Hardware Components Flashcards
Bayer Pattern
mosaic arrangement of a color filter array; RGB color filters on a square grid of photosensors
distribution of bayern pattern
50% green, 25 red, 25 blue
SAR
Successive Approximation Register, ADC that is useful for applications requiring a sample rate under 10MSPS
S/H
Sample and Hold circuit that samples the voltage of an analog signal and holds its value at a constant level for a specified minimum period time
TRDB-D5M
5 Mega Pixel Digital Camera
Pixel Array of TRDB-D5M
active region, boundary region that’s also active, and border of dark pixels
boundary region of TRDB-D5M’s pixel array
used to avoid edge effects from color processing
PIXCLK
can be used as a clock to latch the data so every cycle, a 12-bit pixel value outputs on the DOUT pins
FVAL and LVAL high
pixel valid
FVAL negated
vertical blanking
LVAL negated
horizontal blanking
subsampling
reduce output resolution without reducing field of view
Row and column binning modes
can reduce the impact of aliasing from skip modes
skipping
skips one bayer pair of pixels for every pair output, can be 2x or 3x and column and/or row; method for reducing output resolution
binning
combines adjacent same-color imager pixels to make one output pixel; another method for reducing output resolution
