Matrix metering, английский
- In most digicams there is a matrix metering option which uses 256 areas of the frame to calculate the best overall exposure value. see also: spot metering and center-weighted
- Also known as segmented metering, matrix metering takes the total image area and breaks it into sections, which are analyzed by the camera`s light meter and compared to the light values of the surrounding sections. the results are then compared to similar lighting situations stored in the camera`s memory and a correct exposure is established. this entire process occurs in a few microseconds. for more on this subject, see the explora article, “understanding camera metering modes.”

Li-ion, английский
- Some digicams are packaged with a lithium rechargeable battery pack. lithium batteries are lighter but more costly than nimh or nicd type of rechargeable cells. lithium cells can be recharged regardless of their state of discharge, they`re lighter in weight and maintain a charge better in colder temperatures. also holds a charge longer when idle.
- (lithium ion). some digicams are packaged with a lithium-ion re-chargeable battery pack. lithium ion batteries are lighter but are more costly than ni-mh or ni-cd (nicad) rechargeables. one advantage is that lithium cells can be recharged regardless of the amount of discharge; also, they are lighter and maintain a charge much better in colder temperatures than conventional batteries. li-ion also holds a charge for longer when idle.
