A display apparatus is disclosed. The display apparatus includes a converter configured to convert image pixel values corresponding to three primary colors (e.g., red, green and blue) into tri-stimulus values, a first maximum value unit configured to output a maximum value of the image pixel values as a first maximum value, a second maximum value unit configured to output a maximum value of the tri-stimulus values as a second maximum value, a gain adjuster configured to output a gain adjustment corresponding to the first maximum value and the second maximum value, and a gain applier configured to output a color adjustment value corresponding to the tri-stimulus values and the gain adjustment.

Apparatus and method for adjusting color of display apparatus

A touch sensor is disclosed. The touch sensor includes a touch panel including sensing nodes arranged in a matrix form and sensing lines connected to the sensing nodes, a touch sensing unit for providing driving signals for driving the sensing nodes, and a selector including a plurality of multiplexers for selectively providing the driving signals provided from the touch sensing unit to the sensing lines of the touch panels, wherein each of the multiplexers is selectively connected to two or more corresponding sensing nodes among the sensing nodes, and the two or more sensing nodes of the touch panel, selectively connected to each of the multiplexers, are positioned at different columns and rows.

Touch sensor, display apparatus including the same, and method of sensing touch panel

An image sensor includes a pixel array unit including an active pixel area including active pixels, a first dark area including first dark pixels, and a second dark area including second dark pixels, an offset extractor configured to extract a final dark offset value, and a corrector configured to correct pixel data values of the active pixels based on the final dark offset value. The offset extractor extracts a per-column dark offset value, a global dark offset value, a per-row average, and a per-row noise value, selects one of the extracted per-column dark offset value and global dark offset value, and extracts the final dark offset value from the per-row noise value and either the per-column dark offset value or the global dark offset value.

Image sensor and method of sensing image

Disclosed is an image sensor. The disclosed image sensor includes a pixel array including a plurality of unit pixels arranged in a matrix form having rows and columns, a binning sampling unit configured to output a binning sampling signal according to an average of signals from two or more unit pixels selected from among the unit pixels of each of the columns, and an analog-to-digital converter configured to convert the binning sampling signal to a digital signal. The selected unit pixels have different exposure times.

Image sensor

An image sensor includes a pixel unit configured to output a bayer pattern by converting an optical signal of a subject into an electrical signal; and a vertical interpolation unit configured to generate a vertical binning image by adding or averaging values of vertical pixels of the bayer pattern based on weight information set for each row region of the bayer pattern. Further, the image sensor includes a horizontal interpolation unit configured to generate a horizontal binning image by adding or averaging values of horizontal pixels of the bayer pattern based on weight information set for each column region of the bayer pattern; and an image composition unit configured to generate a weight-based binning image by composing the vertical and horizontal binning images.

Image sensor and method of generating binning image using the same

Disclosed herein is a method of driving a touch panel having driving lines, sensing lines, and node capacitors between neighboring driving lines and sensing lines. The method includes pairing two neighboring driving lines, setting the pairs such that each of the pairs is driven using driving signals having an opposite phase, shuffling positions of the pairs so that at least one set of neighboring pairs includes different driving lines, classifying or combining at least two shuffled pairs into one group, generating Hadamard codes based on the pairs in each group, and simultaneously driving the driving lines in each of the generated Hadamard codes.
