With the APX RS, frame rates from 50 FPS to 3,000 FPS allows for recording of image using the full resolution of 1024 x 1024 pixels of the imaging sensor.

  • Page 43: Selecting Resolution

    FASTCAM-APX RS Hardware Manual 3.3. Selecting Resolution The APX RS has a high-speed mega-pixel imaging sensor with a full resolution of 1024 x 1024 pixels in its imager. It can produce a high-density image of 1,000,000 pixels in full resolution operation. Also, depending on the needs from each recording application, it can record at higher speeds by limiting the image resolution, or can record for a longer duration by reducing the amount of data of each of captured frames.

  • Page 44: Selecting Shutter Speed

    FASTCAM-APX RS Hardware Manual 3.4. Selecting Shutter Speed The APX RS’s electronic shuttering system makes it possible to control the exposure time within a frame regardless of the current frame rate. By using an exposure time that is shorter than the frame time determined by the frame rate (i.e. 1/frame rate sec.), you can capture events taking place at an extremely high speed as a still image without blurring effect.
  • Page 45 FASTCAM-APX RS Hardware Manual 3.4.2. Switching Shutter Modes By switching between MODE 1 and MODE 2 in the [SHUTTER MODE] menu, you can change the mode of shutter speed setting as follows: MODE 1:The shutter speed is automatically set to 1/(frame rate) sec when the frame rate is changed.

  • Page 46: Selecting Trigger Mode

    FASTCAM-APX RS Hardware Manual 3.5. Selecting Trigger Mode The APX RS has several different modes of triggering to meet the particular needs of capturing instantaneous events of varied nature. This section discusses how each of the trigger modes works. First, the procedure to select a trigger mode is shown, and then how each trigger mode works is discussed.

  • Page 47: Start Mode

    FASTCAM-APX RS Hardware Manual 3.5.1. START Mode In the START trigger mode, the camera starts recording at the moment the REC key is pressed and continues recording until the memory is full, and automatically stops recording. This mode is useful when you know for sure when the anticipated event will occur.

  • Page 48: Center Mode

    FASTCAM-APX RS Hardware Manual 3.5.2. CENTER Mode In the CENTER trigger mode, the camera records the target event in the same number of frames before and after the trigger. It is useful when you are interested in the scenes of before and after a particular event. If your camera has a recording capacity of two seconds, the camera records the scenes in the same number of frames (1024 frames –...

  • Page 49: End Mode

    FASTCAM-APX RS Hardware Manual 3.5.3. END Mode The END trigger mode records the images of a target event right before the REC key is pressed. This mode is useful when it is hard to know when your target event will take place.

  • Page 50: Manual Mode

    FASTCAM-APX RS Hardware Manual 3.5.4. MANUAL Mode In the MANUAL trigger mode, the camera records scenes before and after the REC key is pressed. Unlike the CENTER mode, however, the numbers of frames to record before and after a trigger can be preset differently. For a camera with a recording capacity of two seconds, for example, record durations of 0.5 seconds before and 1.5...
  • Page 51 FASTCAM-APX RS Hardware Manual Now set the numbers of frames before and after a trigger. Using the U-D and L-R cursor keys, up or down to increase or decrease the number, and left or right to jump the digit position, set a number. If you set the number for [–FRAME] as shown below, for example, the number for [+FRAME] is automatically set depending on the total number of frames available for recording.

  • Page 52: Random Mode

    FASTCAM-APX RS Hardware Manual 3.5.5. RANDOM Mode In the RANDOM trigger mode, the camera records in its memory a preset number of frames of images every time a trigger is given. This mode is useful to record images of events that take place at an unpredictable timing with output of a trigger signal. The number of frames to record at each trigger can be set any number from 1 (one) up to the total number of available frames in the memory.
  • Page 53 FASTCAM-APX RS Hardware Manual When you are done, press the ENTER key key to enter the settings. Now you should see the number of frames to record at each trigger as [RANDOM 20 FR] in the upper left area of the screen as shown below, where the number of frames to record at each trigger is 20.

  • Page 54: Random Reset Mode

    FASTCAM-APX RS Hardware Manual 3.5.6. RANDOM RESET Mode This section describes the principle of operation of the RANDOM RESET mode in comparison with the RANDOM and START modes. To simply put it, the RANDOM RESET mode is a mode of recording operation that has been devised to improve the accuracy of temporal relationship between the timing of trigger input and that of start of recording by resetting the recording timing, i.e.

The camera records in the memory the preset number of frames of images before and after the event, and stands by for a next trigger. In addition to the REC key on the keypad, contact or TTL signals from external trigger input terminals can be used to trigger the camera in the RANDOM mode (see Section 3.10 External...

  • Page 58: Random Manual Mode

    FASTCAM-APX RS Hardware Manual 3.5.8. RANDOM MANUAL Mode In the RANDOM MANUAL trigger mode, the camera records in the memory a preset number of frames of images at each trigger, as in the case with the RANDOM CENTER mode. The difference is that the RANDOM MANUAL allows for any number of frames to be recorded before and after a trigger, while the RANDOM CENTER mode records the same number of frames before and after a trigger.
  • Page 59 FASTCAM-APX RS Hardware Manual The meaning of each item is as follows: -FRAME Number of frames to record BEFORE a trigger. +FRAME Number of frames to record AFTER a trigger. TOTAL FRAME Total number of frames to record at a trigger.
