Vehicle headlight system

There is provided a vehicle headlight system (100) comprising: a lamp unit (10) configured to selectively illuminate a front region in front of a vehicle with a one of a plurality of light distribution patterns; a capturing unit (102) configured to capture image frame data of the front region, the image frame data including the light distribution pattern; a light blocking storage unit (106) configured to store light blocking information in which light blocking regions of each light distribution patterns is associated with each light distribution pattern; an extraction processor (104) configured to extract a target object in the image frame data; and a controller (302) configured to select a light distribution pattern, wherein when the extraction processor (104) extracts the target object in the image frame data, the controller (302) selects a light distribution pattern that is capable of suppressing glare directed to the target object, and wherein the extraction processor (104) sets a region of interest in a light blocking region based on the light blocking information.
