Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing device, an image processing method, an imaging device, and a program, and relates to an image processing device, an image processing method, an imaging device, and a program that change image processing according to a length of an elapsed date and time from a time of imaging. 2. Description of the Related Art In the related art, a technique has been proposed in which predetermined processing is performed on an image to make a viewer more interested in the image. For example, Patent Document 1 discloses a technique in which, in a case where a plurality of image contents are continuously output, the image contents are continuously output by inserting an effect corresponding to attribute information possessed by each image content. Patent Documents 2 and 3 are also related to the present invention and provide image processing devices which apply effects on images. Patent Document 1: JP2008-61032APatent Document 2: US 2006/007501Patent Document 3: US 2008/084586 SUMMARY OF THE INVENTION Here, there is a change over time as one of changes that interest people. For example, in leather products, a surface of leather gradually changes according to the number of years of use, and each change gives a different aesthetic appearance. In addition, for example, the taste of sake gradually changes according to a storage period, and a person who drinks sake can enjoy the change of the taste. Patent Document 1 mentioned above discloses a technique in which a recording date and time of the content is compared with a reproduction date and time and a sepia effect is selected in a case where the value is equal to or greater than a threshold value (Patent Document 1: paragraph 0055), but this change is a one-time change and is not a change over time that gradually changes according to an elapsed time. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an image processing device, an image processing method, an imaging device, and a program capable of performing image processing that changes over time. An image processing device according to an aspect of the present invention for achieving the above object is given in claim 1 and comprises: an image acquisition unit that acquires a captured image to be processed from a storage unit in which a captured image having first date and time information indicating a time of imaging is stored, a date and time information acquisition unit that acquires the first date and time information from the captured image to be processed and acquires second date and time information indicating a date and time when the captured image to be processed is acquired from the storage unit by the image acquisition unit, an elapsed date and time calculation unit that calculates an elapsed date and time from the time of imaging by making a comparison between the first date and time information and the second date and time information acquired by the date and time information acquisition unit, and an image processing unit that selects image processing based on a length of the elapsed date and time from among a plurality of kinds of image processing that change according to the length of the elapsed date and time and performs the selected image processing on a subject or a region of a part of the captured image to be processed. According to the present aspect, the elapsed date and time from the time of imaging is calculated, and the image processing is performed based on the length of the calculated elapsed date and time from among the plurality of kinds of image processing that change according to the length of the elapsed date and time. Thus, in the present aspect, the image processing that changes over time can be performed on the captured image. Preferably, the image processing device further comprises a display control unit that causes a display unit to display the captured image to be processed on which the image processing is performed by the image processing unit. Preferably, the image processing device further comprises a printing control unit that causes a printing unit to print the captured image to be processed on which the image processing is performed by the image processing unit. Preferably, the captured image to be processed on which the image processing is performed by the image processing unit and the captured image to be processed before the image processing is performed by the image processing unit are stored in the storage unit. Preferably, the captured image to be processed on which the image processing is performed by the image processing unit is not stored in the storage unit. Preferably, the image processing device further comprises a relationship input unit that receives input of a correspondence on a time base between the plurality of kinds of image processing and the length of the elapsed date and time.
