    • A display device convertible between two-dimensional (2D) and three-dimensional (3D) is provided. The convertible display device is based on integral imaging (II) or integral photography (IP) and displays 2D or 3D images. An image processor generates and transmits elemental images to reconstruct a 3D image or transmits a desired two-dimensional image, and a transmission-type display device displays the image received from the image processor. At this time, a diffusion rate (or haze rate) of light illuminated from a point light source array that is made of a plurality of point light sources is controlled by a variable diffuser and as the light illuminates the transmission-type display device, the device displays 2D or 3D images. According to the present invention, a point light source array is generated by controlling a variable diffuser and as a result a display device convertible between 3D and 2D is achieved. Moreover, a 3D image can be made by spatially modulating the light illuminated from a point light source array and, thereby, an available depth region is dramatically improved.
    • 提供了可在二维(2D)和三维(3D)之间转换的显示设备。 可转换显示设备基于积分成像(II)或积分摄影(IP),并显示2D或3D图像。 图像处理器生成并发送元素图像以重构3D图像或发送期望的二维图像,并且传输型显示设备显示从图像处理器接收的图像。 此时,由多个点光源构成的点光源阵列照射的光的扩散率(或雾度)由可变扩散器控制,并且当光照射透射型显示装置时, 设备显示2D或3D图像。 根据本发明,通过控制可变扩散器来产生点光源阵列,结果实现了在3D和2D之间可转换的显示装置。 此外,可以通过空间调制从点光源阵列照射的光来制造3D图像,从而显着改善可用的深度区域。
