摘要： An image signal processing device has an LSI including a ROM access control circuit for holding data for controlling an operation of a video signal processing unit, and a flush ROM that is disposed outside the LSI, holds control data to be transmitted to the ROM access control circuit, and allows data read to be controlled by the ROM access control circuit. The data transferred between the flush ROM and the ROM access control circuit has data that must be updated every field and data that does not need to be updated every field. The data is transferred in a vertical blanking time period of the video output data. This configuration allows certain transfer of required data using the vertical blanking time period.

摘要： A vertical interpolation circuit interpolates an interpolated pixel with pixels located on upper and lower vertical positions, and outputs a vertical interpolated value. An oblique averaging part averages pixels obliquely located with respect to the interpolated pixel on the basis of an oblique edge angle signal, and outputs the result of calculation as an oblique average. An oblique difference absolute value operation part calculates the absolute value of the difference between the values of the pixels obliquely located with respect to the interpolated pixel on the basis of the oblique edge angle signal, and outputs the result of calculation as an oblique difference absolute value. A mixing part outputs the vertical interpolated value, the oblique average or a mixed value thereof as an interpolated pixel value on the basis of the oblique difference absolute value.

摘要： PROBLEM TO BE SOLVED: To provide an image display device which is implemented suitably for a spontaneous emission display panel such as a plasma display panel and an organic EL panel and which is constituted in a way that another video signal is superposed on an input video signal, whereas gray shades display is performed with emission frequency in one field of each pixel, and an amount of power consumption of a panel is reduced by predicting the amount of power consumption of the panel per unit area and switching emission systems from its prediction value, the image display device in which time required for a prediction calculation and a memory for delaying a video signal are reduced. SOLUTION: A first APL calculation circuit 33 predicts the amount of power consumption not from output of a data superposition circuit 37 but from the inputted video signal. Thus, resizing and the prediction calculation are performed within delay time by a delay circuit 31 and the memory is reduced. In addition, an error to be generated by the superposed data is compensated by multiplying the number of emitted pulses by mode ratio in a subfield pulse generation circuit 41 using a second APL calculation circuit 44 and a second controller 45.
