The controls are minimal and simple. The OK/MENU button calls up the onscreen menu system and once displayed it acts as the "accept" button. The button to the right turns the LCD on/off when in Record mode and acts as the Play button when the lens cover is closed. Sliding the lens cover open turns the camera on in Record mode and closing it turns the camera off.

The 4-way buttons are multi-purpose, when the menu is displayed they let you navigate the options, when in Play mode they let you select images from the thumbails or move forward or backward or zoom-in or display the index. When in Record mode the Up and Down buttons control the digital zoom (in Play mode they enable zoomed or index mode), the Right button selects the flash mode.

The D-370 has an all-glass, fixed-focus 4.5mm f4 Olympus lens with a variable digital zoom up to 2X (35mm to 70mm equivalent in 35mm photography). The normal focus range is 0.6m inches to infinity, the Macro mode covers from 0.25m to infinity.

The eyelevel optical viewfinder shows about 94% of the captured image and lets you use this digital camera just like a regular film camera. The LED lets you know the status of the flash and camera.

On the side are the I/O ports. On top is the DC IN jack for connecting an optional AC power adapter.

On the bottom is the USB port, the D-370 features USB AutoConnect technology. Just plug the camera directly into any USB-configured computer running Windows 2000, Windows Me and Mac OS 8.6 and higher, these computers will mount and recognize the Brio D-370 automatically without installing drivers. For users with Windows 98 the necessary USB drivers are included on disc.

The D-370 does not have a video out feature.

Images are stored in the D-370's internal 2MB of memory or on optional 3.3v SmartMedia flash memory cards. Any size card up to 128MB may be used.

The D-370 is powered by either two Olympus CR-V3 lithium (supplied) or by four standard AA size batteries (alkaline, lithium, NiMH type).
