[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), the timing shown in the conventional battery authentication method of battery authentication is performed in the first, and FIG. 4 (C), as shown in the timing of the prior Compared to the situation only battery residual quantity display remaining battery time than initially displayed using only battery authentication communication state ST4 slow time, but in the video camera 100, first, the remaining battery charge display, then certification treatment, compared with the situation only battery residual quantity display remaining battery time slower than the time initially displayed.

[0089] 即,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] That is, the present invention uses a video camera 100, initially only battery residual quantity display processing, after the battery authentication process appears on the LCD section 4 of the remaining battery time, so the remaining battery began You can use the additional time to time, even if the battery authentication process, but the user has not changed, valuable function displays the remaining battery power 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, the present invention uses a video camera 100, even if the battery authentication of users as a direct value of the 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I的破损等。 [0091] Further, in the video camera 100, the battery residual quantity display battery authentication is performed in parallel, it is impossible to use coarse battery is not genuine, may prevent the use of non-genuine battery apparatus body I is a result of breakage.

[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I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 display the remaining battery power and are using the side of the camera body I first microcomputer 3 and the battery pack 2 side second microcomputer 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 camera 100, in the same system, the remaining battery charge display processing and battery authentication processing, which is a system of communication can drive, you can reduce the cost of software development.

[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。 [0094] In addition, the camera 100, by dividing the battery authentication processing, display remaining battery power in the intermittent treatment progresses, thereby creating 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型计算机也可以进行电池认证,所以削减了成本。 [0095] Further, in the video camera 100, since battery authentication processing is carried out separately, even if high performance microcomputer is not used can also be battery authentication, thus cutting 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] Further, in the video camera 100, since battery authentication processing is divided, it is not high speed, even if the use of the microcomputer 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。 [0097] In addition, the camera 100, because saving the authentication processing results, so start the second time after the power is turned on, the remaining battery power can be devoted to the display processing, protecting 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或数码照相机这样的摄像装置中,可以缩短更换电池时的时间,减少错过摄像时机的可能,具有可以连续摄像的效果。 [0098] Furthermore, since battery authentication can be used immediately after the video camera 100, therefore, especially in such a video camera or digital camera 100 such imaging apparatus, it is possible to shorten the time for battery replacement, reduce the imaging timing may be missed, with possible continuous imaging effect.
