Image processing apparatus, image pickup apparatus, and control method of image processing apparatus

An image pickup apparatus comprising:

• a first image sensor configured to acquire a first image by photoelectrically converting an optical image formed via a first optical system;
• a second image sensor configured to acquire a second image of a wider angle than the first image by photoelectrically converting an optical image formed via a second optical system;
• a display unit configured to display at least one of the first image and the second image;
• an estimation unit configured to estimate a gazing point position of a user on the display unit;
• and
• a control unit configured to control the display unit,
• wherein the control unit displays the second image on the display unit, and
• wherein when an angle of view frame of the first image superimposed on the second image and a display frame of the gazing point position in the second image overlap, the control unit switches from the second image displayed on the display unit to the first image.

An image processing apparatus comprising:

• a display unit configured to a display an image captured via an optical system;
• an estimation unit configured to estimate a gazing point position of a user on the display unit;
• and
• a control unit configured to change a zoom position of an image displayed on the display unit,
• wherein when the control unit determines that the gazing point position has been changed, the control unit changes the zoom position.
