Shell Commands/PenCamTool

PenCamTool - Read out images from an USB webcam using the STV680 chip

TO/A, PICNUM/N, INTERVAL/N, UPTO/N/K, NOBEEP/S, GAMMA/K, SHARPEN/S, TEXT/K, FONT/K, FONTSIZE/N/K, UNIT/N/K TO - Mandatory filename to save the picture to PICNUM - Number of the picture to load from the camera's RAM, starting with 0 for the first picture. If no picture exists with this number, you will get garbage INTERVAL - If this numeric parameter is given, PencamTool will loop and take pictures at the given interval (in ticks, 50 ticks is one second). Interval is only sensible, if you don't give PICNUM argument UPTO - If specified, multiple pictures can be grabbed in one go, starting at the PICNUM number and stopping at the UPTO number. Be sure to give a format string such as "%ld" inside the filename or you will write all pictures to the same image. If no PICNUM is given, but INTERVAL instead, UPTO describes the image number to stop the regular picture taking NOBEEP - Disable BEEP on downloading an image GAMMA - Enable white balance and gamma correction with the give floating point gamma value. 0.45 is a good setting If you only want white balance and no gamma correction, use a value of 1.0 SHARPEN - Apply a highly optimized 5x5 sharpen filter on the image TEXT - Optionally adds the given line of text to the bottom of the picture. If the line is too long to fit, it will be truncated FONT - Name of the font to use (e.g. xen.font). If this parameter is missing, the default system font will be used FONTSIZE - Size of the font in pixels UNIT - If several cameras are connected, specify the unit to use. Defaults to unit 0.
