Abstract: According to one aspect of the invention, an image processing apparatus scales the image size and places one image onto another to display a compose image. The image processing apparatus includes an input image storage, an image attribute storage, an internal working memory, an output image storage, a processing unit block calculator, and an image processor. The processing unit block calculator dynamically determines a processing unit block according to the size of the internal working memory, scaling factors, a display image position, a display image size, and the amount of processed image data. The image processor inputs the image data of front and back images based on the processing unit block and performs composition processing in each processing unit block by using the internal working memory.

Abstract: To provide an image processor, an image processing method, and an image processing program, none of which require special hardware implementation and installation of a program requiring a large calculation amount. An embodiment of the present invention relates to an image processor for representing a shaded space defined by an object in a 3D space blocking light from a light source, which generates boundary data including positional information on the light source and positional information on the object to calculate the brightness of the shaded space based on the generated boundary data. With such a structure, the shaded space can be represented as boundary data in the same form as the object data, making it possible to reflect the brightness of the shaded space in a display image through the same processing as object rendering without any special hardware implantation, suppress a calculation amount, and improve an image quality.

Abstract: A two-dimensional rectangular code symbol scanning device inputs two-dimensional image data containing two-dimensional rectangular code symbol data and detects code data corresponding to the two-dimensional rectangular code symbol data. The device has a projective transformation calculator for correcting distortion of the two-dimensional rectangular code symbol data by performing projective transformation of the two-dimensional rectangular code symbol data.
