Abstract
A reading device, a reading method and a reading program that can easily and quickly read a composite symbol, and a settlement processing method are provided. A moving image of a composite symbol which includes a plurality of symbols emerging in the same location and whose appearance changes depending on a viewing angle, is captured. The symbols included in the composite symbol are detected from the moving image obtained by image-capturing. Authenticity of the composite symbol is determined based on the obtained moving image.
Claims12
A reading device comprising
- at least one processor configured to:
- acquire a moving image captured while moving or changing an angle relative to a composite symbol in which a plurality of symbols appear in a switching manner depending on a viewing angle with a lenticular lens sheet or a microlens array sheet, each of the symbols being configured with a code, an emergence ratio of each of the symbols differing in a case where the composite symbol is viewed while continuously changing an angle at a constant speed;
- detect the symbols from the moving image;
- and
- determine authenticity of the composite symbol based on the emergence ratio of each of the symbols detected from the moving image.
A reading method comprising:
- acquiring a moving image captured while moving or changing an angle relative to a composite symbol in which a plurality of symbols appear in a switching manner depending on a viewing angle with a lenticular lens sheet or a microlens array sheet, each of the symbols being configured with a code, an emergence ratio of each of the symbols differing in a case where the composite symbol is viewed while continuously changing an angle at a constant speed;
- detecting the symbols from the moving image;
- and
- determining authenticity of the composite symbol based on the emergence ratio of each of the symbols detected from the moving image.
A non-transitory and computer-readable recording medium which records thereon a command which causes, when read by a computer, the computer to execute a reading function comprising:
- a function of acquiring a moving image captured while moving or changing an angle relative to a composite symbol in which a plurality of symbols appear in a switching manner depending on a viewing angle with a lenticular lens sheet or a microlens array sheet, each of the symbols being configured with a code, an emergence ratio of each of the symbols differing in a case where the composite symbol is viewed while continuously changing an angle at a constant speed;
- a function of detecting the symbols from the moving image;
- and
- a function of determining authenticity of the composite symbol based on the emergence ratio of each of the symbols detected from the moving image.
A settlement processing method based on a code, comprising:
- acquiring a moving image captured while moving or changing an angle relative to a composite symbol in which a plurality of symbols appear in a switching manner depending on a viewing angle with a lenticular lens sheet or a microlens array sheet, each of the symbols being configured with the code, an emergence ratio of each of the symbols differing in a case where the composite symbol is viewed while continuously changing an angle at a constant speed;
- detecting the symbols from the moving image;
- and
- determining authenticity of the composite symbol based on the emergence ratio of each of the symbols detected from the moving image.
