Abstract

Disclosed is a show case capable of managing and displaying objects stored therein. A show case according to one aspect of the present disclosure is a show case having an accommodation space in which an object is stored, and includes: a body; a moving body configured to form the accommodation space together with the body and including a transparent window; a blowing part configured to circulate air in the accommodation space; a first illumination configured to illuminate an object placed on a bottom surface of the accommodation space; a second illumination configured to illuminate a rear surface of the accommodation space; an input part to which an image of the object accommodated in the accommodation space is input; and a controller configured to recommend a type of second illumination to a user depending on the image input to the input part.

First claim

The invention claimed is:

1. A show case having an accommodation space in which an object is accommodated, the show case comprising:
a body;
a moving body configured to form the accommodation space together with the body and comprising a transparent window;
a blowing part configured to circulate air in the accommodation space;
a first illumination configured to illuminate an object placed on a bottom surface of the accommodation space;
a second illumination configured to illuminate a rear surface of the accommodation space;
an input part to which an image of the object accommodated in the accommodation space is input; and
a controller configured to recommend a type of second illumination to a user depending on the image input to the input part.

2. The show case according to claim 1 ,
further comprising a portable device having the input part and capable of remote communication with the controller,
wherein the image is captured by the portable device and input to the input part, and
wherein the type of second illumination recommended to the user by the controller is displayed on the portable device.

3. The show case according to claim 2 ,
wherein the portable device displays a reference line corresponding to outer lines of the body and the moving body when capturing the image.

4. The show case according to claim 3 ,
wherein the controller is configured to control the first illumination to illuminate the object when capturing the image through the portable device.

5. The show case according to claim 4 ,
wherein the image input through the input part is captured through the portable device and then dummy areas thereof are removed.

6. The show case according to claim 1 ,
wherein the second illumination is configured to change to any one of a plurality of preset illuminations that are set in advance, and
wherein the controller is configured to recommend at least one of similar color temperature illumination, similar monochromatic illumination, and similar spectrum illumination for the image from among the preset illuminations to the user.

7. The show case according to claim 6 ,
wherein the similar color temperature illumination is the preset illumination to be recommended according to an average color temperature of pixels whose brightness (value) is within an upper setting range in the image.

8. The show case according to claim 7 ,
wherein the similar monochromatic illumination is the preset illumination to be recommended according to a color with a highest proportion in a color palette reflecting pixels whose chroma is relatively high in the image.

9. The show case according to claim 8 ,
wherein the color palette is obtained by amplifying a number of pixels whose value ((a*) 2 +(b*) 2 ) 1/2 is greater than or equal to a first setting value in the image on three-dimensional coordinates defined by L*, a*, and b*, which are color spaces for color recognition, and then deriving a plurality of clusters therefrom using a clustering algorithm.

10. The show case according to claim 9 ,
wherein the controller is configured to recommend the similar monochromatic illumination in order of a shortest Euclidean distance from the color with the highest proportion in the color palette derived as a plurality of clusters.

11. The show case according to claim 10 ,
wherein the similar spectrum illumination is the preset illumination in a spectrum state to be recommended in order of the shortest Euclidean distance from the color with the highest proportion in the color palette.

12. The show case according to claim 11 ,
wherein, if the maximum value of the Euclidean distances between three colors with relatively high distribution in the color palette is greater than or equal to a second setting value, the colors included in the image are considered diverse.

13. The show case according to claim 12 ,
wherein the controller is configured to preferentially recommend rainbow-typed similar spectrum illumination if the colors included in the image are considered diverse or if an absolute values of a* and b* of the color with the highest proportion in the color palette are both smaller than a third setting value.

14. The show case according to claim 13 ,
wherein, if the value ((a*) 2 +(b*) 2 ) 1/2 of the color with the highest proportion in the color palette is less than or equal to a fourth setting value, the image is regarded as achromatic.

15. The show case according to claim 14 ,
wherein the controller is configured to preferentially recommend the similar color temperature illumination over the similar monochromatic illumination if the image is regarded as achromatic.

16. The show case according to claim 15 ,
wherein the controller is configured to recommend the similar spectrum illumination, regardless of the priority between the similar monochromatic illumination and the similar color temperature illumination.
