Image information is reproduced in respectively correspondence to monitors of different aspect ratios as in the NTSC system or HDTV system adaptive type. The image information recorded on a video disc is reproduced. An ID signal held in the video disc is detected. The aspect ratio of the image information to be generated is designated. Only when the aspect ratio indicated by the detected ID signal differs from the designated aspect ratio, the reproduced image information is converted into the image information of the designated aspect ratio. A standardized image signal is produced on the basis of the converted image information.

The image is then provided to a display. In another aspect, the method and system include cropping an image to a predetermined shape and providing the data to a display buffer.

Disclosed is a liquid crystal display device, which is capable of reducing a required response speed and increasing a pixel aperture ratio, as compared with a field sequential driving scheme. A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image.

The invention is directed to provide a virtual image display device capable of setting the aspect ratio of the image light entering the eyes of the observer as a virtual image to a desired state while fulfilling the design limitations. In the invention, the aspect ratio of the virtual image can be converted to the aspect ratio (16:9) laterally longer than the aspect ratio (4:3) of the image area due to the conversion in the aspect ratio conversion optical system. Thus, the aspect ratio of the image light to be recognized by the eye of the observer as a virtual image can be adjusted to a desired state even in the case in which, for example, the lateral width of the image forming device with respect to the whole of the virtual image display device is limited by a design requirement.

A method and apparatus for dynamically adjusting an aspect ratio of an image during a video call is described herein. Specifically, a method for dynamically adjusting the aspect ratio of an image during a video call may include obtaining at least one display parameter of a display device, performing a comparison of the at least one display parameter to at least one image capture parameter of a capture device, capturing an original image, modifying the original image based on the comparison performed, wherein the modified image has an adjusted aspect ratio different from an aspect ratio of the original image, and sending the modified image to the display device.

According to the invention, a video distribution system is disclosed. The video distribution system distributes a video program in a first aspect ratio and includes information to convert the first aspect ratio to a second aspect ratio. Included in the video distribution system are a distribution point and a video converter that is located remotely from the distribution point. The video converter receives the information and the video program from the distribution point. The video converter uses the information to guide conversion between the first aspect ratio and the second aspect ratio.

A system that intelligently manages the empty spaces on a digital television screen when video images other than the native aspect ratio of the screen are being displayed. These spaces are typically presented as black bars on either side and/or above and below a video image that is not the same aspect ratio as the aspect ratio that is native to the display screen. The invention allows for non-contrasting bars to minimize burning of the bar image onto screens that are susceptible to retention of a high contrast image. The invention also allows for the display of metadata such as current program related information and other data that may be of interest to the viewer.
