ex2) When you change the display mode, or delay of the monitor to increase or decrease?.

This app is good at applications to estimate the relative delay. This app is not intended to strictly measure the delay, it is an auxiliary tool for only estimate the extent of the simple delay.

Using the LCD in advance the exact delay time is known in order to investigate the conditions of the internal delay in the measurement environment using this app, the accuracy of the delay time estimated from the measurement data probably can be improved.

If there are 7 shots of 1 frame delay, 2 shots of 2 frame delay, and 1 shot of 1 frame delay, delay is estimated to average 1.4 frame.

We will recommend the technique to investigate the video movie in the frame-by-frame.Įx) Please examine 10 shots captured video. Therefore, in order to increase the accuracy of estimation of the delay, please statistical processing a large number of data. In principle, the delay time which can be read from one of the image will be an integral multiple of 1 frame.Faster shutter speed shooting equipment is recommended.Higher performance terminal is recommended.The option menu also opens on the screen tap.The text can be entered from the setting item of the option menu.By inputting the mode setting name etc of the monitor and displaying it, confusion can be prevented at the time of confirming the video later.Input text can be displayed in yellow in the center of the screen.In that case, since the display position of the square marker is skipping, delay measurement may be affected in the image judgment. Low spec terminal or GC causes Lost Frame.Lost frame count per 60 frames will be displayed in red in the middle right of the screen.In this case, app might draw the same frame. App shows “*” mark on fps, and works at the highest frame rate possible drawing.

When the terminal can not update drawing in the refresh rate or returns wrong refresh rate value, app works with an guess mode.Simply, the synchronization is performed, by utilizing the buffer blocking of SurfaceView.Basically it works with the refresh rate of the terminal.Frame rate will be displayed in blue in the middle left side of the screen.In fact, it is the blocking time of the multi-buffering. The number displayed in the square marker is an internal processing time.Shooting the screen of the LCD and the screen of terminal in the same photo, and by counting the displacement of the frame on the image, you can estimate delay frame of the LCD. If there is a delay, square marker will be displayed on the delayed position. If delay is zero on the LCD, you will see a square marker in the same position as the screen of the terminal.

12 white square markers disposed around the screen, are displayed sequentially in a clockwise direction for each frame(5 laps at 60 frames).Shooting devices such as digital cameras.

An Android terminal with HDMI output function.

By counting the displacement of the frame on the image, you can estimate delay frame of the LCD.

Shooting the screen of the LCD and the screen of terminal in the same photo by digital camera etc.

Connect the terminal and the LCD with an HDMI cable, and start app.

You can measure LCD’s delay by using terminal with HDMI output function.
