Information necessary when the control program is executed is acquired from the input unit 36 or the communication unit 38, and the processing result is output from the output unit 37 to each unit of the image capturing apparatus as necessary.
[0017]
The principle of the image capturing apparatus of the present invention and an example of the hardware configuration thereof have been described above. The following is a more detailed description of two examples that specifically implement the principle.
First embodiment:
According to the first embodiment of the present invention, in an image capturing apparatus, some positional information is used to calculate the positional relationship between a subject and the apparatus, and the apparatus on the electric turntable is automatically rotated, and the lens of the apparatus is always used. The details will be disclosed by focusing on the technology that allows the subject to be directed toward the subject.
[0018]
Although various types of position information can be used, first, an outline of the operation of the first embodiment will be described in the case of using position information by GPS. The subject includes a mobile terminal with a built-in GPS. The image capturing device on the electric turntable includes a communication unit that can communicate with the GPS and the portable terminal. At the time of shooting, the communication unit identifies the subject from the number of the portable terminal registered as the shooting target, and transmits a position information request for the portable terminal to the portable terminal. When the mobile terminal receives the request, the mobile terminal transmits position information of the mobile terminal by GPS to the communication unit (the mobile terminal may then be configured to transmit position information to the communication unit at regular time intervals). The image capturing device calculates the positional relationship between the device and the subject from the built-in GPS location information and the received GPS location information of the mobile terminal, and rotates so that the lens of the device is always directed to the subject. Rotate the table.
[0019]
Further, as the position information, a position specifying method using a radio wave transmitter may be used. In this case, the subject carries a radio wave transmitter that transmits the ID by radio wave, and in the image capturing apparatus, a plurality of unidirectional antennas (about four) are arranged outward on the same circle. Then, the subject is specified by the ID received by the antenna of the image capturing device, and the direction and positional relationship of the subject with respect to the device are specified based on the strength of the radio wave at each antenna, thereby directing the lens of the device toward the subject. Rotate the turntable as shown.
[0020]
In addition, as the position information, the position may be specified using a position search service using a mobile phone number, or other usable information may be used.
FIG. 4 shows a rough flow of processing together with the configuration of the first embodiment.
First, the subject recognition unit 41 recognizes a subject to be photographed. Next, the subject position searching unit 42 searches for the position of the recognized subject, and the subject direction specifying unit 43 specifies the direction of the subject with respect to the image capturing apparatus based on the searched position. Based on the specified direction, the camera direction adjustment unit 44 adjusts and controls the camera direction of the apparatus. After the camera direction is determined, the lens adjustment unit 45 determines whether the lens should be telephoto (zoom) or wide angle (wide) from the relationship between the image range to be photographed and the subject, and adjusts the lens. . Then, the photographing unit 46 stores the photographed image in a storage medium or the like. The subject specifying unit 11 in the principle diagram of the present invention corresponds to the subject recognizing unit 41, the subject position searching unit 42, and the subject direction specifying unit 43, and the camera direction / lens adjusting unit 12 to the camera direction adjusting unit 44 and the lens. The adjustment unit 45 corresponds, and the imaging unit 46 corresponds to the imaging unit 13.
[0021]
Next, FIG. 5 shows a detailed processing flow of the first embodiment. FIG. 5 shows a processing flow of the image capturing apparatus that can use position information by GPS or position specifying method by a radio wave transmitter as position information by setting registration.
First, in S1, it is determined whether there is any instruction input. If there is (Y), the process proceeds to S17, and if not (N), the process proceeds to S2.
[0022]
In S2, it is determined whether or not automatic shooting is ON. If it is not ON (N), the process returns to S1. If it is ON (Y), the process proceeds to S3.
In S3, it is determined whether or not the portable terminal is registered as the subject. If it is not a portable terminal (N), it is determined that the radio wave transmitter is registered as the subject, and the process proceeds to S9. If it is a portable terminal (Y), the process proceeds to S4.
[0023]
In S4, the subject is identified from the number of the registered mobile terminal, and the position information by GPS is requested from the mobile terminal. In S5, the position information of the subject by GPS is received. In step S6, the position information obtained by the GPS of the image capturing apparatus itself is acquired. In step S7, the position information obtained by the subject GPS is compared with the position information obtained by the own GPS. In step S8, the photographing direction is specified based on the comparison result. Proceed to S13.
[0024]
By the way, if it is determined in S3 that the radio wave transmitter is registered as the subject, the ID transmitted from the transmitter is searched in S9, and the subject in which the ID received by the search is registered in S10. It is determined whether or not it matches the ID. If they do not match (N), the process returns to S9, and if they match (Y), the subject is specified thereby, and the process proceeds to S11. In S11, the transmission direction of the identified subject by the transmitter is searched. In S12, the transmission direction is specified, and the process proceeds to S13.
[0025]
In S13, the camera of the image capturing apparatus is driven in the specified direction. Normally, based on the specified direction, the direction of the subject with respect to the device and the direction of the camera are always adjusted (that is, the camera is driven so that the subject appears in the center of the shooting range). If the subject is within the shooting range, the camera may be adjusted so as not to be driven.
[0026]
In S14, the lens is driven so that the subject has a predetermined size, and the process proceeds to S15.
Here, the process of S14 will be described in more detail. “To make the subject have a predetermined size” means, for example, that “the subject has a size that is 50% to 70% of the entire shooting range”, and the shooting size of the subject is set in advance. The lens is adjusted by determining whether or not the setting is met. More specifically, as shown in the left diagram of FIG. 6A, the subject is captured within the shooting range, but the subject size is small. Assuming that the subject is a human, a human shape is extracted by image recognition or the like, and its outer frame rectangular area is obtained. The lens is driven so as to zoom (telephoto) so that the outer frame rectangular area becomes a predetermined size of the shooting range, and the subject is shot at an appropriate size as shown in the right diagram of FIG. In addition, in the left diagram of FIG. 6B, the subject is captured within the shooting range, but it protrudes and the subject size is too large. The lens is driven to become wide (wide angle) so that the outer frame rectangular area becomes a predetermined size of the photographing range. Then, as shown in the right diagram of FIG. 6B, the subject is photographed at an appropriate size.
[0027]
Now, the description returns to the flow of FIG. After the process of S14, the photograph is taken in S15, the photographed image is recorded on the recording medium in S16, and the process returns to S1.
By the way, when it progresses to S17 by determination of S1, it becomes the following flows. In S17, it is determined whether or not a subject registration instruction is received. If the subject registration instruction is not (N), the process proceeds to S24, and if the subject registration instruction (Y), the process proceeds to S18.
[0028]
In S18, the registration type (mobile terminal or transmitter) is displayed as a menu on a display monitor or the like. In S19, the type of registration is selected, and it is determined which is selected in S20. When the mobile terminal is selected (Y), the mobile terminal number is registered in S21, and the process returns to S1. When the transmitter is selected (N), the transmitter ID is searched in S22, the transmitter ID acquired by the search is registered in S23, and the process returns to S1.
[0029]
When the process proceeds to S24 as a result of the determination in S17, it is determined whether or not an automatic shooting ON / OFF instruction is given in S24, and if it is not an automatic shooting ON / OFF instruction (N), the process returns to S1. If the instruction is for automatic shooting ON / OFF (Y), the process proceeds to S25, where it is further determined whether or not automatic shooting is currently ON. If the automatic shooting is ON (Y), the automatic shooting is turned off in S26 and the process returns to S1. If the automatic shooting is OFF (N), the automatic shooting is turned ON in S27 and the process returns to S1.
[0030]
Note that in the flow of FIG. 5, shooting can be used for either still image shooting or moving image shooting.
As described above, the first embodiment has been described in detail. According to this configuration, even if the subject to be photographed is not known where it was before photographing, the subject can be surely found using a GPS or an ID transmitter, and the optimum You can shoot in size.
[0031]
Next, a second embodiment of the present invention will be described in detail.
Second embodiment:
According to the second embodiment of the present invention, when there are a plurality of subjects to be photographed in the image photographing device, all of the plurality of subjects are specified by image recognition, and each subject can be captured within the photographing range. The details will be disclosed focusing on the technique of adjusting the camera direction and lens of the photographing apparatus. Note that the identification of a plurality of subjects is not limited only to image recognition described below, and may be a method of identifying using a portable terminal carried by the subject, an ID transmitter, or the like.
[0032]
FIG. 7 shows a rough flow of processing together with the configuration of the second embodiment.
First, the subject recognizing unit 71 recognizes the subject to be photographed. There are one or more subjects. Next, the outer frame rectangular area specifying unit 72 specifies an outer frame rectangular area in which all subjects are included in the image temporarily stored in the image memory 34, and the object is captured within the shooting range of the image shooting apparatus. And whether or not the size for the entire photographing range is optimal. Based on the determination, the camera direction / lens adjustment unit 73 adjusts the direction of the camera or the lens to zoom (telephoto) or wide (wide angle). Then, the photographing unit 74 stores the photographed image in a storage medium or the like. The subject identifying unit 11 and the outer frame rectangular region identifying unit 72 correspond to the subject identifying unit 11 in the principle diagram of the present invention, the camera direction / lens adjusting unit 73 corresponds to the camera direction / lens adjusting unit 12, and The photographing unit 74 corresponds to the photographing unit 13.
[0033]
Here, determination by the outer frame rectangular area specifying unit 72 and adjusting the lens to zoom and wide based on the determination will be described in more detail with reference to FIG. Assume that four persons A, B, C, and D are registered as subjects. Now, it is assumed that an image obtained by photographing a plurality of subjects is stored in the image memory 34 as shown in the left diagram of FIG. The outer frame rectangular area specifying unit 72 recognizes an outer frame rectangular area in which all subjects can be accommodated. If the setting is made in advance so that the outer frame rectangular area with respect to the entire shooting range is 80% or more, the size shown in the left figure is not appropriate, so the lens zoom is performed and the right side of FIG. A plurality of subjects can be photographed as shown in the figure. Further, if the image memory 34 is photographed as shown in the left diagram of FIG. 8B, it can be recognized that all four subjects are not photographed, so the lens is widened (wide angle) and wider. All the subjects are photographed as shown in the right figure of FIG. 8B so that the range can be photographed. Also, if the lens wide operation alone is not appropriate, the camera direction is also adjusted.
[0034]
Next, FIG. 9 shows a detailed processing flow of the second embodiment.
Note that FIG. 9 shows details of processing when a still image is captured by a shutter operation. This is because it is easier to understand the processing when a still image is captured. However, the present invention is not limited to the case of shooting images, but can be applied to moving images if processing is performed so that images are shot continuously instead of shooting shutter images.
[0035]
First, in S31, it is determined whether or not there is a shutter operation. If it is not a shutter operation (N), the process proceeds to S42. If it is a shutter operation (Y), the process proceeds to S32.
In S32, it is determined whether or not the current mode is set to the group mode. If it is not the group mode (N), it is determined that the normal mode is set, and the process proceeds to S41. If it is the group mode (Y), the process proceeds to S33, and the image stored in the image memory 34 is analyzed. In S34, the presence / absence of each feature image of the registered subject is searched. The feature image is set and registered in S48 and later, and uses the color of the clothes of the human being, the length of the hair, the shape of the face, and the like. The existing technology is used for extracting and recognizing the feature image. In S35, it is determined whether or not there are feature images of all registered subjects. If not all (N), the lens is driven in two-stage wide (wide angle) in S36 so that a wider range can be photographed, and the process returns to S33. If it is determined in S35 that there are characteristic images of all the registered subjects (Y), the process proceeds to S37, and an outer frame rectangular area made up of each subject image is specified in S37. In S38, the ratio of the outer frame rectangular area specified in S37 to the entire shooting range is calculated. In S39, it is determined whether or not the ratio calculated in S38 is 80% or more. If it is not 80% or more (N), the lens is zoomed so that the outer frame rectangular area is 80% or more of the whole, and the camera direction is adjusted as necessary, and the process proceeds to S41. If it is determined in S39 that the ratio calculated in S38 is 80% or more (Y), the process proceeds to S41.
[0036]
In S41, the image in the image memory 34 is recorded on the recording medium, and the process returns to S31.
If it is determined in S31 that the shutter operation is not (N), setting processing such as change of shooting mode setting and subject registration setting is performed in S42 and subsequent steps, instead of shooting an image.
[0037]
In S42, it is determined whether or not it is an instruction to switch the shooting mode. If the mode is not switched (N), the process returns to S31. If the mode is switched (Y), the process proceeds to S43 to determine whether or not the shooting mode is currently the group mode. If it is the group mode (Y), the process proceeds to S44, the shooting mode is changed to the normal mode, and the process returns to S31. If it is determined in S43 that the current shooting mode is not the group mode (N), the process proceeds to S45, the shooting mode is changed to the group mode, and it is determined in S46 whether or not the subject has already been registered. If no subject is registered (N), the process proceeds to S48. If there is subject registration (Y), the process proceeds to S47, where it is determined whether or not the subject has been changed. If there is no subject registration change (N), the process returns to S31. If there is a change in subject registration (Y), the process proceeds to S48.
[0038]
After S48, subject registration processing is performed.
In S48, the subject to be registered is photographed individually. In S49, a feature portion of the subject is extracted from the photographed image, and in S50, the feature image is stored. In S51, it is determined whether or not the feature images have been stored for all the registration targets. If completed (Y), the process returns to S31. If not completed (N), the process proceeds to S48, and the characteristics of the remaining subjects are determined. Perform image storage processing.
[0039]
As described above, the second embodiment has been described in detail. According to this configuration, a plurality of subjects that can exist dispersedly at a plurality of positions can always be captured within the shooting range, and each subject can be shot with an optimal size for the entire shooting range. .
[0040]
Although two embodiments of the present invention have been described above, the present invention is not limited to the above-described actual forms, and various improvements and modifications can be made without departing from the scope of the present invention.
[0041]
【The invention's effect】
As described above in detail, according to the present invention, even when the subject to be photographed is not known where it was before photographing, the subject can be surely found and appropriately detected. It is possible to shoot. In addition, a plurality of subjects that can exist dispersedly at a plurality of positions can always be captured within the photographing range, and each subject can be photographed with an appropriate size for the entire photographing range.
