CROSS-REFERENCE TO RELATED APPLICATION

This application is a national stage application of PCT/KR2018/006691 filed on Jun. 14, 2018, which claims priority of Korean patent application number 10-2017-0146479 filed on Nov. 6, 2017. The disclosure of each of the foregoing applications is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure relate to a technology for synchronizing image information generated by a plurality of image sensors.

BACKGROUND ART

An image sensor may refer to a device for converting an image seen by user's eyes into electric signals using a photoelectric device, converting the electric signals into digital signals, and outputting the digital signals as image data.

Different delays may occur in image data output from the image sensor due to a structure of the image sensor or a difference in transmission path of digital signals, such that the output image data may not be synchronized by a reception end. As a result, image information acquired at different times is used, resulting in acquisition of incorrect information.

DISCLOSURE

Technical Problem

Various embodiments of the present disclosure are directed to providing an image synchronization device and an image information generation apparatus including the same that substantially obviate one or more problems due to limitations and disadvantages of the related art.

The embodiment of the present disclosure relates to an image synchronization device for synchronizing image information provided from a plurality of image sensors, and an image information generation apparatus including the same.

Technical Solution

In accordance with an embodiment of the present disclosure, an image synchronization device includes: a light emitting source configured to emit light at intervals of a predetermined time; a sampling phase calibration circuit configured to calibrate a sampling phase of each of the first image sensor and the second image sensor on the basis of a light emitting timing of the light emitting source; and a delay calibration circuit configured to generate delay information on the basis of a result of comparison between first image information transmitted from the first image sensor and second image information transmitted from the second image sensor. The first image information is obtained when the first image sensor performs sensing and sampling of a light emitting signal of the light emitting source, and the second image information is obtained when the second image sensor performs sensing and sampling of a light emitting signal of the light emitting source.

In accordance with an embodiment of the present disclosure, an image information generation apparatus includes: a first image sensor and a second image sensor configured to respectively generate first image information and second image information; an image synchronization device configured to control the first image sensor and the second image sensor to respectively generate the first image information and the second image information using a light emitting source that emits light at intervals of a predetermined time, and synchronize a sampling phase of each of the first image sensor and the second image sensor with a light emitting timing of the light emitting source on the basis of the first image information received from the first image sensor and the second image information received from the second image sensor; and an image processor configured to process the first image information transmitted from the first image sensor having the synchronized sampling phase and the second image information transmitted from the second image sensor having the synchronized sampling phase.

In accordance with another embodiment of the present disclosure, an image information generation apparatus includes: a first image sensor and a second image sensor configured to respectively generate first image information and second image information; an image information storage circuit configured to store the first image information and the second image information; an image synchronization device configured to control the first image sensor and the second image sensor to respectively generate the first image information and the second image information using a light emitting source that emits light at intervals of a predetermined time, and generate delay information between the first image information and the second image information on the basis of a result of comparison between the first image information and the second image information; and an image processor configured to process the first image information and the second image information on the basis of the delay information.

It is to be understood that both the foregoing general description and the following detailed description of the present disclosure are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Advantageous Effects

As is apparent from the above description, the embodiments of the present disclosure may synchronize image information transmitted from a plurality of image sensors.
