Fixed lens Although the term “digicam” originated as a
syllabic abbreviation for “digital camera”, it is now used primarily to refer to an old compact digital camera or, in other words, a discontinued
point-and-shoot camera with a fixed lens. Digicams emphasize portability and ease of use, and they often include a built-in
flash.
1/1.7″ CCD sensor or larger CMOS sensors have entirely replaced
CCD sensors in recent consumer digital cameras due to cost effectiveness and high ISO performance. However, in good lighting conditions, many people find that the CCD sensors in digicams yield a more pleasing color rendition than CMOS sensors. While there were larger CCD sensors made for interchangeable-lens cameras, such as the
Leica M9, CCD sensors in fixed-lens cameras maxed out at 2/3″ (1/1.5″). Premium compact cameras of the time contained sensors around 1/1.7″ in size, whereas entry-level models used 1/2.3″ sensors or smaller.
SDHC and SDXC cards Early digital cameras used a variety of formats for storage. Eventually
SD cards won the format war, and they are still widely used and readily available. However, the original SD format maxes out at 2GB and is now rare. Cards today far exceed that by using one of two format extensions:
SDHC, which maxes out at 32 GB, or
SDXC, which maxes out at 2 TB. SDXC support is more future-proof, but SDHC cards are still common and inexpensive. Support for the newer formats is important, because memory card slots are not usually
forward compatible.
Raw image format While the appeal of digicams stems from the ability of obtain pleasing results with a nostalgic look
straight out of camera, capturing in a
raw format maximizes the ability to
edit an image to one's taste or recover details (such as
highlights and shadows) that might otherwise be lost in the
JPEG version, especially given the low
dynamic range of these small-sensor cameras.
AA or AAA batteries New consumer digital cameras with CCD sensors stopped being released in the early 2010s, and the few that offered
USB charging only supported it via a non-standard cable.
Proprietary cables, chargers, and batteries can be difficult to come by, especially when discontinued, which makes support for standard
AA or
AAA batteries (especially
rechargeable NiMH cells) a desirable feature. == Larger CCD sensors ==
