Taiwan National Chiao Tung University published a nice CMOS image sensor course materials covering pretty much all important things in just 75 slides, written by Chia-Ming Tsai. There is also 58-slide long CCD course on the same page.
Update: As written in comments, most of the material in the CMOS and CCD slides is not original and, actually, copied from Albert Theuwissen's and Stanford University courses.
