White Paper 034 Addendum 49: Tests and Settings on a Ikegami MKC-300HD minicamera

Alan Roberts

Abstract

Data for this section is taken from the handbook and a very brief examination of an Ikegami MKC-300HD minicamera (serial number HA61119E) as part of a group test of HDTV mini-cameras. The model tested was a prototype, production models may vary significantly. The camera is connected via multi-core cable to a separate controller. There are no controls on the camera.

The MKC-300HD is a very small camera (34x34x40mm) and weighs only 100 grammes, but the controller is relatively large and weighs about 2.5kg. The specification claims that it has 3 CMOS sensors (⅓") of 2.07Mpixels, i.e. full 1920x1080. It has a C lens mount, standard amongst mini-cameras. Sensitivity is claimed to be F/10 at 2000lux, which is very high for 1920x1080 cameras with ⅓" sensors. The control unit has both digital outputs (HDSDI and DVI) and analogue, and separate SD outputs of composite, S-video and RGB. There are menus, allowing some image control.

The camera specification says that it will run only at 1080/59.94, but in the menus it was found possible to set it to 1080 or 720 format, at 50Hz and 59.94Hz. At 1080, only interlace is supported.

Power consumption is 60VA, mains only.

There are no controls on the camera itself.

Camera mounting was difficult, there are only two M2 screw holes for fixing. For the tests, it was held onto a tripod head with Velcro cable straps.
