  • Patent number: 8498530
    Abstract: A detection apparatus determines whether an output of the light-receiving unit meets a predetermined reference level when the light emission amount of the light-emitting unit is changed, under a condition that the output of the light-receiving unit changes according to a change in a light emission amount of the light-emitting unit. The detection apparatus detects, based on the output from the light-receiving unit, that the light emitted from the light-emitting unit to the light-receiving unit is blocked, under a condition that the light-emitting unit is emitting light based on a light emission amount emitted from the light-emitting unit when it has been determined that the output of the light-receiving unit meets the predetermined reference level.

  • Patent number: 7024109
    Abstract: Sound information related to an image is inputted together with the image taken by a camera, and is printing outputted as a two-dimensional bar code data with the image by a printer provided in the camera as one body. Specifically, a printed matter is formed by printing the taken image and the sound information sound inputted in relation to the image. Thereby, the printed matter is printed with a comment on image taking environment such as information on a subject of image taking and a light condition when taking the image or on the subject of the image taking inputted through the sound. As a result, it can be used as a storage medium which stores information of higher dimension and is easy to access.
