Fig. 4 is the process flow diagram of the focal length input processing of present embodiment.Focal length input processing is carried out before common shooting process (image pickup mode) when the power supply of camera body 1 is connected.As shown in Figure 4, when user operation power knob 20a makes the power supply of camera body 1 connect, judge, in camera body 1, whether lens changeable or interface adapter 2 (S201) are installed.Particularly, CPU10 attempts communicating with the accessory installed via fuselage interface 22.When accessory be possess with the lens changeable (not shown) of the interface of the same specification of fuselage interface 22 or interface adapter 2 time, CPU10 obtains intrinsic information from the flash rom 32 of the flash rom of this camera lens, interface adapter 2, and carries out the identification of accessory.For convenience of explanation, possessing with the intrinsic information that stores in the flash rom of the lens changeable of the lens interface of the same specification of fuselage interface 22, identifying information and the focus information of this lens changeable is comprised.When being judged to camera body 1 to be provided with lens changeable or interface adapter 2 (S201: yes), enter into S202.When not comprising the identifying information of interface adapter when interface adapter does not possess flash rom, in the intrinsic information that obtains of CPU, when fuselage interface 22 there is no an installation fitting etc., when can not communicate with the accessory installed via fuselage interface 22, be judged as camera body 1 not being installed lens changeable or interface adapter 2 rear (S201: no), enter into S203.
In S202, judge that can CPU10 detect the focal length of lens changeable according to the intrinsic information obtained from accessory.In the present embodiment, as mentioned above, even if be connected with lens changeable 3 by interface adapter 2, CPU10 can not obtain the focus information of lens changeable 3.Therefore, when camera body 1 is provided with interface adapter 2, is judged to be the focal length (S202: no) that can not detect lens changeable 3, enters into S203.When camera body 1 being directly provided with lens changeable, CPU10 can detect focal length (S202: yes) according to the intrinsic information of lens changeable, and enters common photograph mode.In addition, when entering common photograph mode, the value of focal length that CPU10 can be utilized the value of the focal length detected or be determined by following focus settings process, by hand shaking correction unit 11, accurately controls the anti-vibration action of imaging apparatus 12.In addition, the value of focal length can also be additional to as image information the view data photographed.
Fig. 5 is the process flow diagram of the focus settings subprocess of present embodiment.When proceeding to S203, display part 19 shows focal length input picture, and this subprocess starts.(a) of Fig. 8, (b) of Fig. 8 represent the focal length input picture in this subprocess.At S301, become the state that manually can input focal length.(a) of Fig. 8 shows the focal length input picture in S301.For convenience of explanation, in the present embodiment, if user once utilized this subprocess to determine focal length in the past.Near the central authorities of focal length input picture, show manual input value, the left side in focal length input picture, temporally sequence is shown as historical information for the history value H of user's setting in the past.In addition, when user does not set focal length in the past, the value that history value H is preset is shown.The manual input value V shown in S301 is the value of the focal length determined last time.When focal length input picture is displayed on display part 19, proceed to S302.
As shown in (a) of Fig. 8, in the present embodiment, the initial position of cursor C is the most significant digit row of manual input value V.As user operation LeftArrow 20e or right direction key 20g, cursor C moves at each interdigit.In addition, cursor C can most significant digit row and minimum rank between loopy moving.As directionkeys 20f in user operation or lower directionkeys 20h, show the value increase and decrease of the position of cursor C.User operates cross key 20b thus manual input value V is changed to expectation value.
In S302, user operates cross key 20b, determines whether thus to change manual input value V.When user to operate cross key 20b and makes cursor C suitably move and be judged to change manual input value V (S302: yes), display change after manual input value V (S303), proceed to S304.
In S304, user operates OK button 20c, judges whether focal length input terminates thus.When user operates OK button 20c (S304: yes), proceeding to S305, performing the subprocess of the setting value for manual input value V being defined as focal length as described below.When user does not operate OK button 20c (S304: no), proceed to S302.
Here, the function of electronics index dial 20i is described.When user rotates electronics index dial 20i, cursor C moves from manual input value V to any one value of the history value H be presented at focus input picture.(b) of Fig. 8 represents that use electronics index dial 20i makes cursor C move to the state (history selection mode) of history value H.In the present embodiment, when turn right electronics index dial 20i time, cursor C moves from the top down in turn in history value H side, when turn left electronics index dial 20i time, cursor C moves from bottom to top in turn in history value H side.Manual input value V shows the history value H selected by cursor C.In addition, when using electronics index dial 20i, cursor C can loopy moving between the value of the topmost of history value H (in the drawings, " 15.0 ") and manual input value V or between the value (in the drawings, " 135.0 ") of the foot of history value H and manual input value V.In the present embodiment, under history selection mode during user operation right direction key 20g, cursor C moves to manual input value, and manual input value is updated to the value of the history value H selected by cursor C before cursor C just will move.Then, user can change manual input value by operating cross key 20b as mentioned above.
When user does not operate cross key 20b in S302 (S302: no), then proceed to S306.In S306, user operation electronics index dial 20i, cursor C moves thus, has determined whether selection history value H.As user operation electronics index dial 20i (S306: yes), cursor C moves to history value H, becomes history selection mode (S307), proceeds to S308.When user does not operate cross key 20b and electronics index dial 20i (S306: no), proceed to S304.
In S308, under history selection mode, user operation right direction key 20g, judges whether manual input value V is updated to history value H thus.When under history selection mode, user carries out the operation of right direction key 20g (S308: yes), cursor C moves to manual input value V, becomes the state (S309) of the history value H that can change display on manual input value V, proceeds to S304.When user does not operate right direction key 20g under history selection mode (S308: no), proceed to S310.
At S310, under history selection mode, user continues operation electronics index dial 20i, judges whether the selection based on cursor C turns back to manual input value V again from history value H thus.Thus, when user does not operate right direction key 20g and makes cursor C turn back to manual input value V (S310: yes), as manual input value V, again be presented at before entering history selection mode, in the value of manual input value V region display, and become the state (S311) that can change manual input value V, proceed to S304.When user does not operate right direction key 20g and electronics index dial 20i under history selection mode (S310: no), return S308.In addition, when history selection mode is removed and cursor C returns to manual input value V from history value H, be at random set in manual input value in advance which rank display highlighting C.
In the present embodiment, in S301, because manual input value V shows the value of the focal length determined last time, therefore, when user wants to use the focal length value identical with last time, only operation OK button 20c.That is, when user presses OK button 20c under the state that manual input value V shows the focal length determined last time, undertaken by the order of S302, S306, S304, S305, carry out after aftermentioned focal length determines, this subprocess being terminated.
As shown in Figure 4, at the end of this subprocess, enter photograph mode from S203.After forwarding photograph mode to, CPU10 can be used in the focal length value determined in this subprocess, accurately controls the anti-vibration action by hand shaking correction unit 11 pairs of imaging apparatuss 12.In addition, this focal length value can also be attached in the view data of shooting as image information.
Below, the process that S305 mid-focal length is determined is described.In the present embodiment, in 8 memory blocks (conveniently, the address of each memory block being set to address 0 ~ 7) of EEPROM17, temporally sequence order stores the data of history value H.That is, in history value H, last look is stored in address 0, and in history value H, value is the earliest stored in address 7.As history value H, CPU10, the value be stored in address 0 ~ 7 is presented at display part 19 according to the order from new address, on display part, temporally sequence shows history value H thus.
Fig. 7 is the process flow diagram of focal length determination subprocess.First, in S501, judge that whether user is consistent with any one value of history value H by the manual input value V of pressing OK button 20c setting.When any one of manual input value V and history value H is worth inconsistent (S501: no), proceeds to S502, this manual input value V is appended in EEPROM17 as up-to-date historical information.In addition, the number that can show as history value H is limited (8).Therefore, from EEPROM17, the focal length value as historical information is the earliest deleted.After carrying out these process, this subprocess is terminated.
The outline of process when proceeding to S502 from S501 focal length input picture has been shown in (a) of Fig. 9.In addition, in (a) ~ (c) of Fig. 9, for convenience of explanation, as constitution element, display part 19 and manual input value V and history value H are only shown, and each address of the memory block of EEPROM17 and the corresponding relation of history value are shown.In addition, in (a) ~ (c) of Fig. 9, although illustrate the renewal process of history value H, do not need display update process on display part 19, show under posterior focal distance input picture time display update history value H.
In (a) of Fig. 9, the manual input value shown in S305 is the situation of 18.5.As shown in (a) of Fig. 9, any one value of manual input value V and history value H is all inconsistent.Therefore, CPU10 by the history value the earliest that is stored in address 7 (in (a) of Fig. 9,300.0) discarded, each value stored in address 0 ~ 6 is moved 1 address one by one and is stored in address 1 ~ 7, and store manual input value V in address 0.Display part 19 is shown as the state (being appended on 15.0 in (a) of Fig. 9) be appended to as up-to-date historical information by manual input value V in the upper of history value H.In addition, by manual input value V is appended in history value H, historical information number exceedes stated number, therefore, before manual input value V is appended to history value H, the value (in (a) of Fig. 9,300.0) shown in the lowermost position of history value H is shown as the state of deleting from history value H on display part 19.
In S501, when manual input value V is consistent with any one value of history value H (S501: yes), proceed to S503.In S503, judge that whether manual input value V is consistent with the last look of history value H.When the last look of manual input value V and history value H is inconsistent (S503: no), proceed to S504.In S504, value consistent with manual input value in history value H is recorded in EEPROM17 again as last look.After carrying out above process, this subprocess terminates.
In (b) of Fig. 9, show the summary of the process focal length input picture when proceeding to S504 from S503.Here, the manual input value V shown in S305 is the situation of 55.0.As shown in (b) of Fig. 9, the position of value consistent with manual input value V in history value H is the 4th from upper.That is, in EEPROM17, value 55.0 is stored in address 3.Therefore, CPU10 using value 55.0 as last look to address 0 movement while, the value (15.0 in Fig. 9 (b), 21.0,35.0) stored in the address 0 ~ 2 lower than the address 3 storing value 55.0 is moved an address one by one and is stored in address 1 ~ 3.In addition, the value (in (b) of Fig. 9,77.0,135.0,200.0,300.0) stored in higher than the address 3 storing value 55.0 address 4 ~ 7 does not change.Thus, as shown in (b) of Fig. 9, display part 19 is shown as the state that value 55.0 moves to the upper of history value H, surplus value temporally sequence permutation.
In S503, when manual input value V is consistent with the last look of history value H (S503: yes), proceed to S505, under the state maintaining the current state of the history value H recorded in EEPROM17, this subprocess terminates.
(c) of Fig. 9 represents that focal length when proceeding to S505 from S503 inputs the outline of the process picture.Here, the manual input value V shown in S305 is the situation of 15.0.As shown in (c) of Fig. 9, the position of the value consistent with manual input value V is the upper of history value H.Therefore, CPU10 maintains state value 15.0 being stored in address 0 as last look.Thus, as shown in (c) of Fig. 9, value and the order of history value H are not presented on display part 19 with being changed.
As mentioned above, by according to the content of manual input value V temporally sequence rearrange display history value H, easily grasp the value of the focal length of setting in the past.In addition, because the value of setting moves to the upper of history value H, therefore the frequent focal length used is presented at the upper of history value H continuously, and therefore the focal length be accustomed to the use of can be retained in history value H by user.In addition, do not repeat in history value H to show identical value.Therefore, such as, when only carrying out the power on/off of camera 10 not carrying out lens changing, even if do not change the focal length value determined last time and again determine in above-mentioned focal length input processing, focal length value identical in history value H also can not show multiple, and therefore that shows historical information efficiently.
In the above description, owing to only performing focal length input processing when the power supply of camera body 1 is connected, therefore, when changing lens changeable under the state that the power supply of camera body 1 is connected and when manually handling the focal length changing zoom lens when lens changeable is zoom lens, CPU10 can not obtain the information relevant with the focal length after lens changing or after camera lens manual operation.Therefore, the accurate action control based on suitable focus information can not be carried out in camera body 1 side.Therefore, in the present embodiment, further, after the power supply of camera body 1 is connected, can at the setting content of arbitrary moment change focal length.Particularly, as described later, interrupt process is started by pushbutton switch 21.
Fig. 6 is for carrying out the process flow diagram of the interrupt process of this change in present embodiment.As shown in Figure 1, 2, before camera body 1, pushbutton switch 21 is provided with.When accessory is fitted to fuselage interface 22 and carries out rotating operation by user, by scheming the parts such as the spring lock (latch) that do not show, by fitting lockout to camera body 1.When user presses pushbutton switch 21, the locking based on parts such as spring locks is removed, and carries out rotating operation, can unload accessory thus from camera body 1 while pressing pushbutton switch 21 to accessory.As shown in Figure 2, CPU10 is electrically connected with pushbutton switch 21, and can detect the operation of user to pushbutton switch 21.
After being connected by the power supply of camera body 1, when the arbitrary moment presses the button switch 21, proceed to S401.In S401, CPU10 trial obtains the intrinsic information of the accessory installed via fuselage interface 22, and judges whether camera body 1 is provided with interface adapter.When being judged to have installed interface adapter (S401: yes), proceeding to S402, performing the subprocess shown in Fig. 5.Because the contents processing of this subprocess is described above, therefore omit the description.Due to unloaded when therefore accessory does not have an installation fitting on camera body 1 and installed on camera body 1 not there is the accessory of the identifying information of interface adapter time etc., when being judged to be that the accessory be arranged on camera body 1 is not interface adapter (S401: no), this interrupt process is terminated, enters image pickup mode.
Therefore, user utilizes the program determination focal length shown in Fig. 4,5 when power supply is connected after, just can the focal length of change setting by means of only pressing the button switch 21.In addition, when manually changing the focus of lens changeable 3, focal length can be changed similarly.By making pushbutton switch 21 have Trigger Function for changing focal length, focal length can be changed simply in the arbitrary moment, and can not hinder to the function that the various buttons of input part 20 distribute.Thus, suitable focal length value is used can to carry out accurate vibration Restrained Control and the photographed images information creating of imaging apparatus 12.
It is more than the explanation of the embodiment of example of the present invention.Embodiments of the present invention are not limited to the content of above-mentioned explanation, and can carry out various distortion in the scope of technological thought of the present invention.Such as, in above-mentioned explanation, although the description of requiring that user carries out the situation of the input of focus information, but also can require that user carries out the input of the various information relevant with the lens changeable needed for the action control of camera body 1.Thereby, it is possible to carry out the control treatment of the lens properties of the lens changeable be adapted to be mounted within interface adapter in camera body 1 side.In addition, each value focal length input picture shown can be presented on display part 19 to form arbitrarily.
