In this mode it is possible to use a lens with a video controlled iris. As for the timing, please refer to chapter 7.7 “Video output timing”. In continuous mode, exposure time can be controlled by the frame rate or by the electronic shutter.

  • Page 61: Image Processing

    11. Image processing 11.1. Basic construction The AT-140GE is a 3CCD camera equipped with F4, 1/2 inch prism optics. Red, green and blue color signals are taken from each of the 1.45-megapixel CCDs which have been filtered to the appropriate spectral wavelengths. A 32-bit microprocessor controls all functions in the AT-140GE camera.

  • Page 62: Auto White Balance

    11.3. Auto White balance The AT-140GE has 2 auto white balance modes: one-push auto white balance or continuous auto white balance. Both modes adjust the R channel and B channel using the G channel as the reference, in order to set all three channels equal.

  • Page 63: Gainauto

    The black level of the image can be controlled by 1 LSB step for 10-bit output. 11.6. Linear matrix The AT-140GE incorporates a linear color matrix circuit to improve color reproduction. Because this circuit processes signals in the linear stage, before the gamma correction circuit, the gamma circuit does not affect color reproduction.
