摘要： An apparatus and method for fixed pattern noise (FPN) correction in an image sensor utilizes at least one row of test pixels. An external voltage is applied to each pixel circuit in the at least one row. Thus, the output of the test pixels does not depend on the photo or dark current signals. The applied voltage is used to determine a column offset error for each column in the image sensor.

摘要： A black clamp stabilization circuit for an image sensor utilizes a mixed-signal SoC block comprising sub-blocks to dynamically and precisely adjust the black level based on comparison to a reference black level. The black level adjustments include a first level regulation using digital control of an analog signal in a feedback loop that includes a programmable gain amplifier and high-resolution A/D converter. By applying the black clamping in the analog domain, dynamic range is extended. Additional black level regulation is subsequently performed in the digital domain to differentially eliminate line noise and column noise generated within the imaging System-on-Chip. By providing information between the sub-blocks, the algorithms can converge more quickly. The technique enables multiple signal paths to separately handle individual colors and to increase imaging data throughput.
摘要翻译：用于图像传感器的黑色钳位稳定电路利用包括子块的混合信号SoC块，以基于与参考黑色电平的比较来动态且精确地调整黑色电平。黑电平调节包括使用包括可编程增益放大器和高分辨率A / D转换器的反馈环路中的模拟信号的数字控制的第一电平调节。通过在模拟域中施加黑色钳位，可以延长动态范围。随后在数字域中执行额外的黑电平调节，以差分消除在成像片上系统中产生的线噪声和列噪声。通过在子块之间提供信息，算法可以更快地收敛。该技术使得多个信号路径可以分开处理各种颜色并增加成像数据吞吐量。

摘要： A black clamp circuit for an image sensor utilizes a differential programmable gain amplifier and a feed-back loop to adjust a black level based on comparison to a reference black level. The gain (and therefore step size and range) of the feed-back loop constant for all programmable gain amplifier gain settings. The gain of the fee- back loop is kept constant by adjusting the values of programmable capacitors in the circuit.

摘要： 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.

摘要： 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 pushsize 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.
摘要翻译：用于校正图像传感器中的列固定模式噪声（FPN）的方法提供用于计算列FPN偏移的速度和精度之间的折衷。本校正技术是数字的，并且在像素信号电压被ADC数字化之后被应用。对第一个光学黑（OB）像素进行采样并与目标电平进行比较。存储偏移量，并确定适当的推送尺寸。对其他OB像素进行采样，并应用偏移。根据所施加的偏移的像素信号是否高于或低于目标值，推送尺寸被增加或减小。这个新的偏移值被写入存储器，并且推式尺寸减小，并且重复该过程，直到最后一个OB像素被处理。所产生的偏移量应用于列中的信号像素。

摘要： An apparatus and method for forming optical black pixels having uniformly low dark current. Optical Black opacity is increased without having to increase Ti/TiN layer thickness. A hybrid approach is utilized combining a Ti/TiN OB layer in conjunction with in-pixel metal stubs that further occlude the focal radius of each pixel's incoming light beam. Additional metal layers can be used to increase the opacity into the infrared region.

摘要： An aircraft comprises a turbine engine (104) suspended from a wing (102) by means of a pylon (105). Compressed hot air is bled off from the turbine engine (104). A bleed air duct (209) in the wing (102) conveys the compressed hot air towards a fuselage. In order to prevent overheating of aircraft parts that are relatively close to the bleed air duct (209), the following solution is proposed. The pylon (105) comprises an opening (302) with a covering structure (303) projecting into a bypass exhaust flow (213) from the turbine engine (104). The covering structure (303) leaves a slit (304) facing away from the bypass exhaust flow (213). An airflow path (305) extends from openings (211) in the wing (102) to the slit (304) left by the covering structure (303).
