Abstract: The image processing device includes an unit for generating plural processed images from a single input image, an identifying unit having identifying function and dictionary data for the identifying function and processing the processed image using a combination of an identifying function corresponding to a target object and the dictionary data for the identifying function to detect the target object in the input image and an unit for calculating positional coordinates of the target object in the input image using a result of detecting the target object.

Abstract: An image processing apparatus which processes an input image to detect a specified object of interest that is recorded in the input image is provided. The apparatus has a detection unit and a position determining unit. The detection unit has a plurality of identifying subunits each of which identifies an object from the input image under a different condition. The detection unit detects a region of the identified object. The position determining unit calculates the position coordinates of the object of interest in the input image from the region of the identified object. The detection unit performs the identification and the detection repeatedly and the detection unit performs the identification and the detection by using a detected region of an identified object in the previous identification. The detection unit detects the specified object of interest using the repeatedly detected regions.

Abstract: An information recording device and an information recording system which can effectively use empty space of a recording medium, which empty space is formed after writing of image data. Advertisement information or positional information representing a position of the advertisement information is selected based on personal information of an orderer, photographing information representing a situation at the time of photographing, or the image data itself. The selected information is written onto empty space of a removable medium after the image data has been written thereon.
