Fourier ptychographic microscopy (FPM) is a new computational imaging technique that can provide gigapixel images with both a high-resolution and a wide field of view. However, the data-acquisition process is time-consuming, which is a critical issue. In this study, we analyze the FPM imaging system with the half number of captured images; i.e. if the size of the light-emitting diode (LED) array is 15 × 15, we use 15 × 8 LEDs to capture images. According to the image analysis of the…
