Title:
紋様画像取得装置、表示装置及びコリメート部材
Document Type and Number:
Japanese Patent JP7425002
Kind Code:
B2
Abstract:
A texture image acquiring device, a display device and a collimator are disclosed. The texture image acquiring device (10) includes a collimator (110) and an image sensor (120). The collimator (110) includes a lens array (111), a first diaphragm layer (112), and a second diaphragm layer (113). The lens array (111) is configured to allow light rays to be converged and incident on the first diaphragm layer (112). The first diaphragm layer (112) is configured to allow light rays incident on the first diaphragm layer (112) to pass through and be incident on the second diaphragm layer (113), and to restrict an angle of light rays capable of passing through the first diaphragm layer (112). The second diaphragm layer (113) is configured to allow light rays incident on the second diaphragm layer (113) to pass through, and to restrict an angle of light rays capable of passing through the second diaphragm layer (113). The image sensor (120) is configured to sense light rays incident on the image sensor (120) for acquiring a texture image. The texture image acquiring device (10) has a light and thin structure, and can improve the accuracy of the acquired texture image.
