|||
||| I wonder why most of this software only allows the image to be
||| saved as a .bmp without a choice of saving as a .jpg.
|||
||| I have to admit that I'm not too up on these things technically,
||| but the resulting image I get from an image compressed down to even
||| 50k on my ancient 1.3mp Olympus digital camera is infinitely better
||| than what I'm capturing as a 300k .bmp using a cheap webcam or
||| security camera... all very
||| disappointing.
||
|| It's all down to the software and quality of sensor in the webcam.
|| Most webcam security software will allow the native .bmp to be
|| compressed to the lossy jpeg format for transmission by email,
|| ftp'ing to a 'live' window on a website etc.
||
|| The Sony CCDs are the best for low-light, but most webcams only
|| have CMOS sensors. Unfortunately the OP's QC5000 can come with
|| either CMOS or CCD sensors, but probably CMOS in the UK.
|| The resolution of the sensor is the other thing - most are 640x480
|| pixels, so images will never look as good as from a digital camera.
||
|| The current webcam of choice for low-light is the Philips SPC-900,
|| which uses the excellent Sony ICX098BQ CCD sensor.
||
I'm using a Philips SPC 300 camera, however its performance pales into
insignificance in comparison to my old Philips PCA645, which unfortunately I
can find absolutely no drivers for Windows 2000.
It delivers crystal clear pictures with drivers downloaded from Microsoft,
but unfortunately in daylight the resulting image is bright blue, due to the
fact that none of the set up menus for brightness, contrast, background or
gama are included along with the drivers.
