Downloading image graphics with accelerated text character and line art creation |
摘要 |
An image is transferred from a sender to a receiver. The image is progressively re-created at a display of the receiver. First, a low-resolution full-color representation of the image is transferred. Then, a full-resolution limited-color representation of the image is sent. The pixel values of the full-resolution representation typically represent alpha-numerical characters or edges of features. The representations are combined to create a version of the image by modifying the pixels of first representation under control of the limited-color content of the spatially corresponding pixel of the second representation. The legibility of the combined image is achieved considerably faster than with conventional techniques.
