QHY174M explains the process of displaying pictures after exposure.
2018 年 10 月 17 日

      First of all, QHY174M camera does not have a real single-frame mode.
        The existing single-frame mode actually starts the continuous mode, and the picture is extracted during the continuous mode process.

        Combined with the attached picture, when the camera's single frame mode is clicked on the camera button for the first time,
        it actually starts the continuous mode, starts exposure, waits for the end of exposure time, gets the picture and displays,
        the exposure time display is equal to the actual exposure time.

        Before the second click of the camera button in the single-frame mode, the camera was still taking photos with continuous exposure.
        When the button was clicked, it began to display the exposure time,
        but the camera had been exposed for some time. When the actual exposure was finished, the image was displayed,
        so the display exposure time was less than the actual exposure time.
        In fact, the actual exposure is long enough.

        The second frame of EZCAP is the same, but it is not displayed immediately after the picture is got,
        which adds a delay time, so the display exposure time is equal to the actual exposure time.
