Abstract
The number of available sub-fields for stereoscopic displaying on plasma display panels is not high enough to insure a good grey-scale portrayal as well as a good false contour behaviour. Thus, the number of sub-fields is artificially increased by commonly addressing the sub-fields of two or more pixel lines so that the addressing time of the panel may be decreased for each sub-field.
Claims10
Method for processing video pictures for stereoscopic display on a display device (8) having a plurality of luminous elements, one or more of them corresponding to each of the pixels of a video picture, wherein each video picture includes a left and a right picture and wherein the time duration of a video frame or video field is divided into a plurality of sub-fields during which the luminous elements can be activated for light emission in small pulses corresponding to a sub-field code word which is used for brightness control, wherein the video frame corresponding to the video picture includes a left and a right field for stereoscopic displaying, characterized in that the sub-fields of the left field are grouped into at least two left sub-field groups (L1, L2) and those of the right field into at least two right sub-field groups (R1, R2) and the left and right sub-field groups (L1, L, R1, R2) of the video frame are arranged in an interlaced manner in the frame period:
Device for processing video pictures for stereoscopic display on a display device (8) having a plurality of luminous elements, one or more of them corresponding to each of the pixels of a video picture, wherein a video picture includes a left and a right picture, including sub-field coding means (5) for translating the input video data words in sub-field code words according to a specific division of the time duration of a video frame or video field into a plurality of sub-fields during which the luminous elements can be activated for light emission in small pulses corresponding to a sub-field code word which is used for brightness control, wherein the video frame corresponding to the video picture includes a left and a right field for stereoscopic displaying, characterized in that sub-field arranging means are provided which group the sub-fields of the left field into at least two left sub-field groups (L1, L2) and those of the right field into at least two right sub-field groups (R1, R2) and which arrange the left and right sub-field groups (L1, L2, R1, R2) of the video frame in an interlaced manner.
