Patent ID: 7142239

Claim:
An apparatus for processing the output data of an image sensor comprising: a line memory module for receiving and storing the output data of a single image sensor, having information on color signals sensed in each pixel; a delay module for receiving the output data of the image sensor and the output data of the line memory module, delaying the received output data for a predetermined time using a clock signal, and then outputting the received output data; a directional coefficient value selector for receiving the output data of the delay module, selecting values of a plurality of directional coefficients for defining the edge components of the Red (R), Green (G), and Blue (B) components of a pixel which is to be obtained, and outputting the selected values, wherein the plurality of directional coefficients include a first directional coefficient for indicating only which component the edge of the pixel has from among the horizontal component, the vertical component, and the diagonal component; a second directional coefficient for indicating only the degree of the horizontal edge component which has a predetermined width from the horizontal line, and includes the upper part component, the lower part component, and both the upper part and lower part components from the horizontal line; and a third directional coefficient for indicating only the degree of the vertical edge component which has a predetermined width from the vertical line, and includes the left part component, the right part component, and both the left and right part components from the vertical line; and an adaptive interpolator for receiving the output data of the delay module, and obtaining the R and B components of a pixel having the G component, the G and B components of a pixel having the R component, and the G and R components of a pixel having the B component, by performing interpolation using the received output data of the delay module in response to the output data of the directional coefficient value selector.
