Casio's Latest in Point-and-Shoot Digital Cameras

by Terrence O'Brien, posted Jan 7th 2008 at 11:29AM

Casio Updates Exilim Digicam Line
Casio announced an update to its line of top notch and fashionably slim Exilim point-and-shoot digicams at a press conference yesterday. The new EX-S10, EX-Z80, EX-Z100, EX-Z200 add some fancy new features and a bevy of new color choices.

The EX-S10 is "the world's smallest and slimmest" 10-megapixel camera, and adds iTunes (read iPod/iPhone/iPod Touch) compatibility to Casio's existing YouTube capture mode for easy transfer of your videos and photos. The S10 also adds a one-button video feature, so you don't have to dig through menus or turn any knobs to capture video as you do with most other cameras, just hit the separate capture button and start shooting full motion video. Lastly, but certainly not least(ly), the new camera also gets some fancy auto shutter technology that makes it much easier to capture that perfect image because it lets the camera wait until subjects are stationary or centered in frame before snapping that photo.

The other three cameras announced today build on those features. The Z80 adds face detection to the auto shutter line up. While the Z100 and Z200 and wide angle lenses, and higher optical zooms (4x). The Z200 distinguishes itself from the Z100 by adding image stabilization.

All the new cameras are available in a variety of model specific colors on top of the standard silver and black. Check out the Z80's lime green shade, and the Z100's brown tint. It's always good to have options.

Public Audio Surveillance Hits London

by Terrence O'Brien, posted Oct 23rd 2007 at 7:25AM

London Police Love Their Surveillance
Everyday this Big Brother stuff gets scarier and scarier. Pretty soon the only place you'll be safe is in your own home, in your bed room, under the blanket. We posted before about experts declaring that by 2057 there will be roughly one million sensors and recorders for every U.K. resident. It looks like London is wasting no time rushing towards that goal.

We're well aware of the security cameras already all over the city, but it looks like Londoners will also have to brace themselves for audio surveillance, too. In order to break up gangs, London police have begun a program using audio bugs placed in public places.

Currently, the listening devices have only been deployed in Lambeth, in south London, where youth gangs are particularly prevalent, and where gun crime has risen 10 percent in the last six months. The hope is that the intelligence gathered will help authorities identify key figures in the tight-knit, but loosely organized groups, which will better allow police to disrupt their activities.

Public eavesdropping, sans warrants, by law enforcement is sure to rankle some privacy advocates. Authorities are hoping a drop in crime will quell the inevitable uproar. We shall see.

Would you approve of audio eavesdropping if it reduced crime in your area?

Heat-Sensing Cams Police Commuter Lanes

by Tim Stevens, posted Oct 4th 2007 at 12:17PM

Heat-Sensing Cameras Police D.C. Commuter LanesIf you've ever considered installing an inflatable dummy in your passenger seat so that you can use those temptingly fast-moving commuter lanes on the highway, you might want to think again -- at least if you live near Washington D.C. There local officials are installing infrared cameras to identify cars with too few passengers on board. The cameras will take body heat readings of a car's interior to determine how many occupants are inside. Too few people and a ticket will be automatically generated.

So, if you are going to use that inflatable dummy, at least make sure you fill it with warm water before hitting the highway. Just don't blame us if it springs a leak and gets your fancy new dash unit all wet.

Just for fun:

Surveillance Cams Don't Reduce Crime, Study Finds

by Terrence O'Brien, posted Sep 21st 2007 at 1:30PM

Surveillance Cameras Not Effective at Solving CrimesStatistics obtained by the British Liberal Democrats Party through the Freedom of Information Act (yes, they have one, too) show that even with over 10,000 cameras in various London boroughs, 80 percent of all crimes still go unsolved. In fact, when broken down by borough, there is no correlation between the number of cameras and the percent of crimes solved.

  • There are now 10,524 CCTV cameras in 32 London boroughs funded with Home Office grants totaling about £200million.
  • Hackney has the most cameras -- 1,484 -- and has a better-than-average "clear up rate" of 22.2 per cent.
  • Wandsworth has 993 cameras, Tower Hamlets, 824, Greenwich, 747 and Lewisham 730, but police in all four boroughs fail to reach the average 21 percent clear-up rate.
  • By contrast, boroughs such as Kensington and Chelsea, Sutton and Waltham Forest have fewer than 100 cameras each, yet they still have clear-up rates of around 20 per cent.
  • Police in Sutton have one of the highest clear-ups with 25 per cent.
  • Brent police have the highest clear-up rate, with 25.9 per cent of crimes solved in 2006-07, even though the borough has only 164 cameras.

After 10 years and £200 million of tax payer money, groups like the criminal justice charity Narco are questioning whether the money would have been better spent on more street lights, which can cut crime by up to 20 percent.

Even the scariest of stories about government and police surveillance usually end with the good guys catching the bad guys, which makes the "Big Brother" theories a little less ominous. We don't mean to burst your bubble or anything, but as this story shows, that doesn't always happen.

Do More Megapixels Make Better Pictures?

by Tim Stevens, posted Sep 18th 2007 at 2:04PM

How Mexapixels Measure UpWith many things digital, more is better: More gigabytes of space, more gigahertz of speed, more inches of LCD, more hours of battery life, the list goes on.

When it comes to cameras, we all think that more megapixels are better ... or are they? Photography site Imagine 123 has taken an objective look at the "bigger is better" mantra when it comes to digital cameras and megapixels in a new guide that tell you just what you need. The results are surprising.

What's A Megapixel?
A megapixel is a million pixels and it's used to measure how sharply defined the images coming out of your digital camera are. While more megapixels doesn't necessarily mean a better looking picture, it will mean a sharper one that can be printed at larger sizes. However, the more megapixels a camera's image sensor packs, the smaller those individual pixels on that sensor are. Smaller pixels on the sensor generally require more light than those on a larger sensor, meaning longer shutter times, more chance of a blurry picture, and greater signal noise (seen as digital looking fuzz in the picture).

So How Many Megapixels Do You Need?
When it comes to printing, high quality prints are at 300 pixels-per inch. Do the math (as Imagine 123 did) and a 2 megapixel camera like that found in the iPhone can't take adequately high resolution shots for a 4x6 print. To do a proper 8x10 you would need a 12-megapixel camera -- quite a jump. But, if you don't plan on making large prints, don't cough up the extra dough for a high-end cam with a double-digit megapixel count, especially if your subjects aren't always brightly illuminated. Today's basic 4-megapixel camera can produce great looking 5x7 prints even in low light.

But, these days you may be hard pressed finding anything that low. Even pocketable cams like the FujiFilm Z10fd deliver 7 megapixels in their diminutive forms, while Kodak's somewhat more pedestrian-looking $99 C513 sports 5 megapixels.

So, don't suffer from megapixel envy. After all, as every serious shooter knows, it's the photographer who makes great pictures, not the camera.
