Digital camera manufacturer GE has launched a compact model with a built-in pico projector that beams photos, videos and other multimedia content onto almost any surface.

Although GE are by no means the first to produce a projector-cam, the company claims the PJ1 is the slimmest on the market at just 21.2mm thick and is capable of achieving big, bright projections.

The PJ1 uses Texas Instruments' DLP technology with a contrast ratio of 300:1 to deliver strong whites and blacks and bolder colours, and it has an aspect ratio of 16:9 and 15 ANSI lumens. In a darkened room the projection size can reach up to 70 inches (178cm).

As well as shooting and displaying holiday snaps and videos, the device can be connected to a laptop to use as projector for business presentations.

Focus is easily controlled by a sliding lever on top of the camera, while the rechargeable lithium-ion battery delivers up to 70 minutes of projection time - more than many stand-alone pico projectors can manage.

Aside from being a convenient portable projector, it is also a capable compact camera with 14.1 megapixel resolution, a 7 x wide angle zoom lens (28-196mm) and a host of features including automatic face recognition, exposure adjustment, smile and blink detection, red eye removal, pan-capture panorama and optical image stabilisation. Plus, to ensure camera settings are optimised for every scene, there are more than 25 shooting modes to choose from.

It also records 720p HD movies which can be instantly played back on the camera's wide three inch high resolution LCD screen.

A charging base can be used to stand the camera up during presentations and includes a concealed fan that cools the unit during prolonged use. The PJ1 also comes with a remote control.
