Pictures messed up between camera and computer

Try NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa ( http://picasa.google.com ).

The manual only can give two reasons why the camera would not take pictures.
One, there is no memory card placed.
Two, the memory card is full.
You are sure you have placed a working empty memory card.
If you did save all the pictures on the memory card to a computer, try formatting the card in the camera.
When you are pressing the shutter release button half, does the camera say it is focused correct? light bottom corner of the display.
Your camera has a setting to take pictures with a remote control. Did you put the camera in that setting? Read page 76 of the manual.

Since you declined to specify the model of your Aiptek camcorder, I can only direct you here to look for the manual.

Sometimes the camera just has a problem. Put the memory card into your computer without taking more pictures or messing with it on your camera. The computer usually will read the file error pictures just fine.

Try plugging the camera into the computer and take all the pictures off of it, then unplug it and go into the camera menu. Once there, select "format memory card". WARNING: this will erase all pictures currently on the camera, so be sure to take them off it first. -G

I believe you want to take the pictures "off" your computer, not pictures "of" your computer.

You may or may not be able to do this, because several camera manufacturers implement some JPEG extensions to make their pictures more easily managed by the camera.

For example, Casio, Canon and Sanyo digital cameras actively employ thumbnails to render pictures in the camera's previewer. If you edit or create a JPEG picture on the computer, chances are that it will not have the proper EXIF tags, JPEG thumbnail, and/or Maker Notes to allow the camera to "see" the JPEG as one of its own pictures.

I can't be more specific than this because I never did try with a Sanyo camera; I did try and succeed after a bit of experimentation using ExifTool and EXIFEdit, which you can download from here:

...what you need to do is, get a picture off the camera, analyze it, then analyze a picture from the computer and set all the proper fields so that the computer picture has the same tags and values as the camera one; then try putting it back on the camera's memory card, or through the USB connection as storage device if one is available, and see whether the camera was indeed fooled.

Hope this helps, let me know...

It sounds like it may have reformatted itself and if thats the case, they are gone. Some camera's have the option built in, then again, your computer might have done it when plugged into the card reader. I hope this can help shed some light on what may have happened, but sorry to say, if the memory card is now empty, chances are slim on recovering the pics.

Unfortunately Windows in particular can mess with the contents of the card just by reading it - it creates a thumbnails file on the card without asking etc etc.
It shouldn't mess with the actual pictures unless you have rotated them or perhaps removed the card without safely removing the hardware first.
Try reformatting the card on the camera and you should be good to go from there.
