    • Digital focusing method and apparatus in an image processing system, for digitally focusing an out-of-focus image, are provided. A defocused image is divided into sub-images of a predetermined size. An edge direction of each of the divided sub-images is estimated. Step responses with respect to the respective edge directions are calculated. A mean step response is obtained by averaging a predetermined number of the step responses. Point Spread Function (PSF) coefficients are obtained using the mean step response. An image blur transfer function is obtained using the PSF coefficients. An image restoration transfer function is obtained using the image blur transfer function. An original in-focused image is obtained by multiplying the image restoration transfer function by the defocused image in a frequency domain. Thus, an image can be restored in real time, and the size and weight of the image processing system can be reduced.
    • 提供了一种图像处理系统中的数字聚焦方法和装置,用于数字聚焦失焦图像。 散焦图像被划分成预定尺寸的子图像。 估计每个分割子图像的边缘方向。 计算相对于各个边缘方向的阶跃响应。 通过平均预定数量的步骤响应获得平均阶跃响应。 点扩展函数(PSF)系数是使用平均阶跃响应获得的。 使用PSF系数获得图像模糊传递函数。 利用图像模糊传递函数获得图像恢复传递函数。 通过将图像恢复传递函数乘以频域中的散焦图像来获得原始的聚焦图像。 因此,可以实时地恢复图像,并且可以减小图像处理系统的尺寸和重量。
