Casio Japan unveiled [JP] two new Exilim point-and-shoot cameras today, the EX-Z450 and the EX-Z90. The main selling point of the devices is the ability to detect objects (not only human beings) and to then automatically set the focus and exposure area to give you high-quality pictures.

The EX-Z90 can be considered weaker than the Z450. It features a 12.1MP sensor, a 2.7-inch LCD screen, 3x optical zoom, an ISO range of 64 to 1,600, an SDHC/SD memory card slot and 35.7MB of internal memory. The camera weighs 102g and will be available in gold, silver, pink, blue and black (release date in Japan: September 11, price: $210).

The EX-Z450 has a 12.1MP CCD sensor, a 3-inch LCD screen, a 28mm 4x optical zoom lens and features an ISO range of 64 to 3,200. It can record video in 720/24p (Motion JPEG) and also comes with an SDHC/SD memory card slot and 35.7MB of internal memory. The Z450 is slightly heavier at 130g and will cost $380 when it goes on sale in Japan on August 28 (in gold, red and pink; the models in brown and silver follow September 11).

Casio hasn’t said yet when or if the Exilim cameras will find their way outside Japan.
