Abstract
An adaptive compensation system for aspect ratio conversion. Video information, intended for her first aspect ratio display, e.g. the standard NTSC aspect ratio, is processed to determine additional information that can enable that video to be displayed and fill a wider aspect ratio screen. The processing can be a calculation which calculates, for example, texture, color and/or brightness of the edge portions, and automatically calculates video information to match the texture, brightness or color. The processing can be a database lookup, which automatically looks up likely portions from a database. The processing can also be an adaptive determination of what vertical portions of the image can be stretched without affecting the viewability, and then an adaptive stretching of different portions by different amounts.
Claims15
An apparatus, comprising:
- a display, and a processing element, which receives video information as an input thereto, said video information having a first ratio between length and width of the video information, and said processing element operating to automatically determine additional video information for display on the display with a second, different ratio between length and width than said first ratio, wherein said processing element processes at least a portion of the video information to determine information indicative of at least a first characteristic of the video information in at least said portion, said first characteristic being a viewable characteristic that effects the look of the video information when displayed, and where said processing element automatically determines said additional video information having a determined characteristic related to said information indicative of said at least said first viewable characteristic, wherein said first characteristic is a first texture in at least said portion, and where said processing element automatically determines said additional video information having a determined texture related that matches to said first texture.
A method of displaying a video, comprising:
- receiving video information having a first ratio of length to width into a video device;
- and
- automatically determining additional video information for display on a display with a second, different ratio between length and width than said first ratio, said automatically determining obtaining information indicative of at least a first characteristic of the video information in at least a portion of said video information, said first characteristic being a viewable characteristic that effects the look of the video information when displayed, and where said additional video information has a non-constant luminance, but has an average luminance that is matched to an average luminance of a portion of said video information;
- and displaying said video information and said additional video information on said display device wherein said additional video information is obtained by accessing a database of additional video information using said information indicative of said viewable characteristic,
- said additional video information being selected from said database based on said information indicative of said viewable characteristic, wherein said first characteristic is a first texture in at least said portion, and said automatically determines obtains said additional video information from said database having a determined texture that matches to said first texture.
An apparatus, comprising:
- a connection to a display, and a processing element, which receives video information as an input thereto, said video information having a first ratio between length and width of the video information, and said processing element operating to automatically determine additional video information for display on the display with a second, different ratio between length and width than said first ratio, wherein said processing element processes at least a portion of the video information to determine information indicative of at least both of a color in said portion and a texture in said portion, and where said processing element automatically determines said additional video information having at least one characteristic that matches to both said color and said texture and outputs said additional video information on said connection.
