  The operation of the zoom lens system using the ring operating member will be described with reference to FIGS. 3-1, 3-2 and 7. FIG.

  First, the image pickup apparatus is activated (S100). Details of S100 will be described later using another drawing.

  Next, the operation effective range of the ring operation member and the currently set operation effective range number recorded in the nonvolatile memory 56 are read and associated with the drive range of the zoom lens system (S101). The operation effective range number will be described later.

  The association is performed as illustrated in FIG. The end of the effective operation range is divided into Wide and Tele, and the interval between them is equally divided and assigned to each zoom lens system stop position. Thus, if the ring operation member is operated to the position corresponding to each illustrated zoom lens system stop position, the zoom lens system moves to the corresponding position.

  FIG. 8-2 shows a case where the set operation effective range is narrower than a predetermined warning range. In this case, as shown in the figure, the places where the zoom lens system can be stopped are limited.

  The driving speed of the zoom lens system is determined from the operation speed of the ring operation member and the operation amount corresponding to the zoom lens system stop position of the ring operation member. The speed is adjusted so that the current position of the driving zoom lens system does not deviate from the position of the ring operating member corresponding to the position.

  Next, it is determined whether the menu switch 72 has been pressed (S102). If not, the process moves to S124. The description from S124 will be described later.

  If the menu switch 72 has been pressed, it is displayed on the image display unit 28 (S103). It is determined whether the ring operation member effective range selection has been selected in the menu screen (S104). If not selected, the other selected menu is executed (S105), and the process returns to S102. If selected, a ring operation member operation effective range selection screen (FIG. 5) is displayed on the image display unit 28 (S106). In this screen, the effective operation range recorded in the nonvolatile memory 56 is displayed.

  In this embodiment, three effective ranges are displayed, but it is of course possible to have more or less than this. The user uses the operation unit 74 of the imaging device to select the displayed operation effective range. As a result of the operation, the operation effective range selection frame 502 is moved to enclose the currently selected operation effective range. An operation effective range graph is displayed on the ring operation member operation effective range display unit 504 of a number for which an operation effective range has already been set, and an operable angle is displayed on the operation effective range display unit 505. . This angle is detected by detecting a pulse amount generated by operating the ring operating member. The position where the operation angle is 0 ° is the ring operation member position when the imaging device is activated.

  The operation effective range of the number that has not been set is not displayed in the operation effective range graph in the ring operation member operation effective range display unit 504, and is still displayed by displaying an asterisk (*) in the operation effective range display unit 505. Clarify that it is not set. It is assumed that one operation effective range is always set before the user sets it for the first time. Although it is possible to overwrite the operation effective range setting, it is not possible to erase it, so that it is guaranteed that one operation effective range is recorded.

  Next, it is determined whether a set operation effective range has been selected (S106). When the set operation effective range is selected, first, the selected operation effective range number is recorded in the nonvolatile memory (S108). By recording here, the selected operation effective range is read in the operation effective range reading when the imaging system is activated (S101). Next, the selected operation effective range is associated with the driving range of the zoom lens system (S109). Thereafter, the process returns to the menu switch determination in S102.

  If an unset operation effective range is selected, a ring operation effective range setting screen (FIG. 6-1) is displayed on the image display unit 28 (S110). Next, it is detected whether the ring operation member has been operated (S111). If not operated, it is next detected whether the cancel button 605 has been selected. When cancel is selected, the ring operation effective range setting screen (FIG. 6-1) is deleted, and the process returns to the menu switch determination of S102. If cancel is not selected, the process returns to the ring operation member operation detection in S111. If it is detected that the ring operating member has been operated, it is next detected whether the ring operating member has been operated clockwise as viewed from the user from the initial position (S113).

  Since the effective operation range can be set in the clockwise direction from the initial position, this detection is performed. The range in which the operation effective range can be set is one rotation of the ring operation member. When the operation amount exceeds 360 °, the initial position is set to 0 ° again and the rotation angle is detected. If it is not operated clockwise from the initial position, the operation amount detection returns to S111. When operated, the output pulse from the ring operation member is detected, and the angle is detected from the movement amount of the operation member. The detected angle is graphed and displayed as a ring operation member operation effective range display graph 602.

  Further, this angle is displayed in the ring operation member operation effective angle display portion 603. When the operation amount is larger than the warning amount, a graph is drawn as shown at 606 in FIG. When the operation amount is smaller than the warning amount, a graph of the operation amount is drawn with a color or pattern different from 606, as indicated by reference numeral 607 in FIG. When the operation amount is smaller than the error amount, a graph of the operation amount is drawn with a different color or pattern from 606 and 607 as indicated by 608 in FIG. 6-4. Furthermore, an * mark or the like is displayed on the ring operation member operation effective angle display portion 603 to clearly indicate that the setting cannot be made. The warning amount and error amount will be described later.

  The operation range determination is determined by detecting the OK button 604 (S115). When the operation range setting is not determined, the process returns to the ring operation member operation detection in S111. If the operation range setting is determined, it is next determined whether the operation amount is smaller than the warning amount (S117). The warning amount is an amount by which the set operation amount of the ring operation member is smaller than the number of stop positions of the zoom lens system.

  Next, it is determined whether the operation amount is smaller than the error amount (S118). The error amount is an operation amount that cannot be associated with the zoom lens system stop position. For example, when the operation range setting is determined while the ring operation member is not operated, the operation amount is smaller than the error amount, so the setting error screen is displayed on the image display unit 28 (S121), and the operation of S111 Return to detection.

  When the operation amount is larger than the error amount, a warning screen is displayed on the image display unit 28 (S120). This warning screen also displays the number of stop positions of the zoom lens system. In order to reduce the number of stop positions of the zoom lens system, there are a case where the stop position of the zoom lens system is automatically thinned and a case where the user thins out a zoom point which is not frequently used by the user. Since the user can select the zoom lens stop position to be thinned out by himself, it is possible to leave many zoom lens system stop points on the wide-angle side or leave many zoom lens stop points on the telephoto side.

  Next, it is determined whether resetting is selected in the warning screen (S121). If resetting is selected, the process returns to the operation detection in S111. When the resetting is not selected, the operation amount is reflected in the area of the operation effective range number selected in S107 and recorded in the nonvolatile memory 56 (S122).

  Next, after the selected operation effective range is associated with the driving range of the zoom lens system, the menu screen is cleared and the process returns to S102 (S123). If it is not detected in S102 that the menu switch is pressed, it is next detected whether the ring operation member is operated (S124). If the ring operation member has not been operated, the process returns to the menu switch determination in S102. When it is detected that the ring operation member is operated, the zoom operation bar 702 is displayed on the image display unit 28 (S125).

  Next, it is detected from the output pulse information of the ring operation member in which rotation direction the ring operation member is operated (S126). If it is operated clockwise as viewed from the user, it is determined whether the current zoom lens system position is the Tele end which is the maximum field angle position (S127). If the current position is the Tele end, the process returns to the menu switch determination in S102. If the current position is not at the Tele end, the zoom lens system starts to be driven in the Tele direction (S128). If it is operated counterclockwise as viewed from the user, it is determined whether the current zoom lens system position is the Wide end, which is the minimum field angle position (S129).

  When the current position is the Wide end, the process returns to the menu switch determination in S102. If the current position is not the Wide end, driving is started with the zoom lens system facing the Wide end (S130). Next, the operation amount of the ring operation member is detected (S131). The detected operation amount is converted into a zoom lens system position and displayed on the zoom operation bar 702 (S132).

  The zoom bar for the operation amount is displayed as indicated by 703 in FIG. Next, the current zoom lens system position is displayed on the zoom operation bar 702 (S134). The current zoom lens system position display is displayed as indicated by 704 in FIG. By displaying the operation amount display of the ring operation member separately from the current zoom lens system position, even if the ring operation member is operated at a higher speed than the drive of the zoom lens system, it can be operated to any zoom lens system position. You can know if you are.

  Next, it is determined whether or not the operation has been performed in the direction opposite to the direction operated so far (S134).

  If it has been operated in the direction opposite to the direction operated until then, the amount of the next operation is detected (S135). The detected operation amount is converted into the corresponding zoom lens system position and displayed on the zoom operation bar 702 (S136). Next, it is detected whether further operation has been performed from the current zoom lens system position.

  That is, the position obtained by converting the operation amount into the zoom lens system position is the Wide side if it has been moved in the Tele direction from the current zoom lens system position, and the Tele side if it has been moved in the Wide direction. Is determined (S137). If the operation amount of the ring operation member has been operated from the current zoom lens system position, the zoom lens system is stopped (S138).

  Next, the driving is started in the direction opposite to the driving direction until that time (S139). Thereafter, the process returns to the operation amount detection in S131. When the operation amount of the ring operation member has not been operated from the current zoom lens system position, the operation amount detection returns to S131.

  If it is operated in the same direction as that operated until then, it is determined whether or not the ring operation member is continuously operated (S140).

  If it is detected that the ring continues to be operated, it is next detected whether the ring operating member has been operated to the end of the effective operation range (S141). When the operation is not performed to the end of the effective range, the process returns to the operation amount detection in S131. If it is operated to the end of the effective operation range, it is stopped at the Tele end when it is driven in the Tele direction, and is stopped at the Wide end when it is driven in the Wide direction (S142). When it is detected that the operation of the ring operation member is stopped, the zoom operation is stopped at the zoom lens system stop position corresponding to the operation amount of the ring operation member (S142). Thereafter, the process returns to the menu switch determination in S102.

  FIG. 4 is a detailed flowchart for the activation of the imaging apparatus in S100 of FIGS. 3-1 and 3-2.

  Upon power-on such as battery replacement, the system control circuit 50 initializes flags, control variables, and the like (S201), and initializes the image display on the image display unit 28 to an OFF state (S202).

  The system control circuit 50 determines the setting position of the mode dial 60, and if the mode dial 60 is set to power OFF (S203), the display of each display unit is changed to the end state, and the barrier of the protection unit 102 is changed. Is closed to protect the imaging unit, and necessary parameters, setting values, and setting modes including flags and control variables are recorded in the nonvolatile memory 56, and each part of the image processing apparatus 100 including the image display unit 28 by the power control unit 80. After performing a predetermined end process such as shutting off unnecessary power (S205), the process returns to S203.

  If the mode dial 60 is set to the shooting mode (S203), the process proceeds to S206.

  If the mode dial 60 is set to another mode (S203), the system control circuit 50 executes a process corresponding to the selected mode (S204), and returns to S203 when the process is completed.

  The system control circuit 50 determines whether or not there is a problem in the operation of the image processing apparatus 100 with respect to the remaining capacity or operation status of the power supply 86 configured by a battery or the like by the power supply control means 80 (S206).
