A flash memory device comprises alternately arranged odd and even memory cells. The odd and even memory cells are connected to corresponding odd and even bitlines, which are connected to corresponding odd and even page buffers. In a read operation of the flash memory device, data is sensed at two different times via the odd and even bitlines. In certain embodiments, data is read from the odd page buffers while data is being sensed via the even bit lines, or vice versa.

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.

摘要:
A driving apparatus, and a driving method for an electron emission display, includes a controller for comparing external video data input signals, switching a polarity control signal in a predetermined period on the basis of the comparison and controlling a video data output signal in accordance with the polarity control signal, and a data driver for modulating the video data signal output from the controller. The switching of the polarity control signal may be shifted temporally when the comparison indicates the video data input signals have the same gray level.
