Summary:The utility model provides an optical sensing device. A breakdown bias voltage is provided to the light sensing diode. During a light sensing period, a count value is generated by counting the collapse times of the light sensing diode according to a light sensing signal generated by sensing ambient light when the light sensing diode receives the collapse bias voltage. Sampling the count value to generate a plurality of sampling values; and judging the light characteristic of the ambient light according to the sampling value. 本实用新型提供一种光学感测装置。提供崩溃偏压电压至光感测二极管。于光感测期间依据光感测二极管在接收该崩溃偏压电压时感测环境光而产生的光感测信号计数光感测二极管的崩溃次数而产生计数值。取样计数值而产生多个取样值。依据取样值判断环境光的光特性。
