1200 Lux picture: This recording at about 1200 lux is primarily a comparison of the color reproduction with factory settings. But of course you get a good overall impression of the imaging performance of the camera in very bright conditions.
12 Lux picture: Here you can see how much image information the camera is able to record in very low light (approximately 12 lux). In addition to a decrease in the sharpness you often see much noise, decreasing colors, chroma-stains and other artifacts.
Horizontal brightness resolution / Luma This chart shows the horizontal sharpness of the luma channel using a sweep. The later the curve narrows, the sharper is the camcorder. A sharp hump in the curve towards the right is a sign for artificial sharpening.
Horizontal chroma resolution This chart shows the horizontal sharpness of the chroma channel using a sweep. The later the curve narrows, the more accurate the camera can distinguish between colors.
Distortion: The distortion of the lens is measured at the maximum wide-angle. The straighter the lines, the better the image.
ISO: This is an excerpt of the typical ISO 12233-test chart. The narrowing "trumpets" show how far the sharpness of the camera goes. At the finer circle lines moirés can be visible.
Audio: For reasons of comparability, only the internal microphone of the camera is measured. The smoother the curve and the farther down in the graph, the better the noise behavior of the audio recording.
Here you can directly compare test charts of two camcorders.
Just choose a model in the two drop-down menues and define via mouse-over which test chart is to be shown.
