Hello,

Z1 doesn't support Burst shot( continuouse capture). and according to the description, camera_capture_cb() is called per each image.

int camera_start_continuous_capture  ( camera_h  camera, 
   int  count, 
   int  interval, 
   camera_capturing_cb  capturing_cb, 
   camera_capture_completed_cb  completed_cb, 
   void *  user_data 
 )

Remarks:

         If this is not supported zero shutter lag occurs. The capture resolution could be changed to the preview resolution.
 This function causes the transition of the camera state from CAMERA_STATE_CAPTURING to CAMERA_STATE_CAPTURED automatically
 and the corresponding callback function camera_capturing_cb() and camera_capture_completed_cb() will be invoked
 Each Captured image will be delivered through camera_capturing_cb().
 The camera_capture_completed_cb() callback notifies about the completion of an entire capture.
 The camera's preview should be restarted by calling camera_start_preview().

Hope this will help you.

  Hi, 

Thanks for your info.

I have tested the  below APIs on Z1, all return false, seems Z1 not support continous capture. But I have one more question, what the min- interval value of the normal capture, I set an 200 millisecond in a for loop, but the interval always lager than it.

camera_is_supported_zero_shutter_lag(cam_data.g_camera);
camera_is_supported_continuous_capture(cam_data.g_camera);
 

Hi, 

I used normal capture, but in a for loop I set a delay. After tested, I found the camera need to take about 0.7 seconds to capture one image. Is there anyone know the the exactly min interval of the Z1 in normal capture?

my code is listed below:

for (int count = 0; count < 20; count++) {
            usleep(200000); //0.2second delay, but accually result is take one image need take 0.7 seconds
            camera_start_preview(cam_data.g_camera);
            error_code = camera_get_state(cam_data.g_camera, &state);
            dlog_print(DLOG_ERROR, LOG_TAG,
                    "camera_set_preview_cb  camera_get_state = %d", state);
            error_code = camera_start_capture(cam_data.g_camera,
                    _camera_capturing_cb, _camera_completed_cb, NULL);

            error_code = camera_get_state(cam_data.g_camera, &state);
            dlog_print(DLOG_ERROR, LOG_TAG,
                    "camera_start_capture count= %d camera_get_state = %d",
                    count, state);
        }

Hello, 

Yes, you are right, I have test in the code, the camera performance is impacted by the CPU&memory, and it's hard to got an exactly value. But what I want to do is try to find the minmum interval of Z1 in normal capture mode, can you share more details about the burst mode?
