【発明が解決しようとする課題】
しかしながら、以上のような従来の撮像装置では、内蔵する電池での作動を余儀なくされる非常時において、電池の残量が低下しても低下した電圧下で作動できるようには設定されていない。そのために、電池の残量が所定の水準以下になると機械的な動きを司る駆動部が十分に動作せず、又電池の残量によっては撮像装置の全体動作が停止するという課題を有していた。

自動的に元の状態に復帰するので、一々撮像位置や駆動モードを切り替える手間が省けるという作用を有する。
【0015】
以下、本発明の実施の形態について説明する。
【0016】
(実施の形態1)
本発明の一実施の形態は、撮像装置の電源である電池の残量が一定水準を割った場合でも何とか撮像機能を維持できるように、撮像部の機械的動作は緩慢になるものの、先ずは機械的動作を節電モードで行うようにして電池の消耗を抑え、更に電池の残量が低下した場合は撮像部の撮像位置を固定することで機械的動作を無くして電池の消耗を更に抑えて、最低限撮像機能の動作を図れるようにしたものである。
【0017】
以下、本発明の一実施の形態の詳細を図1〜図5を参照しながら説明する。
【0018】
図1は本発明の一実施の形態による撮像装置の構成を示すブロック図である。図2〜図5は本発明の一実施の形態による撮像装置の節電機能を示す模式図である。
【0019】
従来の技術の項目で述べたように、撮像装置は太陽電池や商用電源や風力発電機等の外部電源から供給される電力により作動すると共に、充電回路を通じて内蔵する電池に充電している。撮像装置に外部電源から電力が供給されなくなった場合、即ち太陽電池では日が沈んで使えなくなったり、商用電源では停電で使えなくなったり、風力発電では風が凪(なぎ)状態になったりした場合の非常時には、充電済みの電池から供給される電力が外部電源が復旧するまでの間の唯一の電源となる。そこで、本発明では外部電源が復旧するまでの間、如何にして電池の消耗を抑えて撮像装置の撮像機能を維持できるようにしたかを以下に説明する。
【0020】
電池の消耗を抑えて撮像機能を維持するには二通りの方法がある。一つは電池の残量が所定の第二の水準まで低下すると、換言すると撮像部を機械的に作動可能なもののあまり長くは持ち堪えられない水準まで低下すると、撮像部を節電モードで作動させ、撮像部の作動は緩慢になるものの撮像機能自体は十分なものを維持する方法である。もう一つは電池の残量が所定の第一の水準まで低下すると、換言すると撮像部を機械的に作動可能なもののあまり長くは持ち堪えられない第二の水準よりもさらに電池残量が少ない水準まで低下すると、撮像部の撮像位置を固定して撮像部の機械的作動を凍結することで電池の消耗を極力抑えて最低限の撮像機能を維持する方法である。
【0021】
先ず、電池の残量が所定の第二水準まで(例えば容量の五割まで)低下した場合に、電池の消耗を抑えて撮像機能を維持する方法を説明する。
【0022】
図1に示すように、大別すると撮像装置1は、撮影するための光学系や撮像素子等を有する撮像部2と、撮像部2の撮像位置を変化させるために撮像部2を駆動する駆動部3と、撮像装置1の電池動作時(外部電源から電源が供給されず、電池のみで動作する状態)の電源となる電池4と、撮像装置1の制御全般を担いCPUやRAMやROM等から成る制御部5とで構成されている。また、撮像装置1には画像やその他必要な情報をLAN等のネットワークに送信し、又ネットワークからの制御コマンドを受信可能とするために、ネットワークインターフェイス部6が備わっている。
【0023】
撮像装置1はネットワークに接続された外部ネットワーク端末(図示せず)からの遠隔操作により撮像部2や駆動部3を制御することができるように構成されている。例えば、外部ネットワーク端末から送信される撮像部2の撮像位置変更要求をネットワークインターフェイス部6を通じて受信すると、制御部5によりその要求を解析し、駆動部3を制御する。又同様に、外部ネットワーク端末から送信される撮像位置情報をネットワークインターフェイス部6を通じて受信すると、制御部5によりその要求を解析し、後述の撮像位置記憶部11に記憶する。
【0024】
この撮像装置1は通常は外部電源7から供給される電力により作動すると共に、充電回路8を通じて内蔵する電池4に充電している。外部電源7から電力が供給されなくなった非常時には、外部電源7が復旧するまでの間は充電済みの電池4から供給される電力で撮像装置1は作動することになる。なお、撮像装置1には太陽電池、風力発電機等を組み込むことも可能である。
【0025】
撮像部2はズームレンズ等の光学系やCCD等の撮像素子で構成されており、撮像部2のズームレンズをズーミングして画角を広角領域から望遠領域まで変化させたり、撮像部2の首を上下左右に振ることで撮像部2の撮像位置を変化させることができる。撮像部2のズーミングや首振りを行うための駆動部3はモータやギア等で構成されており、撮像部2の撮像位置を変化させるにはかなりの電力を消費することになるが、電源が電池4のみである場合には、撮像装置1を作動させるための電力を電池4が供給できる時間は限定されている。電池4の残量が低下していくと最初に機械的動作をする駆動部3の部分が作動不能になるばかりでなく、場合によっては撮像装置1全体の動作自体ができなくなる。
【0026】
そこで、電池4の残量を電池残量検知部9で検知しておき、電池4の残量が減少して所定の第二水準まで低下した際に、電池4の消耗を極力抑えるための節電対策を実施するように設定しておく。
【0027】
以下に、どのような方法に基づき撮像装置1の消費電力を低減させるかを、図1及び図2を参照しながら説明する。外部電源7が停止して電池4から撮像装置1へ電力の供給が始まると、徐々に電池4の残量が低下するのを電池残量検知部9が検知する。例えば、電池4の容量の五割を所定の第二水準とするならば、電池4の残量が五割まで低下したのを電池残量検知部9が検知すると、制御部5は駆動モード切り替え部10の駆動モードを切り替えて今までの通常モードから節電モードに移行し、駆動部3を節電モードで作動させる。モード切り替え部10の駆動モードが通常モードであれば、駆動部3は撮像部2の撮像位置を迅速に変化させるが、駆動モードが節電モードであれば駆動部3は撮像部2の撮像位置をゆっくりと変化させる。撮像部2のズーミングや首振りを迅速に行うにはかなりの電力を消費するが、ズーミングや首振りを経済速度(航空機や船舶でいう巡航速度)で行えば、動作は遅くなるものの迅速に行う場合に比べて消費電力は少なくて済む。このようにズーミングや首振りを経済速度で行うのが節電モードである。なお、所定の第二水準の設定は任意であるので電池4の容量の何割に設定しても良いが、なるべく電池4の容量に余裕がある内に節電モードに移行するのが好ましい。
【0028】
さて、図3に示すように、外部電源7が復旧すると充電回路8を通じて再び電池4への充電が行われる。所定の第二水準を下回っていた電池4の容量が減少から増加に転じ、所定の第二水準まで回復したのを電池4の残量を検知している電池残量検知部9が検知すると、制御部5は駆動モード切り替え部10の駆動モードを切り替えて今までの節電モードから通常モードに移行し、駆動部3を通常モードで作動させて撮像部2の撮像位置を迅速に変化させる。
【0029】
まとめると、電池4の残量を検知している電池残量検知部9が電池4の残量が減少方向にあり所定の第二水準まで低下したのを検知すると、制御部5はモード切り替え部10を通常モードから節電モードに切り替えて電池4の消耗を極力抑える。また、電池残量検知部9が電池4の残量が増加方向にあり所定の第二水準まで回復したのを検知すると、制御部5は駆動モード切り替え部10の駆動モードを節電モードから通常モードに切り替えて撮像部2の撮像位置を迅速に変化させるのである。
【0030】
なお、外部電源7が復旧した際には、前述したように電池4の残量を勘案して駆動モード切り替え部10の駆動モードを通常モードに切り替えても良いが、外部電源7が復旧した時点で撮像装置1には十分な電力が供給されると共に、電池4に対しても充電が行われるので、直ちに駆動モード切り替え部10の駆動モードを通常モードに切り替えるように設定しておいても良い。
【0031】
次に、電池の残量が所定の第一水準まで(例えば容量の二割まで)低下した場合に、電池の消耗を抑えて撮像機能を維持する方法を説明する。
【0032】
前述したように、電池動作時において、撮像装置1を作動させるための電力を電池4が供給できる時間は限定されている。撮像部2の撮像位置をズーミングや首振りで変化させるにはかなりの電力を消費するので、電池4の残量が低下していくと最初に機械的動作をする駆動部3の部分が作動不能になる場合があり、撮像部2の撮像位置を変化させられないようになる。
【0033】
そこで、電池4の残量を電池残量検知部9で検知しておき、電池4の残量が減少して前述した所定の第二水準まで低下した際に、電池4の消耗を極力抑えるための節電対策を実施し、電池4の容量の五割を所定の第二水準とするならば、電池4の残量が五割まで低下したのを電池残量検知部9が検知すると、制御部5は駆動モード切り替え部10の駆動モードを今までの通常モードから節電モードに切り替え、駆動部3を節電モードで作動させる。
【0034】
更に電池4の残量が減少して所定の第一水準まで低下した際に、電池4の消耗を極力抑えるための次の節電対策を実施するように設定しておく。
【0035】
以下に、どのような方法に基づき撮像装置1の撮像機能を確保するかを、図1及び図4を参照しながら説明する。外部電源7が停止して電池4から撮像装置1へ電力の供給が始まると、徐々に電池4の残量が低下するのを電池残量検知部9が検知する。例えば、電池4の容量の二割を所定の第一水準とするならば、電池4の残量が二割まで低下したのを電池残量検知部9が検知すると、制御部5は撮像位置記憶部11に記憶済みの所定の撮像位置を読み出し、現在の節電モードで駆動部3を作動させて経済速度で撮像部2のズーミングや首振りを行い、撮像部2の撮像位置を所定の撮像位置まで変化させて撮像部2をこの撮像位置で固定する。
【0036】
撮像位置記憶部11に記憶させておく所定の撮像位置とは次のようなものである。例えば、撮像部2のズームレンズの画角は最大広角(例えば画角74度ならば35mmフィルム換算で28mmの広角に相当)に設定し、撮像部2の首振りは中央(上下左右に0度の位置)に設定する。例えば、撮像部2のズームレンズの画角は最大望遠(例えば画角18度30分ならば35mmフィルム換算で135mmの望遠に相当)に設定し、撮像部2の首振りは下に10度、右に10度に設定する等々である。所定の撮像位置は撮像装置1の設置場所により最適な状態を任意に設定できるようになっている。
【0037】
なお、この設定は、ネットワークに接続された外部ネットワーク端末から送信される撮像部2の固定位置情報を、ネットワークインターフェイス部6を介して受信し、制御部5により撮像位置記憶部11にその固定位置情報を設定することにより行われる。
【0038】
撮像部2の撮像位置を所定の撮像位置で固定し、これ以降は撮像装置1は駆動部3の動作を禁止して機械的動作を全く行わない節電状態に移行する。従って、電力の消費の多い駆動部3による電力消費を避けることができることになる。因に、この駆動部3の動作の禁止には、ネットワークインターフェイス部6を介して受信した駆動部3の動作要求を拒否することも含まれる。つまり、電池4の電力の残量が乏しい状態での撮像部2の外部からの遠隔操作を許していると、電池4の電力が更に低下して撮像部2が動作途中で停止することも有り得るので、予防措置としてネットワークインターフェイス部6を介して受信した駆動部3の動作要求を拒否するということである。なお、所定の第一水準の設定は任意であるので電池4の容量の何割に設定しても良いが、なるべく電池4の容量に余裕がある内に節電状態に移行するのが好ましい。
【0039】
さて、図5に示すように、外部電源7が復旧すると充電回路8を通じて再び電池4への充電が行われる。所定の第一水準を下回っていた電池4の容量が減少から増加に転じ、所定の第一水準まで回復したのを電池4の残量を検知している電池残量検知部9が検知すると、制御部5は駆動部3の動作の禁止を解き駆動モード切り替え部10の駆動モードを節電モードに復帰させる。更に電池4への充電が行われ、所定の第二水準を下回っていた電池4の容量が所定の第二水準まで回復したのを電池4の残量を検知している電池残量検知部9が検知すると、制御部5は駆動モード切り替え部10の駆動モードを今までの節電モードから通常モードに切り替え、駆動部3を通常モードで作動させて撮像部2の撮像位置を迅速に変化させる。
【0040】
まとめると、電池4の残量を検知している電池残量検知部9が電池4の残量が減少方向にあり所定の第一水準まで低下したのを検知すると、制御部5は現在の節電モードで駆動部3を作動させて撮像部2の撮像位置を所定の撮像位置まで変化させる。そして、制御部5は駆動部3の動作を禁止することにより、撮像部2をこの撮像位置で固定して電池4の消耗を極力抑える。また、電池残量検知部9が電池4の残量が増加方向にあり所定の第一水準まで回復したのを検知すると、制御部5は駆動部3の動作の禁止を解き、駆動モード切り替え部10の駆動モードを節電モードに復帰させて撮像部2の撮像位置を経済速度で変化させる。更に電池4への充電が行われて電池4の残量が所定の第二水準まで回復したのを電池残量検知部9が検知すると、制御部5は駆動モード切り替え部10の駆動モードを節電モードから通常モードに切り替えて撮像部2の撮像位置を迅速に変化させるのである。
【0041】
なお、外部電源7が復旧した際には、前述したように電池4の残量を勘案して駆動部3の動作の禁止を解き、駆動モード切り替え部10の駆動モードを節電モードに復帰させても良いが、外部電源7が復旧した時点(外部電源7の接続を検出した時点)で撮像装置1には十分な電力が供給されると共に、電池4に対しても充電が行われるので、直ちに駆動部3の動作の禁止を解き、駆動モード切り替え部10の駆動モードを一挙に通常モードに復帰させるように設定しておいても良い。
【0042】
前述したように、撮像装置1にはネットワークインターフェイス部6が備わっているので、撮像装置1をLAN等のネットワークに接続して撮像装置1の電池残量検知部9が検知した電池4の残量や、現在の駆動モードが通常モードなのか節電モードなのかを外部モニタに表示するようにしても良い。また、表示された電池4の残量や現在の駆動モードを確認した外部モニタの監視者が、必要に応じて遠隔操作で駆動モード切り替え部10の駆動モードを切り替えるようにしても良い。更に、外部モニタの監視者が遠隔操作で撮像位置を変化させ、撮像位置からの画像を確認しながら撮像部2を最適な撮像位置で固定したり、あるいは撮像位置の解除をするようにしても良い。
【0043】
以上に述べたように、本発明では撮像装置の電源である電池の残量が低下した場合には、先ず撮像部の機械的動作は節電モードで作動させ、更に電池の残量が低下すると今度は撮像部の撮像位置を固定して機械的動作を禁止し、節電対策を講じることで電池の消耗を極力抑えるようにしたので、撮像機能を長時間に亘り維持することが可能となる。
【0044】
【発明の効果】
以上のように本発明の撮像装置によれば、撮像装置を作動させるための電池と、電池の残量を検知するための電池残量検知部と、撮影するための光学系等を有する撮像部と、撮像部の撮像位置を変化させるための駆動部と、所定の撮像位置を記憶するための撮像位置記憶部と、を備えた撮像装置であって、
電池の残量が所定の第一の水準まで低下したのを電池残量検知部が検知すると、撮像部を撮像位置記憶部に記憶した所定の撮像位置へ移動後、駆動部の動作を制限する構成としたものである。
【0045】
このことにより、電力の消費の多い駆動部の動作を制限することができるため、撮像装置の機械的動作は制限されるものの電池の消耗は最小限度まで抑えられるので、長時間に亘り最低限度の撮像機能を維持できるという効果がある。

[0015]
Hereinafter, embodiments of the present invention will be described.
[0016]
(Embodiment 1)
In one embodiment of the present invention, the mechanical operation of the imaging unit is slowed down so that the imaging function can be maintained even if the remaining amount of the battery serving as the power supply of the imaging device falls below a certain level. The mechanical operation is performed in the power saving mode to suppress the consumption of the battery, and further, when the remaining amount of the battery is reduced, the imaging position of the imaging unit is fixed to eliminate the mechanical operation and further reduce the consumption of the battery. , So that the operation of the imaging function can be at least performed.
[0017]
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
[0018]
FIG. 1 is a block diagram illustrating a configuration of an imaging device according to an embodiment of the present invention. 2 to 5 are schematic diagrams illustrating a power saving function of the imaging device according to the embodiment of the present invention.
[0019]
As described in the section of the related art, the imaging apparatus operates by power supplied from an external power supply such as a solar cell, a commercial power supply, or a wind power generator, and charges an internal battery through a charging circuit. When power is no longer supplied from an external power supply to the imaging device, that is, when the sun sets in the solar cell and becomes unusable, when the commercial power supply becomes unavailable due to a power outage, or when wind power is generated, the wind becomes calm. In an emergency, the power supplied from the charged battery is the only power supply until the external power supply is restored. Therefore, in the present invention, a description will be given below of how the consumption of the battery is suppressed and the imaging function of the imaging apparatus can be maintained until the external power supply is restored.
[0020]
There are two methods for maintaining the imaging function while suppressing battery consumption. One is that when the remaining battery level drops to a predetermined second level, in other words, when the imaging unit drops to a level that can be mechanically operated but cannot be sustained for a long time, the imaging unit is operated in a power saving mode, In this method, the operation of the imaging unit is slow, but the imaging function itself is sufficient. Second, when the remaining battery level drops to a predetermined first level, in other words, the level at which the remaining battery level is lower than the second level, which can mechanically operate the imaging unit but cannot withstand for a long time. When the temperature decreases to a lower level, a method of fixing the imaging position of the imaging unit and freezing the mechanical operation of the imaging unit to minimize battery consumption and maintain the minimum imaging function.
[0021]
First, a description will be given of a method of maintaining the imaging function while suppressing battery consumption when the remaining battery level drops to a predetermined second level (for example, to 50% of the capacity).
[0022]
As shown in FIG. 1, when roughly classified, an imaging apparatus 1 includes an imaging unit 2 having an optical system and an imaging element for capturing an image, and a driving unit that drives the imaging unit 2 to change an imaging position of the imaging unit 2. Unit 3, a battery 4 serving as a power supply when the imaging apparatus 1 operates on a battery (power is not supplied from an external power supply, and operates only with a battery), and a CPU, a RAM, a ROM, and the like that perform overall control of the imaging apparatus 1 And a control unit 5 composed of In addition, the imaging apparatus 1 is provided with a network interface unit 6 for transmitting images and other necessary information to a network such as a LAN, and enabling control commands from the network to be received.
[0023]
The imaging device 1 is configured to be able to control the imaging unit 2 and the driving unit 3 by remote control from an external network terminal (not shown) connected to a network. For example, when a request to change the imaging position of the imaging unit 2 transmitted from an external network terminal is received through the network interface unit 6, the control unit 5 analyzes the request and controls the driving unit 3. Similarly, when the imaging position information transmitted from the external network terminal is received through the network interface unit 6, the request is analyzed by the control unit 5 and stored in the imaging position storage unit 11 described later.
[0024]
The imaging device 1 normally operates with power supplied from an external power supply 7 and charges a built-in battery 4 through a charging circuit 8. In an emergency when power is no longer supplied from the external power supply 7, the imaging apparatus 1 operates with the power supplied from the charged battery 4 until the external power supply 7 is restored. In addition, it is also possible to incorporate a solar cell, a wind power generator, and the like into the imaging device 1.
[0025]
The imaging unit 2 includes an optical system such as a zoom lens and an imaging device such as a CCD. The zoom lens of the imaging unit 2 is zoomed to change the angle of view from a wide-angle region to a telephoto region, The image pickup position of the image pickup section 2 can be changed by shaking the mouse up, down, left, and right. The driving unit 3 for performing zooming and swinging of the imaging unit 2 is configured by a motor, gears, and the like. To change the imaging position of the imaging unit 2, considerable power is consumed. When only the battery 4 is used, the time during which the battery 4 can supply power for operating the imaging device 1 is limited. When the remaining amount of the battery 4 decreases, not only the part of the driving unit 3 that performs a mechanical operation first becomes inoperable, but also in some cases, the entire operation of the imaging apparatus 1 cannot be performed.
[0026]
Therefore, the remaining amount of the battery 4 is detected by the battery remaining amount detection unit 9 and when the remaining amount of the battery 4 decreases to a predetermined second level, power saving for minimizing consumption of the battery 4 is performed. Set to take measures.
[0027]
Hereinafter, a method for reducing the power consumption of the imaging device 1 based on the method will be described with reference to FIGS. 1 and 2. When the external power supply 7 is stopped and the supply of power from the battery 4 to the imaging device 1 is started, the battery remaining amount detecting unit 9 detects that the remaining amount of the battery 4 gradually decreases. For example, if 50% of the capacity of the battery 4 is set to the predetermined second level, when the battery remaining amount detecting unit 9 detects that the remaining amount of the battery 4 has decreased to 50%, the control unit 5 switches the driving mode. The drive mode of the unit 10 is switched to shift from the normal mode to the power saving mode, and the driving unit 3 is operated in the power saving mode. When the driving mode of the mode switching unit 10 is the normal mode, the driving unit 3 quickly changes the imaging position of the imaging unit 2, but when the driving mode is the power saving mode, the driving unit 3 changes the imaging position of the imaging unit 2. Change slowly. To quickly zoom and swing the imaging unit 2 consumes a considerable amount of power. Power consumption is smaller than in the case. The power saving mode performs zooming and swinging at an economic speed in this manner. The setting of the predetermined second level is arbitrary and may be set to any percentage of the capacity of the battery 4, but it is preferable to shift to the power saving mode while the capacity of the battery 4 has a margin as much as possible.
[0028]
Now, as shown in FIG. 3, when the external power supply 7 is restored, the battery 4 is charged again through the charging circuit 8. When the battery remaining amount detecting unit 9 that detects the remaining amount of the battery 4 detects that the capacity of the battery 4 that has been lower than the predetermined second level has turned from a decrease to an increase and has recovered to the predetermined second level, The control unit 5 switches the drive mode of the drive mode switching unit 10 to shift from the current power saving mode to the normal mode, and operates the drive unit 3 in the normal mode to quickly change the imaging position of the imaging unit 2.
[0029]
In summary, when the battery remaining amount detecting unit 9 that detects the remaining amount of the battery 4 detects that the remaining amount of the battery 4 is decreasing and has decreased to a predetermined second level, the control unit 5 sets the mode switching unit. 10 is switched from the normal mode to the power saving mode to minimize the consumption of the battery 4. When the remaining battery level detecting unit 9 detects that the remaining level of the battery 4 is increasing and has recovered to the predetermined second level, the control unit 5 changes the driving mode of the driving mode switching unit 10 from the power saving mode to the normal mode. To quickly change the imaging position of the imaging unit 2.
[0030]
When the external power supply 7 is restored, the drive mode of the drive mode switching unit 10 may be switched to the normal mode in consideration of the remaining amount of the battery 4 as described above. Thus, since sufficient power is supplied to the imaging apparatus 1 and the battery 4 is also charged, the drive mode of the drive mode switching unit 10 may be set to immediately switch to the normal mode. .
[0031]
Next, a description will be given of a method of maintaining the imaging function while suppressing battery consumption when the remaining battery level decreases to a predetermined first level (for example, to 20% of the capacity).
[0032]
As described above, the time during which the battery 4 can supply power for operating the imaging device 1 during battery operation is limited. Changing the imaging position of the imaging unit 2 by zooming or swinging consumes considerable power. Therefore, when the remaining amount of the battery 4 decreases, the part of the driving unit 3 which performs mechanical operation first becomes inoperable. And the imaging position of the imaging unit 2 cannot be changed.
[0033]
Therefore, the remaining amount of the battery 4 is detected by the battery remaining amount detecting unit 9 and, when the remaining amount of the battery 4 decreases to the above-described predetermined second level, the consumption of the battery 4 is minimized. If 50% of the capacity of the battery 4 is set to the predetermined second level and the battery remaining amount detecting unit 9 detects that the remaining amount of the battery 4 has decreased to 50%, the control unit 5 switches the drive mode of the drive mode switching unit 10 from the usual mode to the power saving mode, and operates the driving unit 3 in the power saving mode.
[0034]
Further, when the remaining amount of the battery 4 decreases to a predetermined first level, the following power saving measures for minimizing the consumption of the battery 4 are set.
[0035]
Hereinafter, a method for ensuring the imaging function of the imaging apparatus 1 will be described with reference to FIGS. 1 and 4. When the external power supply 7 is stopped and the supply of power from the battery 4 to the imaging device 1 is started, the battery remaining amount detecting unit 9 detects that the remaining amount of the battery 4 gradually decreases. For example, if 20% of the capacity of the battery 4 is set to the predetermined first level, when the battery remaining amount detecting unit 9 detects that the remaining amount of the battery 4 has decreased to 20%, the control unit 5 stores the imaging position. A predetermined imaging position stored in the unit 11 is read out, the driving unit 3 is operated in the current power saving mode, zooming and swinging of the imaging unit 2 are performed at an economic speed, and the imaging position of the imaging unit 2 is changed to the predetermined imaging position. And the image pickup unit 2 is fixed at this image pickup position.
[0036]
The predetermined imaging positions stored in the imaging position storage unit 11 are as follows. For example, the angle of view of the zoom lens of the image pickup unit 2 is set to the maximum wide angle (for example, if the angle of view is 74 degrees, it is equivalent to a wide angle of 28 mm in 35 mm film conversion), and the swing of the image pickup unit 2 is centered (0 degrees vertically, horizontally, and Position). For example, the angle of view of the zoom lens of the imaging unit 2 is set to the maximum telephoto (for example, if the angle of view is 18 degrees 30 minutes, it is equivalent to 135 mm telephoto in terms of 35 mm film), and the imaging unit 2 swings 10 degrees downward. Set it to 10 degrees to the right, and so on. The predetermined imaging position can be arbitrarily set to an optimal state depending on the installation location of the imaging device 1.
[0037]
This setting is performed by receiving the fixed position information of the imaging unit 2 transmitted from the external network terminal connected to the network via the network interface unit 6, and storing the fixed position information in the imaging position storage unit 11 by the control unit 5. This is done by setting information.
[0038]
The imaging position of the imaging unit 2 is fixed at a predetermined imaging position, and thereafter, the imaging device 1 prohibits the operation of the driving unit 3 and shifts to a power saving state in which no mechanical operation is performed. Therefore, it is possible to avoid power consumption by the driving unit 3 which consumes a large amount of power. Prohibiting the operation of the driving unit 3 includes rejecting the operation request of the driving unit 3 received via the network interface unit 6. In other words, if remote operation from outside of the imaging unit 2 is allowed while the remaining power of the battery 4 is low, the power of the battery 4 may be further reduced and the imaging unit 2 may be stopped during operation. Therefore, as a precautionary measure, the operation request of the drive unit 3 received via the network interface unit 6 is rejected. Note that the predetermined first level can be set arbitrarily, so that it may be set to any percentage of the capacity of the battery 4. However, it is preferable to shift to the power saving state while the capacity of the battery 4 has a margin as much as possible.
[0039]
Now, as shown in FIG. 5, when the external power source 7 is restored, the battery 4 is charged again through the charging circuit 8. When the battery remaining amount detecting unit 9 that detects the remaining amount of the battery 4 detects that the capacity of the battery 4 that has been lower than the predetermined first level has turned from a decrease to an increase and has recovered to the predetermined first level, The control unit 5 releases the prohibition of the operation of the driving unit 3 and returns the driving mode of the driving mode switching unit 10 to the power saving mode. Further, when the battery 4 is charged and the capacity of the battery 4 that has fallen below the predetermined second level has recovered to the predetermined second level, the remaining battery level detection unit 9 detects the remaining level of the battery 4. Is detected, the control unit 5 switches the drive mode of the drive mode switching unit 10 from the current power saving mode to the normal mode, operates the drive unit 3 in the normal mode, and quickly changes the imaging position of the imaging unit 2.
[0040]
In summary, when the battery remaining amount detecting unit 9 that detects the remaining amount of the battery 4 detects that the remaining amount of the battery 4 is decreasing and has decreased to a predetermined first level, the control unit 5 sets the current power saving. The drive unit 3 is operated in the mode to change the imaging position of the imaging unit 2 to a predetermined imaging position. Then, the control unit 5 inhibits the operation of the driving unit 3, thereby fixing the imaging unit 2 at this imaging position and minimizing the consumption of the battery 4. When the remaining battery level detecting unit 9 detects that the remaining level of the battery 4 is increasing and has recovered to the predetermined first level, the control unit 5 releases the prohibition of the operation of the driving unit 3 and the driving mode switching unit. The driving mode of the imaging unit 2 is returned to the power saving mode to change the imaging position of the imaging unit 2 at an economical speed. Further, when the battery 4 is charged and the remaining battery level detecting unit 9 detects that the remaining level of the battery 4 has recovered to the predetermined second level, the control unit 5 switches the driving mode of the driving mode switching unit 10 to the power saving mode. The mode is switched to the normal mode, and the imaging position of the imaging unit 2 is quickly changed.
[0041]
When the external power supply 7 is restored, the prohibition of the operation of the drive unit 3 is released in consideration of the remaining amount of the battery 4 as described above, and the drive mode of the drive mode switching unit 10 is returned to the power saving mode. However, when the external power supply 7 is restored (when the connection of the external power supply 7 is detected), sufficient power is supplied to the imaging device 1 and the battery 4 is charged, so that the battery 4 is charged. The prohibition of the operation of the drive unit 3 may be lifted, and the drive mode of the drive mode switching unit 10 may be set to return to the normal mode at once.
[0042]
As described above, since the imaging device 1 is provided with the network interface unit 6, the imaging device 1 is connected to a network such as a LAN, and the remaining amount of the battery 4 detected by the battery remaining amount detection unit 9 of the imaging device 1. Alternatively, whether the current drive mode is the normal mode or the power saving mode may be displayed on an external monitor. In addition, the monitor of the external monitor that has confirmed the displayed remaining amount of the battery 4 and the current drive mode may switch the drive mode of the drive mode switching unit 10 by remote control as needed. Further, the monitor of the external monitor may change the imaging position by remote control, and fix the imaging unit 2 at the optimal imaging position or release the imaging position while checking the image from the imaging position. good.
[0043]
As described above, according to the present invention, when the remaining amount of the battery, which is the power supply of the imaging device, decreases, first, the mechanical operation of the imaging unit is operated in the power saving mode. Since the mechanical position is prohibited by fixing the imaging position of the imaging unit and taking measures to conserve power, the consumption of the battery is minimized, so that the imaging function can be maintained for a long time.
[0044]
【The invention's effect】
As described above, according to the imaging device of the present invention, a battery for operating the imaging device, a battery remaining amount detection unit for detecting the remaining amount of the battery, and an imaging unit including an optical system for photographing and the like An imaging apparatus comprising: a driving unit for changing an imaging position of an imaging unit; and an imaging position storage unit for storing a predetermined imaging position.
When the battery remaining amount detecting unit detects that the remaining amount of the battery has decreased to the predetermined first level, the operation of the driving unit is restricted after moving the imaging unit to the predetermined imaging position stored in the imaging position storage unit. It is configured.
[0045]
As a result, the operation of the driving unit that consumes a large amount of power can be restricted, and the mechanical operation of the imaging device is restricted, but the consumption of the battery is suppressed to the minimum, so that the minimum There is an effect that the imaging function can be maintained.
