Abstract
An imaging apparatus according to an implementation of the present invention includes: an imaging device unit which converts light coming from an object into an image signal, the light being illuminating light reflected off an object; a light pattern detecting unit which detects a light-dark pattern from the image signal so as to detect information overlaid on the illuminating light, the image signal being converted from the light by the imaging device unit; a comparing unit which compares detection information with predetermined determination information, the detection information being the information detected by the light pattern detecting unit; and a display unit which displays a specific image, depending on a result of the comparison by the comparing unit.
Claims20
An apparatus comprising:
- an imaging device unit configured to receive light which comes from an object and on which information is overlaid, and convert the light received into an image signal, the information having a particular meaning represented by a light intensity of the light which varies over time;
- a light pattern detecting unit configured to detect a light-dark pattern by generating a luminance signal based on a data item made of color components, so as to detect the information overlaid on the light, the data item being outputted from the imaging device unit;
- and
- a display unit configured to perform a specific display, depending on a result of a comparison between the information detected by the light pattern detecting unit and predetermined determination information.
A system comprising:
- an illuminating apparatus which emits light on which information is overlaid, the information having a particular meaning represented by a light intensity of the light which varies over time;
- an object subject to the light on which the information is overlaid;
- and
- an apparatus which receives light which comes from the object, the received light including the light on which the information is overlaid,
- wherein the apparatus includes:
- an imaging device unit configured to convert the light which comes from the object into an image signal;
- a light pattern detecting unit configured to detect a light-dark pattern by generating a luminance signal based on a data item made of color components, so as to detect the information overlaid on the light, the data item being outputted from the imaging device unit;
- and
- a display unit configured to perform a specific display, depending on a result of a comparison between the information detected by the light pattern detecting unit and predetermined determination information.
