摘要： An imaging device having five color filters. The five color filters include three color filters of a R (red) filter, a G (green) filter, and a B (blue) filter of a primary color system and two color filters of a Y (yellow) filter and a C (cyan) filter of a complementary system. The G filter has a checker shape G filter so that the space information of green is obtained four times larger than that of each of the other colors.

摘要： characteristic are improved. An imaging device having a hybrid RGBYC color filter using a primary color system RGB filter and a complementary color system YC filter is composed. Four G filters that directly relate to resolution and that is close to a luminance signal that human eyes sense are arrayed in a checker shape so that the number of the G filters is four times larger than the number of filters of each of the other colors. An array shown in FIG. 10A is composed of low resolution rows (G, R, G, and B) and high resolution rows (C, G, Y, and G) that are alternately arrayed in each line. When signals are read if exposure times are varied for individual lines, the signals that are read can easily have a wide dynamic range. An array shown in FIG. 10B has two Gs, a low sensitivity color, and a high sensitivity color in each line and each row. Thus, the luminance difference is small in the horizontal direction and the vertical direction. Thus, the reading method in the array shown in FIG. 10B is slightly complicated than that in the array shown in FIG. 10A. However, since the special interpolation characteristic of the array shown in FIG. 10B is advantageous, a smooth gradation can be easily represented.

摘要： A drive method for a solid-state imaging device having an oblique pixel pattern includes the steps of: adding, separately for an odd-numbered row and an even-numbered row, x pixels in the horizontal direction and y pixels in the vertical direction, the x pixels and the y pixels having the same color, in an area having adjacent n pixels in the horizontal direction and adjacent n pixels in the vertical direction, where n is an odd number of three or greater and n≧x≧y; and repeatedly adding the x pixels and the y pixels while shifting the n×n area by m pixels in the vertical or horizontal direction, where m is an odd number of three or greater. The n×n area of odd-numbered rows is displaced from that of even-numbered rows by m pixels in the oblique direction in the oblique pixel pattern.

摘要： An image pickup apparatus includes an image sensor including a color filter having pixels of different colors arranged in a predetermined order and a demosaic processor. The image sensor receives a subject image and outputs an image signal including color signals of the different colors. The demosaic processor generates color signals of the different colors for each of pixels of the image from the image signal. The demosaic processor includes a generation unit and a noise reduction unit. The generation unit performs computation using a target color signal representing a predetermined target color signal included in the image signal and a predetermined different color signal so as to generate a color-related signal that associates the target color signal with the predetermined different color signal for a pixel of the target color signal. The noise reduction unit performs a noise reduction process on the color-related signal generated by the generation unit.
