FIELD: physics.
SUBSTANCE: image is detected by a two-dimensional array of optical sensors. The signal of the detected image is converted to a data structure in form of a two-dimensional matrix of pixel values which indicate the amount of light picked up by the optical sensors. A blurred image is generated by combining a selected pixel value with pixel values of its vicinity. The selected pixel value is compared with the corresponding pixel value of the blurred image to determine the degree of focusing and visual indication of the degree of focusing is provided.
EFFECT: providing visual indication of the degree of focusing.
