Sensors Equipping Compact Digital Cameras, Mega-zoom (bridge) Cameras and Camera-phones
Most image sensors equipping compact cameras have an aspect ratio of 4:3. This matches the aspect ratio of the popular SVGA, XGA, and SXGA display resolutions at the time of the first digital cameras, allowing images to be displayed on usual monitors without cropping.
As of December 2010 most compact digital cameras used small 1/2.3" sensors(or even smaller: 1/2.33"). Such cameras include Canon Powershot SX230 IS, Fuji Finepix Z90 and Nikon Coolpix S9100. Some older digital cameras (mostly from 2005–2010) used a tiny 1/2.5" sensor: these include Panasonic Lumix DMC-FS62, Canon Powershot SX120 IS, Sony CyberShot DSC-S700, and Casio Exilim EX-Z80.
High-end compact cameras using sensors of nearly twice the area than sensors equipping common compacts include Canon PowerShot G12 (1/1.7") and Powershot S90/S95 (1/1.7"), Ricoh GR Digital IV (1/1.7"), Nikon Coolpix P7100 (1/1.7"), Samsung EX1 (1/1.7"), Panasonic DMC-LX5 (1/1.63") and Olympus XZ-1(1/1.63"). Fujifilm FinePix X-10 has a 2/3" sensor, the largest sensor on camera small enough to be labelled as compact (despite weighing 353 grams) until June 2012. That is until Sony announced DSC-RX-100, a real compact (weight: 213 grams) equipped with a 1" sensor (i.e. one only used on MILCs until then). Actually, Canon labels "compact camera" its PowerShot G1 X, equipped with a huge 1.5" sensor (i.e. a sensor larger than the 4/3" sensors equipping some compact DSLR). Nonetheless, weighing well over half a kilo (534 grams) G1 X is arguably a bridge camera rather than a compact.
As of 2012 most bridge cameras, including the Sony CyberShot DSC-HX100V and the Canon PowerShot SX40 HS, use a small 1/2.3" sensor (i.e. same size as those used in common compact cameras). The high-end bridge camera Fuji XS-1, though, is equipped with a much larger sensor (2/3" – twice the area of a 1/2.3" sensor: see table further on).
The sensors of camera phones are typically much smaller than those of typical compact cameras, allowing greater miniaturization of the electrical and optical components. Sensor sizes of around 1/6" are common in camera phones, webcams and digital camcorders. The Nokia N8's 1/1.83" sensor was the largest in a phone in late 2011. The upcoming Nokia 808 surpasses compact cameras with its 41 million pixels, 1/1.2" sensor.

Famous quotes containing the words cameras and/or compact:
“Guns have metamorphosed into cameras in this earnest comedy, the ecology safari, because nature has ceased to be what it always had beenwhat people needed protection from. Now nature tamed, endangered, mortalneeds to be protected from people.”
—Susan Sontag (b. 1933)
“What compact mean you to have with us?
Will you be pricked in number of our friends,
Or shall we on, and not depend on you?”
—William Shakespeare (15641616)
