ISO is a rough measure of sensitivity to low light.

ISO大致是在暗光下对光的敏感程度。

You will often find yourself alternating between low light and daylight, so make sure you reset the ISO to the lowest setting immediately after you have finished shooting at a higher sensitivity.

你常常会在微弱光线和日光下变换拍摄，所以当你用高iso值拍摄完毕后，一定不要忘记马上把它调回最低值。

They are characterized by ruggedness, light weight, high sensitivity, low acoustic impedance, easy conformability to complex surface, low cost and large bandwidth.

它具有耐磨、量轻、灵敏度高、声学阻抗低、容易固定在复杂的表面、价格便宜，频带宽等特点。

Leveraging its innovation and technology expertise, Toshiba developed its newest CMOS image sensor with BSI and CNR integrated on the sensor to address both low-light sensitivity and SNR.

The new imager utilizes Samsung's advanced 1.4 micron (um) back side illuminated (BSI) pixel technology to offer superior low-light sensitivity, satisfying the high quality imaging requirements of smartphones, high-end feature phones and camcorders.

Taking cues from its Alpha A99, which was just announced today, Sony brought that camera's 24.3-megapixel full-frame sensor to a camcorder form factor, delivering shallow depth-of-field and much improved low-light sensitivity in a more practical package.
