| 20100158495 | AUTOFOCUS ASSIST LIGHTING USED FOR RANGEFINDING IN VERY LOW LIGHT CONDITIONS - Autofocus (AF) assist lighting can be useful as a camera rangefinder in low light conditions. When ambient light conditions are inadequate for determining camera-to-subject distance using through-the-lens autofocus (TTL-AF) procedures, the AF assist light is used to attempt to raise the light level enough that the camera-to-subject distance can be determined using TTL-AF. If a camera-to-subject distance is not determined when the AF assist light is used, a camera-to-subject distance based on tabulated values is determined using an empirical model of AF assist luminance increment versus distance. If a camera-to-subject distance can be determined using TTL-AF when the AF assist light is used, but the lighting conditions are inadequate, the camera-to-subject distance used for capturing an image is a weighted combination of the TTL-AF camera-to-subject distance and a camera-to-subject distance based on a set of tabulated values determined using an empircal model of AP assist luminance increment versus distance. | 06-24-2010 |

| 20110243541 | Defocus calibration module for light-sensing system and method thereof - A defocus calibration module is applied in a light-sensing system utilized for sensing a measured object for generating a sensed image. The light-sensing system comprises a light-emitting component, a focusing component, and an image sensor. The light-emitting component emits a detecting light to the measured object so that the measured object generates a reflecting light. The focusing component focuses the reflecting light to the image sensor. The image sensor generates the sensed image according to the reflecting light. The defocus calibration module has a calibrating object for blocking a part of the detecting light and the reflecting light for forming images at a first and a second calibration imaging locations in the sensed image. In this way, the defocus calibration module calculates a defocus parameter representing the defocus level of the light-sensing system according to the first and the second calibration imaging locations, and accordingly calibrates the sensed image. | 10-06-2011 |

When operating the camera, the AF lighting device is activated to emit light after a shutter button of the camera is pressed halfway down, and a preview picture is displayed on a panel of the camera. A central position of the emitted light is then transposed toward a center of the panel according to the stored relative position. | 11-17-2011 |

In the event the brightness value is greater than the flash threshold, cause the flash to generate a shortened pre-flash and obtain only a white balance measurement and an auto-exposure measurement during the shortened pre-flash. | 06-21-2012 |
