Benefits of technology

[0029]The adjusting may include, if the signal value is greater than the predetermined target value and a difference between the signal value and the predetermined target value is greater than or equal to a predetermined standard value, reducing light emitted from the light emitting element such that the difference decreases below the standard value, and when the difference is less than the standard value, decreasing the exposure level of the light receiving element.
[0030]The adjusting may include, if the signal value is less than the predetermined target value and a difference between the signal value and the predetermined target value is greater than or equal to a predetermined standard value, increasing light emitted from the light emitting element such that the difference decreases below the standard value, and once the difference is less than the standard value, increasing the exposure level of the light receiving element.
