摘要： An image generation apparatus is provided with an image acquisition unit for acquiring images of a three-dimensional object from a plurality of positions along a curve by computer graphics or a television camera. A memory unit stores images obtained by the image acquisition unit. An address generating unit calculates a first address showing the position of the image acquisition and a second address showing the position corresponding to the direction of the line of sight in the image according to the first address, for each line of sight from a specified viewpoint according to the positional information for the viewpoint and the curve at the time of image acquisition. An image generation processing unit combines the image information read from the memory unit by the first and second addresses generated by the address generating unit and generates the image of the three-dimensional object. Display equipment displays the image.

摘要： A processing of causing a face image of a person A as an object of encoding to be deformed in correspondence to expression and motion of a face image of a person B as a reference image. The expression change and the motion from the model wire-frame are treated as fitting information, and this fitting information is made WA1 with respect to a first image of an object for photographing, while is made Wb1 with respect to a second image of an object for photographing. For example, the fitting information from a model wire-frame W00 to an image A1 is Wa1, and the fitting information from the image A1 to the model wire-frame W00 is Wa1. Next, an image A2 into which the first image A1 is caused to be deformed by a texture Ta1 of the first image A1 and a wire-frame function Wb1 Wa1 is obtained through composition. Texture mapping of sticking the texture Ta1 in correspondence to each of small areas of this wire-frame is carried out, whereby the image A2 into which the image A1 is caused to be deformed similarly to an image B1 is obtained through composition.

摘要： An object, typically photoconductor drum is electrically charged by placing a contact charger member in abutment with the object to be charged and applying voltage between the contact charger member and the object. Charging is effected by properly controlling the capacitance of the contact charger member, the capacitance of the object, and the applied voltage. A sufficient charged potential is achieved through the application of a relatively low voltage, while preventing ozone generation.
