摘要： In contrast enhancement during image processing, a histogram equalization process or apparatus divides an equalization image screen into overlapping windows and performs histogram equalization on each window. Using windows improves contrast of pixel values that are rare throughout the entire image and reduces or prevents loss of information represented by the rare pixel values. Overlapping the windows reduces discontinuities at the boundaries of the windows. The size and overlap of the windows can be adjusted according to the time available for equalization and can be optimized according to the desired image quality improvement. The histogram equalization can be selectively performed on an entire image screen or any part thereof to reduce image degradation in the entire or part of an image. As a further aspect of the invention, to reduce the number of operations required for equalization, a histogram for a current window is obtained starting from the histogram for a previous window. To further improve image quality, a histogram equalization apparatus uses low-pass- or band-pass-filtered pixel data as a lookup table address to output a histogram-equalized value. This helps remove amplified thermal or quantization noise.

摘要： 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.
