20080218615 | Apparatus and method for stabilizing image sensor black level - 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. | 09-11-2008 |
20090015301 | CONTROLLING TIMING DEPENDENCIES IN A MIXED SIGNAL SYSTEM-ON-A-CHIP (SOC) - The claimed subject matter provides systems and/or methods that facilitate controlling timing dependencies in a mixed signal circuit. Timing performance associated with a horizontal scanner and an analog to digital converter (ADC) can be monitored. Moreover, data related to the monitored timing performance can be leveraged to modify timing parameter(s) of clocks that coordinate operations of the horizontal scanner and the ADC (e.g., and/or digital component(s) included in the mixed signal circuit). For example, the clocks associated with the horizontal scanner and the ADC can be independently tuned to optimize mixed signal circuit performance. | 01-15-2009 |
20090278951 | Apparatus and methods for multi-sensor synchronization - Apparatus and methods for synchronizing a plurality of image sensors in a video camera system. In one embodiment, a method includes generating a video sync signal, and resetting at least one internal clock divider in each image sensor in synchronization with the video sync signal at the beginning of each video frame. Another embodiment of a method of synchronizing a plurality of image sensors in a video camera system includes detecting a phase state of a signal of at least one internal clock divider in each sensor, wherein the phase state is relative to a system sync signal, and selecting a video output signal for each sensor based on the detected phase state of the at least one internal divider. In a third embodiment, the method includes asserting an asynchronous reset signal, stopping the system clocks in the system, de-asserting the asynchronous reset signal, while the system clocks are stopped, and restarting the system clocks. Each method may be used individually, or the methods can be combined in any combination. A video camera apparatus is also described. | 11-12-2009 |
20110063483 | Image sensor with wide dynamic range - An image sensor, system and method that alternates sub-sets of pixels with long exposure times and pixels with short exposure times on the same sensor to provide a sensor having improved Wide Dynamic Range (WDR). The sub-sets of pixels are reset at different time intervals after being read, which causes the respective integration times to vary. By combining information contained in the both the short and long integration pixels, the dynamic range of the sensor is improved. | 03-17-2011 |
