An image processing apparatus includes a print section configured to perform printing on a recording medium, a first detector configured to detect a moving object within a first detection range, a second detector configured to detect the moving object within a second detection range, and a controller configured to switch between a normal mode in which printing by the print section is enabled and a power-saving mode in which printing by the print section is disabled. The controller returns to the normal mode when, after the controller enters the power-saving mode, in response to detection of the moving object by the first detector or the second detector, the first detector or the second detector detects the moving object for a first predetermined period of time or more, and the first detector and the second detector detect the moving object for a second predetermined period of time or more.

Provided for is a film conversion apparatus comprising a body and a first reel shaft having a first proximal end and a first distal end. A first reel may be disposed on the first distal end. The apparatus may include a second reel shaft having a second proximal end and a second distal end, where the first proximal end and the second proximal end are movably attached to the body. A second reel may be disposed on the second distal end. The apparatus may further include a camera configured to capture a plurality of frames and a computer configured to convert the plurality of frames to a digital format.

A projection system, including a projection target, a projection device, an image capturing device, and a processor circuit, is provided. The projection target includes a reflective surface and an anti-reflective film disposed on the reflective surface. The anti-reflective film defines a projection range. The image capturing device captures a first captured image containing the projection target. The first captured image includes an image of the anti-reflective film. The processor circuit determines a position and a shape of the anti-reflective film in the first captured image according to the first captured image. The projection device projects a projection image on the projection target. The projection device adjusts the projection image according to the position and the shape of the anti-reflective film, and correspondingly adjusts the projection image to the projection range. In addition, an image projection method is also provided.
