TL;DR: In this article, an automatic object image follow-up device includes a setting circuit for shiftably setting a followup field, an extracting circuit for extracting a feature of an object in relation to the follow up field, a store for storing the extracted feature and a detecting circuit for detecting a relative shift between the object and the device on the basis of the feature of the object extracted by the extracting circuit and the feature stored by the store.

TL;DR: In this paper, an automatic focussing system is described, which comprises an output circuit for sequentially outputting signals corresponding to a focus condition in a predetermined period, a prediction circuit for predicting a focus point by use of at least three signals outputted from the output circuit and a control circuit for controlling focus on the basis of the result of prediction by the prediction circuit when the difference of two signal outputs outputted by the predictor is below a predetermined value and when the levels of signals satisfy a predetermined condition.

TL;DR: In this paper, a lens position control device for an optical instrument, the instrument including a variator and a compensator, the latter of which also serves as a focusing lens, comprises a detecting circuit for detecting the positions of the variators and the focusing lenses, a memory for storing information representing the location and size of an impossible-to-focus zone for the focusing lens as the function of the zooming position of the variable, and a control circuit responsive to detection of the fact that the focus lens falls in the impossible to focus zone on the basis of the information stored

TL;DR: In this article, a control apparatus for an image blur prevention apparatus adapted to an optical apparatus having an optical device, light receiving structure for receiving light from the optical device and image processing structure for processing light received from the light receiving structures in accordance with an image processing condition to form a photographic image is described.

TL;DR: An image pickup apparatus as mentioned in this paper includes an image pickup element for photo-electrically converting an optical image formed on a pickup plane via an image picking optical system and outputting a picked-up image signal.
