Abstract

A camera operating apparatus and method are provided. The apparatus includes a signal processor for rotating and storing a shot image so that a storage direction of the image shot with the camera rotated 90° or 180° may be a reference storage direction. The shot image is stored in such a way that a storage direction of the image shot with the camera rotated may be the reference storage direction, which provides convenience that a user needs not to rotate the camera to check the shot image when playing the image.

Claims

1. An image rotating apparatus that receives a captured image from an optical system for storage in a memory, the apparatus comprising:

a symbol generator that provides a reference symbol on a display panel, the reference symbol being movable according to a user input;

a judgment unit in communication with the symbol generator, wherein the judgment unit determines a rotation angle and a rotation direction of the optical system based on the user input;

a position setting unit in communication with the symbol generator for storing a location of the reference symbol; and

an image processor in communication with the judgment unit, wherein the image processor changes data of the captured image according to the rotation angle and the rotation direction to rotate the captured image, and stores the data to the memory,

wherein the position setting unit is in further communication with the judgment unit for outputting the location, the judgment unit comparing the location with a default reference location.

2. The image rotating apparatus of claim 1 wherein the default reference location is a bottom of the display panel.

3. The image rotating apparatus of claim 1 wherein the user input comprises a position setting actuator.

4. The image rotating apparatus of claim 3 wherein the position setting actuator is selected from the group consisting of a right-movement button, a left-movement button, an upward-movement button and a downward-movement button.

5. The image rotating apparatus of claim 3 wherein the position setting actuator comprises a position setting button that generates one or more user input signals for moving the reference symbol based on a number of times that the position setting button is pressed.

6. A digital camera that saves a plurality of captured images in a like orientation regardless of a camera orientation, the digital camera comprising:

a display that reproduces an image to be captured;

a user input including a reference location means and a shutter button;

a memory that stores the plurality of images; and

a processor linked with the display, the user input and the memory, the processor comprising;

a symbol generating means for displaying a reference symbol on the display, the reference symbol being movable on the display according to a signal from the reference location means;

a judgment means in communication with the symbol generating means for determining the camera orientation relative to a location of the reference symbol; and

an image processing means in communication with the judgment means for changing a data of a captured image according to the location of the reference symbol to rotate the captured image and storing the data to the memory.

7. The digital camera of claim 6 wherein the processor further comprises a position setting means in communication with the symbol generating means for storing the location of the reference symbol.

8. The digital camera of claim 7 wherein the position setting means is in farther communication with the judgment means for outputting the location, the judgment means comparing the location with a default reference location.

9. The digital camera of claim 8 wherein the default reference location is a bottom of the display.

10. The digital camera of claim 6 wherein the processor comprises at least one of a digital signal processor and a microcontroller.

11. The digital camera of claim 6 wherein the reference location means comprises a position setting actuator.

12. The digital camera of claim 11 wherein the position setting actuator is selected from the group consisting of a right-movement button, a left-movement button, an upward-movement button and a downward-movement button.

13. The digital camera of claim 11 wherein the position setting actuator comprises a position setting button that generates one or more user input signals for moving the reference symbol based on a number of times that the position setting button is pressed.

14. A method for rotating an image in a digital camera, the method comprising:

displaying a reference symbol on a display of the digital camera;

selecting a position on the display for the reference symbol relative to a user input, the selecting step comprising;

detecting a first signal from a shutter actuator;

detecting, substantially simultaneously with the first signal, a second signal from a position setting actuator;

moving the position of the reference symbol on the display; and

setting the position;

capturing an image reproduced on the display with the reference symbol;

judging a rotation state of the image relative to the position of the reference symbol;

changing an image data to rotate the image; and

saving the image data resulting from the changing step.

15. The image rotating method of claim 14 wherein the setting step comprises:

detecting a third signal from a confirmation actuator; and

storing the position of the reference symbol to a memory.

16. The image rotating method of claim 15 wherein the judging step comprises:

determining a default position for the reference symbol;

recalling the position from the memory; and

comparing the position with the default position to determine a rotation angle and rotation direction.

17. The image rotating method of claim 16 wherein the changing step comprises rearranging the image data to counteract the rotation angle and rotation direction.
