Description

本願発明は、カメラ付きドアホン子器の電源供給機能に関するものである。   The present invention relates to a power supply function of a camera-equipped doorphone slave unit.

従来から、特許第３２２９７９９号公報（特許文献１）に示されるように、テレビインターホンシステムは知られている。このテレビインターホンシステムは図９に示すように、カメラ付きドアホン子器２１に人体検知センサ２３を設けており、この人体検知センサ２３の人体検知時には、呼出ボタン２２を押圧する前にインターホン親機２からカメラ付きドアホン子器２１に給電され、ドアホン子器２１が動作する。これにより、呼出ボタン２２を押圧してからカメラ付きドアホン子器２１に給電し始める場合に比べれば、カメラ付きドアホン子器２１内部の映像回路部等が起動するまでに時間がかからないので来客の撮影及びインターホン親機２への画像転送も遅れず室内のインターホン親機２の傍の住戸人にとっては来客対応が即時に行える。

When the human body detection sensor 23 detects a human body, the interphone master unit 2 is pressed before the call button 22 is pressed. Is supplied to the door phone sub-unit with camera 21 and the door phone sub-unit 21 operates. As a result, it takes less time to activate the video circuit unit or the like inside the doorphone sub-unit with camera 21 than when the power is supplied to the doorphone sub-unit with camera 21 after the call button 22 is pressed. In addition, the image transfer to the intercom master unit 2 is not delayed, and a visitor can immediately respond to a dweller near the intercom master unit 2 in the room.
Japanese Patent No. 3229799

しかしながら、特許第３２２９７９９号公報に示される上記従来例のテレビインターホンシステムにあっては、人体検知センサ２３が人体を検知した場合、カメラ付きドアホン子器２１全体に対して給電を行っているので、例えば通行人体が通り過ぎた場合でも反応してしまい、待機時の消費電力が大きいという問題がある。   However, in the TV intercom system of the above-described conventional example disclosed in Japanese Patent No. 3229799, when the human body detection sensor 23 detects a human body, power is supplied to the entire door phone sub-unit 21 with a camera. For example, even when a passing human body passes, it reacts and there is a problem that power consumption during standby is large.

本願発明は上記背景技術に鑑みて発明されたものであり、その課題は、映像回路部等の起動の遅延を単純に回避するのみならず、待機時消費電力を出来るだけ低減することもできるカメラ付きドアホン子器を提供することにある。   The present invention has been invented in view of the above-mentioned background art, and its problem is not only to simply avoid a delay in starting the video circuit unit or the like, but also to reduce standby power consumption as much as possible. It is to provide a door phone with a door.

上記課題を解決するために、本願請求項１記載の発明では、撮像素子を用いて撮影する撮像回路部と、この撮像回路部が撮影した映像を処理する映像回路部と、この映像回路部が処理した映像を伝送する伝送回路部と、人体の存在を検知する人体検知センサと、インターホン親機を呼び出すための操作入力部と、撮像回路部と映像回路部と伝送回路部と人体検知センサとに給電する給電判断部と、を備えるカメラ付きドアホン子器において、給電判断部は、待機状態において人体検知センサに給電しており、人体検知センサが人体の接近を検知すれば撮像回路部と映像回路部とに給電を開始し、さらに操作入力部が操作されれば加えて伝送回路部にも給電を開始するものである。   In order to solve the above-described problem, in the invention according to claim 1 of the present application, an imaging circuit unit that captures an image using an imaging device, a video circuit unit that processes an image captured by the imaging circuit unit, and the video circuit unit include: A transmission circuit unit for transmitting processed video, a human body detection sensor for detecting the presence of a human body, an operation input unit for calling an interphone master unit, an imaging circuit unit, a video circuit unit, a transmission circuit unit, and a human body detection sensor, In the door phone with a camera, the power supply determination unit supplies power to the human body detection sensor in a standby state, and the image pickup circuit unit and the image are detected if the human body detection sensor detects the approach of the human body. Power supply to the circuit unit is started, and if the operation input unit is further operated, power is also supplied to the transmission circuit unit.

又、本願請求項２記載の発明では、上記請求項１記載のカメラ付きドアホン子器において、所定の検知エリアを有する第一の人体検知センサと、第一の人体検知センサよりも狭い検知エリアを有する第二の人体検知センサと、を備え、しかも、第二の人体検知センサの検知エリアが第一の人体検知センサの検知エリアに略含まれるように設定されており、給電判断部は、第一の人体検知センサが検知したときに撮像回路部への給電を開始し、第二の人体検知センサが検知したときに更に映像回路部への給電を開始するものであることを特徴としている。   Further, in the invention according to claim 2 of the present invention, in the door phone with the camera according to claim 1, the first human body detection sensor having a predetermined detection area and the detection area narrower than the first human body detection sensor are provided. And the second human body detection sensor is set so that the detection area of the second human body detection sensor is substantially included in the detection area of the first human body detection sensor. When one human body detection sensor detects, power supply to the imaging circuit unit is started, and when the second human body detection sensor detects, power supply to the video circuit unit is further started.

又、本願請求項３記載の発明では、上記請求項２記載のカメラ付きドアホン子器において、第一及び第二の人体検知センサがそれぞれ人体までの距離を検知できるものであり、しかも、人体までの距離を測るために電波を利用するものであることを特徴としている。   Further, in the invention according to claim 3 of the present application, in the door phone with a camera according to claim 2, the first and second human body detection sensors can detect the distance to the human body, respectively.

本願請求項１記載の発明のカメラ付きドアホン子器においては、人体を検知することで撮像回路部と映像回路部のみに給電を行い、伝送回路部の給電については操作入力部が押された後で行うため、撮像回路部及び映像回路部の起動の遅延を回避することができるとともに、待機時消費電力もできるだけ低減することができる。   In the door phone with a camera according to the first aspect of the present invention, power is supplied only to the imaging circuit unit and the video circuit unit by detecting a human body, and the operation input unit is pressed for power supply of the transmission circuit unit. Therefore, it is possible to avoid a delay in starting the imaging circuit unit and the video circuit unit, and to reduce standby power consumption as much as possible.

本願請求項２記載の発明のカメラ付きドアホン子器においては、検知エリアの広い人体検知センサが検知した場合に撮像回路部のみに給電し、検知エリアの狭い人体検知センサが検知した場合に映像回路部に給電を行うようにしているため、より待機時消費電力の低減が可能となる。   In the door phone with a camera according to the second aspect of the present invention, when the human body detection sensor with a wide detection area detects, the power is supplied only to the imaging circuit unit, and when the human body detection sensor with the narrow detection area detects, the video circuit Since power is supplied to the unit, standby power consumption can be further reduced.

本願請求項３記載の発明のカメラ付きドアホン子器においては、人体までの距離を測るために電波を利用しているので、人体を広い空間範囲で捉えることが可能となって人体検知センサの死角が狭まり、人体を検知する精度が向上する。   In the door phone with a camera according to the third aspect of the present invention, since the radio wave is used to measure the distance to the human body, the human body can be captured in a wide spatial range, and the dead angle of the human body detection sensor The accuracy of detecting the human body is improved.

以下、本願発明を添付図面に示す実施形態に基づいて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

図１、２は、本願請求項１に対応した第一の実施形態であるカメラ付きドアホン子器１を示している。   1 and 2 show a camera-equipped doorphone sub unit 1 according to a first embodiment corresponding to claim 1 of the present application.

このカメラ付きドアホン子器１は、インターホン親機２に接続され、撮像回路部３で撮影された映像をインターホン親機２に伝送するようになっており、図１に示すように、撮像素子を用いて撮影する撮像回路部３と、この撮像回路部３が撮影した映像を処理する映像回路部４と、この映像回路部４が処理した映像を伝送する伝送回路部５と、人体の存在を検知する人体検知センサ６と、インターホン親機２を呼び出すための操作入力部７と、撮像回路部３と映像回路部４と伝送回路部５と人体検知センサ６と操作入力部７とに給電する給電判断部８と、から構成される。ここで、操作入力部７をタッチパネル付き液晶画面としており、これ故に操作入力部７にも電源供給が要る。ただし、操作入力部７を電源供給不要なる旧来の操作ボタンとして構成すれば、操作入力部７には電源供給は不要となり、さらに低消費電力化を図れる。   The camera-equipped doorphone slave unit 1 is connected to an interphone master unit 2 and transmits an image captured by the imaging circuit unit 3 to the interphone master unit 2. As shown in FIG. The imaging circuit unit 3 that is used for imaging, the video circuit unit 4 that processes the video captured by the imaging circuit unit 3, the transmission circuit unit 5 that transmits the video processed by the video circuit unit 4, and the presence of the human body. Power is supplied to the human body detection sensor 6 to be detected, the operation input unit 7 for calling the interphone master unit 2, the imaging circuit unit 3, the video circuit unit 4, the transmission circuit unit 5, the human body detection sensor 6, and the operation input unit 7. And a power supply determination unit 8. Here, the operation input unit 7 is a liquid crystal screen with a touch panel. Therefore, the operation input unit 7 also needs to be supplied with power. However, if the operation input unit 7 is configured as a conventional operation button that does not require power supply, the operation input unit 7 does not need to be supplied with power and can further reduce power consumption.

給電判断部８は、給電用途の電源ドライバICとこれを制御するバイポーラトランジスタ回路などを具備するマイクロコンピュータユニットとを備えてなり、撮像回路部３と映像回路部４と伝送回路部５と人体検知センサ６と操作入力部７とについて選択的に給電する機能と、人体検知センサ６の人体検知結果と操作入力部７の操作入力有無検知結果とを検知する機能とを備える。   The power supply determination unit 8 includes a power supply driver IC for power supply and a microcomputer unit including a bipolar transistor circuit for controlling the power supply driver IC, and includes an imaging circuit unit 3, a video circuit unit 4, a transmission circuit unit 5, and a human body detection. A function of selectively supplying power to the sensor 6 and the operation input unit 7 and a function of detecting a human body detection result of the human body detection sensor 6 and an operation input presence / absence detection result of the operation input unit 7 are provided.

この給電判断部８は、カメラ付きドアホン子器１内部の動作に応じて必要な受電量をインターホン親機２から多段階的に給電されるものであり、このため、インターホン親機２からは、常時、最低でも、給電判断部８の動作に必要な電源電圧又は電源電流を供給され続けている。   The power supply determination unit 8 is a multi-stage power supply from the interphone base unit 2 according to the operation of the camera-equipped doorphone slave unit 1. For this reason, from the interphone base unit 2, The power supply voltage or power supply current necessary for the operation of the power supply determination unit 8 is always supplied at all times.

給電判断部８は、待機状態において人体検知センサ６と操作入力部７とに給電しており、人体検知センサ６が検知すれば撮像回路部３と映像回路部４とに給電を開始し、操作入力部７が押下されれば伝送回路部５に給電を開始する。   The power supply determination unit 8 supplies power to the human body detection sensor 6 and the operation input unit 7 in the standby state. When the human body detection sensor 6 detects the power supply, the power supply determination unit 8 starts power supply to the imaging circuit unit 3 and the video circuit unit 4. When the input unit 7 is pressed, power supply to the transmission circuit unit 5 is started.

この実施形態の動作について、図２に示すフローチャートに基づいて説明する。   The operation of this embodiment will be described based on the flowchart shown in FIG.

まず、給電判断部８は人体検知センサ６と操作入力部７とにあらかじめ給電しており、常に稼動させている。そして、人体検知センサ６が検知したのならば（Ｓ１）、給電判断部８が撮像回路部３と映像回路部４とに給電を開始する（Ｓ２）。そして、一定の時間、操作入力部７が押されるか否かをチェックする。操作入力部７が押されなければ、撮像回路部３と映像回路部４とに対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ３）。操作入力部７が押されたのならば、給電判断部８は伝送回路部５に給電し、伝送回路部５がインターホン親機２に対して画像伝送を開始する（Ｓ４）。   First, the power supply determination unit 8 supplies power to the human body detection sensor 6 and the operation input unit 7 in advance and always operates. Then, if the human body detection sensor 6 detects (S1), the power supply determination unit 8 starts to supply power to the imaging circuit unit 3 and the video circuit unit 4 (S2). Then, it is checked whether or not the operation input unit 7 is pressed for a certain time. If the operation input unit 7 is not pressed, power supply to the imaging circuit unit 3 and the video circuit unit 4 is stopped, and the process returns to the step (S1) (S3). If the operation input unit 7 is pressed, the power supply determination unit 8 supplies power to the transmission circuit unit 5, and the transmission circuit unit 5 starts image transmission to the interphone master unit 2 (S4).

したがって、人体を検知することで撮像回路部３と映像回路部４のみに給電を行い、伝送回路部５の給電については操作入力部７が押された後で行うため、撮像回路部３及び映像回路部４の起動の遅延を回避することができるとともに、待機時消費電力もできるだけ低減することができる。   Therefore, power is supplied only to the image pickup circuit unit 3 and the video circuit unit 4 by detecting the human body, and power supply to the transmission circuit unit 5 is performed after the operation input unit 7 is pressed. The delay in starting the circuit unit 4 can be avoided, and standby power consumption can be reduced as much as possible.

図３、４は、本願請求項１、２に対応した第二の実施形態であるカメラ付きドアホン子器１を示している。   FIGS. 3 and 4 show a camera-equipped doorphone child device 1 according to a second embodiment corresponding to claims 1 and 2 of the present application.

なお、ここでは、上記第一の実施形態と相違する事項についてのみ説明し、その他の事項については、上記第一の実施形態と同様であるのでその説明を省略する。   Here, only matters different from those in the first embodiment will be described, and other matters are the same as those in the first embodiment, and thus description thereof will be omitted.

このカメラ付きドアホン子器１は、図３に示すように、検知エリアの広い人体検知センサ６ａと、検知エリアの狭い人体検知センサ６ｂと、を設けている。   As shown in FIG. 3, the door phone subordinate 1 with a camera is provided with a human body detection sensor 6 a having a wide detection area and a human body detection sensor 6 b having a narrow detection area.

給電判断部８は、待機状態において感度の異なる２つの人体検知センサ６と、操作入力部７と、に給電しており、検知エリアの広い人体検知センサ６ａが検知すれば撮像回路部３への給電を開始し、検知エリアの狭い人体検知センサ６ｂが検知すれば映像回路部４への給電を開始し、操作入力部７が押下されたならば伝送回路部５に給電を開始する。   The power supply determination unit 8 supplies power to the two human body detection sensors 6 and the operation input unit 7 having different sensitivities in the standby state. If the human body detection sensor 6a having a wide detection area detects, the power supply determination unit 8 supplies the power to the imaging circuit unit 3. Power supply is started. If the human body detection sensor 6b having a narrow detection area detects, power supply to the video circuit unit 4 is started. If the operation input unit 7 is pressed, power supply to the transmission circuit unit 5 is started.

この実施形態の動作について、図４に示すフローチャートに基づいて説明する。   The operation of this embodiment will be described based on the flowchart shown in FIG.

まず、給電判断部８は人体検知センサ６ａと人体検知センサ６ｂと操作入力部７とにあらかじめ給電しており、常に稼動させている。人体検知センサ６ａが人体を検知したのならば（Ｓ１）、給電判断部８が撮像回路部３に給電を開始する（Ｓ２）。そして、一定の時間、人体検知センサ６ｂが人体を検知するか否かをチェックする。人体検知センサ６ｂが人体を検知しなければ、撮像回路部３に対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ３）。そして、人体検知センサ６ｂが検知したのならば、給電判断部８が映像回路部４に給電を開始する（Ｓ４）。そして、一定の時間、操作入力部７が押されるか否かをチェックする。操作入力部７が押されなければ、撮像回路部３と映像回路部４とに対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ５）。操作入力部７が押されたのならば、給電判断部８は伝送回路部５に給電し、伝送回路部５がインターホン親機２に対して画像伝送を開始する（Ｓ６）。   First, the power supply determination unit 8 supplies power to the human body detection sensor 6a, the human body detection sensor 6b, and the operation input unit 7 in advance, and always operates. If the human body detection sensor 6a detects a human body (S1), the power supply determination unit 8 starts to supply power to the imaging circuit unit 3 (S2). And it is checked whether the human body detection sensor 6b detects a human body for a fixed time. If the human body detection sensor 6b does not detect a human body, power supply to the imaging circuit unit 3 is stopped, and the process returns to the step (S1) (S3). And if the human body detection sensor 6b detects, the electric power feeding determination part 8 will start electric power feeding to the video circuit part 4 (S4). Then, it is checked whether or not the operation input unit 7 is pressed for a certain time. If the operation input unit 7 is not pressed, power supply to the imaging circuit unit 3 and the video circuit unit 4 is stopped, and the process returns to the step (S1) (S5). If the operation input unit 7 is pressed, the power supply determination unit 8 supplies power to the transmission circuit unit 5, and the transmission circuit unit 5 starts image transmission to the interphone master unit 2 (S6).

したがって、検知エリアの広い人体検知センサ６ａが検知した場合に撮像回路部３のみに給電し、検知エリアの狭い人体検知センサ６ｂが検知した場合に映像回路部４に給電を行うようにしているため、より待機時消費電力の低減が可能となる。   Therefore, power is supplied only to the imaging circuit unit 3 when the human body detection sensor 6a having a wide detection area is detected, and power is supplied to the video circuit unit 4 when the human body detection sensor 6b having a narrow detection area is detected. Thus, standby power consumption can be further reduced.

図５、６は、本願請求項１、３に対応した第三の実施形態であるカメラ付きドアホン子器１を示している。   5 and 6 show a camera-equipped doorphone child device 1 according to a third embodiment corresponding to claims 1 and 3 of the present application.

なお、ここでは、上記第一の実施形態と相違する事項についてのみ説明し、その他の事項については、上記第一の実施形態と同様であるのでその説明を省略する。   Here, only matters different from those in the first embodiment will be described, and other matters are the same as those in the first embodiment, and thus description thereof will be omitted.

このカメラ付きドアホン子器１は、図５に示すように、距離を検知することができる人体検知センサ６（距離センサ９）を設けている。この距離センサ９は、複数の所定の距離（図５では、Ｒ１とＲ２）をそれぞれ検知することができる。そして、人体までの距離を測るために電波を利用している。   As shown in FIG. 5, the door phone subordinate 1 with a camera is provided with a human body detection sensor 6 (distance sensor 9) that can detect a distance. The distance sensor 9 can detect a plurality of predetermined distances (R1 and R2 in FIG. 5). Radio waves are used to measure the distance to the human body.

この実施形態の動作について、図６に示すフローチャートに基づいて説明する。   The operation of this embodiment will be described based on the flowchart shown in FIG.

まず、給電判断部８は距離センサ９と操作入力部７とにあらかじめ給電しており、常に稼動させている。距離センサ９がＲ１の距離で人体を検知したのならば（Ｓ１）、給電判断部８が撮像回路部３に給電を開始する（Ｓ２）。そして、一定の時間、距離センサ９がＲ２の距離で人体を検知するか否かをチェックする。距離センサ９がＲ２の距離で人体を検知しなければ、撮像回路部３に対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ３）。そして距離センサ９がＲ２の距離で検知したのならば、給電判断部８が映像回路部４に給電を開始する（Ｓ４）。そして、一定の時間、操作入力部７が押されるか否かをチェックする操作入力部７が押されなければ、撮像回路部３と映像回路部４とに対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ５）。操作入力部７が押されたのならば、給電判断部８は伝送回路部５に給電し、伝送回路部５がインターホン親機２に対して画像伝送を開始する（Ｓ６）。   First, the power supply determination unit 8 supplies power to the distance sensor 9 and the operation input unit 7 in advance, and always operates. If the distance sensor 9 detects the human body at the distance R1 (S1), the power supply determination unit 8 starts to supply power to the imaging circuit unit 3 (S2). Then, it is checked whether or not the distance sensor 9 detects the human body at the distance R2 for a certain time. If the distance sensor 9 does not detect the human body at the distance R2, the power supply to the imaging circuit unit 3 is stopped, and the process returns to the step (S1) (S3). If the distance sensor 9 detects the distance R2, the power supply determination unit 8 starts to supply power to the video circuit unit 4 (S4). If the operation input unit 7 for checking whether or not the operation input unit 7 is pressed for a certain time is not pressed, the power supply to the imaging circuit unit 3 and the video circuit unit 4 is stopped, and the step of (S1) Return to (S5). If the operation input unit 7 is pressed, the power supply determination unit 8 supplies power to the transmission circuit unit 5, and the transmission circuit unit 5 starts image transmission to the interphone master unit 2 (S6).

なお、距離センサ９は、人体を広い空間範囲で捉えることが可能なセンサであればよく、 電波を利用する例えば電波センサや距離画像センサを用いれば実現可能である。   The distance sensor 9 may be any sensor that can capture a human body in a wide spatial range, and can be realized by using, for example, a radio wave sensor or a distance image sensor that uses radio waves.

したがって、距離センサ９がＲ１の距離で検知した場合に撮像回路部３のみに給電し、距離センサ９がＲ２の距離で検知した場合に映像回路部４に給電を行うようにしているため、より待機時消費電力の低減が可能となる。又、人体までの距離を測るために電波を利用しているので、人体を広い空間範囲で捉えることが可能となって人体検知センサの死角が狭まり、人体を検知する精度が向上する。   Therefore, when the distance sensor 9 detects at the distance R1, only the imaging circuit unit 3 is fed, and when the distance sensor 9 detects at the distance R2, the video circuit unit 4 is fed. It is possible to reduce standby power consumption. Further, since radio waves are used to measure the distance to the human body, the human body can be captured in a wide spatial range, the blind spot of the human body detection sensor is narrowed, and the accuracy of detecting the human body is improved.

図７、８は、本願請求項１に対応した第四の実施形態であるカメラ付きドアホン子器１を示している。   7 and 8 show a camera-equipped doorphone child device 1 according to a fourth embodiment corresponding to claim 1 of the present application.

なお、ここでは、上記第一の実施形態と相違する事項についてのみ説明し、その他の事項については、上記第一の実施形態と同様であるのでその説明を省略する。   Here, only matters different from those in the first embodiment will be described, and other matters are the same as those in the first embodiment, and thus description thereof will be omitted.

このカメラ付きドアホン子器１は、図7に示すように、LED照明１０と、LED照明１０が発した光の反射光を検知する光センサ１１と、から構成される人体検知センサ６を設けている。給電判断部８は、待機状態においてこのLED照明１０と、光センサ１１と、に給電をしている。   As shown in FIG. 7, the camera-equipped doorphone sub unit 1 includes a human body detection sensor 6 including an LED illumination 10 and an optical sensor 11 that detects reflected light of light emitted from the LED illumination 10. Yes. The power supply determination unit 8 supplies power to the LED illumination 10 and the optical sensor 11 in the standby state.

この実施形態の動作について、図８に示すフローチャートに基づいて説明する。   The operation of this embodiment will be described based on the flowchart shown in FIG.

まず、給電判断部８はLED照明１０と光センサ１１とにあらかじめ給電しており、常に稼動させている。そして、LED照明１０が発した光の反射光を光センサ１１が検知したのならば（Ｓ１）、給電判断部８が撮像回路部３と映像回路部４とに給電を開始する（Ｓ２）。そして、一定の時間、操作入力部７が押されるか否かをチェックする。操作入力部７が押されなければ、撮像回路部３と映像回路部４とに対する給電は停止し、（Ｓ１）のステップに戻る（Ｓ３）。操作入力部７が押されたのならば、給電判断部８は伝送回路部５に給電し、伝送回路部５がインターホン親機２に対して画像伝送を開始する（Ｓ４）。   First, the power supply determination unit 8 supplies power to the LED illumination 10 and the optical sensor 11 in advance, and always operates. If the optical sensor 11 detects the reflected light of the light emitted from the LED illumination 10 (S1), the power supply determination unit 8 starts to supply power to the imaging circuit unit 3 and the video circuit unit 4 (S2). Then, it is checked whether or not the operation input unit 7 is pressed for a certain time. If the operation input unit 7 is not pressed, power supply to the imaging circuit unit 3 and the video circuit unit 4 is stopped, and the process returns to the step (S1) (S3). If the operation input unit 7 is pressed, the power supply determination unit 8 supplies power to the transmission circuit unit 5, and the transmission circuit unit 5 starts image transmission to the interphone master unit 2 (S4).

したがって、人体を検知することで撮像回路部３と映像回路部４のみに給電を行い、伝送回路部５の給電については操作入力部７が押された後で行うため、撮像回路部３及び映像回路部４の起動の遅延を回避することができるとともに、待機時消費電力もできるだけ低減することができる。   Therefore, power is supplied only to the image pickup circuit unit 3 and the video circuit unit 4 by detecting the human body, and power supply to the transmission circuit unit 5 is performed after the operation input unit 7 is pressed. The delay in starting the circuit unit 4 can be avoided, and standby power consumption can be reduced as much as possible.
