Device and method for adjusting inverted image in display system

A method for displaying an image in a portable telephone comprising the steps of:

• capturing an image with a camera;
• transmitting a command, which informs a display unit of a starting address of the image data, which is outputted;
• transmitting the image data captured by the camera;
• outputting the image data to the display unit from the starting address;
• judging whether the image data outputted to the display unit is displayed as an inverted image;
• operating a side key when the image data outputted to the display unit is displayed as an inverted image;
• transmitting a command, which informs the display unit of a revised starting address of the image data which is outputted;
• transmitting a command such that the image data is outputted in an inverted sequence;
• transmitting the image data captured by the camera;
• and
• outputting the image data from the revised starting address in the inverted sequence.

A method for displaying an image in a portable telephone comprising the steps of:

• capturing an image with a camera;
• designating a starting address of the image data outputted to a display unit;
• initializing a column counter value and a line counter value;
• transmitting the image data captured by camera to the display by increasing the column counter value until the column counter becomes a maximum value, and increasing the line counter value by one and re-initializing the column counter when the column counter value becomes a maximum value, wherein this procedure is repeated until both of the column counter value and the line counter value become maximum values;
• initializing the column counter value and the line counter value and terminating the outputting of the image data and displaying the image data in the display unit when both of them become maximum values;
• judging whether the image data outputted to the display unit is displayed as an inverted image;
• operating a side key when the image data outputted to the display unit is displayed as an inverted image;
• changing and designating the starting address of the image data outputted to the display unit;
• initializing the column counter value to a minimum value and the line counter value to a maximum value;
• transmitting the image data captured by the camera to the display by increasing the column counter value until the column counter becomes a maximum value, and decreasing the line counter value by one and re-initializing the column counter when the column counter value becomes the maximum value, wherein this procedure is repeated until the column counter value becomes the maximum value and the line counter value becomes the minimum value;
• and
• initializing the column counter value and the line counter value, terminating the outputting of the image data and displaying image data on the display unit when the column counter value becomes the maximum value and the line counter value becomes the minimum value.
