  • Publication number: 20150301647
    Abstract: An input device includes a touch panel including a touch sensor that detects an operation by an operator, and a display. The input device executes information processing based on information input on the touch sensor. The touch sensor is capable of changing a detection output to the information processing means, in accordance with a position of an object at a distance from the touch sensor. The input device also determines whether an operation on the touch sensor is performed with an operator's right hand or left hand, based on a distribution of the detection output from the touch sensor.

  • Publication number: 20150042769
    Abstract: 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.

  • Patent number: 8836715
    Abstract: A method 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.

  • Publication number: 20140210878
    Abstract: 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).

  • Publication number: 20140139915
    Abstract: An image display apparatus having sub-pixels of four colors is provided in which the resolution when an image is two-dimensionally displayed is not affected, and deterioration in the color balance of a three-dimensionally displayed image is suppressed. In the image display apparatus, the arrangement of a sub-pixel for displaying red for a left eye and a sub-pixel for displaying green for a right eye has been replaced with the arrangement of a sub-pixel (Lg1) for displaying green for the left eye and a sub-pixel (Rr1) for displaying red for the right eye. The arrangement of a sub-pixel for displaying blue for the left eye and a sub-pixel for displaying yellow for the right eye has been replaced with the arrangement of a sub-pixel (Lx1) for displaying yellow for the left eye and a sub-pixel (Rb1) for displaying blue for the right eye. Replacement with the sub-pixel and the sub-pixel and replacement with the sub-pixel and the sub-pixel are made for every other pixel.

  • Publication number: 20120169790
    Abstract: 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).
