A vehicle lamp system (1) is provided with: a calculation unit (10) that extracts an index value from a prescribed processing target region in an image (IMG); a pattern determination unit (12) that determines a light distribution pattern (PTN) so that the index value approaches the maximum value; and a lamp control unit (14) that controls the variable light distribution lamp (2) to form a light distribution pattern (PTN). The index value is at least one of the average intensity of HOG feature amounts in a plurality of pixels in the processing target region and an edge gradation ratio, which is the ratio of pixels belonging to the gradation of the edge portion in an LBP (Local Binary Pattern) histogram of the plurality of pixels with respect to the whole of the plurality of pixels.

    车辆用灯具系统(1)具备:从图像(IMG)中的规定的处理对象区域提取指标值的运算部(10);以使指标值接近最大值的方式决定配光图案(PTN)的图案决定部(12);以及控制配光可变灯(2)以形成配光图案(PTN)的灯控制部(14)。指标值是处理对象区域的多个像素中的HOG特征量的平均强度以及在多个像素的LBP(Local Binary Pattern:局部二值模式)直方图中属于边缘部分的灰度的像素相对于多个像素的整体所占的比例即边缘灰度比例的至少一者。
