Abstract
An image processing apparatus which can perform a variety of graphic processing using a video signal obtained by an image pickup apparatus. A system comprising a DDA set-up circuit for generating first image data and first z-data, a triangle circuit, a texture engine circuit, and a memory I/F circuit for writing the first image data and the first z-data respectively in a display buffer memory and a x-buffer memory and for writing the second image data and the second z-data respectively to the display buffer memory and the z-buffer memory when second image data corresponding to image pickup results of an image pickup apparatus and second x-data corresponding to the second image data are input from the video signal generator.
Claims19
An image processing apparatus comprising:
- a first memory for storing image data for output to a display;
- a second memory for storing depth data of said image data;
- an image processing circuit for performing three-dimensional graphic processing of predetermined data to generate a three-dimensional image data including first image data and first depth data corresponding to the first image data;
- and
- a write circuit for writing said first image data and said first depth data respectively in said first memory and said second memory as said image data and said depth data and, when second image data corresponding to image pickup-data and second depth data corresponding to said second image data are input, writing said second image data and said second depth data respectively to said first memory and said second memory as said image data and said depth data.
An image processing method comprising the steps of:
- performing three-dimensional graphic processing to generate first image data and first depth data corresponding to said first image data;
- writing said first image data and said first depth data in a first memory for storing-image data to be output to a display and a second memory for storing depth data of image data stored in said first memory respectively;
- generating second image data corresponding to image pickup data and second depth data corresponding to said second image data;
- and
- writing said second image data and said second depth data respectively to said first memory and said second memory.
