US 11,908,432 B2 · Apparatus and method for automatically controlling screen brightness of AVN system

Abstract

An apparatus and a method for automatically controlling a screen brightness of an AVN system are provided to automatically change screen brightness in a user customized manner in a response to a change in illumination outside the vehicle. The apparatus include a screen brightness control module that controls such that a screen brightness of a display provided in the AVN system is automatically changed according to a change in the illumination data received from the illumination sensor, based on a default matching relationship between previously stored illumination data and screen brightness and a gain adjustment module that generates a new customized matching relationship by correcting the screen brightness matched to each illumination data based on the default matching relationship in accordance with an input of a user who adjusts to enhance or weaken the screen brightness and provides the screen brightness control module with the new customized matching relationship for screen brightness control.

Dependent claims

An apparatus for automatically controlling a screen brightness of an audio video navigation (AVN) system, the apparatus comprising:

an illumination sensor configured to measure illumination outside a vehicle per a predetermined period;
an illumination data receiving device configured to receive illumination data transmitted per the predetermined period from the illumination sensor and determine an average of a predetermined number of the received illumination data;
a per-illumination brightness controller configured to determine target screen brightness matched to the average of the illumination data, the average being determined by the illumination data receiving device, from a previously stored default matching relationship;
and
a display configured to control a screen brightness based on the target screen brightness, and
wherein the per-illumination brightness controller is configured to determine the target screen brightness based on a new customized matching relationship which is generated by correcting the screen brightness matched to each illumination data based on the default matching relationship in accordance with an input of a user who adjusts to enhance or weaken the screen brightness.

A method for automatically controlling a screen brightness of an audio video navigation (AVN) system, the method comprising:

receiving at least one illumination data measured per a predetermined period by an illumination sensor;
controlling so that a screen brightness of a display provided in the AVN system is automatically changed according to a change in the illumination data received from the illumination sensor, based on a default matching relationship between the illumination data and the screen brightness;
generating a new customized matching relationship by correcting the screen brightness matched to each illumination data based on the default matching relationship in accordance with an input of a user who adjusts to enhance or weaken the screen brightness and providing the new customized matching relationship for screen brightness control;
and
performing dimming control so that screen brightness is changed on a stage-by-stage basis by a predetermined ratio per a predetermined period, in automatically changing a screen brightness degree depending on the change in the illumination data using the default matching relationship or a customized matching relationship.
