Description

The present invention relates to an imaging device and a photographing lens capable of re-imaging content.

In recent years, video distribution services using communication networks such as the Internet have become widespread, and users can upload captured video contents to the video distribution service. When shooting video content, the user may reshoot the video multiple times. In this case, the number of shot video contents increases, and the management of the video contents becomes complicated. As a related technique, Patent Document 1 proposes a technique for displaying content objects side by side in a three-dimensional space. In the technique of Patent Document 1, the x-axis is divided into a predetermined time range, and the y-axis is divided into different timelines according to the combination of tag information. Further, a plurality of content objects included in the same predetermined time range and having the same tag information are displayed side by side on the z-axis.

Japanese Unexamined Patent Publication No. 2011-071813

When the video content is re-shooted, the shooting conditions may change from the shooting conditions when the shot video content to be re-shot is shot. For example, when the moving image content of the same scene is re-shooted, the moving image content may be re-shot with a shooting lens different from the shooting lens at which the shot moving image content was shot. In this case, there arises a problem that the re-shooting of the moving image content cannot be performed properly. Although the technique of Patent Document 1 displays a plurality of content objects side by side on the z-axis, it does not solve the above problem.

An object of the present invention is to provide an imaging device and a photographing lens capable of suppressing the re-imaging of contents from being performed properly.

In order to achieve the above object, the imaging device of the present invention has a recording unit that records a plurality of photographed contents and shooting conditions when each photographed content is photographed, and any of the plurality of photographed contents. The re-shooting instruction means that can give a re-shooting instruction in the selected state and the shooting conditions when the re-shooting instruction is given to the re-shooting instruction means shoot the selected shot content. It is characterized in that it is provided with a control means for controlling to output a warning when the shooting conditions are different from those at the time of shooting.

According to the present invention, it is possible to prevent the content from being re-photographed properly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the configurations described in the following embodiments are merely examples, and the scope of the present invention is not limited by the configurations described in the respective embodiments.

<First Embodiment>
Hereinafter, the first embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of the imaging device. FIG. 1A is a perspective view of the image pickup apparatus 10 with the lens unit 50 removed, as viewed from the rear side. FIG. 1B is a perspective view of the image pickup apparatus 10 with the lens unit 50 removed from the side of the first operation unit 301.

The image pickup apparatus 10 includes a movable portion 20, a fixed portion 30, a hinge unit 40, and a lens unit 50. The movable portion 20 and the fixed portion 30 are relatively rotatably connected by a hinge unit 40. The lens unit 50 is configured to be removable from the movable portion 20. Therefore, the lens unit 50 as a photographing lens can be attached to and detached from the imaging device 10. A bayonet-type mounting structure is adopted for the lens unit 50 and the movable portion 20. A bayonet claw portion 507 is formed on the lens unit 50, and a lens mount 211 is formed on the movable portion 20. The lens mount 211 corresponds to the lens mounting means. When attaching the lens unit 50 to the movable portion 20, the user first aligns the protruding portion of the bayonet claw portion 507 with respect to the notch formed inside the lens mount 211. Then, the user inserts the lens unit 50 into the movable portion 20 and rotates the lens unit 50 around the optical axis. As a result, the lens unit 50 is attached to the movable portion 20.

A movable pin 204a (FIG. 3), which is a part of the lens rotation restricting portion 204, protrudes from the lens mount 211. By engaging the movable pin 204a with the recess 508 on the lens unit 50 side, the lens rotation regulating portion 204 regulates the movable portion 20 from rotating and coming off from the state in which the lens unit 50 is mounted. .. When removing the lens unit 50 from the movable portion 20, the user operates the second operating portion 202. By operating the second operating portion 202, the movable pin 204a retracts inward, and the engagement between the bayonet claw portion 507 of the lens unit 50 and the lens mount 211 is released. As a result, the lens unit 50 can be removed. Details of the internal structure of the movable portion 20 will be described later. When the lens unit 50 is attached to the movable portion 20, as shown in FIG. 2, the interface portion 205 of the movable portion 20 and the interface portion 506 of the lens unit 50 are electrically connected. In FIG. 2, the interface unit is referred to as "IF". With the interface unit 205 and the interface unit 506 electrically connected, the lens unit 50 and the movable unit 20 can communicate with each other.

The movable portion 20 is held by the hinge unit 40. The hinge unit 40 is a biaxial hinge mainly composed of a tilt rotation hinge 401 and a pan rotation hinge 402. The tilt rotation hinge 401 rotatably supports the movable portion 20 with respect to the rotation axis T. Further, the pan rotation hinge 402 rotatably supports the fixing portion 30 with respect to the rotation shaft P. Therefore, the user can shift the movable portion 20 and the lens unit 50 to various postures with respect to the fixed portion 30 by appropriately operating the tilt rotation hinge 401 and the pan rotation hinge 402. Further, the hinge unit 40 has a certain amount of holding force in a state where the tilt rotation hinge 401 and the pan rotation hinge 402 are stopped. The holding force is set to be higher than the static torque at which the hinge unit 40 maintains the stopped posture while receiving the weight of the lens unit 50 and the movable portion 20. Therefore, in the predetermined position, when the user points the lens unit 50 at the subject and stops the rotation of the hinge unit 40, the lens unit 50 and the movable portion 20 can continue to maintain the same posture. .. Further, the movable portion 20 has an accessory shoe 208. The accessory shoe 208 is a portion to which an external accessory can be attached to the image pickup device 10. Accessories such as a video light and an external microphone can be attached to the accessory shoe 208.

The fixing unit 30 has a display unit 303. The display unit 303 is composed of an LCD (Liquid Crystal Display), an organic EL (Electro-luminescence) display, or the like. The display unit 303 is a display unit for displaying a captured image, a screen for setting shooting conditions, and the like. Hereinafter, the display unit 303 will be described as being a touch panel display. However, the image pickup apparatus 10 may be provided with an input function separate from the display unit 303. Further, the fixing portion 30 has a grip portion 304. The grip portion 304 is formed at the end of the fixing portion 30. The surface of the grip portion 304 is made of an elastic material, and for example, ethylene propylene diene rubber (EPDM), silicon rubber, or the like is adopted.

The user can freely rotate the lens unit 50 and the movable portion 20 with the other hand while holding the grip portion 304 with one of both hands. This makes it possible to shoot from various angles. Further, the first operation unit 301 is arranged at a position where the user can operate the grip unit 304 while gripping it. The first operation unit 301 includes a first button 301a, a second button 301b, and a touch pad 301c. The first button 301a is a member for giving a shooting instruction (take instruction). The second button 301b is a member for giving a re-shooting instruction (retake instruction). The touch pad 301c is a member for performing a slide operation. The touch pad 301c corresponds to the selection means.

FIG. 2 is a block diagram showing an internal configuration of the image pickup apparatus 10. First, the lens unit 50 will be described. The photographing optical system 501 includes a plurality of lenses, a holder for holding the plurality of lenses, a zoom mechanism, a focus mechanism, a shake correction mechanism, and the like. Further, the lens unit 50 has an aperture unit 502. For the diaphragm unit 502, for example, a glow diaphragm unit that changes the size of the opening formed around the optical axis by driving a plurality of thin light-shielding sheets is adopted. The lens drive unit 503 includes a zoom mechanism, a focus mechanism, a shake correction mechanism, and an actuator. The actuator is used to drive the aperture unit 502 and the like. The actuators applied to each of these mechanisms are appropriately selected in consideration of the thrust and speed required for driving, the stroke, the stopping accuracy, the power consumption, the manufacturing cost, and the like. For example, as the above actuator, a DC motor, a stepping motor, a USM (Ultrasonic Motor), or the like is adopted.

The lens control unit 504 includes a motor driver IC and drives and controls various actuators of the lens drive unit 503. By electrically connecting the lens unit 50 and the movable unit 20 by the interface unit 506 and the interface unit 205, the lens control unit 504 and the central control unit 206 described later can communicate with each other. The lens unit 50 further includes a runout detection unit 505. The runout detection unit 505 is composed of a gyro sensor, an acceleration sensor, and the like. The input information from the runout detection unit 505 is transmitted to the lens control unit 504, and is transmitted to the central control unit 206 as an analog signal or digital data via the interface unit 506 and the interface unit 205.

Next, the internal configuration of the movable portion 20 will be described. The movable unit 20 has an imaging unit 201. The image pickup unit 201 includes a photoelectric conversion element such as a CCD (Charge Coupled Device) sensor and a CMOS (Complementary MOS) sensor, and a low-pass filter. For example, a low-pass filter is made of quartz and is subjected to infrared cut processing. The low-pass filter prevents infrared rays from entering and prevents color moire and the like from occurring. The central control unit 206 includes a CPU (Central Processing Unit) that controls the entire image pickup device 10. The central control unit 206 corresponds to the control means. The control of each embodiment is realized by the CPU executing a program of a predetermined memory. The central control unit 206 includes a display control unit 207 that controls the display of various contents and information. The display control unit 207 corresponds to the display control means. The display control unit 207 may be provided separately from the central control unit 206. Hereinafter, in each embodiment, the content will be described as being moving image content. However, the content is not limited to video content. For example, the content may be content such as a still image or audio.

The electric signal input from the imaging unit 201 to the central control unit 206 is converted into a video signal and then appropriately processed into arbitrary video data (image data). Processing for video signals also includes electronic anti-vibration operation by image cropping and rotation processing. The central control unit 206 records the video data acquired by shooting and the shooting information when the video data is shot in the recording unit 210. The shooting information includes shooting conditions when the moving image content is shot. For example, the shooting conditions include the type and focal length of the lens unit 50, the focal length range, the usage status of accessories, and information on the orientation of the lens unit 50. The shooting conditions may include other conditions related to shooting. In addition, the shooting information may include other information (information such as shooting date and time, various settings, etc.). Further, other information may be recorded in the recording unit 210.

The second operation unit 202 is a member operated by the user when the lens unit 50 is removed from the movable unit 20. The second operation unit 202 can transition between a plurality of positions. The position detection unit 203 detects the position of the second operation unit 202. The position detection unit 203 detects the position of the second operation unit 202 by, for example, a transmissive photo interrupter whose output signal changes according to the amount of received light. The detection result detected by the position detection unit 203 is transmitted to the central control unit 206. Further, the lens rotation regulating unit 204 operates by operating the second operating unit 202. The movable pin 204a, which is a part of the lens rotation regulating unit 204, can reciprocate between a position protruding from the surface of the lens mount 211 and a position retracting from the surface of the lens mount 211.

Next, the internal configuration of the fixing portion 30 will be described. The fixing unit 30 has a first operating unit 301, a power supply unit 302, a display unit 303, and a gripping unit 304. The first operation unit 301 is arranged at a position where the user can operate the grip unit 304 with one hand. For the power supply unit 302, for example, a battery pack equipped with an alkaline secondary battery, a lithium ion secondary battery, or the like is adopted. Further, the power supply unit 302 is electrically connected to the central control unit 206 via a wire harness or the like wired inside the hinge unit 40. Then, power is supplied to the system of the image pickup apparatus 10.

Next, the internal configuration of the hinge unit 40 will be described. The hinge unit 40 has a first angle detection unit 403 and a second angle detection unit 404. The first angle detection unit 403 and the second angle detection unit 404 are configured by a detection switch or the like that detects a rotation angle. The first angle detection unit 403 can detect the rotation of the tilt rotation hinge 401 described above. The second angle detection unit 404 can detect the rotation of the pan rotation hinge 402 described above. The first angle detection unit 403 and the second angle detection unit 404 can detect the rotation of the movable portion 20 with respect to the fixed portion 30 in the pan direction and the tilt direction. The input information from the first angle detection unit 403 and the second angle detection unit 404 is transmitted to the central control unit 206.

Next, the details of the internal structures of the movable portion 20 and the hinge unit 40 will be described. FIG. 3 is an exploded perspective view of the movable portion 20. The lens mount 211 is fixed to the base member 212 by screws 215a, 215b, 215c and 215d. The base member 212 has a metal die-cast component. For the metal die casting, for example, magnesium alloy die casting, aluminum alloy die casting, or the like is adopted. The base member 212 has a lens rotation regulating unit 204 and an interface unit 205.

The interface unit 205 has a plurality of contact pins, an urging member such as a coil spring, and a resin case containing these. A plurality of contact pins project from the opening of the resin case. The contact pin is an urging member (not shown) and is always urged from the back side. Further, the contact pin is configured to be slidable inward from the surface of the resin case. A flexible printed circuit board 214 is connected to the interface unit 205. Depending on the protruding position of the contact pin, the conductive pattern wired inside the flexible printed circuit board 214 and the contact pin are electrically conductive. When the contact pin is pushed inward from the surface of the resin case by a certain amount, the contact pin and the conductive pattern of the flexible printed circuit board 214 are electrically conductive.

The movable portion 20 further has a side cover 213. The accessory shoe 208 is fixed to the side cover 213 by two screws 216. The side cover 213 is fixed to the base member 212 by fastening the screws 217a and 217b from the screw holes formed in the accessory shoe 208 to the base member 212 through the relief holes of the side cover 213. Then, the imaging unit 201 is fixed to the base member 212 by screws 223a, 223b, and 223c. The imaging unit 201 includes a photoelectric conversion element, a low-pass filter, and the like. The imaging unit 201 has a hard package that is electrically connected to the photoelectric conversion element, a printed circuit board on which the hard package is mounted, various electronic components mounted on the printed circuit board, and a metal plate in which the hard package is previously adhered and fixed. For the rigid package, for example, a multilayer substrate having a ceramic base material is adopted. A conductor pattern is formed inside the rigid package. A part of the conductor pattern is connected to an electrode terminal exposed on the surface, and a part of the electrode terminal and the photoelectric conversion element are electrically connected by a method such as wire bonding. Further, the electrode terminals of the hard package are mounted on the printed circuit board together with various electronic components by a reflow soldering method or the like. The metal plate described above is a member for attaching the imaging unit 201 to the base member 212. After the hard package is aligned with the metal plate, the side surface of the hard package and the end face of the metal plate are adhesively fixed. As the adhesive used for adhesive fixing, for example, an ultraviolet curable resin that cures in response to light energy by irradiation with ultraviolet rays is adopted.

The imaging unit 201 and the base member 212 composed of the above parts are fixed by screws with coil springs 222a, 222b, and 222c sandwiched between them. Therefore, the imaging unit 201 is supported so as to be slightly displaceable in the optical axis direction with respect to the base member 212. When the tightening amount of the screws 223a, 223b, and 223c is adjusted, the inclination of the imaging surface of the imaging unit 201 with respect to the base member 212 is adjusted. When the adjustment work is completed, the metal plate and each screw are adhesively fixed in order to prevent the screws 223a, 223b, and 223c from loosening.

As described above, the hinge unit 40 is mainly composed of a tilt rotation hinge 401 and a pan rotation hinge 402. The tilt rotation hinge 401 has two arm portions 401a and 401b fixed to the movable portion 20. In FIG. 3, the arm portion 401b is not shown. A holder 218a is rotatably supported on one of the arm portions 401a around the rotation axis T with respect to the arm portion 401a. A holder 218b is rotatably supported on the other arm portion 401b around the rotation axis T with respect to the arm portion 401b. The inside of the arm portion 401b that holds the holder 218b has a hollow structure. A harness 405 is inserted through the hollow structure and wired inside the pan rotation hinge 402. The harness 405 is further wired from the inside of the pan rotation hinge 402 to the inside of the fixed portion 30, and is electrically connected to the first operation unit 301, the power supply unit 302, the display unit 303, and the like. Screw fastening holes are formed in the holders 218a and 218b, respectively. The holder 218a is fixed to the base member 212 by the screws 220a and 220b. Further, the holder 218b is fixed to the base member 212 by the screws 221a and 221b.

A plurality of screw fastening holes are formed in the chassis 224. The chassis 224 is fixed to the side cover 213 by screws 225a and 225b. Then, the printed circuit board 226 is screwed and fixed to the chassis 224 by screws 228a, 228b, and 228c. Various electronic components are mounted on the printed circuit board 226 by a reflow soldering method or the like. The printed circuit board 226 includes a central control unit 206, a display control unit 207, a recording unit 210, and the like. Further, a plurality of connectors are mounted on the printed circuit board 226. The flexible printed circuit board 214 and the harness 405 are electrically connected to the printed circuit board 226. When one end of the flexible printed circuit board 227 is connected to the printed circuit board 226 and the other end is connected to the printed circuit board mounted on the image pickup unit 201, the image pickup unit 201 and the printed circuit board 226 are electrically connected. ..

The back cover 229 has a second operating unit 202. The flexible printed circuit board 230 extends from the second operation unit 202. The side cover 213 and the back cover 229 engage with each other in a state where the flexible printed circuit board 230 is connected to the connector mounted on the printed circuit board 226. The back cover 229 is formed with engaging claws for engaging with the side cover 213 at a plurality of positions. The side cover 213 is formed with a groove portion in which the engaging claw is caught and attached at a position facing the engaging claw. When the back cover 229 is assembled to the side cover 213, the engaging claws engage with the groove and act as a retainer. In addition, in order to more reliably reduce the detachment of the cover, the engaging portion may be adhesively fixed as appropriate.

Next, a method of shooting video content and a method of displaying a user operation screen will be described. FIG. 4 is a diagram showing a user operation screen for managing moving image contents. The user operation screen is a screen displayed on the display unit 303. A plurality of reduced images (thumbnail images) representing moving image contents are displayed on the display unit 303 along the H-axis (first axis) direction. The reduced image of the moving image content displayed on the display unit 303 is an image representing the captured moving image content (captured content). The image is not limited to a reduced image as long as it is an image representing captured content. The H axis is a time axis showing the flow of time. The central control unit 206 manages each moving image content by dividing it into a plurality of groups in the H-axis direction. In the example of FIG. 4, reduced images of groups A to E are displayed in the H-axis direction of the display unit 303. The number of groups of reduced images displayed on the display unit 303 may be any number.

In the example of FIG. 4, for each of the groups, one or more reduced images are displayed along the V-axis (second axis) direction. The V-axis is an axis in a direction orthogonal to the H-axis. The user can specify the group to which the reduced image belongs by performing a predetermined operation on the image pickup device 10. The central control unit 206 can associate the moving image content with the group according to the operation of designating the group to which the reduced image belongs.

The timeline 310 is displayed on the display unit 303 along the H-axis direction. One of one or a plurality of reduced images belonging to each of the groups is located on the timeline 310. The touch pad 301c of the first operation unit 301 can perform a slide operation in the direction in which the touch pad 301c extends. The timeline 310 includes a cursor 311. The direction of the slide operation of the touch pad 301c corresponds to the direction in which the cursor 311 on the timeline 310 is moved. The user can select any one reduced image from the reduced images of each group on the timeline 310 by sliding the touch pad 301c while holding the grip portion 304 with one hand.

When shooting moving image content, the user can press and operate the first button 301a or the second button 301b provided on the first operation unit 301. The first button 301a is a shooting instruction means for giving a shooting instruction, and when the first button 301a is pressed, shooting (take) of moving image content is started. The central control unit 206 classifies the moving image content acquired by pressing the first button 301a as the moving image content of a new group that does not belong to any of the existing groups. The central control unit 206 records the newly shot moving image content in the recording unit 210 together with the shooting information including the shooting conditions. For example, it is assumed that the first button 301a is pressed when the moving image contents of the groups A to D have already been shot. In this case, the central control unit 206 generates a new group E and manages the newly shot moving image content as the content 1 belonging to the group E. Then, the display control unit 207 controls to display a reduced image representing the content 1 of the group E. Video contents belonging to the same group are assigned different numbers. For example, the four moving image contents belonging to the group C are assigned numbers 1 to 4 in the order of shooting. In the example of FIG. 4, the display control unit 207 includes the content number in the reduced image corresponding to the moving image content.

The second button 301b is a re-shooting instruction means for instructing re-shooting such as re-shooting of the video content that has already been shot. When re-shooting, the user can select the moving image content to be re-shot by sliding the touch pad 301c and selecting the reduced image. When the second button 301b is pressed while the moving image content to be re-photographed is selected, the moving image content is re-photographed. The central control unit 206 recognizes the moving image content acquired by pressing the second button 301b as the moving image content acquired by re-shooting. Then, if the moving image content is not selected before the re-shooting, the central control unit 206 classifies the moving image content acquired by the re-shooting into the last shot group. The central control unit 206 records the re-photographed moving image content in the recording unit 210 together with the shooting information including the shooting conditions. For example, suppose that the second button 301b is pressed in a situation where the content 1 of the group D is finally shot. At this time, if the moving image content is not selected, the central control unit 206 manages the retaken moving image content as the content 2 belonging to the last shot group D. Then, the display control unit 207 causes the display unit 303 to display the reduced image of the content 2.

As described above, when the user slides the touch pad 301c, the cursor 311 on the timeline 310 moves in the H-axis direction. The user can select a reduced image of the moving image content to be re-photographed by operating the touch pad 301c before pressing the second button 301b. If a reduced image of the moving image content is selected before pressing the second button 301b, the central control unit 206 classifies the moving image content acquired by the re-shooting into the selected group. For example, suppose that the user operates the touch pad 301c to select a reduced image of group C, and then presses the second button 301b. In this case, the central control unit 206 manages the moving image content acquired by the re-shooting as the content 4 belonging to the group C. Further, the display control unit 207 displays a reduced image representing the content 4 in the group C of the display unit 303.

Finally, the central control unit 206 connects the video contents selected by the user from the plurality of video contents belonging to each group to generate one video content. The generated moving image content can be played back on the display unit 303. In the case of the example of FIG. 4, the central control unit 206 connects the moving image contents corresponding to the reduced images of each group on the timeline 310 to generate one moving image content. In the above-mentioned example, the H-axis is in the horizontal direction and the V-axis is in the vertical direction. For example, the direction of the H axis and the direction of the V axis may be an oblique direction, a direction along an arc, or the like.

Next, the management process of the video content will be described. FIG. 5 is a flowchart showing the flow of the video content management process. The central control unit 206 determines whether or not a shooting instruction has been given (S1). Whether or not a shooting instruction has been given is determined based on whether or not the first button 301a is pressed. If it is determined to be Yes in S1, the image pickup apparatus 10 starts shooting the moving image content (S2). The captured data is sequentially recorded in the recording unit 210. The central control unit 206 determines whether or not the shooting end instruction has been given (S3). When the first button 301a or the second button 301b is pressed, the central control unit 206 determines that the shooting end instruction has been given. When neither the first button 301a nor the second button 301b is pressed, the central control unit 206 determines that the shooting end instruction has not been given. If it is determined as No in S3, the flow returns to S3 and the shooting of the moving image content is continued. If it is determined to be Yes in S3, the shooting of the video content is completed, and the central control unit 206 classifies the shot data as the video content of a new group that does not belong to any group and manages it (S4). ). The central control unit 206 records the acquired moving image content in the recording unit 210 together with the shooting information including the shooting conditions at the time of shooting. Then, the process ends.

If No is determined in S1, the central control unit 206 determines whether a re-shooting instruction has been given (S5). When the second button 301b is pressed, the central control unit 206 determines that the re-shooting instruction has been given. When the second button 301b is not pressed, the central control unit 206 determines that the re-shooting instruction has not been given. If No is determined in S5, the flow returns to S1. If it is determined Yes in S5, the central control unit 206 determines whether the reduced image of the moving image content has been selected before the second button 301b is pressed (S6).

If it is determined to be Yes in S6, the image pickup apparatus 10 starts re-shooting the moving image content corresponding to the selected reduced image (S7). The re-photographed data is sequentially recorded in the recording unit 210. Then, the central control unit 206 determines whether or not the shooting end instruction has been given (S8). As in S3, it is determined whether or not the shooting end instruction has been given based on whether the first button 301a or the second button 301b is pressed. If No is determined in S8, the flow returns to S8. When it is determined to be Yes in S8, the central control unit 206 classifies and manages the captured data as the moving image content into a group to which the previously selected moving image content belongs (S9). The central control unit 206 records the moving image content in the recording unit 210 together with the shooting information including the shooting conditions at the time of shooting. Then, the process ends.

If No is determined in S6, the image pickup apparatus 10 starts re-shooting the moving image as a group to which the moving image content last shot belongs (S10). The re-photographed data is sequentially recorded in the recording unit 210. Then, the central control unit 206 determines whether or not the shooting end instruction has been given (S11). As in S3 and S8, it is determined whether or not the shooting end instruction has been given based on whether the first button 301a or the second button 301b is pressed. If No is determined in S11, the flow returns to S11. When it is determined to be Yes in S11, the central control unit 206 classifies and manages the captured data as moving image content into a group to which the last captured moving image content belongs (S12). The central control unit 206 records the moving image content in the recording unit 210 together with the shooting information including the shooting conditions at the time of shooting. Then, the process ends.

Next, the warning process of the first embodiment will be described. FIG. 6 is a flowchart showing the flow of warning processing of the first embodiment. The central control unit 206 determines whether or not a re-shooting instruction has been given (S101). As described above, whether or not the re-shooting instruction is given is determined based on whether or not the second button 301b is pressed. If No is determined in S101, the flow returns to S101. If it is determined to be Yes in S101, the central control unit 206 determines whether or not the moving image content has been selected before the second button 301b is pressed (S102). When it is determined Yes in S102, the central control unit 206 determines whether or not the last captured moving image content (last moving image content) is selected (S103). As described above, the moving image content can be selected by selecting the reduced image corresponding to the moving image content using the touch pad 301c.

If No is determined in S103, the central control unit 206 reads the shooting information of the moving image content selected in S102 from the recording unit 210. As described above, the shooting information includes information on shooting conditions when the moving image content is shot. In the first embodiment, the photographing condition is assumed to be the type of the lens unit 50. The central control unit 206 determines whether the type of the lens unit 50 when shooting the moving image content selected in S102 is the same as the type of the lens unit 50 currently mounted on the lens mount 211 (S104). ..

When No is determined in S104, the display control unit 207 causes the display unit 303 to display a warning and starts the warning display (S105). FIG. 7 is a diagram showing an example of the warning content displayed on the display unit 303. It is assumed that the name of the type of the lens unit 50 attached when the selected moving image content is shot is "ZOOOOM LENS 1". In this case, the display control unit 207 causes the display unit 303 to display the information “previous: ZOOOOM LENS 1” indicating the type of the lens unit 50 that was attached when the selected moving image content was shot. Further, it is assumed that the name of the type of the lens unit 50 currently mounted on the lens mount 211 is "ZOOOOM LENS 3". In this case, the display control unit 207 causes the display unit 303 to display the information “current: ZOOOOM LENS 3” indicating the type of the currently mounted lens unit 50.

Then, the display control unit 207 causes the display unit 303 to display a warning indicating that the type of the lens unit 50 is different along with the name of the lens unit 50. In the example of FIG. 7, a warning "The lens is different" is displayed on the display unit 303. By displaying the warning shown in the example of FIG. 7 on the display unit 303, the user is equipped with the type of the currently mounted lens unit 50 when shooting the moving image content to be re-shooted. It can be confirmed that it is different from the type of the lens unit 50. The user can also confirm information indicating the type of the lens unit 50 that was attached when the selected moving image content was shot. The user who has confirmed the type of the lens unit 50 can replace the lens unit 50 with the lens unit 50 that was attached when the selected moving image content was shot.

The central control unit 206 determines whether or not a re-shooting instruction has been given (S106). In S106, it is determined whether or not the re-shooting instruction has been given based on whether or not the first button 301a or the second button 301b has been pressed. If neither the first button 301a nor the second button 301b is pressed, the central control unit 206 determines that the re-shooting instruction has not been given. In this case, the central control unit 206 determines whether or not the lens unit 50 was replaced with the lens unit 50 that was attached when the moving image content selected in S102 was shot (S107).

As described above, the user can confirm the type of the lens unit 50 that is attached when the moving image content to be re-photographed is photographed because the lens unit 50 is different. Therefore, the user removes the currently mounted lens unit 50 from the lens mount 111 and replaces it with a lens unit 50 of the same type as the lens unit 50 mounted when the moving image content to be re-photographed is shot. can do. When the display control unit 207 recognizes that the lens unit 50 that was attached when the moving image content selected in S102 was shot has been replaced, the display control unit 207 ends the display of the warning displayed on the display unit 303 ( S108). Then, the flow shifts to S101. On the other hand, when No is determined in S107, the flow returns to S106 because the lens unit 50 that was attached when the moving image content selected in S102 was shot has not been replaced. In this case, the display control unit 207 continues to display a warning on the display unit 303.

When it is determined Yes in S106, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S109). In this case, the warning display ends even though the lens unit 50 that was attached when the moving image content selected in S102 was shot has not been replaced. The process of S109 is performed when the first button 301a or the second button 301b is pressed while the warning is displayed on the display unit 303. In this case, the user may have intentionally replaced the lens unit 50, which was attached when the moving image content selected in S102 was shot, with a lens unit 50 of a different type. Therefore, the display control unit 207 ends the display of the warning displayed on the display unit 303. As a result, the warning displayed on the display unit 303 is no longer displayed, and the display of the warning unnecessary for the user can be terminated. After the process of S109, the central control unit 206 controls to start shooting the moving image content. As a result, the image pickup apparatus 10 starts re-imaging (S110). Then, the warning process ends.

If No is determined in S102, since the moving image content has not been selected, the flow proceeds to S110 without displaying a warning, and the imaging device 10 starts re-imaging. Even if Yes is determined in S103, the flow proceeds to S110 without displaying a warning, and the image pickup apparatus 10 starts re-imaging. That is, when the second button 301b is pressed while the last shot moving image content is selected, even if the type of the lens unit 50 is different, the image is captured without displaying a warning. The device 10 starts re-imaging. When it is determined to be Yes in S103, it means that the second button 301b is pressed and a re-shooting instruction is input, and that the last moving image content is selected. In this case, even if the type of the lens unit 50 is different, it is highly possible that the user intentionally replaced the lens unit 50 when the last moving image content was shot. Therefore, when it is determined Yes in S103, the image pickup apparatus 10 does not display a warning on the display unit 303 even in a state where a predetermined warning condition is satisfied (a state in which No is determined in S104). Starts re-shooting.

Therefore, in the first embodiment, if the type of the lens unit 50 at the time of shooting the selected shot moving image content is different from the type of the currently mounted lens unit 50, a warning is given to the display unit 303. Is displayed. As a result, the user can confirm that the types of the lens units 50 are different. The user who confirms the warning can properly re-shoot the moving image content by replacing the lens unit 50 with the same type of lens unit 50 as the currently mounted lens unit 50.

<Second Embodiment>
Next, the second embodiment will be described. Since the video content management process is the same as that of the first embodiment, the description thereof will be omitted. FIG. 8 is a flowchart showing the flow of warning processing of the second embodiment. The central control unit 206 determines whether or not a re-shooting instruction has been given (S201). If No is determined in S201, the flow returns to S201. If it is determined to be Yes in S201, the central control unit 206 determines whether or not the moving image content has been selected before the second button 301b is pressed (S202). When it is determined Yes in S202, the central control unit 206 determines whether or not the last captured moving image content is selected (S203).

If No is determined in S203, the central control unit 206 reads the shooting information of the moving image content selected in S202 from the recording unit 210. As described above, the shooting information includes information on shooting conditions when the moving image content is shot. In the second embodiment, the photographing condition is assumed to be the focal length range of the lens unit 50. In the central control unit 206, the focal length range that can be used by the currently mounted lens unit 50 is the focal length range that can be used by the lens unit 50 that was mounted when the moving image content selected in S202 was shot. It is determined whether or not it is contained (S204).

When No is determined in S204, the display control unit 207 causes the display unit 303 to display a warning and starts the warning display (S205). FIG. 9 is a diagram showing an example of the warning content displayed on the display unit 303. It is assumed that the focal length range that can be used by the lens unit 50 that was attached when the selected moving image content was shot is "18 mm to 150 mm". In this case, the display control unit 207 causes the display unit 303 to display the focal length range information "previous: 18 mm-150 mm" that can be used by the lens unit 50 that was attached when the selected moving image content was shot. Further, it is assumed that the focal length range that can be used by the lens unit 50 currently mounted on the lens mount 211 is "15 mm to 45 mm". In this case, the display control unit 207 causes the display unit 303 to display the focal length range information "currently: 15 mm-45 mm" that can be used by the currently mounted lens unit 50.

Then, the display control unit 207 causes the display unit 303 to display a warning indicating that the usable focal length range is not included together with the focal length range information of the lens unit 50. In the example of FIG. 9, a warning "Does not include available focal lengths" is displayed on the display unit 303. As a result, the user recognizes that the currently mounted lens unit 50 does not include the focal length range that can be adjusted by the lens unit 50 that was mounted when the moving image content to be re-shot was shot. it can. Further, the display unit 303 displays the focal length range information of the lens unit 50 that was attached when the selected moving image content was shot. The user who has confirmed the focal length range information can replace the lens unit 50 with a lens unit 50 that includes the focal length range of the lens unit 50 that was attached when the selected moving image content was shot.

The central control unit 206 determines whether or not a re-shooting instruction has been given (S206). If No is determined in S206, has the central control unit 206 been replaced with a lens unit 50 including a focal length range that can be used by the lens unit 50 that was attached when the moving image content selected in S202 was shot? Is determined (S207). If No is determined in S207, the flow returns to S206. When it is determined Yes in S207, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S208). Then, the flow shifts to S201. On the other hand, if No is determined in S207, the flow returns to S206, and the display control unit 207 continues to display a warning on the display unit 303.

When it is determined Yes in S206, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S209). As a result, as in S109, when the user intentionally replaces the lens unit 50, an unnecessary warning is not displayed. Then, the image pickup apparatus 10 starts re-imaging (S210). After the processing of S210 is performed, the warning processing ends. If No is determined in S202, the flow proceeds to S210 without displaying a warning. Similarly, if No is determined in S203, the flow proceeds to S210, and re-shooting is started without displaying a warning. As a result, when the user intentionally replaces the lens unit 50, an unnecessary warning is not displayed.

Therefore, in the second embodiment, the focal length range of the currently mounted lens unit 50 is the focal length range that can be used by the lens unit 50 that was mounted when the selected captured moving image content was shot. If it does not contain, a warning will be displayed. The user who confirms the warning can replace the selected moving image content with a lens unit 50 including a focal length range that can be used by the lens unit 50 that was attached when the captured moving image content was shot. As a result, it is possible to prevent the re-shooting of the moving image content from being properly performed.

<Third Embodiment>
Next, the third embodiment will be described. Since the management process of the moving image content is the same as that of the first embodiment and the second embodiment, the description thereof will be omitted. FIG. 10 is a flowchart showing the flow of warning processing according to the third embodiment. The central control unit 206 determines whether or not a re-shooting instruction has been given (S301). If No is determined in S301, the flow returns to S301. If it is determined to be Yes in S301, the central control unit 206 determines whether or not the moving image content has been selected before the second button 301b is pressed (S302). When it is determined Yes in S302, the central control unit 206 determines whether or not the last captured moving image content is selected (S303).

If No is determined in S303, the central control unit 206 reads the shooting information of the moving image content selected in S302 from the recording unit 210. As described above, the shooting information includes the focal length information. In the third embodiment, the shooting condition is the focal length. The central control unit 206 determines whether the current focal length of the lens unit 50 is the same as the focal length when the moving image content selected in S302 is shot (the focal length when the shooting of the moving image content is started). Judgment (S304). When No is determined in S304, the display control unit 207 causes the display unit 303 to display a warning and starts the warning display (S305).

FIG. 11 is a diagram showing an example of the warning content displayed on the display unit 303. It is assumed that the focal length when the selected moving image content is shot is "30 mm". In this case, the display control unit 207 causes the display unit 303 to display the focal length information "previous time: 30 m" when the selected moving image content is shot. Further, it is assumed that the current focal length of the lens unit 50 is "18 mm". In this case, the display control unit 207 causes the display unit 303 to display the current focal length information “current: 18 mm” of the lens unit 50.

Then, the display control unit 207 causes the display unit 303 to display a warning indicating that the focal length is different together with the focal length information of the lens unit 50. In the example of FIG. 11, a warning "The focal length is different" is displayed on the display unit 303. This allows the user to recognize that the current focal length of the lens unit 50 is different from the focal length when the selected moving image content is captured. Further, the display unit 303 displays the focal length information of the lens unit 50 when the selected moving image content is shot. The user who has confirmed the display content displayed on the display unit 303 can adjust the focal length of the lens unit 50 to match the focal length of the lens unit 50 when the selected moving image content is shot.

The central control unit 206 determines whether or not a re-shooting instruction has been given (S306). When No is determined in S306, the central control unit 206 determines whether the focal lengths have been adjusted and the focal lengths are the same (S307). That is, the central control unit 206 determines whether the current focal length of the lens unit 50 matches the focal length of the lens unit 50 when the selected moving image content is shot. If No is determined in S307, the flow returns to S306. When it is determined Yes in S307, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S308). Then, the flow shifts to S301. On the other hand, if No is determined in S307, the flow returns to S306.

When it is determined Yes in S306, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S309). This prevents unnecessary warnings from being displayed if the user does not intentionally adjust the focal length. Then, the image pickup apparatus 10 starts shooting (S310). After the processing of S310 is performed, the warning processing ends. If No is determined in S302, the flow proceeds to S310 without displaying a warning. Similarly, if No is determined in S303, the flow proceeds to S210, and re-shooting is started without displaying a warning. This prevents unnecessary warnings from being displayed if the user does not intentionally adjust the focal length.

Therefore, in the third embodiment, when the focal length of the lens unit 50 when the selected video content that has been shot is shot does not match the focal length of the currently mounted lens unit 50, a warning is given. Is displayed. The user who confirms the warning adjusts the focal length of the lens unit 50. As a result, it is possible to re-shoot the video content at the same focal length as when the selected shot video content was shot, and it is possible to suppress that the re-shooting of the video content is not performed properly. ..

<Fourth Embodiment>
Next, the fourth embodiment will be described. Since the management process of the moving image content is the same as that of the first to third embodiments, the description thereof will be omitted. FIG. 12 is a flowchart showing the flow of warning processing according to the fourth embodiment. The central control unit 206 determines whether or not a re-shooting instruction has been given (S401). If No is determined in S401, the flow returns to S401. When it is determined Yes in S401, the central control unit 206 determines whether or not the moving image content has been selected before the second button 301b is pressed (S402). When it is determined Yes in S402, the central control unit 206 determines whether or not the last captured moving image content is selected (S403).

If No is determined in S403, the central control unit 206 reads the shooting information of the moving image content selected in S402 from the recording unit 210. As described above, the shooting information includes the focal length range information. In the fourth embodiment, the shooting condition is a focal length range. The central control unit 206 determines whether the focal length range that can be used by the lens unit 50 currently mounted on the lens mount 211 includes the focal length range that was used when the moving image content selected in S202 was shot. Judgment (S404). The determination of S404 is different from the determination of S204 of the second embodiment.

When No is determined in S404, the display control unit 207 causes the display unit 303 to display a warning and starts the warning display (S405). FIG. 13 is a diagram showing an example of the warning content displayed on the display unit 303 in the fourth embodiment. It is assumed that the focal length range used when shooting the selected moving image content is "30 mm to 120 mm". In this case, the display control unit 207 causes the display unit 303 to display the focal length range information "previous time: 30 mm-120 mm" used when the selected moving image content was shot. Further, it is assumed that the focal length range that can be used with the currently mounted lens unit 50 is "15 mm to 45 mm". In this case, the display control unit 207 causes the display unit 303 to display the focal length range information "currently: 15 mm-45 mm" that can be used by the currently mounted lens unit 50.

Then, the display control unit 207 causes the display unit 303 to display a warning indicating that the usable focal length range is not included together with the focal length range information of the lens unit 50. In the example of FIG. 13, a warning "Does not include available focal lengths" is displayed on the display unit 303. This allows the user to confirm that the currently mounted lens unit 50 does not include the focal length range used when shooting the selected shot video content. In addition, the focal length range information used when shooting the selected moving image content is displayed on the display unit 303. The user who confirms the warning displayed on the display unit 303 removes the lens unit 50 mounted on the lens mount 211. Then, the user can replace the selected lens unit 50 including the focal length range used when shooting the shot moving image content.

The central control unit 206 determines whether or not a re-shooting instruction has been given (S406). If No is determined in S406, the central control unit 206 determines whether the lens unit 50 including the focal length range used when shooting the moving image content selected in S402 has been replaced (S407). If No is determined in S407, the flow returns to S406. When it is determined Yes in S407, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S408). Then, the flow shifts to S401. On the other hand, if No is determined in S407, the flow returns to S406, and the display control unit 207 continues to display a warning on the display unit 303.

When it is determined Yes in S406, the display control unit 207 ends the display of the warning displayed on the display unit 303 (S409). As a result, as in S109, when the user intentionally replaces the lens unit 50, an unnecessary warning is not displayed. Then, the image pickup apparatus 10 starts shooting (S410). After the processing of S410 is performed, the warning processing ends. If No is determined in S402, the flow proceeds to S410 without displaying a warning. Similarly, if No is determined in S403, the flow proceeds to S410, and re-shooting is started without displaying a warning. This prevents unnecessary warnings from being displayed if the user does not intentionally adjust the focal length.

Therefore, in the fourth embodiment, if the focal length range of the currently mounted lens unit 50 does not include the focal length range used when the selected captured moving image content was captured, A warning is displayed. The user who confirms the warning can replace the attached lens unit 50 with a lens unit 50 including the focal length range used when the selected captured moving image content is captured. As a result, it is possible to prevent the re-shooting of the moving image content from being properly performed.
