Abstract
An apparatus comprises at least one processor; at least one memory storing at least one program; a light source; and a capturing unit configured to acquire image data by capturing an image formed on a medium, wherein the program, when executed by the processor, causes the processor to extract information multiplexed in the image from an image captured by the capturing unit, adjust the light amount of the light source to a light amount that accords with a reflection intensity of the medium on which the image is formed, capture the image, and extract information from the image.
Claims17
An apparatus comprising:
- at least one processor;
- at least one memory storing at least one program;
- a light source;
- and
- a capturing unit configured to acquire data by capturing an image formed on a medium, wherein
- the program, when executed by the processor, causes the processor to:
- adjust a light amount of the light source to a light amount that accords with a reflection intensity of the medium on which the image is formed, the reflection intensity being determined by at least one of whether there is the image formed using metallic color ink and a type of the medium,
- capture the image, and
- extract information multiplexed in the image from the image.
A non-transitory computer readable medium storing at least one program, when executed by a computer comprising a light source, an adjustment unit configured to adjust a light amount of the light source, and a capturing unit configured to acquire image data by capturing an image formed on a medium, causes the computer to:
- adjust the light amount of the light source to a light amount that accords with a reflection intensity of the medium on which the image is formed, the reflection intensity being determined by at least one of whether there is the image formed using metallic color ink and a type of the medium,
- capture the image, and
- extract information multiplexed in the image from the image.
A method by an apparatus comprising:
- a light source;
- an adjustment unit configured to adjust a light amount of the light source;
- and
- a capturing unit configured to acquire image data by capturing an image formed on a medium, the method comprising:
- adjusting the light amount of the light source to a light amount that accords with a reflection intensity of the medium on which the image is formed, the reflection intensity being determined by at least one of whether there is the image formed using metallic color ink and a type of the medium,
- capturing the image, and
- extracting information multiplexed in the image from the image.
