Abstract
In an image signal processing apparatus, line memories conventionally provided at a latter stage of the apparatus in order to convert a VGA image signal into a CIF image signal are eliminated. Image data of the VGA held in a unit of one line in plural line memoriesprovided in a digital signal processing circuit are weighted and added in a VLPF. A factor setting partof the VLPFchanges weighting factors according to a positional relation between a position of a generation object line of the CIF and a line of the VGA. The weighting factors are determined so that a characteristic of trapping ½ of a vertical sampling frequency fv is also obtained. The VLPFuses the weighting factors to trap fv/2, and changes the position of the vertical sampling point to a position of each line of the CIF image.
