Modern digital still cameras, TV cameras, and movie cameras typ- ically have a liquid crystal display (LCD) image display to allow direct viewing of the image. A typical technology for these displays utilizes low-temperature polycrystalline silicon thin-film transistor (TFT) LCDs. The image aspect ratio of these displays is AR = L WLCD /L HLCD . For the Canon models S230, SD550, and SD630 digital cameras, the aspect ratio is the same as the aspect ratio for the charge-coupled device (CCD) sen- sor. (See Digital Camera - CCD Image Sensor.) The quantities L WLCD and L HLCD are shown in the figure below....
