How does the EVOLT E-330 combat noise commonly found at high ISOs?

Digital cameras vary the light sensitivity of the image sensor by varying the gain voltage applied to the sensor, much like turning up the volume on a stereo. When the gain voltage is increased, as it is when shooting with higher ISOs, the sensor becomes hot. Hot pixels perform differently under extreme conditions. The result is a graininess known as “noise.” Noise occurs whenever sufficient heat has built up on the image sensor. Therefore, it can also be seen in images with long exposures, such as night photographs, due to the additional heat generated by charging the sensor for an extended period of time. All digital cameras include technologies to minimize the effects of noise. The EVOLT E-330 combats noise using two methods: NOISE FILTER and NOISE REDUCTION. The NOISE FILTER is an option in the ISO BOOST option in the (Custom 1) menu. The noise filter function is enabled in the ON+NF option to reduce noise at high ISOs. When the ON option is selected, the noise filter is not employ
