An image sensor capable of ensuring high sensitivity image and minimizing color distortion is provided. The image sensor includes a first filter unit, a second filter unit formed at a lower part of the first filter unit and a sensor unit formed at a lower part of the second filter unit. The first filter unit is configured to pass light corresponding to a visible light region, pass light corresponding to a first region of a longer wavelength than the light corresponding to the visible region and cut off light corresponding to a second region of a longer wavelength than the light corresponding to the first region. The second filter unit is configure to pass light having a predetermined wavelength in a wavelength range corresponding to the visible light region among the light passing through the first filter unit and pass light corresponding to the first region. The sensor unit is configured to detect the light passing through the second filter unit.

Image sensor and method using near infrared signal

A color filter array and image obtaining apparatus are provided. The color filter array includes at least one unit cell having a predetermined array of pixels, and the predetermined array including the color pixels and transparent pixels. Each 2&#xd7;2 array of pixels in the unit cell includes one transparent pixel and three color pixels and at least one transparent pixel is located in each row or in each column of the unit cell. The image obtaining apparatus generate an electrical image signal corresponding to sensed light that has passed through the color filter array.

Color filter array and image obtaining apparatus

A color filter array may include a plurality of pixels and control a pass wavelength band of the plurality of pixels using a dichroic filter that passes light of a specific wavelength range and blocks the rest of wavelengths. The pass wavelength band of the plurality of pixels may be adjusted according to a plurality of thicknesses of the dichroic filter. The dichroic filter may be formed by repeatedly forming a layer of titanium dioxide (TiO) and a layer of silicon dioxide (SiO).

Color filter array using dichroic filter

A method and apparatus may include aligning a reference image and an input image through ROI-based image alignment; detecting an ROI associated with an incompletely aligned region in the aligned image; and blending the aligned reference image and input image by using a plurality of weights which are attenuated according to a spatial distance from a boundary of the detected ROI. In addition, the method and apparatus may include aligning a reference image and an input image through image alignment based on an nregion of interest (ROI) which is detected at a previous stage; detecting another ROI associated with an incompletely aligned region in the aligned image; and blending the aligned image in the other ROI and an (n+1)blended image, which is input from a next stage, in a region outside the other ROI, and outputting the last blended image to the previous stage.

Method and apparatus for blending images

Provided are an image processing apparatus and method for restoring a high resolution of an image based on acquired image data using color information. The image processing apparatus selects at least one pixel from among pixels corresponding to narrow-band color information of image data, and estimates wide-band color information of the selected pixel.

Apparatus and method for processing images

A high dynamic range (HDR) image generating apparatus and method is provided. The HDR image generating apparatus may set an auto-exposure time, a long exposure time, a short exposure time, and a reference exposure time. The auto-exposure time may be set to be shorter than the long exposure time, the short exposure time may be set to be shorter than the auto-exposure time, and the reference exposure time may be set to fall within a range between the auto-exposure time and the short exposure time. The image generating apparatus may obtain a first image with the long exposure time and a second image with the reference exposure time, may correct motion in the first image and adjust a dynamic range of the second image, and then may composite the resultant first and second images to generate a high dynamic range image.

High dynamic range image generating apparatus and method

An apparatus and method for generating a high ISO image are provided. To this end, an image may be divided into a first image having a low frequency component and a second image having a high frequency component. A brightness of the first image may be changed, and details of the second image may be restored. The first image having the changed brightness and the second image having the restored details may be synthesized.

Apparatus and method for generating high ISO image

Disclosed is an apparatus and method for obtaining a motion adaptive high dynamic range image, in which a motion degree of a first image and a second taken using different exposure times is calculated. The motion calculation intensity is adjusted based on the calculated motion degree. The motion compensation intensity involves a global motion compensation and/or a location motion compensation. Images subjected to compensation are synthesized and output, so that an image having high dynamic range is obtained.

Apparatus and method for obtaining motion adaptive high dynamic range image

A technology of acquiring and processing light field data for images is provided. A light field data acquisition apparatus includes a modulator with an attenuation pattern to spatially modulate aD light field for an image, and a sensor to acquireD signals of the spatially modulatedD light field. By utilizing the attenuation pattern of the modulator, more spatial data may be acquired in a low angular frequency region than that acquired in a high angular frequency region.
