An image processing apparatus and a program for causing an information processing system to execute steps involves automatically specifying an area to be subjected to the image correction process such as an area of a human image in an image containing the human image, and an image correction process such as the gradation process is executed only for the specified area.

Image processing device

An object of the invention is to provide an apparatus which performs correction only to a high-brightness portion generated in a particular region, in which a decrease in brightness is necessary, and glaze is removed or reduced. A correction process in which the brightness or the lightness is decreased is simply performed to a pixel in which the brightness or the lightness is high, but a predetermined region (for example, face, eyes, and mouth) of a subject is detected and a degree of correction of each pixel is determined based on the detection result (a position and a color of the predetermined region). Therefore, the region in which the decrease in brightness is not necessary is maintained at high brightness, and the image correction is performed only to the region in which the decrease in brightness is necessary (for example, the region in which the glaze of a skin is generated).

Image correction apparatus

To surely and automatically determine intermixture of images of another person without resorting to human labor and to beforehand prevent dishonest registration due to substitution, there are provided a face position detection unit for detecting a face position from images acquired by using a camera to consecutively photograph a face, a face position variation calculation unit for calculating a variation between a face position detected at this time and a face position detected at the last time, a determination unit for comparing the calculated variation of the position with a predetermined threshold to determine the image at this time as a registrable one when the variation does not amount to the threshold and to determine the image at this time as an unregistrable one when the variation exceeds the threshold, and a storage unit for registering and storing those images, which are determined to be registrable.

Dishonest registration preventive apparatus in personal authentication system

An image creating apparatus for creating plural kinds of images which are different in each image class about brushwork and expression based on data of a single image, which includes a face component library ( ) and a rule library ( ). The face component library ( ) is composed of image libraries ( to ) of the respective face components such as eyes, noses, mouths and so forth each of which stores a plurality of image groups of the respective face components having different image elements in each of image classes &ldquo;i&equals;1 to n&rdquo;. An eye image library stores an image group composed by a plurality of eye images having different image elements about slant and roundness for each image class. The image elements are an item for measurement about character quantities extracted from the entered image data. In the same manner, the rule library ( ) is composed of a select rule library ( ), a deform rule library ( ) and an arrange rule library ( ) which store rule groups consisting of a plurality of rules for each face component about each image class (i&equals;1 to n).
