Provided are a pixel processing apparatus, and an image signal processing apparatus and an image processing system each including the same. The pixel processing apparatus includes a bad pixel processing unit configured to determine whether a target pixel is a bad pixel based on pixel data of an image sensor, output a bad pixel detection signal according to a result of determining whether the target pixel is a bad pixel, compensate for a pixel value of the target pixel based on the pixel data, and output the compensated pixel value; and a noise removal unit configured to remove noise from the pixel value of the target pixel, based on the bad pixel detection signal, the pixel value, the compensated pixel value, and weight information.

Pixel processing apparatus of processing bad pixel and removing noise, and image signal processing apparatus and image processing system each including the same

An image sensor chip includes a first wafer and a second wafer. The first wafer includes an image sensor having a plurality of sub-pixels, each of which is configured to detect at least one photon and output a sub-pixel signal according to a result of the detection. The image processor is configured to process sub-pixel signals for each sub-pixel and generate image data. The first wafer and the second wafer are formed in a wafer stack structure.

Image sensor chips

An image sensor includes a pixel array and a row driver block. The pixel array includes a plurality of subpixel groups, each including a plurality of subpixels. Each of the plurality of subpixels is configured to generate a subpixel signal corresponding to photocharge accumulated in response to a photon. The row driver block is configured to generate a first control signal to control the subpixels included in each of the plurality of subpixel groups to accumulate the photocharge in parallel from a first time point to a second time point.

Image sensor and image processing system including subpixels having a transfer circuit, comparator and counter for outputting the count value as the subpixel signal

An image sensor, an image processing apparatus including the same and an interpolation method of the image processing apparatus are provided. The image sensor includes a plurality of pixels that include a low-luminance pixel including a first photoelectric conversion device that accumulates a charge less than a predetermined reference value and a high-luminance pixel including a second photoelectric conversion device that accumulates a charge more than the predetermined reference value. Interpolation is carried out giving more weight to the low-luminance pixel at low luminance and giving more weight to the high-luminance pixel at high luminance, so that a higher SNR is obtained.

Image processing apparatus and interpolation method operable to calculate a luminance and interpolate color by adjusting a signal output from at least one low-luminance pixel and at least one high-luminance pixel
