Re: Can't see me during night time even there's is light
Several factors determine onscreen size of a video image produced by a Webcam. The actual Webcam hardware may be limited to a maximum resolution. The percentage of your screen filled by a Webcam image will be a factor based on your desktop resolution and the maximum resolution of the Webcam image. A third factor impacting image size is available bandwidth Webcam software may also play a role in determining image size, but in most cases the software is only limited by the Webcam output. There are several ways to optimize your results to make sure you send a Webcam image viewable at the highest resolution acceptable to relatives on the other end, while also optimizing your system to maximize available screen real estate with inbound images from relatives.
Webcam hardware is often a big limiting factor in determining maximum image size. Most Webcams on the market today output a maximum 640x480 image, which easily fills a television screen. Any of the Webcams currently available from Logitech, Creative, Apple, D-Link or the numerous niche companies marketing Webcams will support 640x480, although some produce better results than others. If you have a Digital Video camera capable of doubling as a Webcam, you may get a 720x480 maximum image size. Apple's iSight camera and some of the higher end Logitech cameras using CCD instead of CMOS image sensors produce excellent images at 640x480 in well-lit rooms.
Knowing 640x480 is the maximum image size, don't expect incoming video to fill your screen if you have your resolution at 1024x768. The graphic below is shows the relative portion of a 1024x768 screen filled by a 640x480 image at 50% of actual size. If you want the incoming video to fill your screen, reset the resolution of your monitor to 640x480 to properly accommodate the incoming video feed. This assumes your relatives are capable of sending 640x480 video from their end. If their sending limitation is 320x240, the best you can hope for is a video filling 50% of your 640x480 screen.

I'd forget Windows 10 if I were you. Information on you is collected and sent to Microsoft even if you turn them all off during installation. Nobody gets to spy on my computer. That's why I won't upgrade to 10. As for drivers, you may have to go to Micro Innovations website for drivers , if they even have them. I have a perfectly good dye sublimation printer I cannot use on anything later that win 98 because of the lack of drivers.
This document is located on HP's web site concerning purple tint on certain web-cams. This document pertains to certain HP Notebook PCs with Windows 7. When using an HP ENVY 15 notebook PC webcam in low light conditions, images on the webcam may have a purple tint.The ENVY 15 Series webcams include night vision technology that is designed to operate in normal lighting conditions and optimized to operate in low and zero light conditions.The webcam night vision feature includes two Infrared (IR) lights located on each side of the webcam and behind the display panel bezel. Low to zero light conditions will cause the webcam IR lights to activate. The IR lights provide illumination for low and zero light conditions and help prevent fuzzy images that are typically associated with operating standard webcams in low and zero light conditions. Turn off the webcam IR lights. While some degree of purple tint may be present under low light conditions, turning off the webcam IR lights will reduce and in certain cases eliminate the purple tint.
Select Start > All Programs > HP > HP MediaSmart > HP MediaSmart Webcam .
In HP MediaSmart Webcam, select Settings > Display > Advanced Settings , and then click the Camera Control tab.
Select the Low Light Compensation check box, and then click Apply .
Click OK .
NOTE:Disabling the webcam IR lights will cause display images to appear darker in low and zero light conditions. The webcam IR lights are also available on other webcam programs. Refer to the software Help for additional information. This document will be updated if additional information becomes available.
Taking pictures at night is just like taking pictures during the day, except it's darker. In order to get enough light to the image sensor, you need to either increase the sensor sensitivity (increase the ISO), open up the aperture (smaller f/numbers), use a longer exposure (which may require putting the camera on a tripod or other stable platform), or a combination of the three. Or put more light on the subject, perhaps by using the flash.
The flash on your camera doesn't put out very much light (when compared to the sun). You can't use it for subjects far from the camera, or when you want things at different distances illuminated evenly.
You didn't state the model of your camera so I'm afraid I can't tell you how to change any of the three settings I mentioned in the first paragraph.
Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(
If you are using digital zoom, not optical, the image processor in the camera has to extrapolate data from the surrounding pixels. In good light, this gives acceptable results, but at night when (as you may have noticed) it is darker, it encounters problems and does the best it can.
Not sure if this applies, but this is on the Morovision site: http://www.morovision.com/faqs.htm Because of the manufacturing processes, all night vision image tubes will have different cosmetics such as small spots or specs, photocathode coloring, or a chicken wire effect from the microchannel plate. Most cosmetics are only noticed during viewing in high light situations such as viewing with the daylight filter on in a lit room. Most cosmetic blemishes are not noticeable during normal nighttime operation but may still be seen to some degree in certain situations. These cosmetics in no way effect the performance of the image tube and do not decrease the ability to perform nighttime tasks.
