20090278962 | Method for fixed pattern noise (FPN) correction - A method for correcting column Fixed Pattern Noise (FPN) in an image sensor offers a compromise between speed and precision for calculating column FPN offsets. The present correction technique is digital, and is applied after the pixel signal voltages have been digitized by an ADC. A first Optical Black (OB) pixel is sampled and compared to a target level. An offset is stored, and an appropriate push-size is determined. Additional OB pixels are sampled and the offset is applied. The push-size is increased or decreased depending upon whether the pixel signal with the applied offset is above or below a target value. This new offset value is written to memory, and the push-size is reduced, and the process is repeated until the last OB pixel has been processed. The resulting offset is applied to the signal pixels in a column. The primary advantage of this approach is that within a single frame, a good estimate of the column offset is made which is not as affected by outlier pixels (such as “hot” or “flashing” pixels). | 11-12-2009 |
20090278963 | Apparatus and method for column fixed pattern noise (FPN) correction - An apparatus and method for fixed pattern noise (FPN) correction in an image sensor utilizes at least one row of test pixels.

The applied voltage is used to determine a column offset error for each column in the image sensor. | 11-12-2009 |
20090279809 | Apparatus and method for gain correction - An apparatus and method for digital column gain mismatch correction are described. At least one test signal pixel is added to each column in an image sensor. For each column the test signal from at least one test pixel is read and compared to a target value. A correction value is calculated based on comparing the test signal to the target value. The correction value is stored in a memory. When the regular photo-pixels are read, the photo-pixel signals are modified based on the stored correction value for each column. | 11-12-2009 |

20140288365 | SCOPE SENSING IN A LIGHT CONTROLLED ENVIRONMENT - The disclosure extends to methods, systems, and computer program products for detecting whether an illumination source of an endoscope is in use (inside the body of a patient) versus not in use (outside the body of a patient). The disclosure relies on the fact that the working environment is lit solely by the endoscope and its components. Thus, communication between the illumination or light source controller and the imaging device, such as a surgical camera, is required. When the illumination or light source is turned off and the endoscope is outside the body, a sensor will detect ambient light alerting the illumination source controller that it is outside the body, which then keeps the illumination source off or at a low intensity level. Conversely, when the illumination source is turned off and the endoscope is inside the body, the sensor will not detect any light (or will detect only a very low level of light). Based on this logic, if the imaging device, such as a camera, knows that the light is off during a specific period of time the frame(s) from that time period can be analyzed and the level of light gathered in the frame(s) will show the scope location either inside or outside of the body. | 09-25-2014 |
