Samsung TL500 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor . On the other hand, Casio EX-100 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor .
Below you can see the TL500 and EX-100 sensor size comparison.
Samsung TL500 and Casio EX-100 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Samsung TL500 has 20% larger pixel area compared to Casio EX-100, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
