Apparatus and method for correcting backlight of camera

A method for correcting the backlight of a camera having a shutter configured to operate in a backlight shooting mode, comprising:

• varying a speed of the shutter over a plurality of fields so that a long shutter speed operation and a short shutter speed operation are performed once respectively per field, the short shutter speed operation being performed at a starting portion of a corresponding field;
• increasing a digital gain of images shot with the long shutter speed;
• reducing a digital gain of images shot with a short shutter speed;
• synthesizing long and short shutter speed images into a final image;
• and
• outputting the final image.

A method for correcting the backlight of a camera having a shutter configured to operate in a backlight shooting mode, comprising:

• varying a speed of the shutter over a plurality of fields so that a long shutter speed operation and a short shutter speed operation are performed once respectively per field, the short shutter speed operation being performed at an end portion of a corresponding field;
• increasing a digital gain for images shot with the long shutter speed;
• decreasing a digital gain for images shot with the short shutter speed;
• synthesizing long and short shutter speed images into a final image;
• and
• outputting the final image.

A method for correcting the backlight of a camera having a shutter configured to operate in a backlight shooting mode, comprising:

• varying a speed of the shutter over a plurality of fields so that a long shutter speed operation is performed once and a short shutter speed operation is performed twice respectively per field;
• increasing a digital gain for images shot with the long shutter speed;
• decreasing a digital gain for images shot with the short shutter speed;
• synthesizing long and short shutter speed images into final images;
• and
• outputting the final images.

An apparatus for correcting the backlight of a camera, comprising:

• a shutter;
• a controller configured to vary a speed of the shutter between a long shutter speed and a short shutter speed;
• and
• a signal processor configured to synthesize an image shot with the long shutter speed with an image shot with the short shutter speed to produce a final image, and to output the final image.
