The second flash memory 124 is a flash memory area inside the camera system controller 125 in this embodiment, but is not limited to this, and may be provided outside the camera system controller 125. In other words, the second flash memory 124 may be provided outside the camera system controller 125 or may be incorporated inside the camera system controller 125.

  The camera system controller 125 can acquire the exposure, color difference, and focus evaluation values generated by the camera signal processing circuit 121 and read various parameters stored in the second flash memory 124.

  The camera system controller 125 reads various key switches of the camera unit 102 by the operation key detection circuit 126, and switches the control contents according to the result.

Data 3) are different from each other. In this embodiment, the optical data 2 and 3 recorded in the external memory 132 are new data obtained by updating the optical data 1 recorded in the first flash memory 117. In other words, the optical data recorded in the external memory 132 in this embodiment is an update of the optical data recorded in the first flash memory 117.

  Next, the flowchart of the control method of the camera unit 102 according to the embodiment of the present invention shown in FIG. 5 will be described in detail. In the following flowchart, S means a step.

  First, in S101, an external memory is inserted into the camera unit 102.

  Next, when the lens unit 101 is attached to the camera unit 102 in S102, the camera system controller 125 confirms the attachment of the lens unit 101 by the lens unit detection circuit 134.

  When it is confirmed that the lens unit 101 is mounted, the camera system controller 125 starts communication with the lens system controller 116.

  In S103, the lens system controller 116 transmits the accessory unique identification data described in the first flash memory 117 to the camera system controller 125 by communication.

  In S104, the camera system controller 125 reads the accessory unique identification data recorded in the external memory 132, and compares it with the accessory unique identification data transmitted in S103.

  Here, if the accessory unique identification data recorded in the external memory 132 records the accessory unique identification data of the lens unit 101 mounted as shown in FIG. 2, the process proceeds to the next step S106.

  On the other hand, if the accessory unique identification data of the mounted lens unit 101 is not yet recorded in the external memory 132 as shown in FIG. 3A, the accessory unique identification data is stored in the external memory 132 in S105. Write. In other words, when the lens unit 101 is attached to the camera unit 102, the camera system controller 125 first acquires unique identification data for identifying the lens unit 101 from the lens unit 101. If there is no unique identification data in the external memory 132, the unique identification data is recorded in the external memory 132.

  In step S <b> 106, the camera system controller 125 confirms whether the optical data of the mounted lens unit 101 is recorded in the external memory 132.

  Here, as shown in FIG. 3B, when the optical data of the mounted lens unit 101 is not written in the external memory 132, the process proceeds to S121, and the first flash memory 117 in the lens unit 101 is obtained. To use the optical data 1 recorded in

  In S122, the camera system controller 125 determines whether an instruction for a shooting preparation operation or a shooting start operation by a shooting SW (not shown) has been received. In this embodiment, it is determined that there is an instruction to start a shooting preparation operation when a shooting SW (not shown) is pressed halfway (shooting SW ON), and the shooting SW (not shown) is fully pressed (shooting SW). ON), it is determined that there is an instruction to start the shooting start operation. When the photographing SW is turned on in S122, the camera system controller 125 reads the optical data 1 recorded in the flash memory 117 in the lens unit 101 by communication in S123. In step S124, the camera system controller 125 controls the lens unit 101 to start a shooting sequence. In other words, when the optical data of the mounted lens unit 101 is not recorded in the external memory 132, the optical data 1 is acquired from the flash memory 117 in the lens unit 101, and the lens unit 101 is stored in the external memory 132. Control.

  On the other hand, if the optical data of the lens unit 101 mounted as shown in FIG. 2 is written in the external memory 132 in S106, the process proceeds to the next S107.

  In S107, the setting for selecting the optical data to be used is the setting for the user selection mode using the optical data designated by the user through the input unit 133, or the setting for the auto mode in which the camera system controller 125 selects the optical data. Judgment is made. If the setting for selecting optical data to be used is the user selection mode, the process proceeds to S130 (FIG. 6), and if the setting is the auto mode, the process proceeds to S108.

  FIG. 5 illustrates a case where the setting for selecting the optical data to be used is the auto mode (the mode selected by the camera system controller 125). The user selection mode will be described later with reference to FIG.

  At S108, camera system controller 125 uses which one of optical data 2, optical data 3, and optical data 1 recorded in first flash memory 117 in external memory 132 shown in FIG. select.

  At the time of this selection, the camera system controller 125 determines optical data that can be handled by the camera unit 102. In the present embodiment, a plurality of pieces of information (optical data 2 and optical data 3) relating to the lens unit 101 are recorded in the external memory 132 as shown in FIG. The first flash memory 117 stores one piece of information (optical data 1) related to the lens unit 101. The camera system controller 125 selects a plurality of pieces of information (optical data 1, optical data 2, and optical data 3) regarding the lens unit 101 to use information corresponding to the camera unit 102.

  Here, a case (S109 to S118) in which the optical data 2 is selected will be described. The same sequence applies to the case where the optical data 3 is selected (S119, S120, S110 to S118). Further, the optical data 1 has the same sequence as when the process proceeds from step S106 to step S121.

  In S109, the camera system controller 125 controls to use the selected optical data 2.

  Next, in S110, it is determined whether the optical data 2 can be recorded with the remaining capacity of the second flash memory in the camera system controller 125.

  If this is possible (Y in S110), in S111, the camera system controller 125 further selects whether or not to read optical data from the internal second flash memory 124. On the other hand, if recording is impossible (N in S110), it is determined in S117 whether or not an instruction for a shooting preparation operation or a shooting start operation by a shooting SW (not shown) has been accepted. If it is determined in S 117 that the instruction has been received, the camera system controller 125 directly reads the optical data 2 from the external memory 132. In other words, when the free capacity of the second flash memory 124 is equal to or less than the predetermined amount, the optical data 2 is directly acquired from the external memory 132.

  In this selection, the camera system controller 125 makes a determination in consideration of the capacity of the second flash memory 124, the communication speed of the external memory 132, the bus usage status, and the like.

  When the camera system controller 125 determines to read the optical data 2 from the second flash memory 124 (Y in S111), the optical data 2 is obtained from the external memory 132 in S112 as shown in FIG. Transfer to the second flash memory 124. In other words, when the free capacity of the second flash memory 124 is larger than the predetermined amount, the optical data 2 is transferred from the external memory 132 to the second flash memory 124.

  In S113, the camera system controller 125 determines whether an instruction for a shooting preparation operation or a shooting start operation by a shooting SW (not shown) is received during transfer of the optical data 2. When the transfer of the optical data 2 is completed without accepting the instruction in S114, the camera system controller 125 stands by until an instruction for a photographing preparation operation or a photographing start operation is given in S115. The state of the second flash memory when the transfer of the optical data 2 is completed is the state of FIG.

  If there is an instruction for a shooting preparation operation or a shooting start operation in S115 (Y in S115), the camera system controller 125 reads the optical data 2 from the second flash memory 124 in S116. In step S124, the lens unit 101 is controlled to start a shooting sequence.

  On the other hand, if there is an instruction for the shooting preparation operation or shooting start operation during transfer of the optical data 2 in S113 (N in S113), the transfer is interrupted, and the camera system controller 125 in S118. The optical data 2 is read directly from the external memory 132. In step S124, the lens unit 101 is controlled to start a shooting sequence. In other words, if there is an instruction for a shooting preparation operation or a shooting start operation while the optical data is being transferred to the second flash memory 124, the transfer is interrupted and the optical data 2 is transferred from the external memory 132. get.

  In S113, when an instruction for a shooting preparation operation or a shooting start operation is given during transfer of optical data (N in S113), the reading destination of the optical data is not limited to the external memory 132. For example, as shown in FIGS. 7 and 8, the camera system controller 125 may read the optical data 1 recorded in the flash memory 117 in the lens unit 101 by communication as a reading destination of the optical data. Good. In other words, if there is an instruction for a shooting preparation operation or a shooting start operation while transferring the optical data 2 to the second flash memory 124, the transfer is interrupted and the optical data 1 is sent from the lens unit 101. You may control to acquire.

  Next, steps after S130 when the user selection mode is set in S107 of FIG. 5 (N of S107) will be described with reference to FIG.

  If the user selection mode is set in S107, the optical data input by the user from the input unit 133 in advance is selected.

  When the optical data 2 recorded in the external memory 132 is selected, the camera system controller 125 determines in S131 whether the camera unit 102 corresponds to the selected optical data. Similarly, when the optical data 3 recorded in the external memory 132 is selected, the camera system controller 125 determines whether the camera unit 102 corresponds to the selected optical data in S132.

  In S131 and S132, if not supported, the camera system controller 125 controls to select the optical data 1 recorded in the flash memory 117 in the lens unit 101 in S121.

  Since the sequence after this is the same as described above, the description thereof is omitted.

  Next, erasing of data recorded in the external memory 132 of the present invention will be described.

  When erasing the image data recorded in the external memory 132 from the camera unit 102, the accessory unique identification data area and the accessory optical data area are not erased, but only the image data area is erased. As described above, when erasing the image data recorded in the external memory 132, the camera system controller 125 erases only the image data and leaves information on the lens unit that has been attached without erasing. Control as follows.
