1. A non-transitory computer readable medium of a camera device, the computer readable medium storing a program for causing a processor to execute an image processing method, wherein the camera device generates a moving image of a subject by continuously taking photographs of the subject, the camera device including: a display for displaying information including the moving image, a user interface that initiates a photographing operation to generate a photograph of the subject, the photograph comprising image data; and memory for storing information including the image data, the program comprising instructions for processing successive frames of the moving image until terminated responsive to a release input from a user, the processing comprising: determining whether a human face is included in a frame; detecting a facial position in the frame if the determining step determines that a face is included in the frame; and storing the detected facial position in the memory, wherein the determining of whether a human face is included in the frame comprises: determining whether a human face is included in a first frame of the successive frames; if a human face is not determined to be in the first frame, repeating the determining on a next frame of the successive frames; and if a human face is determined to be in the first frame, determining whether a human face is included in a next frame of the successive frames, and wherein the determining of whether a human face is included in the next frame of the successive frames comprises: determining a variation between the first frame and the next frame; if the variation exceeds a threshold, determining whether a human face is included in the next frame of the successive frames by processing each pixel of the next frame; and if the variation does not exceed the threshold, determining whether a human face is included in the next frame by processing only pixels in the next frame located in a region corresponding to the region of the first frame in which the human face was detected.
