Abstract
Data for this section is taken from the handbook and a very brief examination of a Panasonic ‘POV’ (Point of View) mini-camera and recorder as part of a group test of HDTV mini-cameras. It comprises a camera head with integral lens (F/1.8, 4.0 to 48mm) and separate controller/recorder, recording on to SD or SDHC memory card.
The camera is small (53.5x56x123.8mm); the controller is 96x52.6x133mm and weighs about 580 grammes excluding the battery. The specification claims that the camera has 3 MOS sensors (1/4.1") but gives no indication of the pixel count. However, the specification claims that there are ‘approximately 2,510,000 effective pixels’, but it is not clear whether this refers to the sensors individually or collectively. Neither sensitivity nor noise levels are quoted. There are two versions, suffixed P and E, the only differences between the models appears to be the factory default settings relating to video format and system frequency. The controller has HDSDI input (for recording from an external source) and digital outputs via SD and HDMI. There are fairly comprehensive menus, allowing a considerable degree of image control. It has a significant range of operating formats, including native formats in which genuinely progressive video is recorded at the camera rate, with raising the delivery rate to 50 or 59.94 by pull-down algorithms:
- 1080i/50, 59.94
- 1080psf/25, 29.97
- 1080p/23.976 (native)
- 720p/50, 59.94
- 720p/23.976, 25 (native)
Power consumption is 1.75 Amps at 7.3V DC.
There are no controls on the camera itself. Unfortunately, the camera shows significant response to infra-red illumination.
