A control method for an image pickup apparatus that assists a manual focus operation during photographing of a video image by using an image pickup lens with a focus mechanism,

• the control method comprising:
• a display step of displaying the video image being photographed on a screen;
• a rendering step of rendering information on a focus of the image pickup lens on the screen;
• a first obtaining step of obtaining a current focus position of the image pickup lens during the photographing;
• a second obtaining step of obtaining a moving direction of the current focus position;
• a registration step of registering a focus position of the image pickup lens;
• a first highlighting step of, in a case that a first condition that a difference between the current focus position and the registered focus position is less than or equal to a first threshold value is satisfied, rendering first information as the information on the focus of the image pickup lens and performing a first highlighted display of the screen;
• and
• a second highlighting step of, in a case that a second condition that the difference between the current focus position and the registered focus position is less than or equal to a second threshold value smaller than the first threshold value is satisfied, rendering second information as the information on the focus of the image pickup lens and performing a second highlighted display of the screen, and
• wherein in the first highlighting step, the first highlighted display of the screen is performed based on the moving direction of the current focus position obtained in the second obtaining step and the focus position registered in the registration step.
