Photo finish stopwatch v1.10 (Paid) APK

Use professional photo finishing technology in your smartphone. Use the slit camera technique to measure the finish time of all race events with great accuracy. Obtain an image to determine the winner with great precision.

The Photo Finish stopwatch allows you to:
Measure finish time with an accuracy of 0.05 s
Determine the winner of the race.
Save an image to prove the winner and the result.
Share this photo with your friends.

How it works
App took a series of split photos of the finish line.
Each photo frame has a time stamp with the precise time of the stopwatch.
When on the frame you see that the finish line is crossed. This means that the timestamp of a specific frame defines the end time.

Instruction
Point a camera at the finish line. The solid line must point to the finish. The dotted line shows the border of the frame.
Pick the right direction.
Select the correct frame width.
Start the stopwatch at the start of the race.
When the winner approaches the finish line, start recording.
When the athlete has crossed the finish line, stop recording.
Find the frame when the winner crosses the finish line. The time stamp on the cursor line indicates the precise result.

Direction
The application uses the split photo technique. It combines a series of images with the resulting image in chronological order. The scale at the top of the resulting image shows an approximate chronology of the stopwatch. The numbers at the bottom of each frame indicate the milliseconds of the timestamp.
Depending on how the winner approaches the finish line, it is more comfortable to combine the frames in “left to right” or “right to left” order.

Frame width.
This setting depends on the distance between the camera and the finish line, the speed of the athlete. If the camera is too close or the athlete is fast, they may cross the area of ​​the frame too quickly to get a clear image. It is therefore preferable to increase the width of the image. On the other hand, the size of the resulting image is limited. If the frame is too wide, you will have less time to record the winner’s result.

Precision.
The estimated accuracy of the stopwatch is approximately 0.05 s. It mainly depends on the frame rate of the device’s camera. Standard phones support 30 fps. 1/30 = 0.033 ms. In addition, if the performance of the device is poor, the application may skip some images.
