E-Donpisha: Enhanced asynchronous shutter. Available with external and internal synchronization modes. The camera CCD starts to accumulate electrons on receipt of an external trigger pulse. Shutter speed is selected by a switch or menu setting.

E-Donpisha - II: Asynchronous shutter mode. Available in external sync mode only. Timing of accumulation and shutter speed are controlled by the external trigger pulse. Shutter speed is selected by a switch or menu setting.

EIA (Electronics Industries Association): B/W video standard with 525 lines/frame, 2 interlaced fields/frame, 30 frames/second. Monochrome version of NTSC video signal. Also referred to as RS-170.

Electronic shutter: CCD camera operating mode where the integration time can be shortened without any mechanical device. Used for blur reduction when capturing fast moving objects, and for camera sensitivity reduction in high levels of scene illumination.

Exwave HAD technology: Technology with a nearly gapless OCL (On-chip-lens) located over each pixel of the CCD resulting in more than twice the sensitivity and 1/50 the smear compared to Hyper HAD technology.
