Image pickup apparatus, control method, control apparatus, and storage medium
An image pickup apparatus includes an image sensor configured to receive light and accumulate charges, a vibration generator configured to generate vibration, an image sensor control unit configured to cause the image sensor to perform an electronic front curtain operation to start accumulating the charges, and an electronic rear curtain operation to finish accumulating the charges, and a vibration control unit configured to control the vibration generator. The vibration control unit causes the vibration generator to generate first vibration before accumulating the charges is started and second vibration after the accumulating the charges are finished.
1. An image pickup apparatus comprising:
an image sensor configured to receive light and accumulate charges;
a vibration generator configured to generate vibration;
at least one processor; and
a memory coupled to the at least one processor,
wherein the memory has instructions that, when executed by the processor, configure the processor to operate as:
an image sensor control unit configured to cause the image sensor to perform an electronic front curtain operation to start accumulating the charges, and to perform an electronic rear curtain operation to finish accumulating the charges; and
a vibration control unit configured to control the vibration generator,
wherein the vibration control unit causes the vibration generator to generate first vibration before accumulating the charges is started and second vibration after the accumulating the charges are finished.
2. The image pickup apparatus according to claim 1 , wherein in a case where a charge accumulating period is longer than a predetermined period, the vibration control unit causes the vibration generator to generate the first vibration and the second vibration, and
wherein in a case where the charge accumulating period is shorter than the predetermined period, the vibration control unit causes the vibration generator to generate third vibration instead of the first and second vibrations.
3. The image pickup apparatus according to claim 2 , wherein the vibration control unit causes the vibration generator to generate the third vibration during readout of accumulated charges.
4. The image pickup apparatus according to claim 2 , wherein the third vibration is vibration in which at least one of acceleration and amplitude is larger than that of each of the first vibration and the second vibration.
5. The image pickup apparatus according to claim 2 , wherein the third vibration is vibration that is different in at least one of frequency and duration from at least one of the first vibration and the second vibration.
6. The image pickup apparatus according to claim 2 , wherein the vibration control unit changes the predetermined period according to selection by a user.
7. The image pickup apparatus according to claim 2 , wherein the vibration control unit changes the predetermined period according to an imaging mode.
8. The image pickup apparatus according to claim 1 , wherein the second vibration is vibration in which at least one of acceleration and amplitude is larger than that of the first vibration.
9. The image pickup apparatus according to claim 1 , wherein the second vibration has a duration longer than that of the first vibration.
10. A control method for an image pickup apparatus that includes an image sensor configured to receive light and accumulate charges, and a vibration generator configured to generate vibration, the control method comprising the steps of:
causing the image sensor to perform an electronic front curtain operation to start accumulating the charges, and to perform an electronic rear curtain operation to finish accumulating the charges; and
causing the vibration generator to generate first vibration before accumulating the charges is started and second vibration after the accumulating the charges are finished.
11. A non-transitory computer-readable storage medium storing a program that causes a computer to execute the control method according to claim 10 .
12. A control apparatus for an image pickup apparatus that includes an image sensor configured to perform an electronic front curtain operation to start accumulating the charges, and an electronic rear curtain operation to finish accumulating the charges, and a vibration generator configured to generate vibration, the control apparatus comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the memory has instructions that, when executed by the processor, configure the processor to operate as:
a vibration control unit configured to control the vibration generator,
wherein the vibration control unit causes the vibration generator to generate first vibration before the image sensor starts accumulating the charges and second vibration after the image sensor finishes accumulating the charges.
13. The control apparatus according to claim 12 , wherein the vibration control unit causes the vibration generator to generate the second vibration after readout of accumulated charges is finished.
14. The control apparatus according to claim 12 , wherein the vibration control unit causes the vibration generator to generate the first vibration so that the first vibration stops before the image sensor starts accumulating the charges.
