Serial data transmission standard for computers which can also be used to control camera functions.
Industry:Consumer electronics
Capability of a camera to output a picture corresponding to an user defined sub-zone of the sensor. Applied in IEEE 1394 digital cameras featuring the Format_7 output option (XCD-X700, XCD-SX900).
Industry:Consumer electronics
Partial see-through mode on HMD allowing the user to view the surrounding environment by adjusting the transparency of the screen in the area only around the picture.
Industry:Consumer electronics
Asynchronous shutter mode used with external HD/VD sync. CCD starts to accumulate electrons when the external trigger pulse is received and stops when the VD pulse is received. Therefore the accumulation time (shutter speed) is decided by the length of time between the trigger pulse and VD input.
Industry:Consumer electronics
Lens iris aperture required to provide a video output signal of standard level at a specified light input. In general, sensitivity is measured using an 89.9% reflectance grey scale chart illuminated by a 3200∞K illuminance at 2000 lux (color camera) or 400 lux (B/W camera), for a video output level of 100%.
Industry:Consumer electronics
The ratio, usually expressed in dB (decibels), between the normal signal output and the noise level within an electronic signal.
Industry:Consumer electronics
Undesirable artifact of CCDs that appears in the picture as a vertical streak above and below a very bright object in the scene. Smear is caused by parasitic light getting into the vertical transfer registers. It is greatly reduced by the microlens-type of CCD used in Hyper HAD and Power HAD sensors. Almost suppressed in FIT CCDs.
Industry:Consumer electronics
Shutter mode with an integration time longer than 1/50 s (PAL) or 1/60 s (NTSC). Like long-term integration, the slow shutter function increases camera sensitivity when shooting slow-moving or fixed subjects. Unlike long-term integration, continuous normal video is output in slow shutter mode by use of a built-in video memory. The output picture is compatible with normal monitors and recorders.
Industry:Consumer electronics
Used to qualify a CCD sensor where the centers of the pixels are equally spaced horizontally and vertically. Pictures captured from this type of non-square pixel sensor need to be software corrected in order to achieve the correct picture geometry.
