Method and apparatus for selectively supporting raw format in digital image processor
A digital image processing apparatus and method for supporting a RAW format (a sensor data format before image processing is performed) selectively supports a user-desired region of a captured image in a RAW format. A method of supporting a RAW format in a digital image processing apparatus includes setting at least one portion of an image displayed in a live-view mode as a region of interest (ROI), storing the ROI in a RAW format, storing a non-ROI of the displayed image, which is a portion of the image other than the ROI, in a compression format, and compositing the stored ROI with the stored non-ROI.
1. A method of supporting a RAW format (a sensor data format before image processing is performed) in a digital image processor, the method comprising:
setting at least one portion of an image displayed in a live-view mode as a region of interest (ROI);
storing the ROI in a RAW format;
storing a non-ROI of the displayed image, which is a portion of the image other than the ROI, in a compression format; and
compositing the stored ROI with the stored non-ROI;
wherein the ROI is automatically set according to a condition that is predetermined based on a scene mode, and
wherein, if the scene mode is a portrait mode, the ROI is automatically set according to a ratio of a face region recognized on the displayed image.
2. The method of claim 1 , wherein the ROI comprises at least one region of the displayed image.
3. The method of claim 1 , wherein the ROI is manually set by a user.
4. The method of claim 1 , further comprising performing image processing on the ROI before the compositing of the ROI.
5. The method of claim 1 , further comprising storing the ROI in a compression format.
6. The method of claim 1 , wherein the compositing of the ROI is performed by using an α blending method.
7. The method of claim 1 , wherein the ROI is set by using an object tracking method.
8. A digital image processing apparatus for supporting a RAW format (a sensor data format before image processing is performed), the processing apparatus comprising:
an ROI setup unit that sets at least one portion of an image displayed in a live-view mode as a region of interest (ROI);
a RAW storage that stores the ROI in a RAW format;
a compression storage that stores a non-ROI of the displayed image, which is a portion of the image other than the ROI, in a compression format; and
a composition unit that composits the stored ROI with the stored non-ROI;
wherein the ROI setup unit automatically sets the ROI according to a condition that is predetermined based on a scene mode, and
wherein, if the scene mode is a portrait mode, the ROI is automatically set according to a ratio of a face region recognized on the displayed image.
9. The digital image processing apparatus of claim 8 , wherein the ROI comprises at least one region of the displayed image.
10. The digital image processing apparatus of claim 8 , wherein the ROI is manually set by a user.
11. The digital image processing apparatus of claim 8 , wherein image processing is performed on the ROI before the composition unit composits the stored ROI with the stored non-ROI.
12. The digital image processing apparatus of claim 8 , wherein the compression storage further stores the ROI in a compression format.
13. The digital image processing apparatus of claim 8 , wherein the composition unit composits the ROI using an α blending method.
14. The digital image processing apparatus of claim 8 , wherein the ROI setup unit sets the ROI using an object tracking method.
15. The method of claim 1 , wherein, if the scene mode is a mode other than the portrait mode, the ROI is automatically set otherwise than if the scene mode is the portrait mode.
16. The digital image processing apparatus of claim 8 , wherein, if the scene mode is a mode other than the portrait mode, the ROI setup unit automatically sets the ROI otherwise than if the scene mode is the portrait mode.
