Many improvements for a high speed camera including being able to process image data from a CCD array at one-quarter the pixel rate at which that image is provided by the CCD array; automatically demultiplexing color information in the digital domain; a high frequency, temperature compensated phase shift clock circuit to individually adjust the phase of the clock signal to each A/D converter; high frequency, high power analog, bipolar clock drivers to drive the horizontal functions of the CCD array since the necessary speed and power is not available in the horizontal driver section of commercially available CCD drivers; a technique to minimize the smearing of partial values of previous pixels into later pixels since the CCD array is being clocked faster than the internal time constant of the output stage of the CCD array; determination of, and compensation for, the dark reference (i.e., black level) offset of the pixel data streams from the CCD array; and subtracting the dark reference offset from the data pixel signal stream from the CCD array to stabilize the operating point of the output amplifier following the CCD array.

High speed, increased bandwidth camera

An apparatus and method for improving physical coordination and ability to react to moving and stationary objects is disclosed herein. A pair of voltage controlled liquid crystal lenses (14, 16) are mounted in a support frame (12) which is worn by a user in the same manner as conventional eyeglasses. The lenses (14, 16) can be electronically pulsed between an opaque state and a transparent state. Further, the lenses (14, 16) scatter background light in their opaque state rather than block the light so as to provide a generally constant level of contrast and brightness. This prevents pupil dilation changes when switching between the transparent state and the opaque state. Each lens can be made to pulse from an opaque state to a transparent state and then back again, and can be controlled independently or in synchronization. In operation, the user adjusts the control unit (18) to pulse the lenses (14, 16) at a high speed. An object is then viewed through the lenses and an appropriate response is made. As the user's proficiency increases, the user decreases the pulse rate and continues to react to the object. Reduction in pulse rate is continued until the desired level of reaction proficiency is achieved. When the apparatus is eventually removed, the user will be able to react to objects moving at higher speeds with greater proficiency. Additionally, in the case of both moving and stationary objects, the user's ability to concentrate will be increased.
