FIELD: physics, photography.
SUBSTANCE: invention relates to television and digital photography and more specifically to image stabilisation methods. The result is achieved due to that two additional linear photodetectors of considerably smaller area, made in form of rows (columns) are placed on a single crystal together with the main photodetector matrix, a signal is read from the additional two linear photosensitive devices with horizontal frequency many times greater than the frame frequency of the main photodetector matrix. The pixel size along the linear photodetector is selected such that it is several times less than the pixel size of the main matrix. To main equality of sensitivity of the main matrix and the additional linear photodetectors, in the latter the pixel size in the direction across reading is increased in proportion to reduction of the longitudinal size and reading time. Further, three video data streams are picked: one main one and two auxiliary ones, from which the shift of the crystal relative the image formed by the lens is calculated.
EFFECT: compensation for the effect of the shaking of the hands of the operator.
