The detection/evaluation device (46) produces red, green and blue signals by superimposing the signals from two image sensors (22,23). The spectral characteristics of the two sensors are selected so that four light sensitive elements in a 2 x 2 matrix are colour complementary. The red, green and blue signals are produced by suitable superimposition of the signals from the four photosensitive elements of each sensor. The first and second sensors can have the same construction. Each has a complementary colour difference line sequence spectral characteristic. USE/ADVANTAGE - Imaging arrangement enables higher colour resolution to be achieved.
Imaging arrangement with two sensors - contains four colour complementary light sensitive elements in each sensor in 2 by 2 matrix.
