Canon Legria HF20

Colour (8.31)

Our colour tests didn't reveal anything too unusual with the Canon HF20. It scored a decent 4.21 colour error with a saturation of 91.5%. This is an average score and it's a bit lower than the elite numbers we got from the Sanyo VPC-HD2000 and Canon HF S100. Looking at the colour error map below, you can see the HF20 did very well with dark blues and purples, but faired poorer with reds, pinks and some greens. (More on how we test colour.)

Colour Accuracy Performance
Colour Chart with Error Chart to the right
The Canon HF20 produced a colour error of 4.21 and a saturation level of 91.5% in our bright light colour testing. (The map on the right is a diagram of the colour error and the direction the camcorder skewed each colour for each patch on the chart.)

The Canon HF20 produced a very pleasing image at 3000 lux. Lines were sharp and colours were very well defined. Whereas the Sanyo VPC-HD2000 showed a warm, yellow tone in its image, the Canon HF20 had a cooler, bluish hue. We must say, the HF20 captured very pristine text and extra-fine detail—often rivalling the image quality seen on the more expensive Canon HF S100.

Canon HF20 colour Modes
Auto	100% Crop
Image Effect Vivid	100% Crop
Image Effect Neutral	100% Crop
Image Effect Low Sharpening	100% Crop
Image Effect Soft Skin Detail	100% Crop

The Canon HF20 has a number of pre-set Image Effects—Vivid, Neutral, Low Sharpening, and Soft Skin Detail. Each of these does a decent job adding an extra element to the video image. If that's not enough for you, there is also a customisation setting that lets you create your own effect by adjusting colour depth, brightness, contrast, and sharpness. Canon does not offer much room for experimentation, however, as each setting only has a full adjustment range of +/-1.

The Canon HF20 showed a very similar overall image to its big brother, the Canon HF S100. The Sanyo VPC-HD2000 also had a nice image, although lines didn't pop nearly as much as we saw on the two canons. The Panasonic HDC-HS20 was a notch below the rest, with blurry text, soft lines, and plenty of artefacting. The colour accuracy of all four camcorders were good, with the VPC-HD2000 and Canon HF S100 leading the way.

In the colour chip close-ups above, you can see the differences between the Canon HF20 and the rest of the camcorders we tested. All the camcorders show a slightly darker image than the 'ideal' colour, but this is normal because camcorder manufacturers tend to oversaturate the video image in order to produce more vivid colours.

Colour Performance Scores

Overall, the Canon HF20 had decent colour accuracy in bright light and its video image looked very sharp. Other camcorders in this group measured more accurate colours, but the differences were not that significant. Worth notable mention is how well the HF20's bright light image compares to the more expensive HF S100. Both camcorders put up very similar results in our bright light testing.

Noise (8.68)

The Canon HF20 registered a fairly high level of noise, averaging roughly 0.70% in our bright light testing. Canon usually has high noise levels on its HD camcorders. Surprisingly this numbers are a lot better than the noise level of the more expensive HF S100. Keep in mind, however, that in bright light this noise can be difficult to notice. It's really not until you start recording in low or moderate light situations that it becomes a problem. Also, the high noise levels on the HF20 seem to be directly related to the fact that its image is so darn sharp. The impeccable detail and high resolution appears to boost the level of noise. (More on how we test noise.)

Looking at the crops above you can see the level of detail we are talking about. Take a glance at the numbers running down the left side of each frame and notice how much easier they are to read on both Canon camcorders as compared to the Panasonic and Sanyo models. The Canons also show higher levels of contrast, which gives their images more pop. All these things factor into the higher noise levels present on the Canon HF20 and HF S100. The Sanyo VPC-HD2000 finds a happy medium—it has a relatively detailed image with rather low noise levels. The Panasonic HDC-HS20 has the blurriest image, but it also recorded the least amount of noise. This is mainly because everything in its frame is so soft and the image captures a low amount of detail.

Noise Score Comparisons

We score this section based on the noise levels we measure in the video image. So, even though the Canon HF20 showed us a great picture, the Panasonic HDC-HS20 wins this round (it measured 0.4175% noise). Check out the Video Resolution section of our review to see the HF20's impeccable performance in that arena.
