  • Patent number: 11830177
    Abstract: An image processing apparatus acquires a first image which captures a scene including an object from a first viewpoint position and a second image which captures a scene including the object from a second viewpoint position, and associates a coordinate position corresponding to a position of a feature of the object on the first image with a coordinate position corresponding to a position of a feature of the object on the second image. The image processing apparatus determines a partial region in the second image corresponding to a give region in the first image based on the association, generates a synthesized image by replacing an image of the given region using an image of the determined partial region, and superimposing variation data on the synthesized image.

  • Patent number: 5309254
    Abstract: When image data having a halftone is binary-coded, each of pixel data is first read out as gradation data having multiple values, a judgement is made whether or this pixel data corresponds to a value within a predetermined range, and if this pixel data is present within this range, a halftone processing operation is carried out by way of the error diffusion method. On the other hand, if another judgement is made that the pixel data is out of this predetermined range, this pixel is simply binary-coded. Thus, a portion where characters have been written is not processed by the halftone processing operation by way of the error diffusion method, whereby a clear image may be reproduced.
