| abstract |
A test device to detect a detection object of a microfluidic device and a control method thereof are provided. The test device includes a light emitting element configured to emit light onto the microfluidic device, a light receiving element configured to capture an image of the detection object through light emitted from the light emitting element, and a controller configured to determine a signal value of a predetermined area of the image of the detection object, and adjust an exposure level of the light receiving element according to a difference between the signal value and a predetermined target value. |
