The invention discloses a method for eliminating dynamic streaking of liquid crystal display. The concrete steps include: (a). convert images of two following frames into black and white brightness signal images; (b). compare the pixels at the corresponding position in the black and white brightness signal images and retain the pixel with a smaller grayness value; (c). form a frame of black frame insertion images (Gn) with the group of pixels obtained after the comparison of each pair of pixels; (d). insert the black frame insertion images (Gn) into images of two following frames. The method of the invention is to compare continuous image signals of two frames, and form a frame of 'new grayness distribution signal' with the darker pixels of each pixel position as the black frame insertion image to reach the purpose of lowering MPRT and eliminating streaking of dynamic images. The invention can not only overcome the shortcoming of the low efficiency of the black frame insertion technique, but also overcome the inadequate elimination of dynamic blurs and the high decline of the contrast in gray frame insertion technique. In addition, the method of obtaining insertion frames is simple and accessible, thus greatly saving the production cost.

An image processing apparatus includes a still / motion determining unit and a motion blur adder. The still / motion determining unit makes a still / motion determination for each region of respective unit images constituting motion image data. The motion blur adder then adds motion blur to the motion image data on the basis of the still / motion determination and imaging information expressing parameters whereby the motion image data was generated as a result of imaging by an imaging apparatus.

The invention is applied in the technical field of LCD display, and provides a grey insertion method and a drive circuit for the LCD display, wherein the method comprises the following steps of: judging that the LCD display displays a dynamic frame or static frame; when the LCD display displays the dynamic frame, improving the extent of the grey insertion of the frame displayed by the LCD display, and synchronously prolonging a working cycle of a pulse width modulation signal, wherein the pulse width modulation signal is used for driving a backlight module of the LCD display; and when the LCDdisplay displays the static frame, reducing the extent of the grey insertion of the frame displayed by the LCD display, and synchronously shortening the working cycle of the pulse width modulation signal. Because a frame detector is used to judge that a second frame displayed by the LCD display is the dynamic frame or static frame, the increase or decrease of the extent of the grey insertion of the frame is determined, and the working cycle of the pulse width modulation signal is synchronously prolonged or shortened, the method and the drive circuit can be suitably used for adjusting the extent of the grey insertion of the frame, synchronously adjusting the brightness of the backlight, and improving the dynamic fuzzy problem of the dynamic frame.
