    Abstract: The present disclosure relates to methods and systems that may reduce pixel noise due to defective sensor elements in optical imaging systems. Namely, a camera may capture a burst of images with an image sensor while adjusting a focus distance setting of an optical element. For example, the image burst may be captured during an autofocus process. The plurality of images may be averaged or otherwise merged to provide a single, aggregate image frame. Such an aggregate image frame may appear blurry. In such a scenario, “hot” pixels, “dead” pixels, or otherwise defective pixels may be more easily recognized and/or corrected. As an example, a defective pixel may be removed from a target image or otherwise corrected by replacing a value of the defective pixel with an average value of neighboring pixels.

An input and output unit outputs the upper and lower limit voltages as the upper and lower limit values of a settable range of the S_signal validity determination voltage.

  • Patent number: 8858100
    Abstract: A camera module includes a lens system, an image sensor, and an actuator. The actuator is fixed relative to the image sensor, and the actuator moves the lens system relative to the image sensor to achieve focus. Components that move relative to each other result in gaps or spaces between the components, an in particular there is a gap between the lens system and the actuator. Such a gap provides a traveling path for foreign material, or particulates, to enter the camera module and reach the image sensor, or other intermediate optical components between the lens system and the image sensor. A camera contamination reduction apparatus is implemented as a protective membrane that prevents foreign material from reaching the internal optical components through the traveling path.

  • Patent number: 8744255
    Abstract: An auto-focus (AF) method adapted for an image capturing device includes following steps. When a first press signal generated by a user pressing a button of the image capturing device is detected, a local peak searching method is applied to perform an AF procedure. It is determined whether a second press signal generated by the user pressing the button is detected. If not, it is determined whether a first released signal generated by the user releasing the button is detected. The continuous pressing count is calculated according to the first released signal and the first press signal that are continuously generated. Whether the continuous pressing count is greater than a first threshold is determined. If yes, a global peak searching method is applied to perform the AF procedure. If not, the local peak searching method is still applied to perform the AF procedure.
