Abstract
Provided are methods and apparatuses generating a color image and a depth image by using a first filter that transmits light in multiple wavelength bands and a second filter that transmits light in a particular wavelength band that is included in multiple wavelength bands.
Claims33
An image generation apparatus generating an image by using light reflected from a subject, the image generation apparatus comprising:
- a first filter to transmit light of multiple wavelength bands from the light reflected from the subject;
- a second filter to selectively transmit light in a select wavelength band from the light of the multiple wavelength bands, according to a control signal;
- a detection unit to detect a first image by photo-electrically converting the light of the multiple wavelength bands and detect a second image by photo-electrically converting the light in the select wavelength band;
- and
- an image processing unit to generate a color image and a depth image by using a difference image, obtained by subtracting the second image from the first image, and the second image.

A method of generating an image by using light reflected from a subject, the method comprising:
- performing first filtering to transmit light in multiple wavelength bands that include the light reflected from the subject;
- detecting a first image by photo-electrically converting the light in the multiple wavelength bands passed by the first filtering;
- performing second filtering to transmit light in a select wavelength band from the light in the multiple wavelength bands;
- detecting a second image by photo-electrically converting the light in the select wavelength band passed by the second filtering;
- and
- generating a color image and a depth image based on a difference image, obtained by subtracting the second image from the first image, and the second image.
