Attention:(1)The data is recommended to be sampled at the rising edge of Clock;

(2)   Field synchronization and line synchronization are both highly effective;

(3)   Image data format is YUV422,Data low value is Y,high value is U/V;

(4)   The temperature data unit is(Kelvin(K)*10),actual temperature is read-out value /10-273.15(℃)。
