2 - EYE AND CAMERA Flashcards
1
Q
eye is an optical device for projecting an image onto light sensitive elements in the retina
A
-
2
Q
light proof chamber?
A
CAMERA
- yes
- camera body
EYE
- yes
- eyeball
3
Q
hole for light to enter?
A
CAMERA
- yes
- aperture
EYE
- yes
- pupil
4
Q
automatic control of hole size?
A
CAMERA
- yes
- in auto mode
EYE
- yes
- pupillary light reflex
5
Q
lenses?
A
CAMERA
- yes
- two or more
EYE
- yes
- two
6
Q
automatic focus?
A
CAMERA
- yes
- autofocus
EYE
- yes
- accommodative reflex
7
Q
array of light sensitive elements that convert light stimulation into electrical signals?
A
CAMERA
- yes
- pixels in the pixel sensor
- 10 magapixels = 10 million elements
EYE
- yes
- photoreceptors in the retina
- rods and cones
8
Q
automatic image stabilisation?
A
CAMERA
- yes
- electronic image stabilisation
EYE
- yes
- vestibular ocular reflex
9
Q
differences
A
- living tissue / not
- eye = 2 types of photoreceptor
- camera = 1
- space in camera = air
- space in eye = fluid or jelly
10
Q
similar job
A
‘convert an image (a two dimensional pattern of light) into a pattern of electrical signals in a large number of elements’
then transmitted elsewhere
neither can actually see
