Description

  The present invention relates to a technique for performing color reproduction processing on display data of a picture using rendering illumination data.

  In recent years, in electronic museums and homes, there are an increasing number of cases where a user views a digitalized picture on a display. By appropriately processing the rendering illumination for the image data of the painting, color reproduction can be performed as if the image is viewed under a desired illumination. The rendering illumination is a spectral characteristic of illumination that is multiplied by the spectral reflectance of the subject estimated by removing the influence of the illumination at the time of photographing when generating the spectral data of the subject. Hereinafter, the rendering illumination data is referred to as rendering illumination data or simply illumination data.

  In the case of viewing a picture on the display, the visual effect of actually viewing a picture at the museum can be obtained by reproducing the lighting of the museum where the actual picture is displayed. For this purpose, it is assumed that the rendering lighting data of the museum is provided, and it is expected that the rendering lighting data for reproducing the lighting of the museum is added to the expensive painting data. However, in the case of existing picture data or inexpensive picture data, rendering lighting data may not be added to all picture data. On the other hand, it is expected that art information such as the name of the museum and the location of the museum will be added to the painting data in addition to the name of the work and the name of the author. In the case of painting data to which rendering lighting data is not added, in order to reproduce the lighting of the museum in which the actual painting is exhibited, it is necessary to specify appropriate rendering lighting from the museum information. As a method for specifying lighting data, Patent Document 1 discloses searching for lighting data associated with a data category (news, traffic, weather, etc.) and controlling actual lighting. Japanese Patent Application Laid-Open No. 2004-228561 discloses that the illumination at the time of photographing is reproduced by color processing using the illumination data at the time of photographing and the illumination data at the time of reproduction.

Special table 2009-535676 JP-A-9-172649

In Patent Document 1, the lighting effect can be changed depending on the category, but the lighting in the actual place is not reproduced by specifying the lighting data of the museum using the museum information such as the museum name and the museum location. In addition, actual illumination light data is a target, and rendering illumination data for color reproduction processing is not specified.
In Patent Document 2, illumination at the time of photographing is reproduced using illumination data at the time of photographing added to an image. However, if no illumination data is added to the image, the illumination at the time of shooting cannot be reproduced by color processing.
In view of this, the present invention specifies color rendering processing using rendering information including painting information including the name of a painting work or the location where the painting is displayed, with respect to display data of a painting to which rendering lighting data is not added. The purpose is to do.

  In order to solve the above problems, an apparatus according to the present invention is a display device that displays an image by processing display data of a painting and rendering illumination data used for color reproduction processing of the display data. Or, information acquisition means for acquiring painting information including information on the location where the painting is exhibited, management means for managing rendering illumination data in association with the painting information, and rendering lighting data corresponding to the painting information. Specifying means for specifying, and color processing means for performing color reproduction processing of the display data using rendering illumination data specified by the specifying means. When the rendering lighting data is not added to the display data of the painting, the specifying unit searches the rendering lighting data managed by the management unit using the painting information acquired by the information acquisition unit, thereby Specify rendering lighting data corresponding to the information.

  According to the present invention, with respect to the display data of a painting to which no rendering lighting data is added, the rendering lighting data is specified by using the painting information including the name of the work of the painting or the location information where the painting is displayed, and color reproduction is performed. Processing can be performed.
