A high frame rate camera includes; a multi-channel sensor array for producing a plurality of parallel analog image signals representative of a sensed image; a plurality of analog-to-digital converters (ADC) for converting each of the parallel analog image signals to parallel digital image signals, wherein each of the ADCs has a fine gain parameter which is a function of a top ladder potential and also has a fine offset parameter which is a function of a bottom ladder potential; and a control for controlling the fine gain and offset parameters of each of the ADCs by means of fine gain and offset control signals which are a function of desired average output black and gray levels of the image signal.

Automatic channel gain and offset balance for video cameras employing

Imaging apparatus includes a solid state sensor and a noise suppression circuit for suppressing noise in a video output signal generated by the image sensor.

Video signal noise suppression circuit

In a transversal filter equalizer, such as one using a tapped delay line, the present invention combines the symmetrically located pairs of tap signals, by means of adders and subtracters, to provide partial output signals which are separately controlled in amplitude and phase. These partial output signals, which have no d.c. components, are then summed with a partial signal derived from the center tap reference signal to reinsert the d.c. component and to provide the equalized output signal.
