Abstract: The present technique relates to an imaging device and an imaging method, an electronic device, and a program, which are configured to improve an SN ratio by combining addition reading and thin-out reading by signal processing similar to signal processing using thin-out reading.First, as illustrated in the left side of the drawing, G pixel and B pixel, which are sub-colors, of the top row of regions Z1, Z2 are subjected to thin-out reading. Next, for W pixels of the main color arranged in a checkerboard pattern in the regions Z1, Z2, two pixels tied by a straight line in the drawing are subjected to addition reading at the same tone timing. For W pixels of the main color arranged in a checkerboard pattern in regions Z3, Z4, two pixels tied by a straight line in the drawing are also subjected to addition reading at the same tone timing. R and G pixels, which are sub-colors, of the lower stage of the regions Z3, Z4 are read.According to a relative relation between the main color and the sub-colors of the regions Z1 to Z4 as illustrated in the center of the drawing, Bayer arrangement is obtained as illustrated in the right side of the drawing.

Abstract: The present disclosure relates to a solid-state image-capturing element and electronic device capable of improving the linearity of illuminance values. The dynamic-range expander 118 expands dynamic range of a pixel value for each pixel based on the pixel value having different exposure times of a plurality of pixels. The integrator 119 integrates pixel values having the dynamic range expanded by the dynamic-range expander 118 and generates an illuminance value. The present disclosure is applicable to complementary metal-oxide semiconductor (CMOS) image sensor or the like used in, for example, an illuminometer.

Abstract: There is provided a signal processing device including a correction processing unit that acquires a pixel signal output from a sensor on which pixels are disposed in an array in which a spatial frequency of a color pixel which is a pixel acquiring a color component is lower than a spatial frequency of luminance pixels which are pixels acquiring luminance components, and then corrects the pixel signal output from a defective pixel out of the pixels that the sensor includes. During correction of a pixel signal of the color pixel, the correction processing unit performs correction referring to pixel signals of the luminance pixels having a spatial frequency higher than the spatial frequency of the color pixel.
