The shape of a moving object is reconstructed from a shot image under relatively-strong ambient light or an embedded image is demodulated from a video image in which an image that may not be visually recognized is embedded to display the image. The image processing method of the present invention includes irradiating flashing light to the surface of the object based on a spreading signal obtained by spread spectrum modulation, receiving reflected light from the surface of the object to output the signal including the image information, a filtering for eliminating noise including a low-frequency component from the signal including the image information, inverse-spreading the signal after the filtering to demodulate the signal, and outputting, based on a signal obtained by the demodulation, an image reflecting the state of the surface of the object.

A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.
