摘要： The liquid crystal display device inputs a signal, corrected by a correction circuit provided with a sigmoid inverse function generator, to a source driver. A sigmoid function which is an S-shaped function is used to approximate an input/output characteristic (applied voltage-transmittance curve) of a liquid crystal panel. The sigmoid inverse function generator converts an input signal by using an inverse function of the sigmoid function obtained by performing the approximation. A γ conversion circuit provided on the correction circuit and the sigmoid inverse function generator realize the desired γ characteristic regardless of a characteristic of the liquid crystal panel. Further, since the inverse function of the sigmoid function which is an S-shaped function is used, it is possible to provide a display device which corrects the input/output characteristic of the display panel by performing the approximation in accordance with not plural functions but a single function (without dividing the characteristic into sections).

摘要： In an image displaying device provided with a frame rate conversion (FRC) portion, the image quality deterioration in a moving image likely to include a plurality of the same consecutive images due to a FRC processing is prevented. The FRC portion (100) of the image displaying device includes a motion vector detecting portion (101) that detects motion vector information from an input image signal, an interpolation frame generating portion (106) that generates interpolation frames based on the motion vector information obtained by the motion vector detecting portion (101) and a same image detecting portion (105) that detects a case where the same images continue in the input image signal. In the case where the image of the (n−1)-th frame in the input image signal is substantially the same as the image of the n-th frame, interpolation image generating processing with the motion compensation processing made ineffective is performed between n-th frame and (n+1)-th frame to prevent that the interpolation image including a lot of errors is output.

摘要： In an image displaying apparatus including a motion compensated rate converting (FRC) portion, deterioration of image quality is prevented in an image having a high-speed region and a low-speed region mixed. The FRC portion includes a motion vector detecting portion 11e and an interpolation frame generating portion 12b. The motion vector detecting portion 11e includes a first region detecting means 112e1 that detects a first region (high-speed region) including a motion amount equal to or greater than a first predetermined amount from an input image signal, a second region detecting means 112e2 that detects a second region (low-speed region) including a motion amount equal to or less than a second predetermined amount from the input image signal, and a third region detecting means 113e that detects a still region from an inter-frame difference of the input image signal. The interpolation frame generating portion 12b executes a motion compensated interpolation process using motion vectors for the still region in the first region (background) and executes a zero-vector interpolation process for the still region in the second region (foreground).

摘要： The quality of moving picture image with a large moving amount is prevented from deterioration due to moving compensation type frame rate conversion (FRC) processing. The image display device is comprised of an FRC unit (10) that interpolates an image signal subjected to moving compensation processing between frames so as to convert the number of frames of the input image signal, a moving amount judging unit (14) that judges whether a moving amount of the input image signal between the frames is larger than a predetermined value or not, and a control unit (15). The FRC unit (10) is provided with a moving vector detecting unit (11e) that detects a moving vector between the frames of the input image signal, an interpolation vector evaluating unit (11f) that allocates an interpolation vector between the frames on the basis of the moving vector information and an interpolation frame generating unit (12d) that generates an interpolation frame from the interpolation vector. In the case where the moving amount between the frames of the input image signal is larger than the predetermined value, the control unit (15) sets the moving vector detected by the moving vector detecting unit (11e) to be zero-vector, and it invalidates the moving compensation processing of the FRC unit (10).
