Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.

Systems, methods and apparatuses are described herein that allow an enterprise to analyze and manage work product images that are stored on a mobile device. Employees of an enterprise may use a mobile device to store both work product images (e.g., images of sensitive or proprietary information) and non-work product images (e.g., personal images).
