A non-contact heartbeat rate measurement apparatus includes an image sensor and a computing module. The image sensor is configured to capture a plurality of facial images continuously. The computing module is coupled to the image sensor. The computing module is configured to select target areas from the facial images, obtain a heartbeat signal according to color variances of pixels in the target areas, and perform spectrum analysis on the heartbeat signal to obtain a heartbeat spectrum. The heartbeat spectrum includes heartbeat signal strength values under different frequencies. The computing module is configured to calculate a signal-noise ratio of the heartbeat spectrum, calculate a face-moving frequency according to the facial images, and select a frequency from the heartbeat spectrum as an output heartbeat frequency according to the signal-noise ratio and一種非接觸式心跳量測裝置,其包含影像感測器以及運算模組。影像感測器用以連續地擷取複數個臉部影像。運算模組與影像感測器耦接,運算模組用以自臉部影像中各自選擇目標區域,依據目標區域中各像素點的色彩差異量得到心跳訊號,對該心跳訊號進行頻譜分析並得到心跳頻譜,心跳頻譜包含在複數個頻率下的複數個心跳訊號強度值,運算模組計算心跳頻譜之訊號雜訊比,根據該些臉部影像計算臉部晃動頻率,根據訊號雜訊比與臉部晃動頻率以選擇出心跳頻譜的其中一頻率作為輸出心跳頻率。300‧‧‧非接觸式心跳量測裝置310‧‧‧影像感測器320‧‧‧運算模組330‧‧‧輸出介面340‧‧‧電源供應模組341‧‧‧電池模組342‧‧‧電源開關按鈕350‧‧‧固定模組
