Imaging device, imaging method, electronic device, and program

摘要

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. The present technique can be applied to an imaging device.

主权项

1. An imaging device, comprising:
pixels arranged in a two dimensional matrix; a main color filter of a predetermined color component of a luminance signal for the pixels; additional color filters of other color components than the predetermined color of the luminance signal for the pixels; and signal processing circuitry configured to, for the pixels in a subgroup of the matrix, thin out signals of the pixels to which the additional color filters are provided in a first half of the subgroup to output a first thinned out result, then add signals together of the pixels to which the main color filter is provided to output an addition result, and then thin out signals of the pixels to which the additional color filters are provided in a second half of the subgroup to output a second thinned out result.
