Apparatus and method for image compositing
TLDR
In this article, an image compositing apparatus capable of producing a natural composite image, with a simple structure and a less occupying space, is presented. But it is not suitable for the task of image generation.Abstract:
The present invention provides an image compositing apparatus capable of producing a natural composite image, with a simple structure and a less occupying space. The present invention also provides a method for compositing an image by providing shadow-free conditions in a limited space for chroma-keying so that a subject image and a desired background image are naturally integrated as one image.read more

Imaging apparatus and image processing method therefor
Keiichi Sakurai,Tetsuji Makino +1 more
TL;DR: In this paper, a digital camera (1) has a CPU (30) and an image processing apparaatus (25) which acquires a contour from an image acquired by shooting a whiteboard (2) as a shooting target by using a Roberts filter.
Patent
Projector with adjustably positioned image plate
TL;DR: In this article, a projector is often positioned so that its optical axis is at an imperfect orthogonal angle with respect to a projection screen, which causes a keystone distortion as well as imperfect focus in the projected image.

Method and system for generating images using Gsprites
TL;DR: In this paper, a method for generating a images includes rendering graphical models comprising a scene to separate image layers called "gsprites", and then compositing these image layers to generate an image.
Patent
Picture image forming apparatus
TL;DR: In this paper, a panoramic picture image is created by combining divided picture images using a picture image forming and processing unit, which corrects deviations of images of an object at overlap regions caused by a difference in fields of view of imaging means or movement of the object to be imaged.
