IB Reduction
On TVs that use 100Hz and 200Hz technology, a blurring effect can occur when the previous frame has not fully removed before the new frame appears. This algorithm helps to reduce the effect.
Intelligent AI LCD
This function automatically determines the brightness of the scene shown on the LCD and adjusts the brightness of the backlight in real-time. It displays images with crisp contrast according to the actual scene (darker for dark portions, brighter for bright portions).
Interlaced Scan
It uses two fields to create a frame. One field contains all the odd lines in the image; the other contains all the even lines of the image. A television that scans 50 frames every second (25 odd and 25 even) would have two sets of 25 frames combined to create a full frame every 1/25th of a second, resulting in a display of 25 frames per second. Drawbacks to interlaced scanning compared to progressive scanning include flicker, lower resolution and quality issues.
Inverter Technology
Unique to Panasonic microwave ovens, the conventional transformer and capacitor have been replaced with an Inverter circuit board. This has many benefits including reducing the weight of the oven, maximising the cooking capacity and most importantly; due to better power control, improving the cooking performance.
IPS
In-Plane-Switching. It was co-developed by key manufacturers including Panasonic, Hitachi and Toshiba. IPS mode system technology is used in TFT LCD displays. It delivers a very wide viewing angle of up to 170 degrees, both horizontally and vertically, with minimal greyscale inversion (i.e. when the screen starts to look blacked out when viewed from the sides). IPS works because the liquid crystal molecules inside the display rotate and therefore remain parallel to the substrate when voltage is applied.
IPTV
Internet Protocol Television delivers multimedia services through an IP based network, such as the internet, and can include live television, catch-up TV and video on demand. BT Vision and Virgin TiVo are examples of IPTV.
Iris Adjustment
To achieve special creative effects or to cope with special lighting situations the iris (F-number) can be adjusted manually to let in more light.
ISO (Sensitivity)
A value used to indicate a film’s sensitivity to light. ISO also stands for the International Standards Organization. Since no similarly defined standard exists for digital cameras, the term ‘ISO 100 equivalent’ is used. A larger ISO value indicates that the camera can take a better picture in dimly lit locations (such as indoors).
