5. The apparatus according to claim 4 , wherein
the program causes the processor to:
adjust the light source such that the first light amount is made to be a light amount at which a luminance of an image captured by the capturing unit is saturated in a region of an image formed using metallic color ink and is not saturated in another region, and the second light amount is made to be a light amount that is not saturated in a region of an image formed using metallic color ink, and
capture the image by the capturing unit.
6. The apparatus according to claim 4 , wherein the program causes the processor to determine the second light amount based on information extracted from the image captured at the first light amount.
7. The apparatus according to claim 4 , wherein
the program causes the processor to:
adjust the light source to the first light amount by the adjustment unit,
capture the image by the capturing unit,
extract the information by the extraction unit, and
in a case where the information is extracted or a case where the information is not extracted after a predetermined number of attempts, adjust the light amount of the light source to a second light amount that is smaller than the first light amount.
8. 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.
9. The non-transitory computer readable medium according to claim 8 , wherein the at least program causes the computer to:
adjust the light amount of the light source to a light amount that accords with each of a plurality of reflection intensities by an adjustment unit,
capture the image at the light amount that accords with each of the plurality of reflection intensities by the capturing unit, and
extract information from each image.
10. The non-transitory computer readable medium according to claim 8 , wherein the at least program causes the computer to:
capture the image by the capturing unit for each adjustment of the light source to a different light amount by the adjustment unit, and
extract information by an extraction unit.
11. The non-transitory computer readable medium according to claim 8 , wherein the at least program causes the computer to:
adjust the light source to a first light amount by an adjustment unit,
capture the image by the capturing unit,
extract information by an extraction unit, and
adjust the light amount of the light source to a second light amount that is smaller than the first light amount.
12. The non-transitory computer readable medium according to claim 11 , wherein the at least program causes the computer to:
adjust the light source such that the first light amount is made to be a light amount at which a luminance of an image captured by the capturing unit is saturated in a region of an image formed using metallic color ink and is not saturated in another region, and the second light amount is made to be a light amount that is not saturated in a region of an image formed using metallic color ink, and
capture the image by the capturing unit.
