image areas corresponding to the plurality of face images; calculating with a calculator of the image processing apparatus a size of each of the plurality of face images included in the detected plural face-image areas; determining with a determiner of the image processing apparatus a maximum size among the calculated sizes of the plurality of face images; setting with a setting section of the image processing apparatus a first correcting condition based on the determined maximum size and an input-image size; and correcting with a corrector of the image processing apparatus the image data of the entire input image using the first correcting condition, regardless of the calculated size of each of the plurality of face images, by using a mathematical formula containing a coefficient, wherein the coefficient depends on the value of the set first correcting condition, and wherein the same mathematical formula is used to calculate the corrected image data for different values of the first correcting condition, but with the value of the coefficient changed, in accordance with the value of the first correcting condition. 2. The method according to claim 1, wherein the correcting step performs a weighting processing on the image data corrected using one of three different values for the coefficient, based on the first correcting condition. 3. The method according to claim 1, wherein the first correcting condition is set in accordance with a ratio of the maximum size to the input-image size. 4. The method according to claim 1, wherein the correction performed in the correcting step includes at least one of skin color correction processing for correcting a color of skin of a person, noise removal processing, and spatial filter processing. 5. The method according to claim 1, wherein the setting step sets the first correcting condition based on the maximum size, the input-image size and a position of the face-image area corresponding to the maximum size. 6. The method according to claim 1, wherein the setting step sets the first correcting condition in common with the plural face-image areas and the another image area. 7. An image processing apparatus, comprising: an input section, arranged to input image data representing an input image which contains a plurality of face images; a detector, arranged to detect plural face-image areas corresponding to the plurality of face images; a calculator, arranged to calculate a size of each of the plurality of face images included in the detected plural face-image areas; a determiner, arranged to determine a maximum size among the calculated sizes of the plurality of face images; a setting section, arranged to set a correcting condition based on the determined maximum size and an input-image size; and a corrector, arranged to correct the image data of the entire input image using the correcting condition, regardless of the calculated size of each of the plurality of face images, by using a mathematical formula containing a coefficient, wherein the coefficient depends on the value of the set correcting condition, and wherein the same mathematical formula is used to calculate the corrected image data for different values of the correcting condition, but with the value of the coefficient changed, in accordance with the value of the first correcting condition. 8. A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to perform an image processing method, the method comprising the steps of: inputting image data representing an input image which contains a plurality of face images; detecting plural face-image areas corresponding to the plurality of face images; calculating a size of each of the plurality of face images included in the detected plural face-image areas; determining a maximum size among the calculated sizes of the plurality of face images; setting a correction condition based on the maximum size and an input-image size; and correcting the image data of the entire input image using the correcting condition, regardless of the calculated size of each of the plurality of face images, by using a mathematical formula containing a coefficient, wherein the coefficient depends on the value of the set correcting condition, and wherein the same mathematical formula is used to calculate the corrected image data for different values of the correcting condition, but with the value of the coefficient changed, in accordance with the value of the first correcting condition input image data using the correcting condition.
