Title:
A luminosity control device and the luminosity control method
Document Type and Number:
Japanese Patent JP6234362
Kind Code:
B2
Abstract:
A luminance control device and a luminance control method for controlling luminance of a light emitting member are provided in order to reduce the amount of information to be stored while preventing the user from feeling uncomfortable. The CPU divides by the interpolation division number a value obtained subtracting the reference duty ratio from the reference duty ratio so as to calculate an interpolation variation width, and integrates the interpolation variation width to the reference duty ratio every time the interpolation period elapses, and the variation width in the luminance of the LED is therefore reduced, preventing users to feel uncomfortable, which allows for suppressing the amount of information to be stored.
