Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/199687
Kind Code:
A1
Abstract:
The present invention provides an imaging device which enables a reduction in inspection time and an increase in throughput without an omission of an image.
Provided is an imaging device, wherein an imaging element 1 captures an image and outputs the image at a high imaging frame rate, a memory unit 3 stores image data, a video signal processing unit 4 reads the image data from the memory unit 3 at a transmission frame rate lower than the imaging frame rate, and performs signal processing, an output interface unit 5 outputs the image data to the outside at the transmission frame rate, and when an imaging start signal is inputted from the outside, a control unit 6 outputs, to the imaging element 1, an exposure period signal giving an instruction to capture a predetermined number of frames and write the image data into the memory unit 3, outputs, to the video signal processing unit 4, an instruction to output video data from the memory unit 3 at the transmission frame rate, outputs, to an external device, an imaging period signal indicating an imaging period during which the predetermined number of frames are captured, and reports the end of the imaging period to the external device.
