Image acquisition system

A display device comprising:

• a display surface on which a subject can be placed, the display surface including an illumination region that generates illumination light and a display region;
• a reception unit that receives an image transmitted from an image acquisition device which is disposed face-down at a position above the display device in a manner spaced apart from the display surface, the display device being disposed with the display surface face-up, and which acquires an image of the display surface and an image of the subject placed on the display surface;
• a relative-position calculation unit that calculates a relative position between the display device and the image acquisition device;
• and
• a display control unit that performs control to display the received image on the display region and that adjusts a position or a size of the illumination region on the basis of the calculated relative position.

A display method of a display device which comprises a display surface on which a subject can be placed, the display surface including an illumination region that generates illumination light and a display region, the method including:

• receiving an image transmitted from an image acquisition device which is disposed face-down at a position above the display device in a manner spaced apart from the display surface, the display device being disposed with the display surface face-up, and which acquires an image of the display surface and an image of the subject placed on the display surface;
• calculating a relative position between the display device and the image acquisition device;
• and
• performing control to display the received image on the display region and adjusting a position or a size of the illumination region on the basis of the calculated relative position.

A non-transitory computer readable medium in which a program of a display device is recorded, the display device comprising a display surface on which a subject can be placed, the display surface including an illumination region that generates illumination light and a display region, the program causing the display device to execute:

• receiving an image transmitted from an image acquisition device which is disposed face-down at a position above the display device in a manner spaced apart from the display surface, the display device being disposed with the display surface face-up, and which acquires an image of the display surface and an image of the subject placed on the display surface;
• calculating a relative position between the display device and the image acquisition device;
• and
• performing control to display the received image on the display region and adjusting a position or a size of the illumination region on the basis of the calculated relative position.
