Global Shutter
When it’s about the best sensor flattering high-end industrial needs, then CMOSIS CMV12000 represents the right choice. These sensors entail extraordinary performance breakthroughs due to their core global shutter architecture designed to provide optimum imaging performance even during starved light conditions. The high performing sensors are very competitive and available in three compatible versions including colour, Near Infrared Enhanced Monochrome (NIR) and monochrome addition. This high sensitivity image sensor with amazing super HD resolution of 4096 x 3072 pixels delivers out of the world performance by displaying the promise of un- compromised imaging. The pipelined global shutter pixel architecture implies that exposure during readout is probable while ensuring reduction in temporal dark noise by implementing true correlated double sampling (CDS) technique. The image sensor also encloses 64 LVDs output channels to deliver 300 frames per second in full resolution while running at 300 Mbps. The serial peripheral interface is used to programme driving and read-out, while an internal timing generator produces all the required signals for performing exposure of the sensor and readout.
Architecture
The pixel array of the sensor first stores the image data which readouts the pixels row by row sequentially and then transmits this value to the next stage for ADC conversion. The imager sensor constitutes analog front end made up of two parts i.e. column amplifier block and ADC block. While using an SPI interface the column amplifier block applies analog gain for preparing the pixel signal for onward conversion into a pixel value by column ADC block in 8,10 or 12-bit values. The CMOSIS sensor encloses 66 LVDs pairs for performing varied functions i.e. 64 data channels transfer the image data to the receiver, 1 output clock channel transmits DDR clock in synchrony with other LVDs at maximum 300 MHz and 1 control channel validate the data by examining the status information displayed by the data channels. The prime function of these LVDs channels is to convert digital data received from ADC block into standard LVDs data for performing readout of all the digital signals.
SPI Interface
To speed up the process of read-out, the pixel signals are readout on both sides in parallel order to achieve up to 150 frames per second in a 10-bit mode. While the row-decoder completes the readout cycle, flexible windowing is allowed by selecting rows of interest in the Y direction. At this level, sensor programming is performed by already predicting and uploading control register parameters via SPI interface. While the inclusion of temperature sensors is also facilitated by SPI interface which performs its subsequent read-out. Hence, CMOSIS CMV12000 sensors with superior performance standards is ideal for providing different resolution measures to suit the needs of individual industrial applications by focusing on customizability.
