Controller and control method for electronic instrument

本发明提供一种能够以较少的部件，实现伺服控制的电子仪器控制器及电子仪器的控制方法。电子仪器控制器(50)包括：对具有有效象素区和虚拟象素区的图像传感器(22)进行控制的图像传感器控制器(60)；对装有驱动图像传感器(22)的滑动架(20)的驱动装置(30)进行伺服控制的伺服控制器(80)。伺服控制器(80)根据用图像传感器(22)的虚拟象素区(一个或多个光接收元件)读取的伺服控制信息(速度控制用、初始位置检测用)进行伺服控制。根据多个速度控制用的伺服控制信息，按照速度控制范围进行相应的伺服控制。也可以根据图像传感器(22)以及装在同一个滑动架(20)上的传感器，读取的伺服控制信息，进行伺服控制。 An electronic device controller includes an image sensor controller that controls an image sensor having an effective pixel region and a dummy pixel region, and a servo controller that performs servo control on a drive device that drives a carriage on which the image sensor is mounted. The servo controller performs the servo control based on servo control information (for speed control, initial position detection) read by some or all of the dummy pixel region of the image sensor. Alternatively, the servo control may be performed based on servo control information read by one or more separate sensors mounted on the carriage with the image sensor. Moreover, speed servo control may be performed according to speed control ranges based on servo control information for each speed range.
