    • A bit-resolution-extension method is provided. The resolution extension method includes normalizing n-m upper bit values of adjacent pixels based on an upper n-m bit value of each pixel of a sample image, analyzing a statistical distribution of a lower m bit value of the reference pixel by patterns of a set consisting of the normalized adjacent pixels, generating a memory address from normalized adjacent pixel values of the sample image, saving a representative value of the lower m bits by patterns to the memory address as a result of the analysis, normalizing adjacent pixel values based on each pixel value of an input image, generating the memory address from the normalized adjacent pixel value of the input image, reading a representative value of the lower m bits saved in the memory address, and adding the read lower m bits to the input image pixel values as lower bits.
    • 提供了位分辨率扩展方法。 分辨率扩展方法包括基于样本图像的每个像素的上位数值来对相邻像素的nm高位值进行归一化,通过以下方式分析参考像素的较低m位值的统计分布: 归一化的相邻像素,从采样图像的标准化相邻像素值生成存储器地址,作为分析的结果,将存储器地址中的低m位的代表值作为模式保存到存储器地址,基于每个像素值的 输入图像,从输入图像的标准化相邻像素值生成存储器地址,读取保存在存储器地址中的较低m位的代表值,并将读出的较低m位作为较低位加到输入图像像素值 。

    • A bit resolution-extension method is provided. The bit resolution-extension method includes acquiring the shortest distance from a central pixel to a positive contour and the shortest distance from the central pixel to a negative contour in a filtering region which scans the positive contour comprising large pixels of a fixed value and the negative contour comprising small pixels of a fixed value, based on a value of the central pixel, generating an extension bit of the central pixel by interpolating the shortest distance from the central pixel to the positive contour and the shortest distance from the central pixel to the negative contour, and adding the extension bit as a lower bit of the central pixel.
    • 提供了一种分辨率 - 扩展方法。 比特分辨率 - 扩展方法包括获取从中心像素到正轮廓的最短距离以及在扫描包括固定值的大像素的正轮廓的过滤区域中的从中心像素到负轮廓的最短距离,并且否定 基于中心像素的值,包括固定值的小像素的轮廓,通过内插从中心像素到正轮廓的最短距离和从中心像素到负的最短距离来生成中心像素的扩展位 轮廓,并将扩展位添加为中心像素的较低位。
