Description

An image pickup apparatus according to the present invention includes a first image pickup unit that performs exposure of the image pickup unit at a predetermined timing to reduce the influence of ambient environment flicker by an image pickup unit, a photometric unit that measures a subject, and a user. or executing the control, determining a setting unit capable of setting whether to perform a different second imaging control, the exposure control value using the photometric value based on the output of the previous SL metering means with the first imaging control a determining means for, wherein the determining means is executing the exposure control value when it is set to perform the first imaging control by said setting means, said second imaging control The exposure control value when set is determined using a different photometric value.

Claims (10)

Imaging means;
A metering means for metering the subject;
The user performs the first imaging control for executing the exposure of the imaging means at a predetermined timing for reducing the influence of the ambient ambient light flicker, or a second imaging control different from the first imaging control. Setting means capable of setting whether to execute,
Anda determining means for determining an exposure control value using the photometric value based on the output of the previous SL photometry means,
Said determining means, an exposure control value in the case of performing the exposure control value when it is set to perform the first imaging control by said setting means, said second imaging control is set Is determined using different photometric values. It further comprises detection means for detecting the presence or absence of flicker of ambient ambient light using a photometric value based on the output of the photometric means,
The determination unit is configured to obtain a photometric value corresponding to the predetermined timing when the setting unit is set to execute the first imaging control and flicker is detected by the detection unit. The imaging apparatus according to claim 1, wherein an exposure control value is determined using the imaging apparatus. Control means for switching whether to execute the first imaging control or the second imaging control, and the control means has an exposure time corresponding to the exposure control value determined by the determining means. , wherein when the ratio for the period of the detected flicker by the detecting means is smaller than a predetermined value, have rows the first imaging control, the exposure time corresponding to the exposure control value determined by said determining means, said detecting The imaging apparatus according to claim 2, wherein the second imaging control is performed when the ratio of the flicker period detected by the means is a predetermined value or more . The detection means causes the photometry means to perform accumulation for a predetermined time shorter than one period of flicker light amount change a plurality of times, and detects the presence or absence of flicker based on a change in the photometric value obtained from the plurality of accumulations. The imaging apparatus according to claim 2 or 3 , wherein The determining means is an average of the photometric values based on the plurality of accumulations when the setting means is set to execute the first imaging control and no flicker is detected by the detecting means. The imaging apparatus according to claim 4, wherein the exposure control value is determined using the value. Wherein the predetermined is timing, an imaging apparatus according to claim 5, out of the light metering value based on the accumulation of the plurality of times, flicker is characterized in that the timing at which the peak. Display means for displaying the exposure control value is further provided, and the display means switches the exposure control value to be displayed between when the first imaging control is performed and when the second imaging control is performed. The image pickup apparatus according to claim 1, wherein the image pickup apparatus is an image pickup apparatus. A method for controlling an imaging apparatus comprising an imaging means and a photometric means for photometry of a subject,
The user performs the first imaging control for executing the exposure of the imaging means at a predetermined timing for reducing the influence of the ambient ambient light flicker, or a second imaging control different from the first imaging control. A setting process that can set whether to execute ,
Determining an exposure control value using a photometric value based on the output of the photometric means,
The determining step includes an exposure control value when execution of the first imaging control is set in the setting step, and an exposure control value when execution of the second imaging control is set. Is determined by using different photometric values. The program for making a computer perform each process of the control method of Claim 8 . A computer-readable storage medium storing a program for causing a computer to execute each step of the control method according to claim 8 .
