An image recognition device, an image recognition method, and an image recognition unit which can achieve touch recognition with high accuracy. An image recognition device includes an image processing unit which carries out touch recognition, based on an image acquired by an image capturing device, the image capturing device being arranged in a second orthant or a third orthant, and based on a distance between a missing part generated on an image display surface due to light from a detection image display device being blocked by an object when the object is situated between the detection image display device and the image display surface, and the detection image situated on an epipolar line decided based on a positional relation between the image capturing device and the detection image display device and passing through the missing part, and displayed on the object.
