i was referring to camera phones. early camera phones had options to turn shutter off. then around i cant remember the year the shutter sound option was removed from every mfg.
edit its not 100% fool proof their are way to hack around the sound, make a call etc, but the phone idle, camera on it will make a shutter sound.
my g9 powershot and other digital camera's i can turn shutter sound off, but people see i have a camera in my hand unlike seeing a phone.
from the wiki and i remeber most companies agreeing to remove the shutter setting.
Camera phones have had a broad social impact over the past decade. In a recent radio interview, Philippe Kahn discusses the social impact of the camera phone . |
While camera phones have been found useful by tourists and for other common civilian purposes, as they are cheap, convenient, and portable; they have also posed controversy, as they enable surreptitious photography. A user may pretend to be simply talking on the phone or browsing the internet, drawing no suspicion, and be able to photograph a person or place illegally or against that person's wishes.
As a network-connected device, megapixel camera phones are playing significant roles in crime prevention, journalism and business applications as well as individual uses. They are also prone to abuse such as voyeurism, invasion of privacy, and copyright infringement. Because they can be used to share media almost immediately, they are a potent personal content creation tool. On January 17th, 2007, New York City Mayor Michael Bloomberg announced a plan to encourage people to use their camera-phones to capture crimes happening in progress or dangerous situations and send them to emergency responders. Through the program, people will be able to send their images or video directly to 911.
Enforcing bans on camera phones has proven nearly impossible. They are small and numerous and their use is easy to hide or disguise, making it hard for law enforcement and security personnel to detect or stop use.
From time to time, organizations and places have prohibited or restricted the use of camera phones and other cameras because of the privacy, security, and copyright issues they pose. Such places include the Pentagon, federal and state courts (see, for instance, ), museums, theaters, and local fitness clubs. Schools have banned them over the concern that they could be used to take images of notes that can be used in order to cheat on exams. One country, Saudi Arabia, in April 2004, banned the sale of camera phones nationwide for a time before reallowing their sale in December 2004 (although pilgrims on the Hajj were allowed to bring in camera phones). In South Korea and Japan, all camera phones sold in the country must make a clearly audible sound whenever a picture is taken: These laws are intended to reduce the number of up-skirt photos taken. In Singapore, camera phones are banned at companies or facilities that have an association with national security. In Europe, some BDSM conventions and play parties ban cellphones altogether to prevent camera phone abuse.
this is why basically camera shutters dont have an option to be turned off in a cell phone only.
