Description

The present invention relates to an imaging device, a control method, a program, and a storage medium executed by the imaging device.

There is a so-called "selfie" or "selfie" shooting technique in which a user (photographer) of a digital camera or a video camera points a lens at himself / herself to shoot. Further, in "selfie" (or "selfie"), placing the image pickup device on a support such as the ground or a tripod and taking a picture at a place away from the user is called "selfie".

It has been very troublesome for the user to set a desired composition (imaging direction and zoom magnification) when performing such "placement shooting". That is, the user needs to approach the image pickup device in order to adjust the composition, but then the user himself / herself moves from the original position in the image pickup range, and the desired composition including the user himself / herself cannot be confirmed. There was a problem.

Patent Document 1 discloses a technique of an operation control device for an imaging device. This operation control device includes a communication means for transmitting and receiving data, a display means for displaying an captured visual field image, and a detection means for detecting its own direction and / or posture. In addition, this operation control device instructs the control means for synchronously driving the orientation and / or attitude of the imaging device via the communication means based on the detected orientation and / or attitude information, and the imaging of the imaging device. It is provided with an imaging instruction means for performing. Then, this operation control device enables the photographer to easily adjust the captured field image of the imaging device to his / her intended composition by remotely controlling the imaging device.

Patent Document 2 discloses a camera technique. According to this technique, when the user sets the "requested shooting mode" and adjusts the zoom and composition for shooting, the posture data is acquired from the posture detection sensor and stored. When the user hands the camera to the person who takes the picture and asks for the picture, the camera compares the posture of the camera at that time with the stored posture data and displays a guide for holding the posture in the same posture as the posture data.

Patent Document 3 discloses an application service called "Sekai Camera (registered trademark)" as a background technology. "Sekai Camera (registered trademark)" changes the display position and size of images and videos captured so far based on the posture of the image pickup device, and superimposes them on the actual scene captured by the image pickup device. Is displayed.

In the technique disclosed in Patent Document 1, it is necessary that the image pickup apparatus has a configuration for synchronously driving the orientation and the posture. In addition, the image pickup device needs to have a configuration for transmitting the captured image so that the user can check the captured image even at a place away from the image pickup device.

The technique disclosed in Patent Document 2 is for reproducing a composition similar to the composition taken in the "requested shooting mode", but is a technique for facilitating the composition adjustment of the user in the "requested shooting mode". Is not disclosed. Therefore, the technique of Patent Document 2 cannot facilitate composition adjustment for "placement shooting".

The "Sekai Camera (registered trademark)" disclosed as a background technique in Patent Document 3 also does not facilitate composition adjustment for "placement shooting".

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The technical scope of the present invention is determined by the scope of claims, and is not limited by the following individual embodiments. Also, not all combinations of features described in the embodiments are essential to the present invention.

[First Embodiment]
In the first embodiment, a configuration for changing the display position or display angle of the review image based on the posture of the imaging device will be described. Specifically, when the user installs the imaging device on a tripod and shoots toward the user himself / herself, the user first shoots for composition adjustment. When the user gives an instruction of "composition adjustment (review reproduction)" during shooting, the imaging device finishes shooting for composition adjustment and automatically displays the shot image (review image). The operation of displaying the image shot immediately before without shifting to the playback mode after shooting is called "review display" or "review playback". If the posture of the image pickup device is changed by the user changing the angle of the tripod head during the review display, the image pickup device changes the display position or display angle of the review image based on the posture. In the present embodiment, the review display is automatically performed after the end of shooting, but the review display may be performed when the user gives an instruction to start the review display after the end of shooting. In any case, unlike the normal playback display, the image displayed in the review display (the image taken immediately before) is not switched to another image and displayed.

FIG. 1 is a block diagram showing a configuration of an image pickup apparatus 100 according to a first embodiment. In FIG. 1, 101 is a fixed first fixed lens group, 102 is a zoom lens that performs variable magnification, 103 is an aperture, and 104 is a fixed second fixed lens group. Reference numeral 105 denotes a focus lens having both a focus adjustment function and a so-called competition function for correcting the movement of the focal plane due to zooming. Reference numeral 106 denotes an image pickup device such as a CMOS sensor or a CCD sensor.

Reference numeral 107 denotes a camera signal processing unit, and reference numeral 108 denotes a display unit having a function of displaying an image (video) signal. The camera signal processing unit 107 converts an image (video) signal from the image sensor 106 into a signal S3 corresponding to the display unit 108 and the recording unit 109 described later. The display unit 108 can also be used as a touch display by integrally configuring a touch panel that outputs coordinate information according to the contacted position. Then, the user can touch the GUI (Graphical User Interface) such as the "composition adjustment shooting (review shooting)" button and the "normal shooting" button displayed on the touch display. As a result, the user can instruct the camera microcomputer 114, which will be described later, to perform "composition adjustment shooting (review shooting)" or "normal shooting". Reference numeral 109 denotes a recording unit, which records the signal of the captured image on the recording medium in response to the instruction of "composition adjustment shooting (review shooting)" or "normal shooting" by the user. As the recording medium, a semiconductor memory, a magneto-optical disk, a magnetic tape, or the like is generally used. Reference numeral 110 is a zoom drive unit for driving the zoom lens 102, and reference numeral 111 denotes a focus drive unit for driving the focus lens 105. The zoom drive unit 110 and the focus drive unit 111 each include a motor and a driver unit (not shown).

Reference numeral 114 denotes a camera microcomputer, which controls the zoom drive unit 110 and the focus drive unit 111. Further, the camera microcomputer 114 controls the zoom switch 115, which is an operating member for the zoom lens 102, which will be described later, and controls the output signal of the camera signal processing unit 107. Further, the camera microcomputer 114 calculates the target positions of the zoom lens 102 and the focus lens 105 from the optimized operation state, and compares them with the positions detected by the lens position detection units 112 and 113, which will be described later. Based on the comparison result, the camera microcomputer 114 controls the zoom drive unit 110 and the focus drive unit 111 to drive the zoom lens 102 and the focus lens 105.

Reference numeral 112 denotes a lens position detection unit that detects the position of the zoom lens 102, and 113 is a lens position detection unit that detects the position of the focus lens 105. These lens position detection units 112 and 113 include a photo sensor (not shown) and a light-shielding plate. The photo sensor is composed of a light emitting unit and a light receiving unit and is fixed to the lens barrel, and the light shielding plate is fixed to the zoom lens 102 and the focus lens 105, respectively. Then, when the zoom lens 102 and the focus lens 105 move in the direction parallel to the optical axis, the light-shielding plate moves integrally with the zoom lens 102 and the focus lens 105. When the light-shielding plate blocks the optical path between the light emitting portion and the light receiving portion of the photo sensor, the output signal of the light receiving portion becomes a low level, and when it does not block, it becomes a high level. Therefore, it is possible to detect whether or not the zoom lens 102 and the focus lens 105 are present at the reference position with the position where the output signal of the light receiving unit changes as the reference position. The camera microcomputer 114 can recognize the position of each lens based on the reference position, the lens moving speed, the lens moving direction, and the like.

Further, the camera microcomputer 114 is connected to a zoom switch 115 for moving the zoom lens 102 in the wide-angle (hereinafter, also referred to as “wide”) direction and the telephoto (hereinafter, also referred to as “tele”) direction. The zoom switch 115 is configured such that the voltage changes according to the pressing amount thereof. The camera microcomputer 114 detects the voltage change when the zoom switch 115 is operated, and determines at what speed of the variable speed zoom the zoom lens 102 is driven according to the voltage.

The built-in memory 118 is a non-volatile memory in which various settings such as a program and a display language for operating the camera microcomputer 114 are recorded. The RAM 119 is a volatile memory used as a work area when the camera microcomputer 114 executes a program.

The posture sensor 122 (posture detecting means) has functions such as acceleration measurement, geomagnetic measurement, and gyro measurement, and detects a posture (toward the camera) with respect to a reference direction (for example, the direction of the earth's axis). When the image pickup device 100 has a grounding portion whose angle can be changed or a connecting portion to a support such as a tripod, the attitude sensor 122 has a posture (camera) based on the grounding angle of the grounding portion and the connecting angle of the connecting portion. It may be configured to detect the orientation).

The camera microcomputer 114 has table data in the internal memory having a relationship between the position of the focus lens 105 and the distance to the subject in focus. Then, the camera microcomputer 114 calculates the display position, display angle, and display size of the review image from the detected posture (camera orientation) and zoom position while referring to these data tables on the internal program, and the position / position. It is output as an angle / magnitude signal S1.

Reference numeral 117 denotes a graphics generation unit, which moves, rotates, and resizes the review image based on the position / angle / size signal S1 and supplies it to the signal synthesis processing unit 116 described later. Reference numeral 116 denotes a signal synthesis processing unit, which is a so-called “missing” when the review image signal S2 after movement / rotation / resizing output from the graphics generation unit 117 and the review image are moved / rotated / resized. Combine with the background image signal of the "free area". The background image signal indicates, for example, black one-color graphics. The signal synthesis processing unit 116 outputs the composite video signal S4 obtained by synthesis. As a result, the review image is displayed on the display unit 108.

The built-in clock 123 measures the time and also measures the timer from a predetermined time point.

2A to 2C are flowcharts showing a flow of processing executed by the image pickup apparatus 100 according to the first embodiment. Unless otherwise specified, the processing of this flowchart is realized by the camera microcomputer 114 expanding the program recorded in the built-in memory 118 into the RAM 119 (system memory) and executing the program. When the power is turned on by the user, the processing of this flowchart starts.

In S201, the camera microcomputer 114 starts imaging. In S202, the camera microcomputer 114 displays the captured image (live view image) on the display unit 108. In S203, the camera microcomputer 114 displays a GUI (Graphical User Interface) including a "composition adjustment shooting (review shooting)" button and a "normal shooting" button on the display unit 108. A display example of the display unit 108 at this time is shown in FIG. 3A (a). As shown in FIG. 3A (a), the display unit 108 displays a GUI including a “composition adjustment shooting” button 301 and a “normal shooting” button 302 together with the captured image.

In S204, the camera microcomputer 114 determines whether or not the user has instructed "composition adjustment shooting (review shooting)". When "composition adjustment shooting (review shooting)" is instructed, the process proceeds to S205, and if not, the camera microcomputer 114 repeats the determination of S204. If "composition adjustment shooting (review shooting)" is not instructed, it is determined whether or not "normal shooting" is instructed, and if instructed, normal shooting is performed. The description is omitted.

In S205, the camera microcomputer 114 controls the recording unit 109 to start shooting (recording) the image being captured. The recording in S205 is a recording of a moving image or a recording of a plurality of still images at predetermined time intervals. The recording destination of the image data here is, for example, a recording medium connected to the recording unit 109, the built-in memory 118, the RAM 119, or the like.

In S206, the camera microcomputer 114 acquires the time T1 at which the recording of the captured image is started from the built-in clock 123. In S207, the camera microcomputer 114 records the time T1 in association with the video data. In S208, the camera microcomputer 114 displays the GUI including the "composition adjustment (review reproduction)" button on the display unit 108. The shooting situation at this time is shown in FIG. 3A (b), and a display example of the display unit 108 is shown in FIG. 3A (c). As shown in FIG. 3A (b), the user 303 “selfie” his / her dance by taking a picture for composition adjustment. Further, as shown in FIG. 3A (c), the display unit 108 displays the image captured and the GUI including the “composition adjustment” button 304.

In S209, the camera microcomputer 114 determines whether or not "composition adjustment (review reproduction)" has been instructed by the user. When "composition adjustment (review reproduction)" is instructed, the process proceeds to S210, and if not, the camera microcomputer 114 repeats the determination of S209.

In S210, the camera microcomputer 114 stops recording the image being captured. In S211 the camera microcomputer 114 calculates the recording time Δt of the recorded video (review image). In S212, the camera microcomputer 114 compares Δt with the predetermined time length Δt0. When Δt ≧ Δt0, the process proceeds to S213, and when Δt <Δt0, the process proceeds to S214.

In S213, the camera microcomputer 114 reproduces and displays the review image on the display unit 108 from the time before Δt0 of the time when the recording of the review image is stopped. That is, when the end of the composition adjustment shooting is the timing when a predetermined time or more has elapsed from the start of shooting, the display of the shot image starts from the portion corresponding to the time before the predetermined time from the end of shooting. In S214, the camera microcomputer 114 reproduces and displays the review image on the display unit 108 from the time when the recording of the review image is started. That is, when the end of the composition adjustment shooting does not elapse more than a predetermined time from the start of shooting, the camera microcomputer 114 starts displaying the shot image from the portion corresponding to the shooting start time in S215. The GUI including the "composition adjustment end" button is displayed on the display unit 108 (S215). That is, during the reproduction display of the review image, the "composition adjustment end" button is displayed.

In S216, the camera microcomputer 114 determines whether or not the change in the attitude of the device is detected by the attitude sensor 122. If a change in device attitude is detected, the process proceeds to S217, otherwise the process proceeds to S218.

In S217, the camera microcomputer 114 changes the display position or the display angle at which the review image is displayed on the display unit 108 based on the posture change. The method of changing the display position and the display angle will be described later.

In S218, the camera microcomputer 114 determines whether or not the user has instructed "composition adjustment end". If "composition adjustment end" is instructed, the process proceeds to S219, otherwise the process proceeds to S221.

In S219, the camera microcomputer 114 erases the data of the review image recorded in the recording medium, the built-in memory 118, or the RAM 119. In S220, the camera microcomputer 114 determines whether or not a predetermined termination condition (power off, etc.) is satisfied. If the predetermined termination condition is not satisfied, the process returns to S201. When the predetermined end condition is satisfied, the process of this flowchart ends.

In S221, the camera microcomputer 114 determines whether or not the review image has been reproduced to the end. If the review image is reproduced to the end, the process proceeds to S222, otherwise the process returns to S216. In S222, the camera microcomputer 114 reproduces and displays the review image again from the reproduction start position (see S212 to S214) of the review image.

When the user touches the "normal shooting" button 302 in FIG. 3A (a) (when a normal shooting instruction is received), the camera microcomputer 114 performs normal shooting. In this case, the camera microcomputer 114 shoots a still image, a moving image, or the like according to the shooting mode, and records the obtained image data on a recording medium connected to the recording unit 109. Further, the camera microcomputer 114 automatically displays the captured image by the normal shooting on the display unit 108 after the shooting is completed (review display of the normal shooting). During the review display of normal shooting, the camera microcomputer 114 does not perform control such as changing at least one of the display position and the display angle of the review image based on the device posture as in S217.

Further, as described in S219, the camera microcomputer 114 erases (deletes) the data of the review image at the end of the review display of the composition adjustment shooting. However, the camera microcomputer 114 does not erase (delete) the data of the review image at the end of the review display of the normal shooting.

The operation during the review display (particularly S217) will be described with reference to FIG. 3B. As shown in FIGS. 3B (a) and 3B (b), the user 303 touches the “composition adjustment” button 304 (FIG. 3A (c)), then moves to the position of the image pickup apparatus 100, and displays the display unit 108. While looking at the review image 305 displayed in, the posture of the image pickup apparatus 100 is changed. In FIG. 3B (b), 307 is a tripod head, 308 is a pan bar, and 309 is a user 303. Before the posture of the image pickup apparatus 100 changes, the review image 305 is displayed on the entire display area of the display unit 108.

When the posture of the imaging device 100 is changed from the original posture by the user 303 so as to face the upper right with respect to the imaging direction, the display state of the display unit 108 changes to the state shown in FIG. 3B (c). The display position of the review image 309 in FIG. 3B (c) is moved to the lower left as compared with the display position of the review image 305 in FIG. 3B (b), and as a result, the display position is right and the display area of the display unit 108. There is a free area 310 above. The display position of the review image 309 is the case where the user 303 moves again to the place where the user 303 was at the time of recording the review image (FIG. 3A (b)) and the image pickup apparatus 100 takes an image in the changed posture. It becomes the same as the display position of the user 303 in the image obtained in. That is, in the review image 305, the head of the user 303 protrudes from the imaging region. On the other hand, when the posture of the image pickup apparatus 100 is changed as shown in FIG. 3B (c) and the image is taken again in that posture, it is assumed that the user is again in the place where the user 303 was at the time of recording the review image 309. For example, the head of the user 303 is included in the imaging region. Further, since the review image 309 is displayed so that an empty area 310 is generated on the right and above the display area of the display unit 108, the user 303 is suitable for including his / her head in the imaging area. It becomes easy to adjust the device posture so as to be the device posture.

In the review image, even when the head of the user 303 is unsuitably separated from the upper side of the imaging range as a composition (in the case of so-called "heavenly space"), the user 303 similarly adjusts the device posture. Can be adjusted to. That is, in this case, the user 303 changes the posture of the image pickup apparatus 100 so as to face downward with respect to the original posture during the review display. Then, the image pickup apparatus 100 moves the display position of the review image on the display unit 108 (on the display means) upward. As a result, the head of the user 303 in the review image approaches the upper side of the display area. Therefore, the user 303 can adjust the posture of the device so that his / her head is in an appropriate position in the imaging region.

FIG. 4 is a diagram illustrating how to change the display position on the display unit 108 of the review image when the posture of the image pickup apparatus 100 changes during the review display. In FIG. 4A, the image pickup apparatus 100 images a subject at a vertical viewing angle Φ. When the distance to the subject is L, the image pickup range in the vertical direction at the distance of the subject is "2L · tan (Φ / 2)". That is, when the display unit 108 of the image pickup apparatus 100 is composed of pixels of horizontal X pixels and vertical Y pixels, "2L · tan (Φ / 2)" corresponds to Y pixels (see FIG. 4B). ..

When the posture of the image pickup apparatus 100 is changed so as to face upward by an angle φ, the image pickup range in the vertical direction at the distance of the subject moves upward by “2 L · tan (φ / 2)”. That is, the original imaging range is shifted downward by "Y · (tan (φ / 2) / tan (Φ / 2))" pixels on the display unit 108 (see FIG. 4C).

Based on this point, consider a case where the vertical viewing angle of the imaging device 100 is Φ and the vertical posture of the imaging device 100 is changed by φ upward or downward. In this case, if the display of the review image is moved downward or upward by "Y · (tan (φ / 2) / tan (Φ / 2))" pixels on the display unit 108, the image is taken in the changed posture. It is possible to display the review image at the position corresponding to the composition.

Similarly, when the horizontal viewing angle of the imaging device 100 is Θ, consider a case where the horizontal posture of the imaging device 100 is changed by θ to the right or left. In this case, if the display of the review image is moved to the left or right by "X · (tan (θ / 2) / tan (Θ / 2))" pixels on the display unit 108, the image is taken in the changed posture. It is possible to display the review image at the position corresponding to the composition.

Further, consider the case where the rotation angle of the image pickup apparatus 100 with respect to the image pickup optical axis is changed during the review display. In this case, the image pickup apparatus 100 rotates the display of the review image on the display unit 108 in the opposite direction by the same angle while keeping the center position as it is. That is, in this case, a triangular empty area is generated at the four corners of the rectangle of the display unit 108. This makes it possible to display the review image at an angle corresponding to the composition when the image is taken at an angle with respect to the changed optical axis.

When the posture of the image pickup apparatus 100 changes during the review display, a single color such as black or white can be displayed in the empty area when the display position on the review image display unit 108 is changed. Alternatively, the image (so-called “through image” or “live view image”) captured in the (changed) posture may be displayed in the free area. In this case, subjects other than the user in the review image (such as a subject in the background) should be displayed so as to be continuous with the review image. For example, when the user's head protrudes from the imaging area during the composition adjustment shooting, the user's head is not recorded in the review image, so that the user's head is not displayed even during the review display. However, when the posture of the imaging device 100 is changed so that the user's head is within the imaging range, the background subject at the position corresponding to the user's head is on the display unit 108 when the display position of the review image is moved. Will be displayed in the free space of. That is, the user can change the posture of the imaging device 100 while checking the background subject, and adjust the composition so that his / her head is included in the imaging region. When displaying the image captured in the free area, the image pickup apparatus 100 may superimpose the boundary line so that the boundary between the review image and the free area becomes clear.

As described above, according to the first embodiment, in the review display of the captured image, the imaging device 100 has at least one of the display position and the display angle on the display unit 108 of the captured image based on the device posture. To change. This makes it possible for the user to easily adjust the composition for so-called "placement shooting" without the need for remote control of the image pickup apparatus 100.

[Second Embodiment]
In the second embodiment, a configuration will be described in which the display size of the review image is changed according to the zoom operation of the image pickup apparatus, and at the next shooting, shooting is performed at a zoom magnification corresponding to the zoom operation during the review display. .. In the present embodiment, the basic configuration and operation of the image pickup apparatus 100 are the same as those in the first embodiment (see FIGS. 1 and 2A to 2C). Hereinafter, the points different from the first embodiment will be mainly described.

In the present embodiment, the image pickup apparatus 100 executes the process shown in FIG. 5A following the process of S215 in FIG. 2B. The process of FIG. 5 (a) replaces the process of S216 to S217 of FIG. 2 (c). However, the image pickup apparatus 100 may also execute the processes S216 to S217 of FIG. 2 (c) in addition to the process of FIG. 5 (a). Unless otherwise specified, the processing of this flowchart is realized by the camera microcomputer 114 expanding the program recorded in the built-in memory 118 into the RAM 119 (system memory) and executing the program.

In S516, the camera microcomputer 114 determines whether or not the user has performed a zoom operation using the zoom switch 115. If the zoom operation is performed, the process proceeds to S517, otherwise the process proceeds to S218.

In S517, the camera microcomputer 114 changes the display size for displaying the review image on the display unit 108 based on the zoom operation amount. The details of the display size change will be described with reference to FIGS. 3B (a), 3B (b), 5 (b), and 6.

As shown in FIGS. 3B (a) and 3B (b), the user 303 operates the zoom switch 115 while looking at the review image 305 displayed on the display unit 108. When the zoom switch 115 is operated in the direction of lowering the zoom magnification (the direction of capturing a wider viewing angle) (when the operation is performed in the wide-angle direction), the display state of the display unit 108 is shown in FIG. 5 (b). It changes to the state shown in. The display size of the review image 509 of FIG. 5B is reduced as compared with that before the zoom operation, and as a result, an empty area 510 is generated at the periphery of the display area of the display unit 108. The display size of the review image 509 is the same size as the portion corresponding to the review image 509 in the image obtained when the image is taken by the viewing angle (zoom magnification) after the zoom operation. That is, in the review image 509, the head of the user 303 protrudes from the imaging region. On the other hand, when the viewing angle of the imaging device 100 was changed as shown in FIG. 5B and the image was taken again at that viewing angle, the user was again at the place where the user 303 was at the time of recording the review image 309. If so, the head of the user 303 will be included in the imaging region. Further, since the review image 509 is displayed so that an empty area 510 is generated at the peripheral edge of the display area of the display unit 108, the user 303 has an appropriate viewing angle so that his / her head is included in the imaging area. Therefore, it becomes easy to adjust the zoom magnification.

The camera microcomputer 114 (shooting control means) controls the zoom magnification corresponding to the zoom operation performed during the review display of the shot image obtained by the composition adjustment shooting so as to be reflected in the next shooting. .. Further, the camera microcomputer 114 can also perform normal shooting as in the first embodiment. However, even if the zoom operation is performed during the review display of the normal shooting, the camera microcomputer 114 does not reflect this zoom operation in the zoom magnification of the next shooting.

FIG. 6 is a diagram illustrating how to change the display size on the display unit 108 of the review image when the zoom operation is performed during the review display. In FIG. 6A, the image pickup apparatus 100 images a subject at a vertical viewing angle Φ. When the distance to the subject is L, the image pickup range in the vertical direction at the distance of the subject is "2L · tan (Φ / 2)".

When the vertical viewing angle is changed to Φ', the image pickup range in the vertical direction at the distance of the subject becomes "2L · tan (Φ' / 2)". That is, the original imaging range is resized "(tan (Φ / 2) / tan (Φ' / 2))" times on the display unit 108 (FIGS. 6 (b) and 6 (FIG. 6) and 6 (FIG. 6). c) See).

Based on this point, consider a case where a zoom operation is performed and the vertical viewing angle is changed from Φ to Φ'during the review display of the captured image obtained by photographing at the vertical viewing angle Φ. In this case, if the display of the review image is resized to "(tan (Φ / 2) / tan (Φ'/2))" times as it is at the center position on the display unit 108, the zoom magnification after the change will be used. It is possible to display the review image at the position and size corresponding to the composition when the image is taken. That is, the user can operate the zoom switch 115 of the imaging device 100 while viewing the review image captured by himself / herself during the review display to adjust the zoom magnification so that he / she is imaged in an appropriate size. It will be possible.

As described above, according to the second embodiment, in the review display of the captured image, the imaging device 100 changes the display size on the display unit 108 of the captured image according to the zoom operation. In addition, the image pickup apparatus 100 controls the next time of shooting so as to perform shooting at a zoom magnification corresponding to the zoom operation. This makes it possible for the user to easily adjust the composition for so-called "placement shooting" without the need for remote control of the image pickup apparatus 100.

The above-mentioned various controls described as being performed by the camera microcomputer 114 may be performed by one hardware, or the entire device may be controlled by sharing the processing among a plurality of hardware.
