Member Function Documentation

void otCamera.dataAlignment (  otImage &  image  )

This function is used only with the TIZIANO camera. Unfortunately the PYTHON1300 sensor, used on the TIZIANO camera, produces in output a sequence of digitized pixels not with the expected order. See the chapter DATA OUTPUT FORMAT on the data sheet. This function remedies this problem. This feature has a very heavy impact on processing times, for critical cases use on a higher performing remote system. By setting the processor to an operating frequency of 525MHz with a peripheral frequency of 131MHz, we obtain a capture time at full resolution (1280x1024) of 22.5 ms, while it takes 136 ms to correct it. Parameters: image  Image class pointer

void otCamera.grab (  otImage &  img, int  timerId = -1, bool  adjust = true )

Grab an image(s) according to img class set Parameters: img  Image class pointer timerId  Timer identifier, used to evaluate FPS adjust  Adjust data on Tiziano camera module

bool otCamera.grabIsDone (  otImage &  img, int  timerId = -1 )

Return true if the starting image grab is done. Parameters: img  Image class pointer timerId  Timer identifier, used to evaluate FPS

void otCamera.grabStart (  otImage &  img, int  timerId = -1 )

Begins capturing an image but does not wait for it to complete. Parameters: img  Image class pointer timerId  Timer identifier, used to evaluate FPS

void otCamera.init (  U8  camId  )

Init the library Parameters: camId  Camera identifier

void otCamera.standby (  bool  ena  )

Set camera power down or restart it Parameters: ena  True to enable power down
