Various embodiments include an apparatus including a phase mask and circuitry. The phase mask is configured and arranged with optics in an optical path to modify a shape of light, passed from an object. The shape modification characterizes the light as having two lobes with a lateral distance that changes along a line, having a first orientation, as a function of an axial proximity of the object to a focal plane, and with the line having a different orientation depending on whether the object is above or below the focal plane. The circuitry is configured and arranged to generate a three-dimensional image from light detected at the image plane, by using the modified shape to provide depth-based characteristics of the object.

According to one embodiment, an electronic device includes one or more processors. The one or more processors obtain an image captured by a camera with a filter having a first area transmitting light of a first wavelength range and a second area transmitting light of a second wavelength range. The image includes a first color-component image based on the light of the first wavelength range and a second color-component image based on the light of the second wavelength range. The one or more processors notify a user of an effective area for calculation of depth information based on a bias of color information in the first color-component image and the second color-component image.

An imaging device that includes a first color filter, a second color filer and an image sensor. The first color filter includes a first plurality of color filter regions that transmit a color of a first set of colors. The second color filter includes that transmit a color of a second set of colors. The second set of colors is different from the first set of colors. The image sensor detects light that passes through both the first color filter and the second color filter and generates an image signal.
