A new image-sensing method has been studied in order to reduce the size and cost of a consumer use HD camera with CCDs. The number of pixels has been minimized keeping the picture quality sufficient for home use by considering the suitability to the component video signal with a line-sequential chrominance signal expressed as Y:P_B:P_R = 4:1:0 which is commonly used in package media. As a result of frequency analysis and image simulation, the high resolution of more than 700 TV lines for both horizontal and vertical directions has been obtained using 3 CCDs with 0.43 Mpixels each. This has been attained by the newly developed color signal processing algorithm in which the way of pixel arrangement and signal processing has been optimized by using both 2-dimensional pixel arrangement method and sub-sampling image-sensing method.
