Week 5 Lighting and Imagining
digital image
pixel contains an numerical value
pro
quantitative information
qualitative information for analysis
non-invasive
con
low resolution
too much data
less sensitive
large equipment
imaging
camera
magnification
aberration
chromatic aberration
due to dependence of refractive index on wavelength
aperture
DOF
sensor array
principle
photoelectric effect
specification
sensitivity
quantum efficiency
incident frequency
frame rate
noise
pixel size
native pixel size
effective pixel size
resolution
dynamic range
CCD
principle
ADC
read out one at a time
characteristic
efficient
expensive, slow but low noise
CMOS
characteristic
low efficiency
micro-lenses are increasinf efficiency
due to low fill factor
high noise
cheap
high frame rates
several transistor at each pixel, amplify and move the charge using simple track
choose
fix/moving
exposure time
frame rate
magnification
sensitivity
intensity
high/low light
