  Next, the operation of the image processing apparatus 100 according to the present embodiment will be described with reference to FIGS.

  FIG. 2 is a flowchart of the main routine of the image processing apparatus 100 according to the present embodiment.

  First, in step S201, the system control circuit 119 initializes a flag, a control variable, and the like by turning on power such as battery replacement, and in the next step S202, sets the image display of the image display unit 111 to an OFF state. Next, in step S203, the system control circuit 119 determines the set position of the mode dial 123. If it is determined that the mode dial 123 is set to power OFF, the process proceeds to step S205 to perform a predetermined end process, and then returns to step S203.

  Specifically, the predetermined end process in step S205 needs to change the display of each display unit to the end state, close the barrier of the protection unit 139 to protect the imaging unit, and include a flag, a control variable, and the like. This is a process of recording various parameters, setting values, and setting modes in the nonvolatile memory 122 and shutting off unnecessary power sources of the respective parts of the image processing apparatus 100 including the image display unit 111 by the power control unit 130.

  If it is determined in step S203 that the mode dial 123 is set to another mode, the process proceeds to step S204, and the system control circuit 119 executes processing according to the selected mode. The process returns to step S203.

  Further, when it is determined in step S203 that the mode dial 123 is set to the shooting mode, the process proceeds to step S206, and the system control circuit 119 is a power supply unit configured by a battery or the like by the power supply control unit 130. It is determined whether or not the remaining capacity or operation status of 133 has a problem in the operation of the image processing apparatus 100 (whether or not the battery is OK). If it is determined that there is a problem, the process proceeds to step S208, where a predetermined warning is displayed by an image or sound using the display unit 121, and then the process returns to step S203.

  On the other hand, if it is determined in step S206 that there is no problem with the power supply means 133, the process proceeds to the next step S207, and the system control circuit 119 determines that the operation state of the recording medium 200 or 210 is the operation of the image processing apparatus 100. In particular, it is determined whether or not there is a problem in the recording / reproducing operation of the image data with respect to the recording media 200 and 210 (whether or not the recording medium is OK). If it is determined that there is a problem with the operation state of the recording medium 200 or 210, the process proceeds to step S208, and a predetermined warning is displayed by an image or sound using the display unit 121, and then the step S203 is performed. Return to.

  On the other hand, if it is determined in step S207 that there is no problem in the operation state of the recording medium 200 or 210, the process proceeds to the next step S209, and various types of the image processing apparatus 100 are displayed using images and sounds using the display unit 121. Displays the setting status.

  If the image display of the image display unit 111 is ON, the image display unit 111 is also used to display various setting states of the image processing apparatus 100 using images and sounds.

  Next, proceeding to step S210, the system control circuit 119 sets the image display of the image display unit 111 to the ON state, and after setting the captured image data to the through display state in which the captured image data is sequentially displayed in the next step S211. The process proceeds to the next step S212.

  In the through display state in step S211, data sequentially written in the image display memory 109 via the image sensor 104, the A / D converter 105, the image processing circuit 107, and the memory control circuit 108 are stored in the memory control circuit 108. The electronic finder function is realized by sequentially displaying on the image display unit 111 via the D / A converter 110.

  In step S212, the system control circuit 119 determines whether or not the macro ON / OFF switch 127 has been pressed. If it is determined that the macro ON / OFF switch 127 has been pressed, the process proceeds to step S213, and the macro shooting mode (in which shooting is performed while focusing on a subject closer to the normal shooting mode (first shooting mode)). After performing the (second shooting mode) process, the process proceeds to the next step S214.

  Details of the macro shooting mode processing in step S213 will be described later with reference to FIGS.

  On the other hand, if it is determined in step S212 that the macro ON / OFF switch 127 is not pressed, the process skips step S213 and proceeds to step S214.

  In step S214, the state of the shutter switches SW1 and SW2 is determined. If it is determined that the shutter switches SW1 and SW2 are pressed, the process proceeds to step S215 to perform shooting / recording processing, and then returns to step S214. .

  Note that details of the photographing / recording process in step S215 are widely known and will not be particularly described here.

  On the other hand, if it is determined in step S214 that the shutter switches SW1 and SW2 are not pressed, the process returns to step S203.

  Next, the macro shooting mode processing in step S213 in FIG. 2 will be described with reference to FIGS.

  FIG. 3 shows a super macro shooting mode (third shooting mode) area / normal shooting in which shooting is performed while focusing on a subject that is closer than the macro shooting mode in which shooting is performed while focusing on a subject that is closer than in the normal shooting mode. It is a figure explaining the ranging range in the macro photography mode (2nd photography mode) area | region / normal photography mode (1st photography mode) area | region which focuses and shoots the subject which approached from the mode.

  The super macro shooting mode area is 3 cm to 30 cm, the macro shooting mode area is 30 cm to 50 cm, and the normal shooting mode area is 50 cm to infinity. Of course, there is no problem even if the ranging range is changed in accordance with the characteristics of the camera.

  FIG. 4 is a diagram for explaining areas recorded in the super macro shooting mode and areas recorded in the non-super macro shooting mode (macro shooting mode and normal shooting mode) in the image sensor 104. , 104 is an image sensor, 401 is an area recorded in the super macro shooting mode, and 402 is an area recorded in the non-super macro shooting mode.

  In the super macro shooting mode, an image signal in a smaller area is recorded than in the non-super macro shooting mode (normal shooting mode and macro shooting mode). When focusing on the closest subject, vignetting that prevents light from entering the periphery of the image sensor 104 occurs. Therefore, only the image signal of the central portion where no vignetting occurs is recorded among the image signals of the image sensor 104. The electronic viewfinder display also displays only images in a range where no vignetting occurs.

  The function of enlarging and displaying a part of the image sensor 104 is widely known as electronic zoom. A method of recording only an image signal of a part of the image sensor 104 is also widely known together with the electronic zoom. A range where no vignetting occurs in the image sensor 104 is stored in the nonvolatile memory 122 in advance.

  FIG. 5 is a diagram for explaining the relationship between the zoom position and the vignetting. In FIG. 5, the vignetting is large on the wide-angle side (W) and the telephoto side (T).

  Assume that the zoom position of the zoom lens 101 is a position indicated by a black circle in FIG. At this time, if the super macro shooting mode is set by the user, the zoom lens 101 is moved to a position indicated by a black circle in FIG. A range where the vignetting is small is stored in advance in the nonvolatile memory 122 in accordance with the characteristics of the zoom lens 101. The system control circuit 119 moves the zoom lens 101 to the zoom position closest to the current zoom position in the range where the vignetting is small stored in the nonvolatile memory 122.

  FIG. 6 is a flowchart showing the flow of the macro shooting mode processing operation in step S213 of FIG.

  First, in step S601, the system control circuit 119 checks the state of the macro flag in order to determine the current macro shooting mode setting. If the macro flag is OFF, the ranging range is normal. If the macro flag is macro, the ranging range is macro. If the macro flag is super macro, the ranging range. Is a super macro.

  If it is determined in step S601 that the macro flag is OFF, the process proceeds to step S602 to perform processing for setting the distance measurement range to macro. That is, the system control circuit 119 sets the macro flag to macro, moves the focus lens 102 to the macro position in the next step S603, and then proceeds to step S608. When the focus lens 102 is moved to the macro position, it may be moved in accordance with the characteristics of the focus lens 102 lens. For example, the focus lens 102 may be moved so as to focus on a subject at a distance of 40 cm from the tip of the focus lens 102.

  If it is determined in step S601 that the macro flag is macro, the process advances to step S604 to perform processing for setting the distance measurement range to normal. That is, the system control circuit 119 sets the macro flag to OFF in step S604, returns the focus lens 102 to the normal position in the next step S605, and then proceeds to step S608. When the focus lens 102 is returned to the normal position, it may be moved in accordance with the characteristics of the focus lens 102. For example, it may move so as to focus on a subject at infinity.

  Further, if it is determined in step S601 that the macro flag is a super macro, the process proceeds to step S606 to perform processing for normalizing the distance measurement range. That is, the system control circuit 119 turns off the macro flag in step S606, performs super macro cancellation processing in the next step S607, and then ends this processing operation.

  Details of the super macro cancellation processing in step S607 will be described later with reference to FIG.

  In step S608, the system control circuit 119 determines whether or not the macro ON / OFF switch 127 has been released (OFF). If it is determined that the macro ON / OFF switch 127 has been released, this processing operation is terminated.

  On the other hand, if it is determined in step S608 that the macro ON / OFF switch 127 is kept pressed, the process proceeds to step S609.

  In step S609, it is determined whether or not the macro ON / OFF switch 127 has been pressed for a predetermined time or longer. If it is determined that the macro ON / OFF switch 127 has not been pressed and pressed for a predetermined time or longer, the process returns to step S608. The predetermined time or longer may be any time. For example, it may be 1 second.

  On the other hand, if it is determined in step S609 that the macro ON / OFF switch 127 has been pressed for a predetermined time or longer, the process proceeds to step S610 to set the macro flag to the super macro, and then to the next step S611. Then, after performing the super macro process for setting the distance measurement range to the super macro, this processing operation is terminated.

  Details of the super macro process in step S611 will be described later with reference to FIG.

  As described above, when the super macro shooting mode is set, since it is necessary to press and hold the macro ON / OFF switch 127, it is possible to prevent the super macro shooting mode from being set by mistake.

  On the other hand, when canceling the super macro shooting mode, since the super macro shooting mode is canceled when the macro ON / OFF switch 127 is pressed, it is possible to immediately return to the setting of the normal shooting mode. Further, when setting a macro shooting mode without electronic zoom processing, it is possible to set the macro shooting mode without pressing the macro ON / OFF switch 127 for a long time.

  FIG. 7 is a flowchart showing the flow of the super macro processing operation in step S611 in FIG.

  First, in step S701, the system control circuit 119 sequentially displays, on the image display unit 111, only a portion where vignetting does not occur in the captured image data by using the electronic zoom. Next, in step S702, the system control circuit 119 acquires the current zoom position, and in the next step S703, determines whether or not the current zoom position is a zoom position where vignetting is large. If it is determined that the current zoom position is not a zoom position with a large amount of vignetting, this processing operation ends.

  On the other hand, if it is determined in step S703 that the current zoom position is a zoom position with a large amount of vignetting, the process proceeds to step S704, and the zoom lens 101 is positioned closest to the current zoom position in a region with a small amount of vignetting. To move. Next, in step S705, the system control circuit 119 ends the processing operation after moving the focus lens 102 to the close side, that is, to the super macro position.

  In step S705, when the focus lens 102 is moved to the closest side, the focus lens 102 may be moved in accordance with the characteristics of the focus lens 102 lens. For example, the focus lens 102 may be moved so as to focus on a subject at a distance of 5 cm from the tip of the focus lens 102.

  FIG. 8 is a flowchart showing the flow of the super macro cancellation processing operation in step S607 of FIG.

  First, in step S801, the system control circuit 119 returns the focus lens 102 to the normal position. By returning the focus lens 102 to the normal position, vignetting in the periphery of the image sensor 104 does not occur. In the next step S802, the system control circuit 119 ends the processing operation after canceling the electronic zoom. To do.

  FIG. 9 is a diagram illustrating a display example of a zoom bar displayed on the image display unit 111 in the image processing apparatus 100 according to the present embodiment, where W is a wide end (wide angle) and T is a tele end (telephoto). ). The zoom bar is displayed to indicate the current zoom position.

  9A shows a display screen of the image display unit 111 displaying a zoom bar, and FIG. 9B shows a display example of the zoom bar when the normal shooting mode is set, that is, the zoom lens 101 near the tele end. FIG. 9C shows a display example of the zoom bar when the macro shooting mode is set from the state of FIG. 9B, respectively.

  When the zoom lever 129 is operated, the system control circuit 119 drives the zoom lens 101 and displays a zoom bar as shown in FIG. 9A on the image display unit 111.

  Assume that the zoom bar as shown in FIG. 9B is displayed on the image display unit 111 in the state where the macro shooting mode is set to OFF. When the macro shooting mode is set to ON in this state, the optical zoom (zoom lens 101) moves to the most telephoto (tele end) side position in the range where vignetting is unlikely to occur, and FIG. A zoom bar as shown in FIG.

  In FIG. 9C, the wide-angle side is displayed as the tele end, and the telephoto side is displayed as the wide end in the range where vignetting is difficult.

  When the macro shooting mode is set to ON in the state of FIG. 9B, the optical zoom (zoom lens 101) moves to the telephoto side most in the range where vignetting is difficult to occur, and thus is displayed as a tele end.

  When the zoom lever 129 is operated when the macro shooting mode is set, the system control circuit 119 permits the zoom lens 101 to be driven only in a range where vignetting is unlikely to occur.

  FIG. 10 is a diagram showing a display example of a zoom bar displayed on the image display unit 111. In FIG. 10, W represents the wide end (wide angle) and T represents the tele end (telephoto).

  FIG. 10A shows an example of zoom bar display when the normal shooting mode is set, and FIG. 10B shows an example of zoom bar display when the macro shooting mode is set from the state of FIG. Each is shown.

  Now, it is assumed that a zoom bar as shown in FIG. 10A is displayed on the image display unit 111 with the macro shooting mode set to OFF. When the macro shooting mode setting is turned on in this state, a zoom bar as shown in FIG. 10B is displayed on the image display unit 111.

  In the display example of the zoom bar shown in FIG. 10B, ▽ represents a range where vignetting is difficult to occur. In the macro shooting mode, the optical zoom (zoom lens 101) moves only in a range where vignetting is unlikely to occur. The range in which the optical zoom (zoom lens 101) does not move in the macro shooting mode (the range in which vignetting is large) expresses that the optical zoom (zoom lens 101) does not move, for example, by filling in yellow.

  In the present embodiment, the range in which the optical zoom (the zoom lens 101) does not move is filled in yellow in the macro shooting mode, but any color may be used. For example, any color can be used as long as it is an identifiable color such as blue, red, and green. Further, instead of painting with colors, a stripe pattern or the like may be used.

  In the present embodiment, the image display unit 111 is described as being always turned on. However, the image display on / off switch 126 is configured so that the image display unit 111 can be turned on / off. It doesn't matter. Further, the macro shooting mode may be canceled when the image display unit 111 is turned off, and the macro shooting mode setting may not be permitted when the image display unit 111 is turned off.

  In addition, when the image display unit 111 is OFF, the electronic finder and the zoom bar are not displayed, and thus the user does not know that the macro shooting mode is set. For this reason, when the image display unit 111 is OFF, it is possible to prevent an erroneous operation by not performing macro photography.
