These days, if you have a cell phone, you're also likely to have a built-in digital camera. Some are certainly better than others, but in almost every case you have to ask yourself, Why would I need to purchase a stand-alone digital camera?

These days, if you have a cell phone, you're also likely to have a built-in digital camera. Some are certainly better than others, but in almost every case you have to ask yourself, Why would I need to purchase a stand-alone digital camera?

Good question. And the Nikon Coolpix S1000pj ($430 at circuitcity.com) has a very compelling answer. Can your phone project pictures onto a wall or ceiling?

While some cell phones and digital cameras can display their photos on a monitor or TV, Nikon has bragging rights as the first and, for the moment, only camera that doubles as a palm-size projector capable of displaying photos and movie clips as large as 40 inches, and from as far as six-and-a-half feet away.

The gadget also has a slideshow function that lets users set their pictures to music with an assortment of effects and transitions. Share pictures with your friends and family in this way and you're sure to earn their "oohs," "aahs" and envy.

The projector is the glitziest part of this gadget, but Nikon can't be accused of skimping on the actual camera.

The Coolpix S1000pj has a 12.1-megapixel sensor capable of shooting high-resolution pictures with lots of detail, making them suitable for printing photos as large as 16-by-20 inches. The camera's wide-angle lens is capable of a 5x optical zoom, as well as an additional 4x digital zoom.

Plus, there's an assortment of features to ensure in-focus pictures, including optical and electronic image stabilizers, motion detection that automatically adjusts the camera's shutter speed, and the ability to shoot 10 photos with a single shutter click and save the sharpest image.

Nikon also includes a skin-softening feature, smile shutter and blink warnings, an automatic red-eye fix and face-priority autofocus.

The S1000pj has 16 scene modes and can automatically adjust the camera setting to the proper one. Like many digital cameras, it can also shoot short videos at 30 frames per second and at a 640-by-480 resolution.

This 5.5-ounce camera has 36 MB of internal storage and accepts a SD/SDHC memory card to hold additional photos.

Yet despite all the reasons you can find to purchase Nikon's new camera, the main reason to own this gadget is the bragging rights of having a projector in your pocket.
