Up until the past year, the sensors in HD video cameras were just barely enough in pixel count (2,073,600) to get 1920 x 1080 video. That has changed now, and camera manufacturers are putting sensors in their HD video cameras that have a much higher pixel count. The main reason is so that consumers can take high resolution snapshots with their video cameras, similar to the high resolution photos they can get from dedicated digital snapshot cameras. The serendipity is that the high resolution image can be downsampled to 1920 x 1080 rather than there being only just over 2 megapixels to start with, and this gives a sharper video image. The JVC GZ-HM400U is just such a camera, with its 10.3 megapixel sensor. Have a look at our review to see how it performed.
When the local Sony dealer asked me which model I wanted to check out, I wasn't sure if I should get the smaller 40" or the larger 46" model. On the one hand, statistics say that the 40" model will be a lot more popular, but they also suggest that the 44-50" segment, particularly in the US, is growing at an amazing rate.
