an image processor to adjust a brightness of the image displayed on the display based on the detected exposure speed to provide a same light quantity at each exposure position among a plurality of exposure positions of the movable exposure member to the instant film, to thereby compensate for a deviation in the exposure speed of the movable exposure member.

2. The display apparatus as claimed in claim 1 , wherein

the touch sensor corresponds to an exposure position of the movable exposure member, and

the detector is to detect the exposure speed of the movable exposure member based on the position of the touch sensor on the touch screen.

3. The display apparatus as claimed in claim 2 , wherein the image processor is to adjust the brightness of the image in real time based on the exposure speed detected in real time.

4. The display apparatus as claimed in claim 1 , further comprising:

an imager to photograph an exposure position of the movable exposure member,

wherein the detector is further to detect the exposure speed of the movable exposure member based on the photographed exposure position of the movable exposure member.

5. The display apparatus as claimed in claim 1 , further comprising:

a storage to store the detected exposure speed,

wherein the image processor is to adjust the brightness of the image based on the stored exposure speed.

6. The display apparatus as claimed in claim 1 , wherein the exposure member is manually driven.

7. The display apparatus as claimed in claim 1 , wherein

the image processor is to divide the image into a plurality of areas corresponding to an exposure direction of the movable exposure member, and

the image processor is to adjust the brightness of each of the plurality of areas to provide the same light quantity at each exposure position among the plurality of exposure positions of the of the movable exposure member to the instant film.

8. The display apparatus as claimed in claim 1 , wherein the image processor is to adjust the brightness of the image to have a brightness value corresponding to the detected exposure speed in a direction of the image corresponding to an exposure direction of the movable exposure member.

9. The display apparatus as claimed in claim 1 , wherein

the detector is to detect the exposure speed of the movable exposure member for a plurality of exposure sections, respectively, and

the image processor is to adjust the brightness for a plurality of image areas of the image based on the detected exposure speeds, for the plurality of exposure sections which respectively correspond to the plurality of image areas.

10. The display apparatus as claimed in claim 1 , further comprising:

a controller to adjust a brightness of the display to be at least a predetermined brightness and to control the image processor to adjust the brightness of the image based on the adjusted brightness of the display, upon receiving a printing command.

11. The display apparatus as claimed in claim 1 , further comprising:

a controller to control the display to display the image at a refresh rate different from a predetermined refresh rate upon receiving a printing command.

12. The display apparatus as claimed in claim 11 , wherein the controller is to control the display to display the image at the predetermined refresh rate.

13. The display apparatus as claimed in claim 11 , wherein the controller is to control the display to display the image at a refresh rate corresponding to the detected exposure speed of the movable exposure member.

14. The display apparatus as claimed in claim 1 , wherein

the image processor is to divide the image into a plurality of areas, including a first area, a second area, and a third area, and

when the exposure speed of the movable exposure member is higher with respect to the first area compared to the second and third areas, and the exposure speed of the movable exposure member is higher with respect to the second area compared to the third area and less compared to the first area, the image processor is to adjust a brightness value of the first area to be higher than a brightness value of the second and third areas, and to adjust a brightness value of the third area to be lower than a brightness value of the first and second areas.

15. A display control method of a display apparatus, the method comprising:

displaying an image on a touch screen of the display apparatus;

sensing, on the touch screen, a touch of a touch sensor of a portable imaqe-forming apparatus while the touch sensor moves along the touch screen;

detecting based on the sensing of the touch of the touch sensor, by at least one processor of the display apparatus, an exposure speed of a movable exposure member of the a portable image-forming apparatus that exposes an instant film to light using light emitted from the image displayed on the display;

adjusting, by the at least one processor of the display apparatus, a brightness of the image displayed on the display based on the detected exposure speed to provide a same light quantity at each exposure position among a plurality of exposure positions of the movable exposure member to the instant film, to thereby compensate for a deviation in the exposure speed of the movable exposure member; and

displaying, on the display of the display apparatus, the image of which the brightness is adjusted.

16. A display apparatus, comprising:

a display to display an image;

an imager to photograph exposure positions of a movable exposure member of a portable image-forming apparatus that exposes an instant film to light using light emitted from the image displayed on the display,

a detector to detect an exposure speed of the movable exposure member based on the exposure positions of the movable exposure member photographed by the image; and

an image processor to adjust a brightness of the image displayed on the display based on the detected exposure speed so that a same light quantity at each exposure position of the movable exposure member is provided to the instant film to thereby compensate for a deviation in the exposure speed of the movable exposure member.
