  • DISPLAY DEVICE
    Publication number: 20100149136
    Abstract: In a display device, when a first image is an absolute white image, a direction in which a luminance is maximum is regarded as a main viewing direction for the first image. A luminance Ld in the main viewing direction for the first image in cases where the first image is an absolute black image and other image is an absolute white image, and a luminance Lb in the main viewing direction for the first image in cases where the first image and the other image are absolute black images satisfy a relationship represented by Formula (1): (Ld?Lb)/Lb?2.5??(1). This makes it possible to realize a display device, which is capable of displaying different images to a plurality of different viewpoints and has an improved function of separating the images in the different display directions.

  • Display Device, Liquid Crystal Monitor, Liquid Crystal Television Receiver, and Display Method
    Publication number: 20100149227
    Abstract: A display device displaying an image by dividing each frame into subframes. A display section has pixels each containing a first subpixel (SP1) and a second subpixel (SP2) which are connected to the same source line (S) and the same gate line (G). A difference is created between the luminance of the first subpixels and the luminance of the second subpixels. Either the first or the second subpixels are driven for black (white) display, and the luminances of the other subpixels is adjusted, to display a low (high) luminance image. Thus, the discrepancy between the display luminance of either the first or the second subpixels and the actual luminance is minimized for improved viewing angle characteristics. The relationship between the levels of the luminances of the first and second subpixels (SP1, SP2) is changed every period. A user is less likely to see a screened pattern of bright dots and dark dots.

  • DRIVING METHOD FOR ZOOM LENS DEVICE, IMAGE PICKUP DEVICE USING THE METHOD, AND MOBILE INFORMATION DEVICE
    Publication number: 20100149382
    Abstract: When focal lengths are discretely set, zoom positions are set, relative to a focal length fr at a position at which a movement direction of a correction group, is reversed, such that a difference value between a focal length which is the closest to the focal length fr and falling between a focal length fw at a wide angle end and the focal length fr, and a next focal length is larger than a difference value between any remaining adjacent focal lengths. By moving from the zoom position of the closest focal length directly to the zoom position of the next focal length, a movement range of the correction group can be made smaller than a movement range in the case where the lens position of the focal length fr is set as the zoom position.
