Patent ID: 8817127

Claim:
An image capture device comprising: an imaging optical system for forming an optical image of a subject; an image capture element for converting the formed optical image into an image signal; a memory that stores the image signal obtained by the image capture element for one frame and is capable of reading out the stored image signal from any address; a feature detector unit for detecting a plurality of features contained in an image represented by the image signal for one frame based on the image signal obtained by the image capture element, and outputting positional information of positions of the features and a positional relationship of the features; a movement quantity detector unit that includes a positional relationship detector unit for storing the positional information of the features supplied from the feature detector unit, calculates a difference between the positional information of the features in the previous frame and the positional information of the features in the current frame as a vector based on the positional information of the features obtained for one frame, and detects movement quantities of the features; and a memory controller unit that controls an image read address from the memory in response to an instruction from the movement quantity detector unit, causes the memory to output an image in any position, and corrects a motion of the image to correct a change of a composition, wherein the movement quantity detector unit instructs the memory controller unit to read out an image from the memory in a direction eliminating the difference between the positional information of the features.
