  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a perspective view when the camera of the first embodiment of the present invention is viewed from the front.
A release switch 11 is disposed on the upper surface of the camera body 10, and a lens barrel 13 containing a photographing lens 12 is disposed on the front portion. The camera of the present embodiment is a camera equipped with a zooming function, and the lens barrel 13 can be expanded and contracted in the subject direction. The zoom magnification is changed by extending or contracting the lens barrel 13. The light that has passed through the lens barrel 13 is incident on a photosensitive film (not shown), and a subject image is recorded on the photosensitive film.

  The touch sensor 14 is provided on the front surface of the lens barrel 13 (end surface 13a on the subject side). In addition, if the touch sensor 14 and the housing portion of the camera body 10 are electrically connected, the touch sensor 14 may be activated when the photographer supports the camera body by hand during shooting. The touch sensor 14 is electrically insulated from the housing portion of the camera body 10.

FIG. 2 is a block diagram of the camera according to the first embodiment of the present invention.
The system control circuit 30 is a microcomputer and controls the entire camera.

  An AF sensor 31 and a photometric sensor 32 are connected to the system control circuit 30. At the time of focus adjustment, the AF drive mechanism 36 is controlled according to the control of the focus control circuit 35 based on the output signal from the AF sensor 31, and exposure control is performed. Sometimes, the shutter drive circuit 34 is controlled according to the control of the exposure control circuit 33 based on the output signal from the photometric sensor 32. The operation of the lens barrel 13 is controlled by the shutter drive circuit 34 and the AF drive mechanism 36, and the opening / closing operation and the focusing operation of the shutter are performed. The lens barrel 13 is controlled via a zoom drive mechanism 37 by operating a zoom switch (not shown), and a zooming operation is performed.

  A release switch lock circuit 50 is connected to the system control circuit 30.

  An operation switch 38 is connected to the system control circuit 30, and a shooting mode is set according to the operation of the operation switch 38. Further, the system control circuit 30 is connected to a display element 39 for displaying various setting states of the camera.

  The touch sensor 14 detects not only the presence / absence of contact of an object such as a finger but also the contact area (contact location and contact area) of the object, and notifies the system control circuit 30 of the detection result.

  Based on the detection result of the touch sensor 14 and the zoom magnification determined by the position of the lens barrel 13, the system control circuit 30 determines whether an object is in the shooting range. The release switch lock circuit 50 locks the release switch 11 and prohibits the release switch 11 from being pressed when the system control circuit 30 determines that an object is in the shooting range. That is, control for prohibiting photographing is performed.

Hereinafter, the operation at the time of shooting by the camera of the first embodiment will be described.
FIG. 3 is a diagram illustrating an operation flow at the time of shooting by the camera of the first embodiment. FIG. 4 is a diagram for explaining determination processing at the time of shooting by the camera of the first embodiment.
When the camera is set to the shooting mode and the release switch 11 is pressed halfway (step S1), the system control circuit 30 determines whether or not the touch sensor 14 touches the finger (step S2). When it is detected by the touch sensor 14 that there is a finger contact (step S2: YES), the system control circuit 30 determines the finger contact area according to the detection result of the touch sensor 14 (step S3).

  Next, the system control circuit 30 adds a margin area to the finger contact area determined in step S3 (see FIGS. 4B and 4D), and estimates the finger that is expected to be present. The area is determined (step S4). Next, the system control circuit 30 determines whether or not the estimated finger region is on the photographing lens 12 (step S5).

  When the estimated finger area is placed on the photographing lens 12 (step S5: YES), the system control circuit 30 determines whether or not the estimated finger area is placed on the photographing range determined by the current zoom magnification. It is determined whether or not a finger is in the range (step S6). Even if the estimated finger region is placed on the photographing lens 12, the finger may not enter the photographing range depending on the zoom magnification. For this reason, it is possible to accurately determine whether or not a finger is in the shooting range by performing the process of step S6.

  If it is determined that a finger is in the shooting range (step S6: YES), the system control circuit 30 instructs the release switch lock circuit 50 to lock the release switch 11. By this instruction, the release switch 11 is locked and photographing is prohibited (step S7). Then, the photographer is notified by the display element 39 or the like that photographing cannot be performed (step S8).

  If no finger contact is detected in step S2, if it is determined in step S5 that the estimated finger area does not cover the shooting lens 12, or if it is determined in step S6 that no finger is in the shooting range. In any case, the system control circuit 30 maintains the photographing enabled state without giving any specific instruction to the release switch lock circuit 50 (step S9). When the release switch 11 is fully pressed and a shooting instruction is issued, shooting is performed in accordance with the shooting instruction (step S10), and a shot image is recorded on the film by this shooting.

  As described above, according to the camera of the present embodiment, even when a finger touches the touch sensor 14, shooting can be performed if the finger is not within the shooting range. When the finger is in the shooting range, shooting is prohibited. For this reason, it is possible to shoot without missing a photo opportunity while preventing finger exposure.

  In the present embodiment, a film camera is taken as an example, but a digital camera that outputs a subject image as an imaging signal by an imaging element such as a CCD image sensor and generates captured image data from the output imaging signal is also illustrated in FIG. It is possible to carry out the processing shown in FIG.

  In the present embodiment, the processing after step S2 is performed after the release switch 11 is half-pressed. However, the processing after step S2 may be performed while the camera is activated.

(Second embodiment)
FIG. 5 is a block diagram of a camera according to the second embodiment of the present invention. In FIG. 5, the same components as those in FIG.
The camera shown in FIG. 5 adds an imaging element 54 that outputs a subject image such as a CCD image sensor as an imaging signal in the lens barrel 13 of FIG. 2, and further adds a predetermined image signal to the imaging signal output from the imaging element 54. A signal processing unit 55 that generates the image data by performing the signal processing, a motion detection sensor 56 such as an angular velocity sensor that detects the motion of the camera, and a recording medium 53 that records the image data generated by the signal processing unit 55. Is added.

Hereinafter, an operation when the touch of the object is detected by the touch sensor 14 in the camera of the second embodiment will be described.
FIG. 6 is a diagram illustrating an operation flow when the touch of the object is detected by the touch sensor in the camera of the second embodiment. FIG. 7 is a diagram for explaining processing for recognizing a region where a finger exists.

  When the camera is set to the shooting mode, an image pickup signal is periodically output from the image pickup device 54, and through image data for a through image to be displayed on the display device 39 is generated by the signal processing unit 55 based on the image pickup signal. The

  When the touch sensor 14 detects a finger contact (step S21), the system control circuit 30 zooms that is determined by the detection result of the touch sensor 14 (finger contact location and finger contact area) and the position of the lens barrel 13. From this, an assumed area, which is an area where a finger is assumed to exist in the imaging range, is obtained (step S22). For example, the system control circuit 30 performs steps S3 and S4 in FIG. 3 to obtain an estimated finger area, and adds a blank area to the estimated finger area in the imaging range (FIGS. 7A and 7B). A region D as shown in FIG.

  Next, the system control circuit 30 measures the luminance value of each pixel data of the image data corresponding to the assumed region D among the through image data generated from the imaging signal output from the imaging element 54 at the time of step S21. (Step S23). Next, the system control circuit 30 recognizes an area corresponding to pixel data whose measured luminance value is equal to or less than a threshold value as a finger area where a finger is present (step S24). It is considered that the brightness of the area where the finger exists is extremely lower than that of the other areas. Therefore, by looking at the luminance value of the image data corresponding to the assumed area D, it is possible to recognize the area where the finger is present.

  Next, the system control circuit 30 temporarily stores the recognized finger area information E in a memory (not shown) (step S25).

The system control circuit 30 can also determine whether or not the finger is in the shooting range determined by the current zoom magnification according to the information E. However, if the determination is made using only the information E, there is a possibility of erroneous recognition. For example, as shown in FIG. 7A, consider a case where a subject B having a low luminance value exists in the assumed area D in addition to the finger. In this case, as shown in FIG. 7 (c), a region combining the subject B and the actual finger is recognized as a finger region.
Therefore, in the present embodiment, the system control circuit 30 recognizes the finger area twice based on the imaging signal obtained by the two times of photographing performed by changing the position of the camera, and the two recognized finger areas are By recognizing the overlapping region as a true finger region, the influence of the subject portion having a low luminance value other than the finger is removed to prevent erroneous recognition.

  After step S25, the system control circuit 30 issues an instruction to move the camera through the display element 39 or the like (step S26). When it is detected by the motion detection sensor 56 that the amount of motion of the camera is equal to or greater than the threshold (step S27: YES), the system control circuit 30 performs the same processing as steps S22 to S25.

  That is, the system control circuit 30 is assumed that the finger is present in the shooting range from the detection result of the touch sensor 14 (finger contact location and finger contact area) and the zoom magnification determined by the position of the lens barrel 13. An assumed area, which is an area, is obtained (step S28), and image data corresponding to the assumed area assumed in step S28 among the through image data generated from the imaging signal output from the imaging element 54 at the time of step S27: YES. The luminance value of each pixel data is measured (step S29), the area corresponding to the pixel data whose measured luminance value is equal to or less than the threshold value is recognized as a finger area (step S30), and the information F of the recognized finger area is stored in the memory. Temporarily store it (step S31).

  Next, the system control circuit 30 compares the information E stored in step S25 with the information F stored in step S31, and the finger region represented by the information E overlaps the finger region represented by the information F. The area is recognized as a true finger area, and information G of the recognized true finger area is temporarily stored in the memory (step S32).

  When the release switch 11 is pressed halfway and an instruction to prepare for shooting is given (step S33: YES), the system control circuit 30 obtains the shooting range at the time when the instruction is given by the zoom magnification, and the obtained shooting range. It is determined whether or not the finger area represented by the information G enters (step S34).

  If it is determined that the finger does not enter the shooting range, the process of step S9 in FIG. 3 is performed. If it is determined that the finger enters the shooting range, the process of step S7 of FIG. 3 is performed.

  As described above, according to the camera of the present embodiment, the finger area is recognized based on the image data obtained by shooting, and it is determined whether the finger is in the shooting range according to the finger area. it can. Therefore, the determination accuracy can be improved as compared with the determination method of the first embodiment.

  In addition, the finger area is recognized twice based on the image data obtained by the two shootings performed by moving the camera, and the true finger area is recognized in consideration of the result of the two finger recognitions. Therefore, erroneous recognition of the finger area can be prevented, and it can be determined with higher accuracy whether or not the finger is in the shooting range.

  Note that in the camera of the first embodiment, steps S22 to S25 in FIG. 6 are performed instead of steps S3 to S5 in FIG. 3, and whether or not a finger is in the shooting range in step S6 in FIG. May be determined according to information E.

(Third embodiment)
FIG. 8 is a perspective view when the camera of the third embodiment of the present invention is viewed from the front. In FIG. 8, the same components as those of FIG.
The camera of the third embodiment has a configuration in which a light emitting unit that emits auxiliary light is added to the camera shown in FIG. As shown in FIG. 8A, the light emitting unit is a point light source 57 provided on the front surface of the camera body, a ring light source 58 provided on the periphery of the touch sensor 14 as shown in FIG. is there.

FIG. 9 is a block diagram of a camera according to the third embodiment of the present invention. 9, the same components as those in FIG. 5 are denoted by the same reference numerals.
The camera shown in FIG. 9 has a configuration in which a light emitting unit 57 or 58 and an auxiliary light driver circuit 59 for driving the light emitting unit 57 or 58 are added to the camera shown in FIG.

  In the camera of the second embodiment, the system control circuit 30 recognizes the finger area according to the brightness value of the image data. This recognition method is used when the brightness of a subject other than the finger is bright to some extent (photographed in the daytime). Is effective). In the case of shooting at night, etc., the brightness of the entire assumed area falls, so even if the finger area is recognized according to the brightness value of the image data, it is determined whether the finger area is darkened by the finger. It is difficult. In the case of the camera of the second embodiment, at the time of night shooting, there is a possibility that the assumed area = the finger area may be recognized even if the finger is not actually in the assumed area. It is possible to end up.

  Therefore, in this embodiment, when the area of the finger area recognized from the luminance value of each pixel data of the image data corresponding to the assumed area is equal to or larger than a threshold (for example, 90% of the assumed area), in this case Since it is difficult to accurately recognize the area, the system control circuit 30 causes the light emitting unit 57 or 58 to emit auxiliary light, and the through image data generated from the imaging signal obtained when the auxiliary light is emitted is displayed. Compare the image data corresponding to the assumed area with the image data used in the recognition process before the auxiliary light emission, and re-recognize the area corresponding to the pixel data whose luminance value has changed significantly as a result of the comparison as the finger area It is said.

Hereinafter, an operation when the touch of the object is detected by the touch sensor 14 in the camera of the third embodiment will be described.
FIG. 10 is a diagram illustrating an operation flow when the touch of the object is detected by the touch sensor in the camera of the third embodiment. FIG. 11 is a diagram for explaining processing for recognizing a region where a finger exists.

  After step 24 or step S30 of FIG. 6, the system control circuit 30 determines the size of the recognized finger area (step S41). When the area of the finger region is not equal to or greater than the threshold value, the system control circuit 30 performs the processing after step S25 or step S31.

  When the area of the finger region is equal to or larger than the threshold value, the system control circuit 30 controls the auxiliary light driver circuit 59 to emit auxiliary light from the light emitting unit 57 or 58 (step S42).

  Next, the system control circuit 30 corresponds to the assumed region calculated in step S22 or step S28 of the through image data generated from the imaging signal output from the imaging device 54 by imaging performed by emitting auxiliary light. The image data X (see FIGS. 11B and 11D) is compared with the image data Y used to perform finger recognition in step S24 or S30 (see FIGS. 11A and 11C). Then, the finger area is recognized again (step S43). For example, pixel data whose luminance value has changed by a threshold value or more is extracted from the image data X and the image data Y, and an area corresponding to the extracted pixel data is re-recognized as a finger area.

  Next, the system control circuit 30 temporarily stores the re-recognized finger area information E (or F) in the memory (step S44). Thereafter, the process proceeds to step S26 or step S32.

  As described above, according to the camera of the present embodiment, when the subject is too dark and it is difficult to accurately recognize the finger area, the image data obtained when the auxiliary light is emitted and the auxiliary light is not emitted. Since the finger region is re-recognized by comparison with the obtained image data, it is possible to determine with high accuracy whether or not the finger is in the shooting range even during night shooting or the like.

  Note that the processing described in the present embodiment is also applicable when the finger area is recognized only once, that is, when steps S22 to S25 are performed instead of steps S3 to S5 in FIG. In this case, in the process of step S6 performed after step S44 of FIG. 10, it is determined whether or not the finger is in the shooting range according to the information E recognized in step S24 or the information E re-recognized in step S44. You should do it.

(Fourth embodiment)
In the cameras of the first to third embodiments, the system control circuit 30 performs control so that shooting is prohibited when it is determined that a finger is in the shooting range, and the finger is not in the shooting range. Control is made so that photographing is permitted when it is determined. On the other hand, the camera of the present embodiment allows shooting regardless of whether or not a finger is in the shooting range, and when the finger is in the shooting range, shooting obtained by shooting according to the shooting instruction The captured image data is processed and recorded so that the finger portion is deleted from the image data.

  The configuration of the camera of the fourth embodiment is the same as that of the camera of the first embodiment (provided that it is not a film camera but a digital camera), the camera of the second embodiment, or the camera of the third embodiment. is there.

FIG. 12 is a diagram illustrating an operation flow of the camera of the fourth embodiment. FIG. 13 is a diagram for explaining an example of a method of processing captured image data.
When the determination in step S6 in FIG. 3 or step S34 in FIG. 6 is YES, the system control circuit 30 of the camera of the fourth embodiment waits for the shooting instruction, and the release switch 11 is fully pressed to issue the shooting instruction. Then, the imaging device is controlled in accordance with the imaging instruction to perform imaging, and captured image data generated from the imaging signal output from the imaging device by this imaging is acquired. Then, the captured image data is processed so as to delete the portion corresponding to the estimated finger region determined in step S4 or the finger region recognized in step S32 from the acquired captured image data. The previous photographed image data is recorded on a recording medium (step S61).

  As a processing method of photographed image data, for example, as shown in FIG. 13, there is a method of trimming photographed image data so that an estimated finger region portion or finger region portion of photographed image data before processing is deleted. . The processing method may be set in advance by the user.

  As described above, according to the camera of the present embodiment, since it is possible to perform shooting even when a finger is in the shooting range, a photo opportunity is not missed. Further, since the photographed image data recorded by this photographing does not include a finger, it is not necessary to perform a process for deleting the finger later, and the burden on the user can be reduced. In addition, since the photographed image data before processing is also recorded, the photographed image data can be selected.

(Fifth embodiment)
FIG. 14 is a block diagram of a camera according to the fifth embodiment of the present invention. In FIG. 14, the same components as those in FIG.
In the camera shown in FIG. 14, a shift lens 61 that is movable perpendicular to the optical axis is added to a part of the photographing lens in the lens barrel 13 shown in FIG. The configuration is such that a partial drive circuit 60 and a position detection unit 52 for detecting the position of the shift lens 61 are added.

  The system control circuit 30 performs optical camera shake correction control by controlling the shift unit drive circuit 60 and changing the position of the shift lens 61 in accordance with the amount of camera motion detected by the motion detection sensor 56.

  The system control circuit 30 prevents the estimated finger area determined by the method described in the first embodiment or the finger area recognized by the method described in the second to third embodiments from entering the imaging range. Also, the shift lens 61 is moved to control the moving range.

FIG. 15 is a diagram illustrating an operation flow of the camera of the fifth embodiment. FIG. 16 is a diagram for explaining the finger image deletion method of the camera according to the fifth embodiment. In FIG. 15, the same processes as those in FIG.
When the determination in step S6 or step S34 in FIG. 3 is YES, the system control circuit 30 of the camera of the fifth embodiment prepares to move the shift lens 61 in a direction in which the estimated finger region or finger region does not enter the shooting range. Start (step S51). The movement amount M1 of the shift lens 61 is calculated based on the estimated finger region determined in step S6 or the finger region recognized in step S32.

  Next, the system control circuit 30 determines whether or not the optical camera shake correction function is turned on (step S52). When the optical camera shake correction function is OFF, the system control circuit 30 determines that the position where the shift amount 61 is added to the current position of the shift lens 61 (lens movement position) is the mechanical end of the shift lens 61 (the shift lens 61 is movable). It is determined whether or not both ends on a straight line are exceeded (step S53).

  If the lens movement position is beyond the mechanical end of the shift lens 61, in this case, it can be determined that even if the shooting range is moved as much as possible, a finger enters the shooting range. For this reason, the system control circuit 30 performs the processing after step S7.

  If the lens movement position does not exceed the mechanical end of the shift lens 61, in this case, it can be determined that if the shooting range is moved, the finger cannot enter the shooting range. Therefore, the system control circuit 30 moves the shift lens 61 by the movement amount M1 as shown in FIG. 16 (step S60). After moving the shift lens 61, the system control circuit 30 performs the processing after step S9.

  If the optical camera shake correction function is ON in step S52, the system control circuit 30 moves when the movement amount (correction range) of the shift lens 61 necessary for maximizing the optical camera shake correction performance is M2. It is determined whether or not the sum of the amount M1 and the movement amount M2 exceeds the distance M3 from the current position of the shift lens 61 to the mechanical end of the shift lens 61 (step S56).

  If (M1 + M2) is equal to or less than M3, in this case, even if the shift lens 61 is moved by M1, the distance of M2 remains to the mechanical end, and optical camera shake correction can be performed without any problem. The system control circuit 30 performs the processing after step S60.

  If (M1 + M2) exceeds M3, in this case, if the shift lens 61 is moved by M1, the distance of M2 is not secured to the mechanical end, and the optical image stabilization performance cannot be fully exhibited. . For this reason, the system control circuit 30 inquires of the user via the display element 39 whether or not the finger image deletion function is prioritized over the optical camera shake correction performance (step S57).

  When an instruction giving priority to the optical image stabilization performance is given, the system control circuit 30 inquires of the user via the display element 39 whether or not to take a picture even if the finger image cannot be completely deleted (step S58).

  If there is a NO instruction in step S58, the system control circuit 30 performs the processing after step S7. If YES is determined in step S58, the system control circuit 30 moves the shift lens 61 by (M3-M2) (step S59), and then performs the processing from step S9. Since M1> (M3-M2), in the process of step S59, the shooting range cannot be moved until the finger does not completely enter the shooting range, but the range where the finger is still captured can be reduced as much as possible. .

  As described above, according to the camera of the present embodiment, the shift lens 61 can be moved so that the finger does not enter the shooting range, so that the probability that shooting is prohibited can be reduced, and the shutter You can increase the probability of not missing a chance.

  In FIG. 15, after step S56: YES, the process may be directly transferred to step S7 without performing steps S57 and S58.

  In the present embodiment, the photographing range is moved by moving the shift lens 61. However, the photographing range may be moved by moving the imaging element 54, or the shift lens 61, the imaging element 54, and the like. May be moved to move the shooting range.
