5. Pinhole Camera • Alhazen (Ibn Al-
Haytham)around
1000AD,
• Invented the first
pinhole camera,
(also called the
Camera Obscura}
• Able to explain
why the images
were upside
down
The first casual reference to the optic laws that made pinhole
cameras possible, was observed and noted by Aristotle around
330 BC, who questioned why the sun could make a circular image
when it shined through a square hole6/21/2013 5© Niyam Raj Shrestha

16. What are the parts and function in
digital camera?
• The lens
• The CCD or CMOS sensor
The light that enters the lens and translates it into a digital signal.
The size of the CCD or CMOS varies, from 25mm2 up to 1977mm2 and
can contain anywhere from less than 1 million pixels (1MP) to 24
million pixels (24MP) and up. Each pixel is a 'dot' in the image, the
more megapixels the more dots that comprise the image. This is not a
measure of quality, it is only a measure of size.
• The PCB
There can be one or more Printed Circuit Boards inside the camera.
These process the information and are the 'brains' of the camera.
Think of it like the motherboard inside your computer, just much
smaller.
• The memory
• The LCD screen
• The flash
• The body6/21/2013 16© Niyam Raj Shrestha
