BRIGHTNESS FEELING PREDICTION DEVICE AND BRIGHTNESS FEELING PREDICTION PROGRAM

摘要

According to the present invention, a surface type setting unit (26) defines each image area corresponding to each surface included in a luminance image (20) representing a target space, and sets surface types of the defined plurality of image areas. A brightness feeling prediction unit (28) refers to weight information (22) in which weight indicating a degree of contribution to brightness feeling is associated with each surface type that can be defined in the luminance image (20), and predicts the brightness feeling of the target space represented by the luminance image (20), on the basis of a representative value of the brightness values of a plurality of pixels included in each image area (40) set by the surface type setting unit (26) and the weight of the surface type of each image area (40).
