[0083] 而且,照相机主体1侧的第一微型计算机3和电池组2侧的第二微型计算机7在电池认证通信状态ST4中反复重复共8个"装置侧和电池侧共同具有的信息",直至通信结束(步骤SA35〜步骤SA36、步骤SB33〜步骤SB34)。 [0083] Also, the first microcomputer 3 of the camera body 1 side and the battery pack 2 side of the second microcomputer 7 of the battery authentication communication state ST4, repeating a total of eight "device side and the battery side commonly have" until the end of communication (step SA35~ step SA36, step SB33~ step SB34).

[0084] 接着,照相机主体1侧的第一微型计算机3读出保存在照相机主体1侧的非易失性存储器5中的共同信息,与从电池组2侧的第二微型计算机7得到的信息进行比较(步骤SA37)。 [0084] Next, the first microcomputer 3 of the camera body 1 side readout stored in a side of the camera body of the non-volatile memory 5 together information from two sides of the battery pack and the second microcomputer 7 of the information obtained (step SA37).

[0085] 而且,照相机主体1侧的第一微型计算机3在两个信息一致时判断为是正品电池, 在非易失性存储器5中存储表示"电池认证结束"和表示"插入的电池为正品"的信息(步骤SA38)。 [0085] Also, the first microcomputer 3 of the camera body 1 side in the two information coincide judged to be genuine battery, in the non-volatile memory 5, that "battery authentication end" and that "the inserted battery is genuine "The information (step SA38). 然后,变成"电池剩余电量显示通常通信状态"ST2,只进行"电池剩余电量修正值"的通信。 Then, into a "battery residual quantity display ordinary communication state" ST2, only "battery residual quantity correction value" of communication.

[0086] 而且,照相机主体1侧的第一微型计算机3在两个信息不一致时判断为是假冒电池,然后在液晶显示部4上显示"当前插入的电池为假冒电池,请使用正品电池"的信息,同时在非易失性存储器5中存储表示"电池认证结束"的信息和表示"插入的电池不是正品" 的信息,经过一定时间后,将照相机主体1的电源断开(步骤SA39)。 [0086] Also, the first microcomputer 3 of the camera body 1 side judges when the two inconsistent information to be counterfeit batteries, and then displayed on the liquid crystal display unit 4 "counterfeit battery currently inserted battery, please use genuine battery" information while in the non-volatile memory 5, that "battery authentication End" message and indicates "battery inserted is not genuine" message after a certain period of time, disconnect the power supply of the camera body 1 (step SA39).

[0087] 在该摄像机100中,由照相机主体1侧的第一微型计算机3和电池组2侧的第二微型计算机7执行图3的流程所示的处理,如图4(A)所示的时序所示,当装置主体l的电源接通时,首先,经由电池剩余电量显示初始通信状态ST1变成电池剩余电量显示通常通信状态ST2,最初,在液晶显示部4上显示电池的剩余可使用时间,然后,交替切换电池认证通信状态ST4和电池剩余电量显示通常通信状态ST2,当认证处理结束时,反复进行电池剩余电量显示通常通信状态ST2,更新电池剩余电量显示的内容。 [0087] In the video camera 100, 3 and the second microcomputer 7 of the battery pack 2 side are executed by the first microcomputer in the camera body 1 side of the flow shown in FIG. 3 process, as shown in Figure 4 (A) of timing, when the apparatus main body l of the power is turned on, first of all, through the battery residual quantity display initial communication state ST1 into the battery residual quantity display ordinary communication state ST2, initially, on the liquid crystal display unit 4 displays the remaining battery use time, and then, alternately switching the battery authentication communication state ST4 and the battery residual quantity display ordinary communication state ST2, when the authentication process is finished, repeatedly battery residual quantity display ordinary communication state ST2, update the battery residual quantity display content.

[0088] 这里,如图4中(B)所示的时序所示的在最先进行电池认证的现有电池认证方法中,与如图4中(C)所示的时序所示的现有的仅仅进行电池剩余电量显示的情况相比,电池的剩余可使用时间比最初显示的时间仅慢电池认证通信状态ST4的时间,但是在该摄像机100中,首先进行电池剩余电量显示,然后进行认证处理,所以与仅仅进行电池剩余电量显示的情况相比,电池的剩余可使用时间不比最初显示的时间慢。 [0088] Here, as shown in FIG. 4 (B) shown in the timing of conventional battery authentication method of first authentication in the battery, and FIG. 4 (C) shown in the timing shown in the conventional compared with the case only battery residual quantity display of remaining battery time than initially displayed using only battery authentication communication state ST4 slow time, but the camera 100, first battery residual quantity display, then authentication treatment, as compared with the case only battery residual quantity display of remaining battery time slower than the time initially displayed.

[0089] S卩,在采用了本发明的摄像机100中,最初仅仅进行电池剩余电量显示处理,在液晶显示部4上出现电池的剩余可使用时间后进行电池认证处理,所以到开始出现电池的剩余可使用时间的时间即使追加了电池认证处理,但对用户来说也没有改变,有价值的电池剩余电量显示的功能也不会因为电池认证处理而受损。 [0089] S Jie, in the present invention uses a video camera 100, initially only battery residual quantity display processing, after the battery authentication process appears on the LCD display 4 battery time remaining, so to begin a battery of Remaining time of time even if the additional battery authentication process, but did not change for users valuable battery residual quantity display function will not be damaged because the battery authentication process.

[0090] 这样,在采用了本发明的摄像机100中,即使进行电池认证,作为用户的直接价值的电池的剩余可使用时间也不会慢于最初显示的时间。 [0090] Thus, in the present invention uses a video camera 100, even if battery authentication, as a direct user value of remaining battery time will not be slower than the time initially displayed.

[0091] 另外,在该摄像机100中,与电池剩余电量显示并行地进行电池认证,所以不可能使用不是正品的粗劣的电池,可以防止使用非正品的电池而导致装置主体1的破损等。 [0091] In addition, the video camera 100, and the battery residual quantity display battery authentication is performed in parallel, it is impossible to use coarse battery is not genuine, it can prevent the use of non-genuine batteries and lead to breakage of the apparatus body 1 and the like. [0092] 此外,在该摄像机100中,电池剩余电量显示和电池认证处理两者都是使用照相机主体1侧的第一微型计算机3和电池组2侧的第二微型计算机7的通信系统,通过分时处理进行,所以只需要一个系统的通信线即可,可以削减硬件的成本。 [0092] In addition, in 100, the processing of both the camcorder battery authentication battery residual quantity display and are using the camera 1 side of the body of the first microcomputer 3 and the battery pack 2 side of the second micro-computer communication system 7 through sharing processing, so only one communication line can system, the hardware cost can be reduced.

[0093] 此外,在该摄像机100中,在相同系统内进行电池剩余电量显示处理和电池认证处理,从而通信驱动器是一个系统即可,可以削减软件的开发成本。 [0093] In addition, the video camera 100, in the same system, the battery residual quantity display processing and the battery authentication process, which is a system of communication can drive, can reduce software development costs.

[0094] 此外,在该摄像机100中,通过分割电池认证处理,在电池剩余电量显示处理的间 [0094] In addition, the video camera 100, by dividing the battery authentication process between the battery residual quantity display processing

歇时进行,从而制造粗劣电池的厂家等怀有恶意的人难以破解认证方法。 When break, to produce poor battery manufacturers and other malicious people find it difficult to crack the authentication method.

[0095] 此外,在该摄像机100中,因为电池认证处理分开进行,所以即使不使用高性能微 [0095] In addition, in the video camera 100, since battery authentication processing performed separately, even if does not use high-performance micro-

型计算机也可以进行电池认证,所以削减了成本。 Computer also can be battery authentication, so cut costs.

[0096] 此外,在该摄像机100中,因为电池认证处理分开进行,所以即使不是高速使用微型计算机也可以进行电池认证,所以节省了电力消耗。 [0096] In addition, in the video camera 100, since battery authentication processing performed separately, so even if the use of the microcomputer is not high-speed battery authentication can be performed, thus saving power consumption.

[0097] 此外,在该摄像机100中,因为保存了认证处理结果,所以第二次以后的电源接通 [0097] In addition, in the video camera 100, since the authentication processing results saved, so the second and subsequent power-on

时开始,可以专门进行电池剩余电量显示处理,保护对用户的直接价值。 Initially, it can display the remaining battery power devoted to treatment, protection of direct value to the user.

[0098] 此外,因为电池认证后可以马上使用摄像机100,因此,尤其是在这种摄像机100 [0098] Furthermore, since battery authentication can be used immediately after the video camera 100, and therefore, especially in this video camera 100

或数码照相机这样的摄像装置中,可以縮短更换电池时的时间,减少错过摄像时机的可能, Or a digital camera this imaging device, it can shorten the time to replace the battery, reducing the possibility of missed opportunity imaging,

具有可以连续摄像的效果。 Having the effect of continuous imaging.
