Motion detection analyzes the image trace displayed in the preview screen of a mobile camera. Then, it recognizes which direction and how much a camera has moved precisely and changes the recognition result into commands. Overview Application Specification
It recognizes the following movements of camera and changes them into commands. (The movement of “backward and forward” and “Horizontal rotation” are being developed.)
The engine detects camera motions from images during photography and converts them into commands.
・Vertical and Horizontal movement to the camera face
・Backward and forward movement to the camera face (Under development)
・Horizontal rotation to the camera face (Under development)
・Tilting rotation to the camera face.
*Please see exhibit for details.
Recognition processing speed
15fps (Value on ARMS7)

No 1 adoption of barcode scanner for mobile phone in Japan. Offered to major 3 carriers (KDDI, NTT DoCoMo, vodafone) in Japan. Supports various symbol like QR code, EAN, UPC, Datamatrix etc. Is an excellent image processing software.
It is an innovative image processing software, which recognizes alphanumeric and symbols with the mobile phone.
The application for motion detection analyzes the image trace displayed on the preview image of a mobile phone. Then, it recognizes to which direction and how much a camera has moved precisely and changes the recognition result into commands.
