An object of the present invention is to detect a failure of a camera input in a system including a camera or a video transmission path (camera input). An image processor includes a hash derivation circuit having a computing unit that calculates hash values on an input screen and a storage circuit that stores the hash values. The image processor compares the hash values between multiple frames so as to decide whether the screens have changed or stopped. A failure is detected when the screens are stopped.

A method for controlling a digital display device and a digital display system implementing the method are provided in which a required luminance level for a pixel is controlled according to a store provided for each pixel, the contents of which indicate the number of discrete display update periods during an image refresh period for the pixel for which the pixel is to be illuminated to achieve the required luminance level, the content being read at each update period and the content determining whether the pixel is to be illuminated for that update period, the content being updated at each update period for which the pixel is illuminated to indicate that the number of update cycles for which the pixel is to be illuminated is thereby reduced by one and wherein the content of the store may be updated at any update cycle in response to changes in required pixel luminance level indicated by received image data.

A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period.

A method for generating a drive signal for driving a light emitting element of a display. The method includes: dividing the M bits into MN1+1 data ranges, each including N1 consecutive bits of the M bits; determining N2 bits for uniquely identifying the MN1+1 data ranges; generating a coded signal of N1+N2 bits for representing the M bits of the input signal; based on the coded signal, generating the drive signal comprising a sequence of N1 bits, each bit of said sequence of N1 bits controlling a current through the light emitting element or a voltage across the light emitting element, during a time interval, one bit at a time.

A display device and modulation scheme for applying image data to an imager is disclosed. The display may use a modulation scheme wherein spacing of row write actions on the rows creates gray scale modulation, wherein one row spacing between sequential row write actions is at a first distance while another row spacing between sequential row write actions is at a distance greater than said first distance. The modulation scheme may create a series of write pointers that create a corresponding series of write planes. In some embodiments, modulation efficiency is increased allowing the use of lower frequency imaging circuits to achieve the same display image.
