    Abstract: 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.

    Abstract: A field emission display apparatus including a field emission display panel and a driving device for the field emission display panel. The driving device includes a power supply unit, the power supply unit including an abnormal current detection unit and a discharge circuit. The abnormal current detection unit generates an arc-current detection signal when the value of a current flowing between a negative anode voltage terminal of the field emission display panel and a common ground line is larger than an upper limit. The discharge circuit generates a short circuit between an anode plate of the field emission display panel and the negative anode voltage terminal when the arc-current detection signal is generated from the abnormal current detection unit.
