An image processing apparatus includes an analysis unit for analyzing an image, an extraction unit for extracting a reference image corresponding to a specific object, and a first correlation calculation unit and a second correlation calculation unit for presuming an area having a high correlation in an input image by using the reference image. The first correlation calculation unit executes presumption based on components including a direct current (DC) component, and the second correlation calculation unit executes presumption based on an alternate current (AC) component, from which the DC component is eliminated. Based on at least any one of a detection result of the specific object, a feature amount of the specific object, and an analysis result of an imaging scene, acquired by the analysis unit, the first correlation calculation unit and the second correlation calculation unit are switched when the area is presumed.

Image processing apparatus that tracks object and image processing method

An image processing device detects a subject inside a captured image, acquires information of a first subject area and a second subject area that is a part thereof, and detects features of the subject areas. The image processing device calculates evaluation values from the detected feature points. If the second subject area is detected, control of displaying a display frame corresponding to the subject area on the display unit is performed. In addition, if the second subject area is not detected, control of displaying ranging position candidate frames as evaluation values to be displayed on the display unit is performed.

Image processing device, control method thereof, imaging apparatus, and program storage medium

An image-capturing apparatus according to the present invention includes: an image sensor; a gaze detecting sensor configured to detect a gaze of a user; and at least one memory and at least one processor which function as: an object-detecting unit configured to detect an object from an image captured by the image sensor; and a control unit configured to, if the object-detecting unit detects an object of a specific type in a case where a state of the gaze detecting sensor is a first state for detecting the gaze, change the state of the gaze detecting sensor to a second state in which an electric power consumption of the gaze detecting sensor is less than in the first state.
