摘要： A method is provided of processing image data for display by a display panel of a display device. The method comprises receiving main image pixel data representing a main image and side image pixel data representing a side image, and performing a mapping of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. A compression of the main image pixel data is performed in advance of or at least partly incorporated into the mapping, the compression being performed at least partly in dependence upon the main image pixel data and at least partly in dependence upon how the off-axis luminance varies with pixel data input to the mapping.

摘要： A method of processing image data for an image display panel comprises, in a first mode: determining signal voltages to be applied to pixels of the image display panel from received image data constituting an image for display on the image display panel and from a secondary data value for the pixel thereby to generate luminance variations perceivable at a first viewing position (5) but substantially not perceivable at a second viewing position (3). The signal voltages to be applied to pixels in a group of pixels are determined such that the overall luminance of the pixels in the group is dependent on (for example, proportional to) the overall luminance specified for the pixels in the group by the image data. The number of pixels in a group is locally variable and is selected according to the image data and/or the secondary data values for pixels in a region of the image where the group is to be defined. The invention makes it possible to specify luminance redistribution over an increased pixel group size in local regions in which the main image content is relatively uniform, with no high spatial resolution image features, while specifying luminance redistribution over a reduced pixel group size for main image regions with sharp edges and other high resolution features.

摘要： A method of processing image data for display on a display device having a multi-primary image display panel (2) comprises receiving image data constituting an image for display on the image display panel. In a first mode, signal voltages to be applied to sub-pixels of the image display panel are determined from the received image data and from a secondary data value for the pixel thereby to generate luminance variations perceivable at a first viewing position (5) but substantially not perceivable at a second viewing position (3). This provides a private display mode, since the luminance variations perceivable at the first viewing position (5) obscure the image from an observer at the first viewing position, while an observer at the second viewing position (3) is able to perceive the image since the luminance variations are not perceivable (or are substantially not perceivable) at the second viewing position In a second mode, signal voltages to be applied to sub-pixels of the image display panel may be determined just from the received image data thereby to generate an image perceivable at the first viewing position (5) and at the second viewing position (3). This provides a public or wide-view display mode.

摘要： A method of operating a display device comprising a display panel comprises receiving main and side image pixel data respectively representing a main image (S1) and a side image (S2). For each of a plurality of pixel groups (S3), where each pixel group comprises at least one pixel of the main image pixel data and at least one spatially corresponding pixel of the side image pixel data, a predetermined mapping is performed (S4) using the pixel data of the pixel group as input. The mapping holds output pixel data for the input pixel data which is known to produce an average on-axis luminance with substantially no dependence on the side image pixel data of the group and an average off-axis luminance with substantially no dependence on the main image pixel data of the group. The signals used to drive the display panel are determined from the output pixel data (S5).

摘要： A display device is provided that comprises a liquid crystal display panel (2) for displaying an image by spatial light modulation. The image is represented by a plurality of image elements each having an image data value (7). The display device further comprises a display controller (1) arranged to determine a signal voltage to be applied to the panel (2) for each image element in dependence upon its image data value (7) and a secondary data value (8) for the element, there being a predetermined mapping between the data values and the signal voltage. The secondary data values (8) are arranged to vary across the image so as to introduce variations in luminance as a result of the mapping. The mapping and secondary data values (8) are mutually arranged to take account of the signal voltage to on-axis luminance response of the panel (2) so that the luminance variations introduced on-axis tend to balance locally through spatial averaging to, and hence would not be perceivable by, an on-axis viewer (3). The panel (2) furthermore has a non-linear off-axis luminance to on-axis luminance relationship, so that at least some of the luminance variations introduced off-axis do not balance locally through spatial averaging to, and hence would be perceivable by, an off-axis viewer (4).

摘要： A video image is processed (501, 502, 509. 51) to determine an edge strength in a region associated with each image pixel to be processed. For large edge strengths, the pixel is filtered by an edge-preserving filter, such as an epsilon filter (504). For very large edge strengths, no edge-preserving filtering is applied. For small edge strengths, the edge-preserving filtering is replaced by a smoothing filter (505, 506).

摘要： A display device includes control electronics and a pixellated liquid crystal (LC) panel. The control electronics receives inputs of main image data for a main image and side image data for a side image. The control electronics outputs combined image data combining the main and side images such that an on-axis viewer perceives from the combined image the main image, and an off-axis viewer perceives from the combined image the side image. The output image data comprises data values chosen from a set of available output data values for the pixels selected from multiple sets of available data values depending on at least on the side image data. For a pixel currently being processed, the output data value is chosen from the selected set of available output data values for which a resulting luminance value is closest to a target luminance value for the current pixel.
