Abstract: To provide an image-capturing system capable of maintaining high analysis accuracy while reducing the amount of data related to image acquisition with a simple method. In order to achieve the object, the image-capturing system includes an image-capturing device configured to acquire image data of a subject, and an image-capturing control device configured to control image acquisition by the image-capturing device. The image-capturing control device includes a difference extraction means configured to extract difference data on the basis of any two image data items acquired by the image-capturing device, a change amount extraction means configured to extract change amount data on the basis of any two difference data items extracted by the difference extraction means, and a condition change means configured to change an image acquisition condition in the image-capturing device on the basis of the change amount data extracted by the change amount extraction means.

Abstract: An optical pickup device includes a frame F in which an integrated optical unit equipped with a semiconductor laser diode is incorporated and a flexible substrate F having a short-circuit wiring pathway connecting two connectors and a driving circuit. The short-circuit wiring pathway is connected to the integrated optical unit and the driving circuit at a minimum distance through the connector in such a manner that the flexible substrate F is incorporated so as to be wound along the frame F. Consequently, recording processing and the like can be stably performed.
