MEL-1254A 型512(垂直)×383(水平)象素 CCD 摄象器件是采用两层多晶硅的重叠电极结构,四相驱动,帧转移方式工作。受光部分尺寸为垂直6.656×水平8.426毫米,用2/3英寸光学系统。芯片尺寸为垂直13.62×水平10.3毫米,装在透明玻璃密封的28脚陶瓷双列直插式管壳内。象素尺寸垂直26×水平22微米。为防止芯片外围光透入,采用设置转移沟道低阻化多晶硅等方法。单价25万日元。使用这个器件的黑白摄象机 BS-701型价格为55万日元。最低照度50勒克司(F1.4,
MEL-1254A type 512 (vertical) × 383 (horizontal) pixel CCD camera device is the use of two layers of polysilicon overlap electrode structure, four-phase drive, frame transfer mode work. The size of the light-receiving portion is vertical 6.656 × horizontal 8.426 mm with a 2/3 inch optical system. The chip size is vertical 13.62 × horizontal 10.3 mm, mounted in a clear glass sealed 28-pin ceramic dual in-line package. Pixel size vertical 26 × horizontal 22 microns. In order to prevent chip peripheral light penetration, using the transfer channel low resistance polysilicon and other methods. Price 250,000 yen. The black-and-white camera BS-701 model using this device costs 550,000 yen. Minimum illumination 50 lux (F1.4,
