The invention provides a method and an apparatus for use with an imaging device weighing less than eight ounces, such as a lightweight digital camera or a camera-equipped cell phone, in conjunction with a base apparatus capable of locating and re-locate the imaging device relative to a built environment, and generating and displaying discontinuous time-lapse image sequences. The inventive apparatus provides for the rotation of the attached imaging device to capture a set of images that provide complete coverage of the items and features that are visible from the location of the apparatus or to duplicate an image taken from any compass heading and pitch reachable by the apparatus.

The present disclosure provides an optical invisible device. The optical invisible device sequentially comprises along an incident direction of an optical path: a first microlens array for imaging, an imaging unit, a display screen, and a second microlens array for projecting content displayed by the display screen to the outside, and further comprises an image processing unit. In addition, there is further provided another optical invisible device, which comprises: a first microlens array for imaging, a first imaging unit, a first image processing unit, a first display screen, and a second microlens array that are located at a first side, and a third microlens array, a second imaging unit, a second image processing unit, a second display screen, and a fourth microlens array that are located at a second side.

A X-ray film packaging bag printer is disclosed. A positioning detection device is arranged above a conveyor belt, positioning holes in an X-ray film packaging bag strip are detected by the positioning detection device, and positioning can be performed by only using adjacent two positioning holes.
