利用灯号信号启动的车侧影像辅助系统 技术领域
本发明有关一种车侧影像辅助系统， 尤指一种利用灯号信号当作启动信 号源以选择并启动至少二个车侧摄影机装置中至少一对应的摄影机装置， 并 在一影像信号源切换处理器中增设一灯号信号判读处理器用以当一灯号信号 启动并输入后， 可在一预设的临界时间点之后才开始判读并持续进行判读一 段预设时间之后才输出判读结果， 以达成安装容易并适用各种车体安装且判 读准确度高的使用功效。 背景技术
车侧影像辅助系统已渐渐成为车辆的安全配备， 一般的车侧影像辅助系 统在一车辆的车侧， 如车后侧、 车左侧及车右侧等不同位置， 设置多个摄影 机装置（camera ) , 当驾者在倒车或左、 右转向时， 可同步启动其中一对应的 摄影机装置， 如倒车时即启动该车后侧摄影机装置， 左或右转向时即分别启 动该车左侧或车右侧摄影机装置， 以分别撷取该对应的车侧的影像， 并将该 对应的摄影机装置所撷取该对应车侧的影像输出至并显示于一显示器装置的 荧幕上， 而形成至少一影像画面， 即包含一个或多个画面； 以目前台湾市场 上既有的一种车款， 如 Luxgen汽车， 为例说明， 该车的车侧影像辅助系统在 倒车时， 可在一荧幕上同时显示前、 后、 左、 右， 如同于 360度范围， 之车 侧影像， 而在左或右转向时， 又可在该荧幕上分别显示车左侧或车右侧的影 像， 以增进倒车、 停车及左或右转向时的安全性。
然而， 与本案相关的现有技术， 如中国台湾省新型专利 TW M371134U1 , 通常利用车体信号， 如档位信号或方向灯开关信号， 当作启动信号源， 即藉 一种灯号的启动模式， 用以当作启动信号源以分别启动该车侧的对应摄影机 装置并在荧幕上形成画面供驾者观看； 但此种启动模式的车侧影像辅助系统， 安装时须与档位如倒车档或方向灯开关直接连结， 因此就目前的车体设计而 言， 一般是在车辆出厂时即已随车安装， 也就是已内建在车体； 而若要在出 厂后再自行安装， 则相当不容易， 常须交由该车体的专门或特约修护厂进行 安装， 一般非特约的修护厂并无法简易施工安装， 不利于车侧影像辅助系统 的行销及普及化， 也相对增加车主或爱用者的困扰， .例如自行安装时， 因施 工安装不易， 故安装成本相对增加， 且可能会破坏原来车体或内部装备的完 整性。
又若考虑改为利用灯号信号， 如倒车灯号、 左或右向灯亏， 当作后动信 号源， 即通过倒车灯号、 左或右向灯号的启动 （灯亮） ， 在此可视为一种灯 号的结果模式（即不同于前述的灯号的启动模式） ， 用以当作启动信号源以 分别启动该车侧的对应摄影机装置， 藉以取代先前技术利用车体信号当作启 动信号源。 但此种结果模式的车侧影像辅助系统， 在实际使用时仍会遇到下 列问题：
首先， 一般车辆的灯号信号包含倒车灯号、 左或右向灯号及警示灯号， 其中该警示灯号是左、 右向灯号同时启动而视为同步灯号， 但以左、 右向灯 号二分开电路的连结型态而言， 该警示灯号虽视为左右向灯号同时启动， 但 严格而言却非为完全同步的灯号， 也就是当驾者切换成警示灯号时， 该左、 右向灯号之间仍存在一时间差， 该时间差常随各种车款或车体的不同设计而 不同， 一般约在 0.15秒至 0.25秒之间或更小； 因此若未考虑该时间差， 则当 驾者切换成警示灯号时， 该左、 右向灯号中之一可能先启动， 如左向灯号先 亮灯而右向灯号慢亮灯（二者之间的时间差约 0.15秒至 0.25秒或更小） ， 此 时影像信号源切换处理器可能先以该左向灯号当作启动信号源以对应启动该 车左侧摄影机装置以撷取车左侧的影像并于荧幕上显示车左侧画面， 再而因 右向灯号也接着亮灯， 此时影像信号源切换处理器马上又以该右向灯号当作 启动信号源以对应启动该车右侧摄影机装置以撷取车右侧的影像并于荧幕上 显示车右侧画面， 造成荧幕上车左侧画面及车右侧画面快速切换而无法观看， 或如左向灯号先亮灯而右向灯号慢亮灯（时间差约 0.15- 0.25秒或更小） ， 此 时影像信号源切换处理器可能先以该左向灯号当作启动信号源以对应启动该 车左侧摄影机装置以撷取车左侧的影像并输出且显示于荧幕上而形成车左侧 画面， 再而因右向灯号也亮灯， 但此时影像信号源切换处理器仍停留在左向 灯号当作启动信号源以对应启动该车左侧摄影机装置以撷取车左侧的影像并 输出且显示于荧幕上而形成车左侧画面， 造成荧幕上车左侧画面持续停留， 也就是影像信号源切换处理器无法准确地以警示灯号当作启动信号源以对应 启动原设定的对应摄影机装置， 如： 假设当警示灯号启动时， 原设定为同时 启动多个摄影机装置， 如包含车左、 右侧及车后侧等至少三个摄影机装置以 撷取车侧三车侧方向的影像并输出且显示于荧幕上而形成三个次画面， 即在 荧幕上同时显示车左、 右侧及车后侧的影像画面， 但依据原有的影像信号源 切换处理器却无法达到原设定的效果； 因此对应启动的准确度受到影响， 相 对降低车侧影像辅助系统的使用效率。 至于在一荧幕上显示单一个主画面或 多个次画面， 乃利用目前荧幕画面显示方式的习知技术可以达成， 故在此不 另再赘述。
再而， 一般车辆的灯号信号， 包含倒车灯号、 左或右向灯号及警示灯号， 无论是否启动 （亮灯）或关闭 （熄灭） ， 其相关的连接电路上仍难免有其他 的杂讯产生， 如在车上利用该车的电池电源而同时使用其他的电气设备时即 有杂讯产生； 虽然该杂讯的产生时间会比一般灯号信号短， 如一般杂讯的产 生时间只有几毫秒而已， 一般不超过 8毫秒（0.008秒） ， 但当该杂讯与灯号 信号混杂在一起时， 该车侧影像辅助系统仍容易因该其他杂讯的产生而发生 误判的情形， 相对使对应启动的准确度受到影响。
另外， 以目前有关车侧影像辅助系统的现有技术而论, 包含中国台湾省 新型专利 TW M371134U1及其他利用车体信号当作启动信号源以启动对应的 车侧摄影机装置的车侧影像辅助系统， 该等先前技术基本上并未考虑到影像 信号输出并显示于荧幕上的优先权问题； 在此所谓的优先权， 是以启动灯号 的动作重要性来决定采用那一对应的车侧摄影机装置并在该显示器装置的荧 幕上优先显示该对应车侧的影像画面， 因而具有取代性和不被取代性的优先 权处理功能； 以一般驾者开车习惯而言， 开车时应配合正确启动灯号的操作 习惯， 而每一单独启动灯号的动作基本上皆应有一定主张该动作的用意， 并 应有事件 （动作） 的轻重緩急的区别， 即该事件 （动作）具有可被取代或不 可被取代的区别， 例如： 一般而言， 警示灯动作（如车子故障或要路边停车） 的重要性大于转向灯动作， 因此警示灯动作可立即取代转向灯动作， 即警示 灯动作所对应显示的影像画面应立即取代转向灯动作所对应显示的影像画 面， 但若上述动作反向操作时， 则为不可被取代性动作； 又如转向灯动作的 重要性大于倒车 （倒档）动作， 因此转向灯动作可立即取代倒车 （倒档） 动 作， 即转向灯动作所对应显示的影像画面应立即取代倒车 （倒档） 动作所对 应显示的影像画面， 但若上述动作为反向操作时， 则为不可被取代性动作； 又如左向灯和右向灯为同等重要动作， 因此左向灯和右向灯警应可立即相互 取代， 即新一转向灯动作所对应显示的影像画面应立即取代前一转向灯动作 所对应显示的影像画面。 因此， 车侧影像辅助系统在荧幕上所对应显示的车 画面， 即预先设定一优先权处理逻辑， 则不但可进一步符合一般驾者的开车 习惯， 且能提升车侧影像辅助统的使用效率； 然而， 目前使用的车侧影像辅 助系统却完全未考虑到上述的优先权问题， 该等先前技术在使用时， 当该驾 者倒车 （驾者切入倒车档）或左、 右转向 （驾者切入左、 右转方向灯） 时， 皆可分别在荧幕上显示当时的车后侧或车左、 右侧的影像画面， 但当驾者有 突发事件（动作）发生时， 却无法立刻切换画面以满足驾者的需要， 如： 驾 者在开启左 /右转向灯时， 因有需要而突然产生警示灯动作（如驾者转向后突 发现路边车位而欲马上抢进停车） ， 但此时画面却无法随着警示灯动作而立 即由左 /右侧画面切换至优先权较重要的警示灯动作， 即警示灯动作无法立即 取代转向灯动作； 又如驾者在倒车 （倒档） 时， 因有需要而欲观看车左侧影 像（如驾者想看车左侧是否有后来车以避免影响后来车的正常行进） ， 但此 时画面却无法随着左转灯动作而立即由倒车 （倒档） 画面切换至优先权较重 要的左转灯动作， 即转向灯动作无法立即取代倒车 （倒档）动作。
再言之， 现有车侧影像辅助系统的荧幕上一般只能显示与驾者当时动作， 即倒车或左、 右转向灯的开启操作， 同步的影像画面， 但当上述的动作解除 时， 荧幕上的影像画面即同步消失， 且无法再配合一般驾者的开车习惯而于 荧幕上优先或自动切换显示当驾者在解除上一动作之后最需要或最有用的画 面供驾者观看； 在此以路边停车格的停车或出车过程为例说明， 依一般驾者 的开车习惯及状况而言， 路边停车格的停车或出车无法一次动作即完成， 即 不可能以一次的倒车档就完成狭窄空间停车格的停车， 驾者往往须经过多次 的倒车及前进动作才停好， 而停车格的出车也常是相同情况； 然而目前使用 的车侧影像辅助系统， 在倒车档操作时， 荧幕上会显示当时的车后侧的影像 画面， 但当驾者解除倒车档时荧幕上的影像画面即同步消失， 且没有其他有 用的影像画面供仍处于停车过程中的驾者观看， 如车子要再前进时却无从得 知车前侧下方 （从驾驶座看不到处）是否有异物阻挡 （如前车是否设有往后 凸伸的挡泥板） ， 造成驾者前进时的困扰。 另， 有些谨慎的驾者会在停车过 程中同时开启警示灯号 （即左、 右向灯号同时开启） 以增加安全性， 此时目 前使用的车侧影像辅助系统可能就没有考虑到此种状况， 当然也就发挥不了 作用。 因此， 以目前汽车市场而言， 发展一车侧影像辅助系统， 使其不但安装 容易且适用各种车体安装以提升消费者接受度及市场性， 且更能减少因杂讯 干扰而发生误判的情形以提升判读准确度及增进使用效率， 确实有其需要。 发明内容
本发明主要目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 包含： 至少两个摄影机装置（camera )分别设置于车左、 右侧（或车后侧）等 不同位置供可分别撷取该对应车侧的影像并形成影像信号源而输出至一影像 信号源切换处理器； 一影像信号源切换处理器供藉由不同的灯号信号如倒车 灯号、 左或右向灯号或警示灯号当作启动信号源， 以自动切换选择并启动该 至少二个摄影机装置中至少一对应的摄影机装置， 并将该至少一对应的摄影 机装置所撷取该对应车侧的影像， 即接收该对应的摄影机装置所形成的影像 信号源， 输出并显示于一显示器装置的荧幕上而形成至少一画面； 其中该影 像信号源切换处理器包含一灯号信号判读处理器， 当任一灯号信号启动并输 入至该影像信号源切换处理器后， 该灯号信号判读处理器即在经过一预设的 临界时间点如 8毫秒（ 0.008秒）之后才开始判谭， 并持续进行判读一段预设 时间如至 300毫秒（即 0.3秒 )之后才输出判读结果以自动选择并启动所对应 的摄影机装置； 藉此， 不但可避免因其他杂讯的产生而发生误判的情形， 并 可准确地判读该灯号信号是否为单一的左 /右向灯号或一警示灯号 （即左右向 灯号为同步灯号） ， 藉以达成安装容易且适用各种车体安装， 并提升判读准 确度， 俾有利于提升消费者接受度及市场性， 并增进车侧影像辅助系统的使 用效率。

本发明又一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该影像信号源切换处理器进一步包含一信号输出优先权控制器 , 该信号 输出优先权控制器是依据启动灯号动作 （即灯号信号） 的重要性以预先设定 一优先权逻辑， 并通过该优先权逻辑以决定采用那一对应的车侧摄影机装置 供在荧幕上优先显示该对应车侧的影俸画面， 以使荧幕上所显示的影像画面 因而具有取代性和不被取代性的优先权处理功能； 其中该启动灯号动作 （即 灯号信号） 的重要性， 即灯号信号的优先权逻辑， 可依据一般驾者开车时配 合正确启动灯号的动作习惯加以设定， 如将优先权逻辑设定为： 警示灯动作 的重要性（优先权） 大于转向灯动作以使警示灯动作所对应显示的影像画面 可立即取代转向灯动作所对应显示的影像画面， 但若上述动作为反向操作时， 则为不可被取代性动作； 或转向灯动作的重要性（优先权）大于倒车 （倒档） 动作以使转向灯动作所对应显示的影像画面可立即取代倒车 （倒档） 动作所 对应显示的影像画面， 但若上述动作为反向操作时， 则为不可被取代性动作； 或左向灯和右向灯为同等重要（优先权相等） 以使左向灯和右向灯动作所对 应显示的影像画面可立即相互取代， 藉以使荧幕上所对应显示的车侧影像画 以符合一般驾者的开车习惯， 并增进车侧影像辅助系统的使用效率。
本发明另一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该信号输出优先权控制器除了依据一般驾者开车时配合正确启动灯号的 动作习惯以设定一优先权逻辑之外， 可在前一启动灯号动作 （灯号信号）解 除（消失） 而后一启动灯号动作 （灯号信号） 尚未产生时， 即在前、 后二灯 号信号之间的空档中， 进一步依据一般驾者的开车动作以预先设定一暂时性 优先权逻辑， 以在前一灯号信号解除而后一灯号信号尚未产生时能自动切换 选择并启动至少一摄影机装置以在荧幕上优先显示至少一较有用的影像画面 供驾者观看， 如当该前一灯号信号为倒车灯号且解除后， 此时可能是处于路 边停车格的停车或出车过程中， 此时即通过该暂时性优先权逻辑以自动切换 并启动该车左侧摄影机装置， 以使驾者能在倒车灯号 （前一灯号信号）解除 时可马上看到车左侧路况的影像画面， 以配合或辅助驾者开车习惯的不足， 并增进车侧影像辅助系统的使用效率。
本发明另一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该车前侧摄影机装置进一步设定于该信号输出优先权控制器所预设的暂 时性优先权逻辑之内， 以使该暂时性优先权逻辑增加一优先权的选择项， 如 当前一倒车灯号信号解除但后一灯号信号尚未产生 （即驾者并未切换至左转 向灯号以启动车左侧的摄影机装置） 时， 即可依据该暂时性优先权逻辑以自 动切换选择并启动该车前侧摄影机装置以于荧幕上立即显示车前侧的影像画 面供驾者观看， 以使驾者在解除倒车灯号并切换至前进档时， 即能马上观看 车前侧下方 （从驾驶座看不到处）是否有异物阻挡， 以增进驾车的安全性及 方便性及车侧影像辅助系统的使用效率。
本发明另一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该信号输出优先权控制器进一步可同时通过该优先权逻辑及暂时性优先 权逻辑的配合， 以决定采用那一对应的车侧摄影机装置供在荧幕上优先显示 该对应车侧的影像画面， 如路边停车的车辆准备出车并进入车道时， 驾者一 般是先倒车之后再换档前进， 则在倒车灯号 （前一灯号信号）解除而后一灯 号信号尚未产生 （即驾者尚未切换至左向灯号） 时， 即可通过该暂时性优先 权逻辑以自动切换选择并启动该车前侧摄影机装置以于荧幕上立即显示车前 侧的影像画面供驾者观看车前侧下方（从驾驶座看不到处）是否有异物阻挡， 待驾者准备左转前进入车道时， 则配合左向灯动作， 此时即通过该优先权逻 辑以自动切换并启动该车左侧的摄影机装置并所撷取的影像显示于荧幕上， 藉以配合或辅助驾者开车习惯的不足， 并增进车侧影像辅助系统的使用效率。
本发明另一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该车侧影像辅助系统进一步可配合一行车记录器 （EDR, Event Data Recorder )使用， 使一行车记录器（EDR )可通过连接埠以与该车侧影像辅助 系统连接， 以利用该车侧影像辅助系统的该至少一个摄影机装置（camera ) 10 ( 11、 12、 13至少其中一个摄影机装置）或进一步扩充设置的车前侧摄影机 装置以撷取并记录影像数据， 并可通过该车侧影像辅助系统的显示器装置， 如连接至该影像信号源切换处理器所设的一影像输入扩充端， 以显示该行车 记录器所记录的影像数据， 以达成一行车记录器 （EDR ) 的使用功能。 至于 利用目前影像记录方式的现有技术可以达成， 故在此不另再赘述。
本发明另一目的在于提供一种利用灯号信号启动的车侧影像辅助系统， 其中该车侧影像辅助系统进一步可配合一全球定位系统 （ GPS , global positioning system )使用， 使一全球定位系统（ GPS )可通过连接埠以与该车 侧影像辅助系统连接， 以利用该车侧影像辅助系统的显示器装置以显示该全 球定位系统（GPS )所提供的行车数据， 以达成一全球定位系统（GPS )的使 用功能。 或进一步配合一行车记录器（EDR, Event Data Recorder )使用， 并 同步将全球定位系统（ GPS )所提供的行车数据及车侧影像辅助系统的该至少 一个摄影机装置 （camera ) 10 ( 11、 12、 13 至少其中一个摄影机装置）或进 一步扩充设置的车前侧摄影机装置以撷取并记录影像数据， 并可通过该车侧 影像辅助系统的显示器装置以显示该行车记录器所记录的影像数据， 包含该 全球定位系统（GPS ) 所提供的行车数椐， 如： 日期、 时间、 全球定位座标、 车辆位移速度（时速）等， 以达成更具明确的记录和佐证的使用功能。
为了达到上述目的， 本发明提供了一种利用灯号信号启动的车侧影像辅 助系统， 包含： 至少两个车侧摄影机装置、 一启动信号源、 一影像信号源切 换处理器及一显示器装置， 其中：
.该车侧摄影机装置， 包括至少一车左侧摄影机装置设于车左侧位置及至 少一车右侧摄影机装置设于车右侧位置， 供分别撷取该对应车侧的影像并形 成影像信号源以输出至该影像信号源切换处理器；
该启动信号源， 由倒车灯号、 左向灯号、 右向灯号及警示灯号形成， 当 该倒车灯号、 左向灯号、 右向灯号及警示灯号中任一灯号启动时即形成该启 动信号源中一灯号信号， 该启动信号源再通过连接线将所产生的灯号信号输 出至该影像信号源切换处理器；
该影像信号源切换处理器， 通过该启动信号源所输入的灯号信号当作启 动信号源并形成一摄影机装置电源启动信号， 以自动切换选择并启动该摄影 机装置中至少一对应的摄影机装置以撷取该对应车侧的影像， 并将该至少一 对应的摄影机装置所撷取该对应车侧的影像输出并显示于该显示器装置的荧 幕上以形成至少一画面；
其中该影像信号源切换处理器包含一灯号信号判读处理器用以判读该灯 号信号为倒车灯号、 左向灯号、 右向灯号及警示灯号中那一灯号所形成； 其中当启动信号源中产生一灯号信号并输入至该影像信号源切换处理器 后， 该灯号信号判读处理器即在一设定的临界时间之后才开始判读， 并持续 进行一段预设的判读时间之后才输出判读结果以选择并启动所对应的摄影机 装置。
实施时， 该车侧摄影机装置进一步包含至少一个车后侧摄影机装置。 实施时， 该灯号信号判读处理器在经过 8 毫秒的临界时间之后才开始判 读， 并持续进行判读至 300毫秒之后才输出判读结果。

实施时， 该影像信号源切换处理器进一步包含一信号输出优先权控制器， 该信号输出优先权控制器依据倒车灯号、 左向灯号、 右向灯号及警示灯号等 各灯号信号的重要性， 预设一灯号的优先权逻辑， 以使优先权较大的灯号所 对应启动的摄影机装置所撷取的影像画面能立即取代优先权较小的灯号所对 应启动并撷取的影像画面， 以在荧幕上优先显示该优先权较大的灯号所对应 的车侧影像画面。
实施时， 当该灯号信号判读处理器已输出一判读结果为左向灯号信号、 右向灯号信号或警示灯号信号中的一种灯号信号且已对应启动至少一车侧摄 影机装置以撷取该车侧的影像并输出至于荧幕上显示至少一车侧画面时， 该 荧幕上所显示的车侧画面设定为保留一段持续显示时间， 又在该持续显示时 间内， 当产生另一优先权较大的灯号并对应启动至少一对应的摄影机装置以 撷取影像画面时， 该优先权较大的灯号所对应启动并撷取的影像画面即能立 即取代该优先权较小的灯号所对应启动并撷取的影像画面。
实施时， 该灯号的优先权逻辑设定为： 警示灯号的优先权大于转向灯号 以使警示灯号所对应启动并显示的影像画面能立即取代转向灯号所对应启动 并显示的影像画面， 但若上述动作为反向操作时则为不可被取代性动作； 又 转向灯号的优先权大于倒车 （倒档）灯号以使转向灯号所对应启动并显示的 影像画面能立即取代倒车 （倒档）灯号所对应启动并显示的影像画面， 但若 上述动作为反向操作时则为不可被取代性动作； 又左向灯号与右向灯号的优 先权相等以使左向灯号及右向灯号所对应启动并显示的影像画面可相互取 代。
实施时， 该信号输出优先权控制器进一步预设一灯号的暂时性优先权逻 辑， 以在前一灯号信号解除而后一灯号信号尚未产生时， 即自动切换选择并 启动一摄影机装置以在荧幕上优先显示该摄影机装置所撷取的影像画面 , 且 可停留一预设时间。

为使本发明更加明确详实， 将本发明的结构及其技术特征配合下列图示 详述如后二
参考图 1所示， 本发明的利用灯号信号启动的车侧影像辅助系统 1， 主要 包含： 至少两个车侧摄影机装置（camera ) 10、 一启动信号源 20、 一影像信 号源切换处理器 30及一显示器装置 40。
该至少两个摄影机装置 10主要包括至少一车左侧摄影机装置 12及至少 一车右侧摄影机装置 13分别设置于车左侧及车右侧等不同位置如图 5所示： 为方便说明本发明的使用功效， 在此使该摄影机装置 10更包含至少一个车后 侧摄影机装置 11设置于车后侧位置如图 5所示但不限制； 而利用该等摄影机 装置 11、 12、 13 , 可分别撷取该对应车侧的影像并形成影像信号源 101以输 出至该影像信号源切换处理器 30。
该启动信号源 20是由倒车灯号 201、 左向灯号 202、 右向灯号 203及警 示灯号 204 (即左右向灯号 202、 203为同步灯号）形成，即当该倒车灯号 201、 左向灯号 202、右向灯号 203及警示灯号 204其中任一灯号启动时（即灯开始 亮 （通电） ） 就可形成启动信号源 20中一灯号信号， 该启动信号源 20再藉 由连接线 21 将所产生的各种不同灯号信号输出至该影像信号源切换处理器 30。由上可知，本发明的启动信号源 20与现有技术如中国台湾省新型专利 TW M371134U1利用车体信号如档位信号或方向灯开关信号不同， 该现有技术是 为车体信号， 以产生一启动信号源。
该影像信号源切换处理器 30是通过该启动信号源 20所输入的不同的灯 号信号， 如倒车灯号 201、 左向灯号 202、 右向灯号 203及警示灯号 204, 当 作启动信号源并形成一摄影机装置电源启动信号 301 ,以自动切换选择并启动 该三个摄影机装置 10( 11、 12、 13 )的中至少一对应的摄影机装置 10( 11/12/13 ), 如倒车灯号 201可设计为自动切换启动该车后侧摄影机装置 11，左向灯号 202 可设计为自动切换启动该车左侧摄影机装置 12, 右向灯号 203可设计为自动 切换启动该车右侧摄影机装置 13 , 以分别撷取该对应车侧的影像， 并将该至 少一对应的摄影机装置 10 ( 11/12/13 )所撷取该对应车侧的影像， 即该对应的 摄影机装置 10 ( 11/12/13 )所形成的影像信号源 101 , 通过该影像信号源切换 处理器 30再输出至并显示于该显示器装置 40的荧幕 41上而形成至少一画面。
这样， 本发明利用灯号信号启动的车侧影像辅助系统 1 得容易地安装在 车上使用， 且适用于各种车体的安装使用， 有利于提升消费者接受度及市场 性。 至于用以启动该三个摄影机装置 10 ( 11/12/13 ) 的电源输入 70可包含一 次全部开启方式或一对一对应启动方式， 其中该一次全部开启方式是将该三 个摄影机装置 10 ( 11/12/13 )一次全部开启电源以形成开机状态但需再通过摄 影机装置电源启动信号 301 启动才开始撷取影像； 该一对一的对应启动方式 是通过摄影机装置电源启动信号 301 以一对一对应开启电源并同时开始撷取 影像； 该电源输入 70也可通过汽车电门启动信号 80以同时提供电源， 也可 搭配防盗器警报信号 90使用： 惟， 上述有关电源输入 70的启动方式及其应 用， 利用目前的电子技术可以达成， 且非本发明的主要特征， 故在此不另再 赘述。
本发明的影像信号源切换处理器 30更包含一灯号信号判读处理器 31 ,当 启动信号源 20中产生一灯号信号并输入至该影像信号源切换处理器 30后， 即藉由该灯号信号判读处理器 31以在一设定的临界时间之后， 如在灯号信号 输入之后以延迟 8毫秒（ 0.008秒） 当作临界时间， 而在经过该临界时间之后 才开始判读， 并持续进行一段预设的判读时间如至 300毫秒（即 0.3秒）之后 才输出判读结果以自动选择并启动所对应的摄影机装置， 用以判读该灯号信 号为倒车灯号 201、 左向灯号 202、 右向灯号 203或警示灯号 204 (即左右向 灯号 202、 203为同步灯号） 中的那一灯号所形成， 以提升判读灯号信号的准 确度， 并避免发生误判的情形。
一般车辆的灯号信号如倒车灯号 201、 左或右向灯号 202、 203及警示灯 号 204， 无论是否启动（亮灯）或关闭 （熄灭） ， 其相关的连结电路上仍难免 有其他的杂讯产生， 虽然一般杂讯的产生时间只有几毫秒， 一般不超过 8 毫 秒（0.008秒） , 会比一般灯号信号短， 但该杂讯仍会影响该灯号信号的判读。 又该警示灯号 204是左、 右向灯号 202、 203同时启动而视为同步灯号， 但该 左、 右向灯号 202、 203之间仍存在一时间差， 一般约在 0.15秒至 0.25秒之 间或更小； 因此， 本发明的该影像信号源切换处理器 30特别利用一灯号信号 判读处理器 31以产生一种特别的判读机制， 用以针对所输入的灯号信号进行 准确地判读。
参考图 1所示， 该警示灯号 204是左、 右向灯号 202、 203同时开启而为 同步灯号， 但实际上并非为完全的同步灯号， 即该左、 右向灯号 202、 203之 间仍存在一时间差， 一般约在 0.15秒至 0.25秒之间或更小， 因此若未考虑该 时间差， 则当驾者切换成警示灯号时， 该左、 右向灯号 202、 203中之一可能 先开启， 如左向灯号 202先亮灯而右向灯号 203慢亮灯（时间差为 0.15秒至 0.25秒或更小） , 此时影像信号源切换处理器 30可能先以该左向灯号 202当 作启动信号源 20的灯号信号， 即摄影机装置电源启动信号 301 , 而对应启动 该车左侧摄影机装置 12， 如此则发生误判的情形； 再而因右向灯号 203也接 着亮灯， 此时影像信号源切换处理器 30马上又以该右向灯号 203当作启动信 号源 20的灯号信号， 而对应启动该车右侧摄影机装置 13 , 如此则又发生误判 的情形， 造成荧幕 41上车左侧画面及车左侧画面快速切换的情形， 又如左向 灯号先亮灯而右向灯号慢亮灯（时间差约 0.15- 0.25秒或更小） ， 此时影像信 号源切换处理器可能先以该左向灯号当作启动信号源以对应启动该车左侧摄 影机装置以撷取车左侧的影像并输出且显示于荧幕上而形成车左侧画面， 再 而因右向灯号也亮灯， 但此时影像信号源切换处理器仍停留在左向灯号当作 启动信号源以对应启动该车左侧摄影机装置以撷取车左侧的影像并输出且显 示于荧幕上而形成车左侧画面， 造成荧幕上车左侧画面持续停留； 因此， 如 果将该警示灯号 204设定为同时启动多个摄影机装置 10如包含车后侧及车 左、 右侧等三个摄影机装置 11、 12、 13以撷取车侧三方向的影像并输出且显 示于荧幕 41上以形成三个次画面 （子画面） ， 则透过该灯号信号判读处理器 31可准确地判读该摄影机装置电源启动信号 301为警示灯号 204， 而不会发 生误判的情形。 因此该灯号信号判读处理器 31 可提升判读该启动信号源 20 的灯号信号， 即摄影机装置电源启动信号 301 , 的准确度， 相对提升本发明车 侧影像辅助系统 1的使用效率。
参考图 7, 以其中 （a ) 〜（h )各种情况为例， 进一步说明本发明的灯号 信号判读处理器 31的判读机制， 其中， 当任一信号， 包含启动信号源 20所 产生一灯号信号或其他杂讯， 输入该灯号信号判读处理器 31时， 可能产生下 歹' J ( a ) 〜（h )各种情况：
情况（a ) ： 当右向灯号产生一信号， 但该信号并未超过临界时间 8毫秒 ( 0.008秒） 即消失， 则判读为"非右向灯号信号" , 即判读结果输出为"无信 号" ， 也就是认为该信号为一般杂讯；
情况（b ) 、 ( c ) ： 当右向灯号产生一信号， 且该信号已延续超过临界 时间如 8毫秒（0.008秒） ， 则不论该信号是否延续超过一段判读时间如 300 毫秒（ 0.3秒 ) , 如情况（ b )未超过 300毫秒（ 0.3秒 ) 而情况（ c )超过 300 毫秒（0.3秒） ， 然由于在判读时间如 300毫秒（0.3秒） 内并未产生其他信 号， 故判读为"右向灯号信号"， 即判读结果输出为"右向灯号信号"； 其中， 灯 号信号的长短， 如情况（b ) 的信号短而情况（c ) 的信号长， 常随不同车款 或不同年代（新旧车或电路设备老化） 而不同；
情况（d ) : 当右向灯号产生一信号， 而该信号已延续超过临界时间如 8 毫秒（0.008秒）及判读时间如 300毫秒（0.3秒） ， 且在判读时间如 300毫 秒（0.3秒） 内又产生一左向灯号， 此时无论该左向灯号停留多久时间， 则判 读为"警示灯号信号"， 即判读结果输出为"警示灯号信号"；
情况（e ) ： 当左向灯号产生一信号， 但该信号并未超过临界时间 8毫秒 ( 0.008秒） 即消失， 则判读为"非左向灯号信号" , 即判读结果输出为"无信 号" , 也就是认为该信号为一般杂讯；
情况（f)、 ( g )： 当左向灯号产生一信号， 且该信号已延续超过临界时 间如 8毫秒（ 0.008秒） ， 则不论该信号是否延续超过一段判读时间如 300毫 秒（0.3秒） ， 如情况（f ) 未超过 300毫秒（0.3秒） 而情况（g )超过 300 毫秒（0.3秒） , 然由于在判读时间如 300毫秒（0.3秒） 内并未产生其他信 号， 故判读为"左向灯号信号" ， 即判读结果输出为"左向灯号信号"； 其中， 灯号信号的长短， 如情况（f)的信号短而情况（g )的信号长， 常随不同车款 或不同年代（新旧车或电路设备老化） 而不同；
情况（h ) : 当左向灯号产生一信号， 而该信号已延续超过临界时间如 8 毫秒（0.008秒）及判读时间如 300毫秒（0.3秒） 且在判读时间如 300毫 秒（0.3秒） 内又产生一右向灯号， 此时无论该左向灯号停留多久时间， 则判 读为"警示灯号信号"， 即判读结果输出为"警示灯号信号"。
由上可知， 藉由该灯号信号判读处理器 31的判读机制， 得准确地判读左 向灯号 202、 右向灯号 203或警示灯号 204 (即左右向灯号 202、 203为同步 灯号） ， 且不会因杂讯而发生误判的情形。 至于该灯号信号判读处理器 31的 电路设计或在显示器装置 40的荧幕 41上显示单一个主画面或多个次画面（子 画面） ， 利用目前的电子技术可以达成， 因此在此不另再赘述。
另， 由于左向灯号 202及右向灯号 203的亮灯型态皆为间隔式闪烁型态， 即一般通称 "一亮一灭" 的循环式闪烁亮灯型态， 其中每一 "亮" 、 "灭（不 亮） " 之间存在一时间差， 一般而言该时间差是不超过 2秒； 因此在上述图 7所示的情况（b ) 、 （c ) 、 （d )或（f) 、 （g ) 、 （h ) 中， 当该灯号信号 判读处理器 31 已输出一判读结果为 "左向灯号信号" 或"右向灯号信号或"警 示灯号信号" 中的一种灯号信号， 且通过该影像信号源切换处理器 30也已对 应启动至少一车侧摄影机装置以撷取该车侧的影像并输出至于荧幕 41上显示 至少一车侧画面时， 则该荧幕 41上所显示的车侧画面可设定为保留一段持续 显示时间且至少超过灯号 "一亮一灭" 的时间差， 如设定该持续显示时间为 至少 2秒的时间， 以使该荧幕 41上的车侧画面能维持稳定的显示状态， 藉以 避免该荧幕 41上的车侧画面随着该灯号（202/203 )的 "一亮一灭" 闪烁亮灯 型态而呈现跳动的画面； 也就是当该灯号 （202/203 ) —经判读并启动而显示 于荧幕 41上后， 即可自动持续保留至少 2秒时间， 而在该 2秒时间内该灯号 (左向灯号 202或右向灯号 203 )一定会再经过另一次 "一亮一灭" 的循环， 并再进行该灯号的另一次的判读工作； 如此该荧幕 41上所显示的车侧画面得 保留连续状态的稳定的画面， 使其不随灯号（202/203 )的 "一亮一灭" 而跟 着跳动， 除非在该持续显示时间 （如 2秒时间） 内， 驾者又切换变更灯号并 被该灯号信号判读处理器 31判读成立为另一有效的灯号时， 该荧幕 41上所 显示的车侧画面才会切换成该另一有效的灯号所对应启动的车侧摄影机装置 所擁取的车侧画面。
参考图 2所示， 本发明的利用灯号信号启动的车侧影像辅助系统 1 中， 其中该影像信号源切换处理器 30进一步包含一信号输出优先权控制器 32。该 信号输出优先权控制器 32主要是依据启动灯号动作， 即倒车灯号 201、 左向 灯号 202、右向灯号 203及警示灯号 204其中任一灯号所产生的灯号信号（亦 即摄影机装置电源启动信号 301 ) , 的重要性， 预先设定一优先权逻辑， 供可 藉由该优先权逻辑决定采用那一对应的车侧^摄影机装置 10 ( 11/12/13 ) , 以在 荧幕 41上优先显示该对应车侧的影像画面， 使荧幕 41上所显示的影像画面 因而具有取代性和不被取代性的优先权处理功能； 其中该启动灯号动作 （即 灯号信号） 的重要性， 即灯号信号的优先权逻辑， 可依据一般驾者开车时配 合正确启动灯号的动作习惯加以设定； 以下所述为本发明的优先权逻辑的一 较优选实施例但并非用来限制本发明， 该优先权逻辑可设定为： 将警示灯动 作（警示灯号 204 )的重要性（优先权）视为大于转向灯动作（左、 右向灯号 202、 203 )以使警示灯号 204所对应显示的影像画面可立即取代转向灯动作所 对应显示的影像画面， 但若上述动作为反向操作时， 则为不可被取代性动作； 又将转向灯动作（左、 右向灯号 202、 203 )的重要性（优先权）视为大于倒车 (倒档）动作（倒车灯号 201 )以使转向灯动作所对应显示的影像画面可立即 取代倒车 （倒档）动作所对应显示的影像画面， 但若上述动作为反向操作时， 则为不可被取代性动作； 又将左向灯和右向灯（左、 右向灯号 202、 203 )视 为同等重要（优先权相等）以使左、 右向灯号 202、 203所对应显示的影像画 面可立即相互取代； 这样， 荧幕 41上所显示的车侧影像画面即能根据上述的 开车习惯， 并增进车侧影像辅助系统的使用效率。 但是， 上述各种灯号动作 的重要性的区别， 如警示灯动作的重要性大于转向灯动作、 转向灯动作的重 要性大于倒车 （倒档） 动作或左向灯和右向灯为同等重要的动作等， 得视为 本发明的优先权逻辑中一种设定方式但非用来限制本发明， 也就是车侧影像 辅助系统的制造商或使用者可另设定不同的优先权处理逻辑， 如依个人启动 灯号的操作习惯或另行设定个人化的优先权处理逻辑。
又该信号输出优先权控制器 32除了预设上述的优先权逻辑之外， 进一步 可在前一启动灯号动作 （灯号信号）解除（消失） 而后一启动灯号动作 （灯 号信号） 尚未产生时， 即在前、 后两灯号信号之间的空档中， 再预设一暂时 性优先权逻辑， 藉以在前一灯号信号解除而后一灯号信号尚未产生时， 能依 驾者需要而自动切换选择并启动至少一摄影机装置 10 ( 11/12/13 ) 以在荧幕 41 上优先显示至少一较有用的影像画面供驾者观看， 如当该前一灯号信号为 倒车灯号 201 且解除后， 此时可能是处于路边停车格的停车或出车过程中， 此时， 不论驾者是否切换至左右灯号， 即通过该暂时性优先权逻辑以自动切 换并启动该车左侧摄影机装置 12， 以使驾者能在倒车灯号 201 (前一灯号信 号）解除时可马上看到车左侧路况的影像画面， 以增进车侧影像辅助系统的 使用效率。
另， 由于上述的 "暂时性优先权逻辑" 是以前一灯号信号解除后， 即自 动切换预设的对应车侧摄影机并撷取影像画面， 故该自动切换且停留时间是 以预设值为准， 例如： 5秒或 10秒或依使用者习惯去设定。
另， 由于左向灯号 202及右向灯号 203的亮灯型态皆为间隔式闪烁型态， 即一般通称 "一亮一灭" 的循环式闪烁亮灯型态， 其中每一 "亮" 、 "灭（不 亮） " 之间存在一时间差， 一般而言该时间差是不超过 2秒； 因此， 当荧幕 41上所显示的车侧影像画面已根据该信号输出优先权控制器 32所设定的优先 权逻辑以优先显示其中优先权相对较大的影像画面时， 则该荧幕 41上所显示 的车侧画面可设定为保留一段持续显示时间且至少超过灯号 "一亮一灭" 的 时间差， 如设定该持续显示时间为至少 2秒的时间如为 5-10秒， 且其可随个 人需要而设定， 以使该荧幕 41上的车侧画面能维持稳定的显示状态， 以避免 该荧幕 41上的车侧画面随着该灯号（202/203 )的 "一亮一灭" 闪烁亮灯型态 而呈现跳动的画面； 也就是当该灯号（202/203 )—经判读并启动而于荧幕 41 上一显示画面后， 即可自动持续保留至少 2秒时间如为 5-10秒， 除非在该持 续显示时间 （如 5-10秒时间） 内， 又产生另一优先权相对较大的影像画面， 此时即可立即取代该保留一段持续显示时间的原来画面。
进一步说明该信号输出优先权控制器 32的作用功效如下： 基本上， 该倒 车灯号 201、 左向灯号 202、 右向灯号 203及警示灯号 204中任一灯号所产生 的灯号信号，即摄影机装置电源启动信号 301，是被设定为一优先权灯号信号， 即该信号输出优先权控制器 32只要接收到该倒车灯号 201、 左向灯号 202、 右向灯号 203及警示灯号 204中任一灯号信号， 此时不论该荧幕 41在显示任 何其他影像画面如播放一般电视画面， 可立即被取代为该灯号信号所对应的 车侧影像画面； 再而， 该信号输出优先权控制器 32 又针对该启动信号源 20 的各种灯号信号之间， 进一步设定一优先权次序 （即优先权逻辑） ， 如上所 述： 将警示灯号 204的优先权视为大于左、 右向灯号 202、 203 且将左、 右向 灯号 202、 203 的优先权又视为大于倒车灯号 201且将左、右向灯号 202、 203 视为同等优先权， 则只要驾者切换至优先权较大的灯号， 该优先权较大灯号 所对应显示的影像画面即可马上取代优先权较小灯号所对应显示的影像画 面， 使荧幕 41上所显示的影像画面能更确切地配合驾者的开车习惯， 也就是 荧幕 41上所显示的影像画面能正好是驾者当时最需要或最有辅助作用的车侧 影像画面； 更而， 该信号输出优先权控制器 32又进一步设定一暂时性优先权 次序 （即暂时性优先权逻辑） ， 使驾者在解除前一灯号如倒车灯号 201 之后 却忘了切换至另一灯号如左向灯号 202 (也可能是个人开车习惯不同所致） ， 此时藉由该暂时性优先权逻辑即可自动切换并启动该车左侧摄影机装置 12， 以使驾者能在倒车灯号 201 (前一灯号信号）解除时马上可看到车左侧路况的 影像画面， 以增进车侧影像辅助系统的使用效率， 并辅助个人开车习惯的不 足。
另， 由于上述的 "暂时性优先权逻辑" 以前一灯号信号解除后， 即自动 切换预设的对应车侧摄影机并撷取影像画面， 因此该自动切换且停留时间以 预设值为准， 例如： 5秒或 10秒或依使用者习惯去设定。
参考图 1所示， 本发明利用灯号信号启动的车侧影像辅助系统 1 中， 该 车侧摄影机装置 10进一步包含一车前侧摄影机装置 14设置于车前侧位置如 图 6所示， 并将该车前侧摄影机装置 14设定于该信号输出优先权控制器 32 所预设的暂时性优先权逻辑的运作功能之内， 以使该暂时性优先权逻辑增加 一优先权的选择项， 如当前一倒车灯号 201 解除但后一灯号尚未产生， 即驾 者并未切换至左向灯号 202以启动车左侧的摄影机装置 12时， 即可依据该暂 时性优先权逻辑以自动切换选择并启动该车前侧摄影机装置 14 以于荧幕 41 上立即显示车前侧的影像画面供驾者观看， 以使驾者在解除倒车灯号 201 并 切换至前进档时， 即能马上观看车前侧下方 （从驾驶座看不到处）是否有异 物阻挡， 以增进驾车的安全性及方便性及车侧影像辅助系统的使用效率。
另外， 由于上述的 "暂时性优先权逻辑" 以前一灯号信号解除后， 即自 动切换预设的对应车侧摄影机并撷取影像画面， 因此该自动切换且停留时间 以预设值为准， 例如： 5秒或 10秒或依使用者习惯去设定。 该信号输出优先权控制器 32进一步可同时通过上述的该优先权逻辑及暂 时性优先权逻辑的配合， 以决定采用那一对应的车侧摄影机装置 10 ( 11/12/13/14 )供在荧幕 41上优先显示该对应车侧的影像画面， 如路边停车 的车辆准备出车并进入车道时， 驾者一般是先倒车之后再换档前进， 则在倒 车灯号 201 (前一灯号信号 )解除而后一灯号信号尚未产生（即驾者尚未切换 至左向灯号 202 )时， 即可藉由该暂时性优先权逻辑以自动切换选择并启动该 车前侧摄影机装置 14以于荧幕 41上立即显示车前侧的影像画面供驾者观看 车前侧下方 （从驾驶座看不到处）是否有异物阻挡， 待驾者准备左转前进入 车道时， 则再配合左向灯号 202 的动作， 此时即藉由该优先权逻辑以自动切 换并启动该车左侧摄影机装置 12并荧幕 41上显示车左侧影像画面， 藉以配 合或辅助驾者开车习惯或其不足处， 并增进车侧影像辅助系统的使用效率。
另外， 由于上述的 "暂时性优先权逻辑" 以前一灯号信号解除后， 即自 动切换预设的对应车侧摄影机并撷取影像画面， 因此该自动切换且停留时间 以预设值为准， 例如： 5秒或 10秒或依使用者习惯去设定。
参考图 3所示， 本发明的利用灯号信号启动的车侧影像辅助系统 1 , 进一 步可配合一行车记录器（EDR， Event Data Recorder ) 50使用； 该行车记录器 ( ED ) 50可藉连接埠 501以与该车侧影像辅助系统 1的该影像信号源切换 处理器 30连接， 藉以利用该车侧影像辅助系统 1 的该至少一个摄影机装置 ( camera ) 10 ( 11、 12、 13至少其中一个以上摄影机装置）及 /或进一步扩充 设置的车前侧摄影机装置 14以撷取并记录该影像数据； 又该影像信号源切换 处理器 30更可扩充设置一影像输入扩充端 33如图 1-图 4所示， 使行车记录 器（EDR ) 50能进一步与该影像信号源切换处理器 30连接， 即连接至该影像 信号源切换处理器 30所设的影像输入扩充端 33 ,供可通过该车侧影像辅助系 统 1的显示器装置 40以在荧幕 41上显示该行车记录器 50所记录的影像数据， 达成一行车记录器（EDR ) 的使用功能。 至于影像记录技术是单路录影或四 路 (含以上)录影或四路 (含以上)合一后录影， 利用目前影像记录方式的现有技 术可以达成， 故在此不另再赘述
参考图 4所示， 本发明的利用灯号信号启动的车侧影像辅助系统 1 , 其进 一步可配合一全球定位系统（GPS, global positioning system ) 60使用； 该全 球定位系统（GPS ) 60可藉连接埠 601以与该车侧影像辅助系统 1的影像信 号源切换处理器 30连接， 如连接至该影像信号源切换处理器 30所设的影像 输入扩充端 33 , 藉以利用该车侧影像辅助系统 1 的显示器装置 40以在荧幕 41 上显示该全球定位系统（GPS )所提供的行车数据， 达成一全球定位系统 ( GPS )的使用功能。或进一步配合一行车记录器（ EDR, Event Data Recorder ) 使用， 并同步将全球定位系统（GPS )所提供的行车数据及车侧影像辅助系统 的该至少一个以上摄影机装置（camera ) 10 ( 11、 12、 13 至少其中一个摄影 机装置）或进一步扩充设置的车前侧摄影机装置以撷取并记录影像数据， 并 可藉由该车侧影像辅助系统的显示器装置以显示该行车记录器所记录的影像 数据， 包含该全球定位系统（GPS )所提供的行车数据， 如： 日期、 时间、 全 球定位座标、 车辆位移速度（时速） 等， 以达成更具明确的记录和佐证的使 用功能， 至于影像记录技术是单路录影或四路 (含以上)录影或四路 (含以上)合 一后录影， 乃利用目前影像记录方式的现有技术可以达成， 故在此不另再赘 述。

3、 本发明的影像信号源切换处理器 30进一步包含一信号输出优先权控 制器 32, 其依据启动灯号动作， 即倒车灯号 201、 左向灯号 202、 右向灯号
