1. A receiving method comprising:
- setting a first exposure time for at least one exposure line of exposure lines in an image sensor, and setting a second exposure time for a remainder of the exposure lines in the image sensor, the second exposure time being shorter than the first exposure time;
causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines in the image sensor with the second exposure time, the bright line image including a plurality of bright lines, each of which corresponds to a different one of the remainder of the exposure lines in the image sensor; and
obtaining information by decoding a pattern of the plurality of the bright lines included in the obtained bright line image.

Abstract
A receiving method includes: setting a first exposure time for at least one exposure line of exposure lines in an image sensor, setting a second exposure time for a remainder of the exposure lines in the image sensor, and causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines with the second exposure time. The second exposure time is shorter than the first exposure time. The bright line image includes a plurality of bright lines, each of which corresponds to a different one of the remainder of the exposure lines in the image sensor. Information is obtained by decoding a pattern of the plurality of the bright lines included in the obtained bright line image.

7. An apparatus comprising:
-
a processor; and a memory storing a computer program, the computer program causing the processor to execute operations including; setting a first exposure time for at least one exposure line of exposure lines in an image sensor, and setting a second exposure time for a remainder of the exposure lines in the image sensor, the second exposure time being shorter than the first exposure time; causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines in the image sensor with the second exposure time, the bright line image including a plurality of bright lines, each of which corresponds to a different one of the reminder of the exposure lines in the image sensor; and obtaining information by decoding a pattern of the plurality of the bright lines included in the obtained bright line image.

8. A non-transitory recording medium having a computer-program stored thereon, the computer program causing a processor to execute operations comprising:
-
setting a first exposure time for at least one exposure line of exposure lines in an image sensor, and setting a second exposure time for a remainder of the exposure lines in the image sensor, the second exposure time being shorter than the first exposure time; causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines in the image sensor with the second exposure time, the bright line image including a plurality of bright lines, each of which corresponds to a different one of the remainder of the exposure lines in the image sensor; and obtaining information by decoding a pattern of the plurality of the bright lines included in the obtained bright line image.
