    摘要： An imaging system may include an image sensor and an image encoder that encodes images from the image sensor with fixed output sizes and frame rates. The image encoder may encode images from the image sensor into an image format such as a Joint Photographic Experts Group (JPEG) format. The image encoder may insert padding data between image blocks in the encoded data to compensate in real time for variations in the encoded size of an image. The amount of padding data inserted by the encoder may be calculated to ensure the encoded image has a file size close to, but not greater than, the required fixed output size. If needed, the encoder may add additional padding data after the image blocks are encoded in a blanking period before a subsequent image is encoded so that the final size of the encoded image is equal to the required output size.

    摘要： Multi-bit image edge enhancement method and apparatus wherein a group of gradient mask matrices are applied to a "current matrix", wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs. From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change. The current matrix and a predetermined number of previously evaluated and yet to be evaluated pixels are then compared to a set of reference bit patterns which depict possible segment changes to be corrected. If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition. In the case of an electrophotographic or a gray scale printing machine, the specific code will change either the location or the size of the TBAP; whereas in the case of a monochrome screen display, the specific code will change the intensity of the TBAP.

    摘要翻译： 多位图像边缘增强方法和装置，其中将一组梯度掩模矩阵应用于“当前矩阵”，其中TBAP（待调整像素）被相邻像素包围，以确定TBAP是否在 亮度发生变化。 从该矩阵运算得出关于边缘的存在或不存在以及亮度变化的方向的结论。 然后将当前矩阵和预定数量的先前评估且尚待评估的像素与一组参考位模式进行比较，该组参考位模式描绘了要校正的可能段变化。 如果结果表明TBAP位于边沿段的边缘，则将生成相应的代码来修改TBAP以提高段转换的平滑度。 在电子照相或灰度打印机的情况下，具体代码将改变TBAP的位置或大小; 而在单色屏幕显示的情况下，具体代码将改变TBAP的强度。
