PROBLEM TO BE SOLVED: To provide a device, method and program for measuring light distribution of a light source.SOLUTION: A light distribution measurement device includes: imaging means of imaging an object having known reflection characteristic in a state of being illuminated by a light source, and acquiring an actual value of a sensor response value; sensor response value calculation means of calculating a calculation value of the sensor response value on the basis of a positional relationship between a shape model of the light source and the object, and a light distribution model; difference calculation means of calculating a difference between the actual value and calculation value of the sensor response value; and parameter estimation means of optimizing a parameter of the light distribution model as a target, and estimating a parameter for making the difference minimum.
