The HARP High-Sensitivity Handheld HDTV Camera
NHK Laboratories has developed a handheld HDTV camera with sensitivity ten times greater than HDTV cameras currently in use. The new camera allows shooting of darker scenes and covers a greater depth of field, and its small size makes it useful for shooting from various angles and at various locations. The high sensitivity is achieved through the use of HARP tubes and avalanche multiplication occurring in the HARP tube's target layer. Satisfactory signal-to-noise ratio (SNR) is also attained by employing GaAs field-effect transmitters (FETs) for the preamplifiers. In addition, on-line registration correction simplifies adjustment.
