Moritex PVA
(Personal Video Assistant)
OverviewThe Moritex PVA is a next generation portable video image viewing and capture device. It will save both high res. JPEG stills and MPEG4 movie clips with sound. Based on an ARM processor and Linux OS the PVA uses the latest 4.3” OLED display technology with image capture (from both analog video and direct CMOS image sensor sources) to either an SDHC card or USB memory stick. Control comes from twin micro-joysticks linked to an intuitive user interface. The PVA comes in various standard versions to suit your application or it can be customised to your specific needs. Below are examples of typical applications: Video Endoscopy (OEM use)The PVA monitor section can be fitted to a video endoscope as the main image viewing and capture device (via a standard camera mount). In this application it would normally be supplied without battery handle and CMOS sensor and would capture analog video (either S-Video or composite) from the PAL or NTSC camera at the tip of the video probe. An external 5V PSU would be required to power the PVA. Images captured to the SD card can be transferred to a PC via a USB SD card reader. In future it will also be possible to use the PVA to capture USB 2.0 streaming digital video from a USB camera equipped videoscope via the PVA’s Type-A USB port (this requires the development of a suitable USB S/W driver). Upgrade for Optical BorescopeWhen supplied with a battery handle and CMOS imager chip the PVA can capture digital images directly from its image sensor. In this mode the Moritex PVA is also supplied with a C-Mount adapter for attaching lenses or an eyepiece coupler for connecting to the eyepiece of an optical endoscope or borescope. In this way any legacy optical inspection tool fitted with an industry standard eyepiece lens can be upgraded to become a digital video recording device with video display screen and image capture capability. Still images are captured at a resolution of 1024 x 768 whilst movie clips are recorded at a resolution of 640 x 480 pixels. The Li-on battery has an operating time in the order of 2 hrs. Cosmetic Skin ViewerThe Moritex PVA’s battery handle uses a plastic moulding, lens mount and CMOS image sensor common to the Moritex SCHOTT i-Scope device used for viewing skin in cosmetic applications. This means the PVA can be used in similar applications whilst offering fully portable viewing and image capture capability independent of a laptop PC. It can use the full range of standard i-Scope lenses and in this mode is supplied with integral LED illumination for both standard and polarized lighting options. As in the above industrial mode, the cosmetic version will display live video at NTSC resolution but with HD snapshot capture capability. Future upgrade options include specialised image processing software functions (written in C or Java) to run on the Moritex PVA’s Linux OS. Streaming USB 2.0 video output will also be possible with a suitable USB software driver installed. Download this information on the Moritex PVA, as a PDF document(128 KB)
