Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a camera that has a predetermined continuous control mode and outputs photographing information continuously generated therefrom.
[0002]
[Prior art]
Conventionally, in a camera having a mode in which a plurality of frames are photographed by operating an operation member or a mode in which autofocus (hereinafter abbreviated as AF) is driven a plurality of times, that is, in a camera having these continuous control modes, exposure such as shutter speed and aperture value is performed The shooting information related to the control is stored or recorded at the time of exposure, and after the shooting is completed, the stored or recorded information is confirmed.
[0003]
On the other hand, in recent years, with the advancement of AF technology and the like, the types of shooting information to be confirmed have increased, and there is a demand for confirmation of shooting information in more real time. For example, in the case where AF driving is repeatedly performed with the release button pressed to the first stage, in the so-called continuous AF mode or servo AF mode, photographing of subject distance, lens driving time, etc. for each control is performed. There is a request to confirm information on a personal computer.
[0004]
Here, Patent Document 1 discloses a camera configured to always output shooting information such as a subject distance and a lens driving time for each control. With this camera, it is possible to confirm such shooting information in real time (prior art (a)). On the other hand, Patent Document 2 discloses a camera configured to store shooting information such as subject distance and lens driving time in a random access memory (hereinafter abbreviated as RAM) built in the camera body. . This camera stores the shooting information in the RAM at the time of exposure, and then outputs the shooting information at the time of rewinding after the shooting. For this reason, the control interval does not extend, but the photographing information cannot be confirmed unless after photographing is finished (conventional technique (b)).

[Problems to be solved by the invention]
However, the prior art (a) has a problem that an output time is required between each control, and therefore the control interval is extended. In particular, when serially outputting data to a personal computer, the control interval is further extended.
[0008]
On the other hand, in the prior art (b), the control interval does not extend, but there is a problem that the photographing information cannot be confirmed in real time. Further, in the prior art (b), a battery for holding the contents of the RAM, that is, a backup battery is required, which causes a problem that the camera becomes large and costs increase, and an external device such as a printer is used. Since it is necessary to store all shooting information until the shooting information is output, for example, there is a problem in that the RAM built in the microcomputer that controls the entire camera has insufficient capacity. Furthermore, in the prior art (b), when the memory for storing the photographing information is an EEPROM, the writing time takes several tens of ms, and the control interval is eventually extended.
[0009]
Note that an EEPROM (electrically erasable programmable read only memory) is a kind of semiconductor memory, and is a nonvolatile memory that can electrically erase and rewrite stored information.
[0010]
The present invention has been made in view of the above problems, and controls a camera that collectively outputs shooting information in real time, or batch transfer of shooting information to a non-volatile storage element without extending the interval of continuous control. An object is to provide an apparatus.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a camera control device according to one embodiment of the present invention includes a control unit that continuously controls a shooting operation while an operation member is operated, and a plurality of shootings. information A random access memory capable of temporarily storing the image, and each time the shooting operation is executed, the random access memory stores the shooting in the shooting operation. information A cumulative writing unit for accumulating and writing, and the photographing stored in the random access memory in response to the end of the continuous photographing operation by releasing the operation of the operation member information And a serial output unit that outputs to the non-volatile storage unit outside the camera by serial communication in the order of writing.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0013]
FIG. 1 is a block diagram conceptually showing the controller of the camera according to the first embodiment of the present invention.
[0014]
In FIG. 1, shooting information input from an input terminal (IN) is information relating to shooting control such as a shutter speed, an aperture value, and a subject distance. Based on the information, the control unit 1 is provided in a camera body (not shown). Drives shutters, apertures, and photographing lenses.
[0015]
The continuous control input unit 2 is an operation member such as a release button provided on a camera body (not shown), and the control unit 1 is continuously controlled while these operation members are operated.
[0016]
For example, if the release button is continuously pressed to the first operation position (1stSW) of the release button, the AF operation is continuously performed, the photographing lens is always driven, and the subject is kept in focus. In other words, so-called continuous AF is performed. Further, when the release button is continuously pressed to the second operation position (2ndSW) of the release button, so-called continuous shooting is performed in which exposure control is continuously performed.
[0017]
The RAM 3 is a random access memory that temporarily stores shooting information, and stores the shooting information at that time each time control is performed. The cumulative writing unit 4 is means for designating the writing area (address) of the RAM 3 in accordance with the number of times of control. In the first control, the photographic information is written in the area R1 of the RAM 3. In the second control, the R2 of the RAM 3 is written. The shooting information is written in the area.
[0018]
Subsequently, if continuous control is performed, the area to be sequentially written into the areas R3, R4... Of the RAM 3 is updated, and the shooting information until the continuous control ends is accumulated.
[0019]
The continuous control end determination unit 5 is means for determining whether the continuous control is ended or whether the continuous control is ended. In the above continuous AF example, when the first stage of the release button is changed from the on state to the off state, it is determined that the continuous AF control is finished. In the above continuous shooting example, the release button 2 When the step changes from the on state to the off state, it is determined that the continuous exposure control is finished.
[0020]
The batch output unit 6 is a unit that collectively outputs the shooting information stored in the RAM 3 when the continuous control end determination unit 5 determines the end of the continuous control. For example, when four consecutive controls are performed and shooting information is stored in R1 to R4, which are the first to fourth areas of the RAM 3, the shooting information from R1 to R4 when the continuous shooting ends. Are output in order.
[0021]
The serial output unit 7 is a means for transmitting the shooting information output from the batch output unit 6 by serial communication to an external device outside the camera having a serial input terminal such as an IC card, an electronic notebook, or a personal computer. is there.
[0022]
The non-volatile storage unit 8 includes an EEPROM, a flash memory, or the like, which is a storage element that can be electrically written and erased, and is a means for storing shooting information output from the batch output unit 6.
[0023]
FIG. 2 is a timing chart for explaining the operation of the control unit of the camera according to the first embodiment of the present invention. First, as shown in FIG. 2 (a), when the signal from the continuous control input unit 2 turns from OFF to ON, the first control is performed as shown in FIG. 2 (b), and the first control is performed. When finished, the first shooting information is written in the R1 area of the RAM 3 as shown in FIG.
[0024]
Here, since the signal from the continuous control input unit 2 remains on, the second control is performed next. When the second control is finished, the second shooting information is written in the area R2 of the RAM 3.
[0025]
Here, since the signal from the continuous control input unit 2 remains on, the third control is performed next. When the third control is finished, the third shooting information is written in the area R3 of the RAM 3.
[0026]
When the signal from the continuous control input unit 2 is turned off, the next control is not performed, and the batch output unit 6 sequentially outputs the contents of the RAM 3 for serial communication as shown in FIG. 2 (d). To go.
[0027]
First, the shooting information of the R1 area of the RAM 3 is output, and when the external device receives it or writes it in the nonvolatile storage unit 8, the shooting information of the R2 area of the RAM 3 is output.
[0028]
Further, when the external device receives it or writes it in the non-volatile storage unit 8, it outputs the shooting information of the area R3 of the RAM 3. In the above embodiment, serial communication is a communication method in which digital data is transmitted or received bit by bit. In a general personal computer, about 1 ms is required to communicate 1 byte (8 bits) of data. It takes more time.
[0029]
For this reason, if there are many types and numbers of shooting information, the amount of data to be transmitted increases and the communication time becomes longer. Therefore, if shooting information is output serially every time control is performed, the interval of continuous control is extended.
[0030]
However, in the present invention, since the shooting information stored in the RAM 3 is output at a time when the continuous control is completed, the shooting information can be output or transmitted without extending the interval of the continuous control. it can.
[0031]
It is also possible to connect devices such as a hard disk device, a floppy disk device, and a printer in addition to the external device. Note that a general EEPROM takes about 10 ms to write 1-byte data.
[0032]
For this reason, if the number and type of shooting information is large, the amount of data to be written increases and the writing time becomes long. Therefore, if the shooting information is written in the nonvolatile storage unit 8 every time control is performed, the interval of continuous control is extended. End up.
[0033]
However, in the present invention, since the shooting information stored in the RAM 3 is collectively written in the nonvolatile storage unit 8 when the continuous control is finished, the shooting information is stored in the nonvolatile memory without extending the continuous control interval. The data can be written in the storage unit 8.
[0034]
FIG. 3 is a schematic diagram of a camera system according to the second embodiment of the present invention that outputs shooting information to an external device. In FIG. 3, the camera 10 includes a CPU 11 that controls the entire camera including a RAM and serial communication means, and the serial communication means is connected to the output terminal 12. On the other hand, an external device such as an IC card 14, an electronic notebook 15, or a personal computer 16 that has a serial input terminal and has storage and arithmetic processing capabilities receives imaging information from the CPU 11 of the camera 10 serially. As described above, the communication of the photographing information is performed collectively when the continuous control is finished.
[0035]
FIG. 4 shows a configuration of a camera that outputs photographing information to an EEPROM in the camera as a third embodiment of the present invention.
[0036]
In FIG. 4, the camera 17 has a CPU 18 having a RAM and data output means and an EEPROM 19. The data output terminal of the CPU 18 is connected to the data input terminal of the EEPROM 19, and shooting information output from the CPU 18 is stored in the EEPROM 19. Written. As described above, writing to the EEPROM 19 is performed collectively when the continuous control is completed.
[0037]
FIG. 5 is a block diagram of a circuit inside the camera that outputs shooting information as the second embodiment or the third embodiment of the present invention.
[0038]
In FIG. 5, a RAM 28 and a serial transmission buffer 29 are built in a CPU 27 as a one-chip microcomputer for controlling the entire camera. The imaging information during the continuous control is temporarily stored in the RAM 28, and is sequentially output from the serial transmission buffer 29 to the external device 34 and the EEPROM 35 when the continuous control ends. A signal from a first-stage switch (hereinafter abbreviated as 1stSW) 32 of a release button and a second-stage switch (hereinafter abbreviated as 2ndSW) 33 of a release button are input to the input port of the CPU 27.
[0039]
It is assumed that the release button is provided with a switch so that the 1st SW is always on when the 2nd SW is on. Further, analog signals from the photometric sensor 26 and the distance measuring sensor 25 are input to the AD conversion (analog / digital conversion) port A / D of the CPU 27, and these analog signals are converted into digital values in the CPU 27.
[0040]
The subject image that has passed through the photographic lens 20 is reflected by the main mirror 23 and then guided to the photometric sensor 26, and after being reflected by the sub mirror 24, it is guided to the distance measuring sensor 25.
[0041]
The photographic lens 20 is driven to the in-focus position by a lens driving unit 21 such as a motor based on a signal output from the output port I / O of the CPU 27, and the position after driving (subject distance) is detected by the distance encoder 22. , Input to the CPU 27.
[0042]
The focus position is detected in the CPU 27 based on the output of the distance measuring sensor 25. The exposure control unit 31 includes an aperture and a shutter, a motor and a magnet for driving the aperture, a shutter, and the like. The exposure control unit 31 controls the aperture value and the shutter speed by a signal output from the CPU 27 according to the output of the photometric sensor 26.
[0043]
FIG. 6 is a flowchart showing the processing of the CPU 27 in FIG.
[0044]
FIG. 7 is a timing chart showing the processing of the CPU when the release button is operated in FIG.
[0045]
Hereinafter, FIG. 6 will be described by taking the case where the release button is operated as shown in FIG. 7 as an example.
[0046]
First, in step S1, it is determined whether or not the 1st SW 32 is on. If it is on, the process proceeds to step S3, and if it is off, the process proceeds to step S2.
[0047]
In step S2, it is determined whether or not the 1st SW 32 has changed from on to off. If it has changed, the process proceeds to step S15. If it has not changed (it remains off), the process returns to step S1.
[0048]
Therefore, when the release button is not operated, the determination process of step S1 and step S2 is repeated. On the other hand, when the release button is pressed, the process proceeds to step S3. When the release button is released, the process proceeds to step S15. To do.
[0049]
First, a case where the release button is pressed will be described. In step S3, it is determined whether or not the 1st SW 32 has changed from OFF to ON. If it has changed, as shown in FIG. 7A, the process proceeds to step S4, and a variable n (a variable that specifies the write area of the RAM 28) is set. Set to “1”.
[0050]
After step S4, the process proceeds to step S6, where it is determined whether or not the 2ndSW 33 is off. If it is off, the process proceeds to step S7.
[0051]
In step S7, the output of the distance measuring sensor 25 is AD converted, and the process proceeds to step S8. In step S8, a defocus amount (focus shift amount) is calculated based on the AD conversion value of the distance measuring sensor 25, and the process proceeds to step S9.
[0052]
In step S9, as shown in FIG. 7C, the photographic lens 20 is driven to the in-focus position based on the defocus amount, and the process proceeds to step S10. Here, steps S7, S8, and S9 are basic processes of AF control, and continuous AF is performed by repeatedly performing these processes.
[0053]
In step S10, the subject distance data detected by the distance encoder 22 is stored in a predetermined area of the RAM 28 designated by the variable n. First, as shown in FIG. 7E, since the variable n is “1”, it is stored in the first area R1 of the RAM.
[0054]
After executing step S10, the process returns to step S1. Here, as shown in FIGS. 7A and 7B, when only the 1st SW 32 is on while the 2nd SW 33 is off, the process proceeds to steps S1, S3, and S5, and the variable n is set at step S5. Increase one.
[0055]
That is, the variable n is “2”. After execution of step S5, the process proceeds to step S6. Since the 2ndSW 33 remains off, the process proceeds to step S7, and AF control is performed in the same manner as described above.
[0056]
Here, since the variable n is “2”, in the next step S10, the subject distance data is stored in the second region R2 of the RAM 28, and the process returns to step S1. Here, as shown in FIGS. 7A and 7B, when the 2ndSW 33 is turned on while the 1st SW 32 is turned on, the process proceeds as steps S1, 3, S5, S6, and S11. Therefore, the variable n becomes “3”.
[0057]
In step S11, the output of the photometric sensor 26 is AD converted, and the process proceeds to step S12. In step S12, exposure control values such as a shutter speed and an aperture value are calculated based on the AD value (subject brightness) of the photometric sensor 26, and the process proceeds to step S13.
[0058]
In step S13, as shown in FIG. 7D, the shutter and the aperture are controlled based on the exposure control value, and the process proceeds to step S14. Here, steps S11, S12, and S13 are basic processes of exposure control, and continuous shooting is performed by repeating these processes.
[0059]
In step S14, the exposure control value is stored in a predetermined area of the RAM 28 designated by the variable n. At this time, since the variable n is “3”, it is stored in the third region R3 of the RAM 28 as shown in FIG.
[0060]
After execution of step S14, the process returns to step S1. Here, as shown in FIGS. 7A and 7B, when the 1st SW 32 and the 2nd SW 33 remain on, the process proceeds to steps S1, S3, S5, S6, and S11. Therefore, the variable n becomes “4”.
[0061]
Further, since the process proceeds to steps S11, S12, S13, and S14, exposure control is performed in the same manner as described above. Here, since the variable n is “4”, the exposure control value is stored in the fourth region R4 of the RAM 28 in step S14.
[0062]
At this time, as shown in FIG. 7B, when the 2ndSW 33 is turned off, the process proceeds to steps S1, S3, S5, S6, S7, S8, S9, and S10. Therefore, the variable n becomes “5” and AF control is performed, and subject distance data is stored in the fifth area R5 of the RAM 28 in step S10.
[0063]
Here, as shown in FIG. 7A, when the 1st SW 32 is also turned off, processing when the release button is released is performed as in steps S1, S2, and S15. First, in step S15, the variable m, which is a variable for designating the read area of the RAM 28, is set to “1”, and the process proceeds to step S16.
[0064]
In step S 16, the data in the RAM 28 in the area specified by the variable m is set in the serial transmission buffer 29. Initially, since the variable m is “1”, the shooting information of the first area R1 of the RAM 28 is set in the serial transmission buffer 29 as shown in FIG.
[0065]
After step S16, the process proceeds to step S17 and waits until transmission or output is completed. Note that this is sufficient when the shooting information is transmitted to the external device 34, but when shooting information is output to the EEPROM 35, it is necessary to wait until the writing on the EEPROM 35 side is completed.
[0066]
Specifically, an identification signal indicating that writing is in progress may be input from the EEPROM 35, and the signal may be waited while the signal is output, or the time required for writing is counted about 10 ms, and the time is waited. You may do it.
[0067]
When the waiting state for transmission or writing ends in step S17, the process proceeds to step S18 to determine whether or not the variable m and the variable n are equal, that is, whether or not all the photographing information stored in the RAM 28 has been output or transmitted. .
[0068]
If the variable m and the variable n are not equal, the process proceeds to step S19, and if equal, the process returns to step S1. In step S19, the variable m is incremented by 1, and the process returns to step S16.
[0069]
In the example of FIG. 7, since the shooting information is stored up to the fifth region R5 of the RAM 28, the variable n is “5”, and the processes of steps S16, S17, and S18 are performed until the variable m becomes “5”. Repeated.
[0070]
Therefore, the photographing information of R1 to R5 which are the first to fifth areas of the RAM 28 is sequentially output or written in the external device 34 or the EEPROM 35.
[0071]
FIG. 8 is a flowchart showing the processing of the CPU 27 in the case of performing the single AF control in FIG. 5, that is, the AF control until focusing is performed, and the AF control is stopped after focusing, and FIG. 8 is a timing chart when focusing is performed by three AF control based on the flowchart of FIG.
[0072]
First, in step S100 in FIG. 8, the process waits until the 1st SW 32 is turned on, and if it is turned on, the process proceeds to step S101. In step S101, it is determined whether or not the 1st SW 32 has changed from the off state to the on state. If it has changed, the process proceeds to step S102, and if it has not changed, that is, if it remains in the on state, the process proceeds to step S103.
[0073]
In step S102, the variable n is set to “0”, and the process proceeds to step S103. In step S103, the output of the distance measuring sensor 25 is AD converted, and the process proceeds to step S104.
[0074]
In step S104, the defocus amount, that is, the focus shift amount is calculated based on the AD conversion value of the distance measuring sensor 25, and the process proceeds to step S105. In step S105, based on the defocus value, it is determined whether or not it is in focus. If it is in focus, the process proceeds to step S109. If it is not in focus, that is, if it is out of focus, step S106. Migrate to
[0075]
Here, the in-focus state is determined as in-focus when the defocus value is within a predetermined range, and out-of-focus when the de-focus value is out of the range. In step S106, the photographic lens 20 is driven to the in-focus position based on the defocus amount, and the process proceeds to step S107.
[0076]
Here, steps S103, S104, S105, and S106 are basic processes of single AF. In step S107, “1” is added to the variable n, and the process proceeds to step S108. If the 1st SW 32 is pressed and AF control is started, the variable n becomes “1”.
[0077]
In step S108, subject distance data to the subject detected by the distance encoder 22 is stored in a predetermined area of the RAM 28 designated by the variable n. Therefore, the first subject distance data is stored in the first area R1 of the RAM 28.
[0078]
After step S108, the process returns to step S100.
[0079]
Here, as shown in FIGS. 9A, 9 </ b> B, and 9 </ b> C, assuming that the first lens 32 is turned on and the lens is in focus after the third driving, steps S <b> 103, S <b> 104, S <b> 105, S <b> 106, S <b> 107, S <b> 108 are performed. This process is performed three times.
[0080]
As a result, as shown in FIG. 9D, the respective subject distance data is stored in R1 to R3 which are the first to third areas of the RAM 28. If the in-focus position is reached by the third lens drive, the process proceeds from step S105 to step S109.
[0081]
Step S109 is a process of outputting subject distance data stored in the RAM 28 to the external device 34 or the EEPROM 35 as described above. Accordingly, as shown in FIG. 9E, the subject distance data stored in R1 to R3, which are the first to third areas of the RAM 28, are sequentially output.
[0082]
After step S109, the process proceeds to step S110, waits until the 1st SW 32 is turned off, and when it is turned off, the process returns to step S100.
[0083]
As described above, in the case of a camera having a single control mode such as single AF or single shooting, when the lens is driven a plurality of times even when the mode is set, it is included in the continuous control of the present invention. .
[0084]
The in-focus state corresponds to a continuous drive end signal. Therefore, the change in the subject distance data from when the release button is pressed until it is focused is output immediately after focusing.
[0085]
In the above-described embodiment, the case of continuous control has been described. However, when the camera has a single control mode such as single AF or single shooting and is set to that mode, once as in the conventional case. The shooting information may be output when the control is completed.
[0086]
Even in that case, there is no problem even if the shooting information is temporarily stored in the RAM 28 and then output. Also, when the continuous control is finished, the shooting information stored in the RAM 28 is transferred to the external device 34 or the EEPROM 35, so that the external device is always in a reception standby state and the shooting information transmitted from the camera is immediately displayed. By doing so, it is possible to check the operation of the camera in real time.
[0087]
In particular, even when the subject distance changes for each distance measurement, the AF control is performed at exactly the same time interval as the actual AF control, and the information can be confirmed immediately, so that the camera can be easily debugged and adjusted.
[0088]
In the above embodiment, the subject distance data is output to the external device 34 and the EEPROM 35 of the camera as shooting information related to the AF control. However, a defocus value and a distance sensor AD conversion value can also be output.
[0089]
Similarly, in the embodiment, the exposure control value is output to the external device 34 or the EEPROM 35 as the shooting information related to the exposure control. However, the lens information such as the focal length, the open aperture value, the minimum aperture value, The exposure mode, photometry mode, photometric sensor AD conversion value, film sensitivity, latitude, number of frames, film winding time, shutter charge time, etc. can also be output.
[0090]
As described above, in the above-described embodiment, since the shooting information stored in the RAM is transferred to the external device or the EEPROM when the continuous control is finished, the continuous control is performed even if the type and number of shooting information increase. The interval of does not extend.
[0091]
Therefore, shooting can be performed without missing a photo opportunity. Similarly, since the shooting information stored in the RAM is transferred to the external device or the EEPROM when the continuous control is finished, the capacity of the RAM may be small, and the RAM built in the CPU can be used. . Further, since a battery for backing up the RAM is not required, there is no cost and the camera is not enlarged.
[0092]

[0095]
If configured as described above, photographing information continuously generated in the camera is received by a control means including a one-chip microcomputer, and the control means executes a continuous control mode based on this photographing information.
[0096]
Further, the continuously generated photographing information is cumulatively stored in a random access memory in the one-chip microcomputer.
