Abstract
Abstract The present invention relates to an image data processing apparatus for generating an image corresponding to a view point, which is constituted by multi view points image data hold means for holding a plurality of image data having mutually different positions as view points, corresponding point trace detection means for sequentially detecting a coefficient which defines a trace of mutually corresponding points among the multi view points image data and member for outputting the coefficient of each of a plurality of the corresponding point traces present in the multi view points image data.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
An image data processing apparatus for generating an image corresponding to a view point comprising: multi view points image data holding means for holding a plurality of images obtained by phototaking an object from a plurality of view points arranged in a left and right direction; corresponding point trace detection means for sequentially detecting a coefficient representing a relationship between view point positions and displaying positions of corresponding points being mutually corresponded among said multi view points image data; wherein the coefficient is used when images of view points different from the view points when said object is phototaken are reproduced; and means for outputting the coefficient of each of a plurality of the corresponding point traces present in the multi view points image data.
Claim 2
Dependent Claim
125 words
An image data processing apparatus for generating an image corresponding to a view point comprising: multi view points image data holding means for holding a plurality of images obtained by phototaking an object from a plurality of view points arranged in a left and right direction; corresponding point trace detection means for sequentially detecting a coefficient representing a relationship between view point positions and displaying positions of corresponding points being mutually corresponded among said multi view points image data; wherein the coefficient is used when images of view points different from the view points when said object is phototaken are reproduced; and means for outputting the coefficient of each of a plurality of the corresponding point traces present in the multi view points image data.
Claim 3
Dependent Claim
41 words
An apparatus according to claim 1, wherein said corresponding point trace detection means comprises means for detecting a coefficient which defines a straight line as the corresponding point trace on an epipolar plane image of the multi view points image data.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 1, wherein said corresponding point trace detection means comprises means for detecting a coefficient which defines a plane as the mutually corresponding point trace among the multi view points image data.
Claim 5
Dependent Claim
120 words
An image reproduction apparatus for reproducing an image in correspondence with a view point, comprising: coefficient input means for inputting a coefficient representing a relationship between view point positions and a displaying positions of corresponding points being mutually corresponded among a plurality of images obtained by phototaking an object from a plurality of view points arranged in a left or right direction; means for inputting a view point position including a view point position different from the view point positions of said plurality of image data; image interpolation generation means for generating an image corresponding to the inputted view point position by interpolation on the basis of the coefficient; and means for outputting the generated image to a display device.
Claim 6
Dependent Claim
120 words
An image reproduction apparatus for reproducing an image in correspondence with a view point, comprising: coefficient input means for inputting a coefficient representing a relationship between view point positions and a displaying positions of corresponding points being mutually corresponded among a plurality of images obtained by phototaking an object from a plurality of view points arranged in a left or right direction; means for inputting a view point position including a view point position different from the view point positions of said plurality of image data; image interpolation generation means for generating an image corresponding to the inputted view point position by interpolation on the basis of the coefficient; and means for outputting the generated image to a display device.
