An image sensor includes; a pixel array disposed in a Bayer pattern and including pixels which respectively generate electrical charge according to received light incident, and an analog logic configured to convert an analog signal output from at least one pixel among the pixels into a first digital code using analog-to-digital conversion, and convert the first digital code into a second digital code by adjusting low-order bits of the first digital code in response to a control signal.

Image sensor, image sensing device including same, and operating method

An image processing device comprises an image sensor including unit groups comprising a reference group and a conversion group each including pixels and color filters, and is configured to generate image data using the pixels, and an image signal processor which is configured to calculate a hash of the image data, and to select a filter corresponding to the hash to perform filtering, wherein the image signal processor includes a pixel index converter which is configured to convert indexes of the pixels based on a positional relationship between the pixels, a pixel property converter which is configured to convert the properties of the pixels and to convert the hash before conversion, and a filter coefficient converter which is configured to convert filter coefficients of the pixels based on the respective converted pixel index and the respective converted pixel property.

Image processing device and image processing method using the same

An image sensor having improved image quality is provided. The image sensor includes a first array of pixels, a second array of pixels, and a binning module. The first array of pixels has a color pattern formed in an n&#xd7;m array and includes at least first-color pixels, second-color pixels, and third color-pixels. The second array of pixels is adjacent to the first array of pixels and has the same color pattern formed in an n&#xd7;m array as the first array of pixels, to include at least first-color pixels, second-color pixels, and third color-pixels. The binning module is configured to, for a sensed image: perform binning on the first-color pixels of the first array, the first-color pixels of the second array, the second-color pixels of the first array, and the third-color pixels of the second array, and not perform binning on the third-color pixels of the first array, and not perform binning on the second-color pixels of the second array.

Image sensor and method for sensing image

An RGBW image sensor, a binning method in an image sensor, and a computer readable medium for performing the method are provided, and the binning method in an image sensor includes selecting one or more binning target pixels for each of a red pixel, a green pixel, a blue pixel, and a white pixel, constituting a pixel array of an RGBW image sensor with a uniform array pattern, generating binning pixel data for each of the red pixel, the green pixel, the blue pixel, and the white pixel, based on pieces of pixel data corresponding to the binning target pixel, and rearranging pixels, represented by the binning pixel data, to be equal to the entirety or a portion of the uniform array pattern and to be equally spaced apart from each other.

RGBW image sensor, binning method in image sensor and computer readable medium for performing the method

An image processing device includes a first wide dynamic range (WDR) image generation block, a control signal generator, and a second WDR image generation block. The first WDR image generation block processes a long-exposure image signal to generate a first image signal, processes a short-exposure image signal using a second weight value to generates a second image signal, and to synthesize the first image signal and the second image signal to generate a first WDR image signal. The control signal generator calculates a difference between the second weight value and a reference weight value and generates control signals according to a result of the calculation. The second WDR image generation block adjusts a noise level of the first WDR image signal using the control signals and generates a second WDR image signal according to a result of the adjustment.
