Image-data processing device and image-data processing method

An image data processing device for generating output image data which represents a stereoscopic output image including a first region image to be displayed in a first region and a second region image to be displayed in a second region adjacent to the first region, comprising:

• an extractor configured to extract a part of first image data representing a first image as first extraction data, which represents the first region image, and a part of second image data, which represents a second image to be viewed and compared simultaneously with the first image, as second extraction data representing the second region image,
• wherein the first image is one of a kit image to be viewed by a left eye and a right image to be viewed by a right eye,
• wherein the second image is another of the left and right images, and
• wherein the first image includes a first corresponding region in correspondence to the first region,
• wherein the second image includes a second corresponding region in correspondence to the second region.
• wherein the first corresponding region includes first strip regions extending in a predetermined direction,
• wherein the second corresponding region includes second strip regions extending in the predetermined direction,
• wherein the extractor alternately arranges the first and second strip regions,
• wherein the extractor incorporates boundary data into the output image data to show boundary lines indicating boundaries between the first and second regions to define strip image groups,
• wherein the extractor incorporates measurement image data into the output image data, the measurement image data representing a measurement image for measuring a deviation amount between the left and right images,
• wherein each of the strip image groups includes one of the first strip regions and one of the second strip regions, and
• wherein the strip image groups are arranged in regions segmented by the boundary lines, respectively.
