Digital camera CCD (charge-coupled device) and CMOS (complimentary metal-oxide semiconductor) image sensors convert light into electrons. The next step is to read the value (accumulated charge) of each cell in the image. In a CCD device, the charge is actually transported across the chip and read at one corner of the array. An analog-to-digital converter turns each pixel's value into a digital value.

Epistemology (knowledge) The science and philosophy of knowledge  from Greek ἐ πιστήμη – “episteme-” = knowledge, science  λόγος, “logos” = a subject, topic of discourse, area of study

Major concepts in Epistemology Constructivism o Building blocks Assimilation o Slot in beside Accomodation o Move stuff over Associationism o Connect things together

Next lecture... Mind Maps

Purpose of Lecture... To explain and illustrate that imagery (visualisation) makes it much easier for the human brain to absorb and remember information. o “Iconic learning” Lay groundwork for us to try out some of these techniques in our study and learning Also, to touch on some key concepts we will be returning to in future lectures for your work
