Patent ID: 8035740

Claim:
An image processing apparatus for deinterlacing and vertical scaling a plurality of initial scan lines, the image processing apparatus comprising: a control unit for receiving at least one parameter; an accessor coupled to the control unit for accessing at least one of the initial scan lines according to the control of the control unit; a deinterlacer coupled to the control unit and the accessor for outputting at least one corresponding scan line according to the accessed initial scan lines; a storage unit coupled to the deinterlacer for storing at least one of the corresponding scan lines outputted from the deinterlacer; and a vertical scaler coupled to the control unit, the deinterlacer and the storage unit for performing a vertical scaling according to the at least one corresponding scan line outputted from the deinterlacer and at least one of the corresponding scan lines stored in the storage unit thereby outputting at least one output scan line; wherein the control unit determines whether to store the corresponding scan line into the storage unit according to the parameter.
