    • A display device includes a wavelet transform unit for transforming an original image into wavelet coefficients using a Harr wavelet transform formula, a level obtaining unit for obtaining a mipmap level of a mipmap image. The display device also includes an inverse wavelet transform unit for receiving and subjecting at least a portion of the wavelet coefficients obtained by the transformation by the wavelet transform unit, to an inverse transform using an inverse Harr wavelet transform formula until an order having a value equal to the mipmap level is obtained, and outputting an image represented by at least a portion of a low-frequency component of wavelet coefficients having the order having the value equal to the mipmap level. Additionally, the display device includes a polygon drawing unit for drawing the image output by the inverse wavelet transform unit, as a mipmap image, on the polygon image.

    • In an image generation device that includes a memory in which a burst length, which is the smallest unit of read/write processing, is large, an image generation device in which processing efficiency at the time of a memory access does not decrease, even in the case of accessing a rendering buffer for rendering a polygon. Image data is stored in the rendering buffer in block units made up of plural pixels. At this time, image data of pixels corresponding to the polygon is stored in a serial region of the rendering buffer. A valid pixel flag indicating that a valid pixel is present within the block is stored in a rendering information buffer. The rendering buffer is accessed as little as possible based on placement of the valid pixel flags within the block.
    • 在包括作为读/写处理的最小单位的突发长度大的存储器的图像生成装置中,即使在存储器访问时的处理效率也不降低的图像生成装置 访问用于渲染多边形的渲染缓冲区的情况。 图像数据以由多个像素组成的块单元存储在渲染缓冲器中。 此时,与多边形对应的像素的图像数据被存储在呈现缓冲器的串行区域中。 指示在块内存在有效像素的有效像素标志被存储在呈现信息缓冲器中。 基于块内有效像素标记的放置,尽可能少地访问渲染缓冲区。
