Abstract: A high resolution image producing method includes the following steps. Firstly, an object is continuously shot to produce plural shot images. Then, plural original images are selected from the plural shot images. Then, each of the original images is segmented into plural blocks, and the motion vector of each block of each original image is calculated. Then, a first original image is scaled-up to acquire a first basis image, and a second basis image is acquired by copying the first basis image. A phase error is calculated according to the first basis image, and an interpolating operation is performed on the second basis image to obtain a high resolution image.

Abstract: The present invention pertains to a frequency-lock filtering receiver and the method for the same. The receiver enters a tuning mode before receiving signals. A frequency synthesizer then generates the radio frequency (RF) to be received and adjusts the central frequency of a tunable filter through feedback control so as to lock in the RF to be received. Afterwards, the receiver enters a receiving mode to receive RF signals using an antenna and uses the central frequency of the tunable filter locked in the tuning mode to filter the RF signals and to receive signals.
