ABSTRACT:
Light energy data is generated in sequential interlaced field raster format y a sensor driven in azimuth to detect a panoramic scene. The light energy data is sequentially recorded together with an azimuth rate signal which is a function of the rate that the sensor is driven in azimuth. Because the sensor has been driven in azimuth, however, there is a delay in the sequential detection between first and second interlaced fields of any selected frame of the panoramic scene; consequently, when it is desired to retrieve and playback a "stop-action" image comprised of a selected frame, compensation must be made for the delay. The recorded azimuth rate signal is used to develop a commensurate delay between the two sequential first and second interlaced fields of light energy data comprising the selected frame of light energy data which is desired to playback in "stop-action" form. The delay period thus developed is applied to correct the delay between the first and second interlaced fields so that visual display means, such as cathode ray tube monitor, may display the "stop-action" playback of the selected frame in a corrected form, eliminating the "jitter" that otherwise would be visually present between first and second interlaced fields due to the sequential field rate of the raster format in which the light energy data is recorded relative to the azimuthal rate at which the sensor was driven.
