Abstract
During a period in which it is necessary to display two or more images in a superimposed manner, an image generation block of an information processing apparatus supplies the data of the image concerned to a superimposition processing block. A first image acquisition block and a second image acquisition block of the superimposition processing block acquire a first image and a second image, respectively, to be displayed in a superimposed manner. A luminance range adjustment block adjusts at least one luminance range as required with amount of adjustment corresponding to an alpha (α) value set to the second image. An output value computation block executes the computation of alpha blending by use of the image after adjustment so as to determine the pixel value of a display image, thereby outputting the determined pixel value to an image output block.
