Patent ID: 8553050

Claim:
An apparatus for processing a video signal, comprising: a first resizing unit which resizes first-format image data and outputs first-format image data with a first size which corresponds to a display size for TV monitor; a generating unit which generates a composite video signal with the first size from the first-format image data with the first size; a format converting unit which converts the first-format image data with the first size into second-format image data with the first size, wherein the second-format image data is RGB data; a point sequential converting unit which converts the second-format image data with the first size converted by said format converting unit into point sequenced data with the first size; a second resizing unit which resizes the point sequenced data with the first size converted by said point sequential converting unit and outputs the point sequenced data with a second size which corresponds to a display size for a display panel of the apparatus; a line memory which stores the resized point sequenced data with the second size output by said second resizing unit; and an output control unit which controls to continuously read out the point sequenced data with the second size from said line memory, wherein said point sequential converting unit outputs data of two consecutive points having the same color from the second-format image data which is RGB data, and said second resizing unit outputs resized data from the data of the two consecutive points by a linear interpolation calculation.
