A vehicle headlight device capable of outputting various light distribution patterns with low power consumption is provided. The vehicle headlight device (1) includes: an array light source (5) configured to have a plurality of light-emitting elements arranged therein; a condensing lens (7) which condenses light output from the array light source (5); a light source control unit (13) which individually changes light emission volumes of the plurality of light-emitting elements; a digital mirror (8) which reflects, with a plurality of mirror elements, light entering from the condensing lens (7); a projector lens (9) which projects, in a irradiation region (S), a light distribution pattern of the light reflected on the digital mirror (8); and a control device (3) which controls the light emission volumes of the plurality of light-emitting elements and inclined forms of the mirror elements to change illuminance distribution of the light distribution pattern.
