IMAGING DEVICE AND IMAGING ELEMENT

Title:

IMAGING DEVICE AND IMAGING ELEMENT

Document Type and Number:

WIPO Patent Application WO/2006/080220

Kind Code:

A1

Abstract:

To improve color reproducibility and noise characteristics. An imaging element provided with hybrid RGBYC color filters is constituted by using primary color-based RGB filters and complementary color-based YC filters. Four times as many G filters, close to the brightness signal of a human eye directly related to resolution, as the numbers of other color filters are disposed in a checkered form. The arrangement shown in Fig. 10A provides, checked column by column, low-sensitivity rows (G, R, G, B) and high-sensitivity rows (C, G, Y, G) that are arranged alternately. When they are read with exposure time changed column by column, a wide-dynamic-range reading is easily possible. The arrangement shown in Fig. 10B provides two Gs that are respectively included in columns and rows, and the remaining two colors that are combinations of high-sensitivity and low-sensitivity ones; providing an arrangement in which the difference in luminance between horizontal and vertical directions is very small. Therefore, when compared with the arrangement in Fig. 10A, although complicated in reading method, the latter can easily realize a smooth gradation representation due to advantage in spatial interpolating characteristics.
