A picture processor including a picture-deformation-information input section for inputting the information for the degree of enlargement/contraction of each portion of a picture; a decoding section for inputting encoded picture data of the picture, inputting the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, decoding the picture data every portion of the picture in accordance with the information for the degree of enlargement/contraction, and moreover decoding the whole picture data independently of the information for the degree of enlargement/contraction; a reference picture generation section for generating a reference picture enlarged or contracted for each portion of the picture by using a picture in which the whole picture data is decoded supplied from the decoding section, the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, and the movement vector of the picture data; and an addition section for adding a picture decoded for each portion of the picture supplied from the decoding section and a reference picture supplied from the reference-picture generation section.

An apparatus comprises an object generation unit for generating an object based on three-dimensional object data externally input, an object position determination unit that moves the generated object according to a user input, and thereby determines an object position, a view point position determination unit that moves a view point according to the user input and thereby determines a view point position, a distance calculation unit for calculating a distance from the object position and the view point position, a frame rate determination unit for determining a frame rate corresponding to the calculated distance on the basis of a set table or formula, and a frame rate control unit and a moving image generation unit for reproducing the moving image with the frame rate of moving image data externally input reduced.

A 3-dimensional animation generating apparatus includes an image data storing section, a view point information input section, an image supervising section, an image data selecting section, a view point coordinate transforming section, an output image drawing section, a motion addressing section, a shadow area detecting section, and a shadow area supervising section. The image data storing section stores part image data and background image data in association with 3-dimensional coordinates of vertexes included in the image. The image data selecting section searches the image data by a unit of part. The apparatus further comprises a mechanism which, when information related to an observing view point is provided, determines which part image data exists in the visible area, transforms the visible part image data from the observing view point by view point coordinate transformation, and draws the resultant image data in a common drawing area. In addition, the apparatus further searches and supervises the part which can provide a shadow as a shadow area and the position of the light source related with the specific shadow area. When a new view point is selected, the shadow area transformed by view point coordinate transformation is drawn. Thus, the number of data and number of calculations for generating a scene with respect to a selected observing view point are effectively reduced.

Color compensation is performed in color images for use in an image processing field which is employed for three-dimensional computer graphics and the like by making a luminance value of texture data coincide with an intensity derived by an intensity calculation. Also, lightness compensation is performed for a color image according to a display scene. From measurements of color changes of plural colors in a uniform color space, a color change of arbitrary texture data under a chromatic color light source is represented and compensated. The generated image is very natural because compensation is achieved between a lightness of a texture itself representing a pattern on the surface of an object and an intensity of the surface of the object derived by an intensity calculation when an image is generated.

An image displaying system interactively changes the positions of the view vector and the viewpoint in the 3-dimensional space of a camera model which displays an object geometric model, constructed within a computer, on the screen in the computer assisted design (CAD) and science art simulation field. The user inputs the object point and the target point on the display screen showing the viewpoint and the view vector direction so as to effect the screen display of the scene with the positions of the view vector and the viewpoint in the 3-dimensional space of the camera model for displaying on the screen the object geometric model constructed within the computer. The scene with the viewpoint and the view vector direction being interactively changed is displayed on the screen.
