USB CIF/VGA Digital Camera Chipset

STMicroelectronics 

STV0672-chipsetf-3-1.fm

Detailed specifications

source will be white light that has been IR filtered, producing a diffuse uniform illumination at the surface of the sensor package.

The FPN will be calculated at coarse exposure settings of 0,10,150,250 and 302 with gain set to 1. 10 frames are grabbed and

averaged to produce a temporally independent frame before each calculation. FPN will be expressed in mV.

4.4.5 Vertical Fixed Pattern Noise

VFPN describes the spatial noise in an image sensor related to patterns with a vertical orientation. The VFPN is defined as the

standard deviation over all columns of the average pixel voltage for each column determined at zero exposure and zero

illumination. VFPN will be expressed in mV.

4.4.6 Random Noise

Random noise is the temporal noise component within the image. Random noise will be expressed in mV.

4.4.7 Shading

This describes how average pixel values per “block” change across the image sensor array. For fine shading calculations the

image sensor array is split into 30 pixel by 30 pixel blocks. An average value is then calculated for each block and the averages

are then compared across the whole device. The blocks are increased in size to 60 pixels by 60 pixels for the gross shading

calculation. Shading will be expressed in mV.
