Imaging apparatus, imaging method, and program
View Patent ↗There is provided an imaging apparatus including a correction section configured to amplify an addition pixel value, which is a value obtained by adding results of photoelectric conversion on a plurality of pixels, according to an amplification factor set based on a number of defective pixels included in the plurality of pixels, and output the amplified addition pixel value as a corrected addition pixel value.
1. An imaging method comprising:
amplifying an addition pixel value, which is a value obtained by adding results of photoelectric conversion on a plurality of pixels, according to an amplification factor set based on a number of defective pixels included in the plurality of pixels; and
outputting the amplified addition pixel value as a corrected addition pixel value.
2. The imaging method according to claim 1 , further comprising:
setting the amplification factor by designating a number of black spot pixels, which does not increase the addition pixel value regardless of an amount of received light, as the number of defective pixels.
3. The imaging method according to claim 2 , further comprising:
preventing a result of the photoelectric conversion on a white spot pixel, which increases the addition pixel value regardless of an amount of received light, from being added to the addition pixel value, and calculating the number of defective pixels by regarding the white spot pixel as a black spot pixel.
4. The imaging method according to claim 3 , further comprising:
preventing the result of the photoelectric conversion on the white spot pixel from being added to the addition pixel value in each pixel by an image sensor which is provided with a fuse, and
wherein the fuse of the white spot pixel is disconnected.
5. The imaging method according to claim 3 , further comprising:
preventing the result of the photoelectric conversion on the white spot pixel from being added to the addition pixel value in each pixel by an image sensor which is provided with a logic gate, and wherein the logic gate of the white spot pixel is in a non-conductive state.
6. The imaging method according to claim 1 , further comprising:
generating a pixel value of a defective pixel based on a pixel value of a pixel adjacent to the defective pixel and outputting the generated pixel value as a corrected pixel value.
7. The imaging method according to claim 1 , wherein the amplification factor is increased according to an increase in a proportion of the number of defective pixels to the plurality of pixels.
8. The imaging method according to claim 7 , further comprising:
calculating a normal pixel count indicating a number of normal pixels among the plurality of pixels, based on the number of the plurality of pixels and the number of defective pixels, and setting a value based on a proportion of the calculated normal pixel count to the number of the plurality of pixels as the amplification factor.
