a control unit configured to simultaneously display first image data corresponding to light field data included in the first image file and second image data corresponding to image data included in the second file on a display, and
wherein the control unit determines whether the image to be displayed corresponds to light field data or not by analyzing each data in a plurality of image files acquired by the acquisition unit, and performs display for informing a user that the displayed image data corresponds to either the first image data or the second image data.
2. The image processing apparatus according to claim 1 , wherein
the light field data that includes the information corresponding to a light field includes a plurality of pieces of image data having different disparities.
3. The image processing apparatus according to claim 1 , further comprising:
a generation unit configured to generate a plurality of images having different focus positions from the light field data,
wherein the control unit informs a user that the image file is the first image file by alternately displaying on the display the plurality of images having the different focus positions.
4. The image processing apparatus according to claim 3 , wherein
the control unit alternately displays images in which focus is respectively placed on a nearest subject and a farthest subject that can be focused on the light field data.
5. The image processing apparatus according to claim 1 , further comprising:
a generation unit configured to generate a plurality of images having different view points from the light field data,
wherein the control unit informs a user that the image file is the first image file by alternately displaying the plurality of image having the different view points.
6. The image processing apparatus according to claim 1 , wherein
the first image file includes a plurality of pieces of image data having different disparities and composite image data obtained by compositing the plurality of pieces of image data having the different disparities.
7. The image processing apparatus according to claim 1 , wherein
the first image file includes a piece of image data of a plurality of pieces of image data having different disparities and composite image data obtained by compositing the plurality of pieces of image data having the different disparities.
8. The image processing apparatus according to claim 1 , further comprising:
a storage unit configured to store the first image files as an image file that can be inversely transformed.
9. The image processing apparatus according to claim 1 , wherein
the acquisition unit includes an image capturing element in which unit pixels that each include a plurality of photoelectric converting elements with respect to one microlens are arranged in a matrix.
10. The image processing apparatus according to claim 1 , wherein
the control unit displays an image corresponding to the second image data and the first image data different display modes.
11. The image processing apparatus according to claim 1 , wherein
the control unit superimposes display information indicating the first image data on the first image data on the display and does not superimpose the display information on the second image data.
12. The image processing apparatus according to claim 1 , wherein
the control unit superimposes display information indicating the first image data on the first image data on the display in a case where a plurality of image data corresponding to a plurality of image files stored in a memory are simultaneously displayed, and does not superimpose the display information on the first image data but displays the display information apart from the first image data on the display in a case where one of the plurality of the image data is displayed.
13. The image processing apparatus according to claim 1 , wherein the control unit determines whether the image to be displayed corresponds to light field data or not by analyzing a structure of a DCF image file of a plurality of image files acquired by the acquisition unit.
14. The image processing apparatus according to claim 1 , wherein the control unit determines whether the image to be displayed corresponds to light field data or not by determining whether predetermined image data is recorded.
15. The image processing apparatus according to claim 1 , wherein the first image file includes a plurality of RAW image data.
16. The image processing apparatus according to claim 1 , wherein the control unit analyzes an extension and determines whether the image file is moving image data or still image data.
17. An image processing method comprising:
acquiring a first image file that includes light field data and a second image file not includes light field data;
simultaneously displaying first image data corresponding to light field data included in the first image file and second image data corresponding to image data included in the second image file on a display, and
wherein in displaying, whether the image to be displayed corresponds to light field data or not is determined by analyzing each data in a plurality of image files acquired by the acquisition unit, and display for informing a user that the displayed image data corresponds to either the first image data or the second image data is performed.
18. A non-transitory computer readable storage medium storing a program for causing a computer to execute steps of an image display method,
the image processing method comprising:
acquiring a first image file that includes light field data and a second image file not includes light field data;
simultaneously displaying first image data corresponding to light field data included in the first image file and second image data corresponding to image data included in the second image file on a display, and
wherein in displaying, whether the image to be displayed corresponds to light field data or not is determined by analyzing each data in a plurality of image files acquired by the acquisition unit, and display for informing a user that the displayed image data corresponds to either the first image data or the second image data is performed.
