A method and a wearable apparatus for diagnosing diseases are provided. The method is applied to the wearable apparatus with an image capturing unit and a display unit. In this method, a plurality of input images in a field of view of the wearable apparatus are captured by using the image capturing unit, in which each input image contain an array of pixels. The variations of the pixel strengths are analyzed in a space domain or a time domain. The pixel strengths within a specific frequency range are magnified and the magnified pixel strengths are added onto the original ones to generate an output image. The output image is overlapped with an instant image in the field of view of the wearable apparatus and displayed on the display unit.一種疾病檢測方法及穿戴式裝置，此方法適用於具有影像擷取單元及顯示單元的穿戴式裝置。此方法係利用影像擷取單元擷取穿戴式裝置視野內的多張輸入影像，這些輸入影像包括位置相對應的多個像素。然後，分析這些像素的像素強度在空間或時域上的變化，以放大所屬頻率帶位於特定頻率範圍內的像素強度，並將處理前後的像素強度疊加以產生輸出影像。最後，將輸出影像重疊於穿戴式裝置視野內的即時影像，並將輸出影像顯示於顯示單元。
