[0026] figure 1 An outline of the configuration of a robot device using an image pickup device (or a production system using a robot) according to the first embodiment is exemplified. figure 2 is a flowchart illustrating the flow of image capturing control according to the present embodiment.

[0027] exist figure 1 , the workpiece 9, which is a moving object whose image is captured according to the present embodiment, is held by the manipulator 81 at one end of the manipulator 8 and transported in the transport space 30 indicated by the arrow 30a. The transport space 30 is, for example, a transport path through which the workpiece 9 is transported by a robot device (or a production system using a robot) to a next working position or an inspection position. While the workpiece 9 is being transported, an image of the workpiece 9 is captured by the image pickup device 1 when the workpiece 9 is at a predetermined image capturing position in the transport space 30 .

Abstract

An image capturing control method and an image pickup apparatus are disclosed. An image of a work is formed such that the image moves in a fixed direction across an image sensing area of an image sensor. The image of the work is captured by the image sensor when it is at an image capture position, and image data thereof is output in a predetermined output format. The image sensor has an extraction area having a small image size or a small pixel density and is located on a side of an image sensing area of the image sensor from which the moving object enters the image sensing area. When it is detected in this extraction area that the object has arrived at a preliminary detection position located before the image capture position, the mode of the image sensor is switched such that image data is output in the output format, and the image data is output in this output format.

Description

technical field [0001] The present disclosure relates to an image capture control method and an image pickup device, and more particularly, to a technique for controlling a process of forming an image of a moving object so that the image of the moving object moves in a fixed direction in an image sensing area of ​​an image sensor, using The image sensor captures an image of a moving object at an image capture position, and image data of the captured image is output from the image sensor in a predetermined output format. Background technique [0002] Conventionally, it is known in a production line or the like to use transport units such as robots, belt conveyors, etc. to transport workpieces such as products or components to work or inspection positions where the workpieces are to be assembled or inspected. In many cases, workpieces that are objects of interest are transported in arbitrary poses. In general, after a work piece arrives at a work location, the pose or phase o...
