Embodiment Construction

[0043] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In addition, this embodiment is an example of a specific technical solution when the gloss judging device of the present invention is applied to a device for judging the skin condition of a user's face.

[0044]

[0045] figure 1 It is a figure which shows an example of the appearance and usage state of the glossiness determination apparatus 100 which concerns on one Embodiment of this invention.

[0046] like figure 1 As shown, the gloss judging device 100 is, for example, a tablet-type terminal that can stand on a table. In the gloss evaluation device 100 , a lamp 120 with a polarization filter, a camera 130 with a polarization filter, and a display 140 with a touch panel are arranged on the main surface of a plate-shaped housing 110 . The user 200 adjusts the position of the display with touch panel 140 and his / her own position so that the face 210 is...

Abstract

The present invention provides a gloss judging device and a gloss judging method capable of simply and accurately judging the gloss state of an object. The gloss judging device (100) has: an image acquiring unit (330) that acquires a parallel polarized light image and a cross polarized light image, wherein the parallel polarized light image is obtained by passing an object irradiated with polarized light through polarized The cross-polarized light image is an image in which polarization components in the same direction pass through a polarization filter. The cross-polarized light image is obtained by passing an object irradiated with polarized light through polarization components in a direction perpendicular to the polarization direction of the polarized light. An image obtained by shooting through the polarizing filter; a difference image generating unit (340) that generates a difference image representing a difference in luminance between the parallel polarized light image and the cross polarized light image; and a gloss judging unit (350 ), which determines the gloss state of the object based on the difference image.

Description

technical field [0001] The present invention relates to a gloss judging device and a gloss judging method for judging the gloss state of a face or the like. Background technique [0002] On the surface of an object, sheen is sometimes produced due to the balance of the state of the surface and the lighting situation. In the case of the face, strong gloss is called "reflective" etc. [0003] For example, when determining the presence or absence of skin conditions such as wrinkles based on an image of a face, if the influence of gloss is not considered, the determination accuracy may decrease. In addition, conversely, the skin condition such as the level of sebum can also be judged from the luster produced by the skin. Therefore, judging the state of the gloss such as the intensity and distribution of the gloss (hereinafter referred to as "glossy state") is useful in judging the state of the skin and the like. [0004] Therefore, for example, Patent Document 1 to Patent Doc...
