| 发明名称 | Image capturing apparatus | ||
| 摘要 | The image capturing apparatus includes an optical low-pass filter configured to separate one incident ray into multiple rays to form multiple point images, and an image sensor configured to photoelectrically convert the multiple point images. The optical low-pass filter satisfies a condition of 0.4<2×σ/P<0.9. P represents a pixel pitch of the image sensor, and σ represents a standard deviation of a distribution of the multiple point images. | ||

| 主权项 | 1. An image capturing apparatus comprising: an optical low-pass filter configured to separate one incident ray into multiple rays to form multiple point images; and an image sensor configured to photoelectrically convert the multiple point images, wherein the optical low-pass filter satisfies the following condition: 0.4<2×σ/P<0.9where P represents a pixel pitch of the image sensor, and σ represents a standard deviation of a distribution of the multiple point images, and wherein the optical low-pass filter is configured to separate the one incident ray, when one of the separation directions thereof is defined as 0°, in each of four directions of 0°, 45°±10°, 90°±10°, and 135°±10°. | ||
