Abstract: An document camera used by being connected to a display apparatus is provided. The document camera includes a plurality of imagers, an image processing unit that produces two sets of image data by using two of the plurality of imagers to capture images of a single target object from different imaging positions, a parameter acquisition unit that acquires a parameter for determining an inter-image distance between the two sets of image data to be displayed by the display apparatus, and an output unit that outputs the two sets of image data and the parameter or the inter-image distance to the display apparatus.
