Abstract: In a driver circuit of a display device handling a digital image signal, there is provided a driver circuit with a structure in which the timing of holding the image signal in a latch circuit is not influenced by a delay of a sampling pulse. A pre-charge TFT (102) is turned ON in a return line period and an input terminal of a holding portion (101) is set as Hi (VDD).

Thus, holding of the digital image signal is performed. A sampling pulse width is wider than a pulse width of the two signals input from the outside, and the output periods of the two signals input from the outside are completely included in an output period of the sampling pulse.

In a single basic pattern a single pixel is assigned 1 serving as a number indicating an order followed to illuminate a dot in the dither matrix.

Abstract: An image device, such as a digital camera, detects specific repeating patterns of signal variations by processing columnar information from the device's two-dimensional sensor array used to generate images. In one embodiment, the columnar information is derived from calculating row averages for two image frames, with each row average being a computed average of the multiple signal intensities generated from some or all of the sensors within a particular row. After the columnar information is determined for each of the two frames, a difference signal is generated as a sequence of the differences between the row averages for the first frame and the row averages for the second frame. This row averaging and frame differencing removes a large percentage of the signal energy that is not a result of the artifact of interest, such as the flicker generated by illumination having intensity fluctuations at 100 Hz or at 120 Hz.
