Claims (16)

Imaging means for imaging the subject,
A first display mode in which an image signal of a predetermined screen corresponding to the image pickup unit is displayed on the display unit, and a second display mode in which a part of the image signal of the predetermined screen corresponding to the image pickup unit is displayed on the display unit. Switching means for switching between display modes,
A flicker detection unit that detects flicker of illumination light of the subject by using an image signal output from the imaging unit;
Setting means for setting a flicker reduction shooting mode for capturing an image of a subject and obtaining an image in which the influence of the flicker is reduced,
An exposure control means for controlling at least an exposure time of the image pickup means in order to acquire an image with the flicker reduced in the flicker reduction photographing mode,
In a state in which the flicker reduction shooting mode is set by the setting unit and the second display mode is set by the switching unit, the exposure control unit does not depend on the result of flicker detection by the flicker detection unit. An imaging device, wherein the exposure time of the imaging means is controlled to an exposure time that reduces the influence of the flicker. The image pickup apparatus according to claim 1, wherein in the first display mode, the image pickup unit thins out and outputs a predetermined pixel from pixels of the predetermined screen corresponding to the image pickup unit. The image pickup device according to claim 1, wherein in the second display mode, the image pickup unit outputs the part of the image signals without thinning out. The image pickup apparatus according to claim 1, wherein in the second display mode, the part of the image signal is enlarged and displayed on the display unit. The exposure control means acquires an image in which the influence of the flicker is reduced by controlling only the exposure time of the imaging means when no flicker is detected by the flicker detection means. The imaging device according to claim 1. The image pickup apparatus according to claim 5, wherein the exposure control unit acquires an image in which an influence of the flicker is reduced by making an exposure time of the image pickup unit longer than a period of the flicker. The said exposure control means acquires the image which reduced the influence of the said flicker by controlling the exposure time and exposure timing of the said imaging means, The any one of Claim 1 thru|or 4 characterized by the above-mentioned. The imaging device described. When the flicker is detected by the flicker detection unit, the exposure control unit controls an exposure time and an exposure timing of the image pickup unit to acquire an image in which the influence of the flicker is reduced. The image pickup apparatus according to claim 7. The flicker detection unit detects the flicker using the partial image signal in a state where the flicker reduction shooting mode is set and the second display mode is set. The image pickup apparatus according to claim 1. 10. The image pickup apparatus according to claim 1, wherein the flicker detection unit detects the flicker by two types of methods. The flicker detection means detects the flicker by dividing an image shot with an exposure time shorter than the flicker cycle by an image shot with the same exposure time as the flicker cycle; The flicker is detected by a second method of detecting the flicker based on a change in an integral value of each of a plurality of images captured with an exposure time shorter than the flicker cycle. apparatus. 12. The flicker detection means detects the flicker by the second method when the flicker is not detected by the first method in the second display mode. Imaging device. 13. The image pickup apparatus according to claim 12, wherein the flicker detection unit detects the flicker by the second method after switching from the second display mode to the first display mode. A method for controlling an image pickup apparatus including an image pickup means for picking up an image of a subject, comprising:
A first display mode in which an image signal of a predetermined screen corresponding to the image pickup unit is displayed on the display unit, and a second display mode in which a part of the image signal of the predetermined screen corresponding to the image pickup unit is displayed on the display unit. A switching process for switching between the display mode,
A flicker detection step of detecting flicker of illumination light of the subject using an image signal output from the image pickup means;
A setting step of setting a flicker reduction shooting mode for capturing an image of a subject and obtaining an image in which the influence of the flicker is reduced,
An exposure control step of controlling at least an exposure time of the image pickup means in order to acquire an image in which the flicker is reduced in the flicker reduction photographing mode,
In the state where the flicker reduction shooting mode is set in the setting step and the second display mode is set in the switching step, the exposure control step does not depend on the flicker detection result in the flicker detection step. A method for controlling an image pickup apparatus, comprising: controlling an exposure time of the image pickup means to an exposure time that reduces the influence of the flicker. A program for causing a computer to execute each step of the control method according to claim 14. A computer-readable storage medium storing a program for causing a computer to execute each step of the control method according to claim 14.
