Abstract
An image processing apparatus and control method are provided. The image preprocess apparatus includes an image receiver which receives an analog broadcasting signal; an image processor which converts the analog broadcasting signal into a digital broadcasting signal; and a filtering unit which selectively performs a low pass filtering on the analog broadcasting signal to filter a frequency higher than a preset frequency and transmits the selectively-filtered analog broadcasting signal to the image processor corresponding to a reception of the analog broadcasting signal by air.
Claims14
An image processing apparatus comprising:
- an image receiver which receives an analog broadcasting signal;
- an image processor which converts the analog broadcasting signal into a digital broadcasting signal;
- and
- a filtering unit which selectively performs a low pass filtering on the analog broadcasting signal to filter a frequency higher than a preset frequency according to determination of reception mode of the analog broadcasting signal by the image receiver,
- wherein the filtering unit performs the low pass filtering and transmits the filtered analog broadcasting signal to the image processor if the analog broadcasting signal is received by air.
A control method of an image processing apparatus comprising:
- receiving an analog broadcasting signal;
- selectively performing low pass filtering on the analog broadcasting signal to filter a frequency higher than a preset frequency according to determination of reception mode of the analog broadcasting signal by the image processing apparatus;
- and
- converting the selectively-filtered analog broadcasting signal into a digital broadcasting signal,
- wherein the selectively performing is performed if the analog broadcasting signal is received by air.
A broadcasting signal receiver comprising:
- an image receiver that includes a cable input and a wireless input, and is configured to receive an analog broadcasting signal over a cable by the cable input or over air by the wireless input;
- an image processor which converts the received analog broadcasting signal into a digital broadcasting signal;
- and
- a filtering unit which selectively performs a low pass filtering on the analog broadcasting signal to filter a frequency higher than a preset frequency according to determination of reception mode of the analog broadcasting signal by the image receiver, wherein, if the analog broadcast signal is received over the air by the wireless input, the filtering unit performs the low pass filtering on the analog broadcast signal, and if the analog broadcast signal is received over cable by the cable input, the filtering unit does not perform the low pass filtering.
