An RB rate calculator calculates an RB rate based on an R signal and a B signal. A starting point changing unit changes a starting point based on the RB rate. An offset calculating unit calculates an offset value to adjust for selection of a basic depth model type based on a bottom high frequency component evaluation value. An adding unit adds a signal from the starting point changing unit and an offset. Another adding unit adds an offset-added signal from the adding unit and a basic depth model-composed image signal supplied from a composing unit, and generates depth estimation data wherein a degree of superimposition of object information is changed according to a composition of a composed image of basic depth models selected to be composed.

摘要:
An active matrix type display panel is a hold type display panel which has a plurality of pixels arranged in a matrix form, and holds and displays an electrical signal pixel by pixel for a predetermined time. A frame rate conversion circuit converts a video signal having a first vertical frequency (60 Hz) into a video signal having a second vertical frequency (120 Hz) which is m/n-fold (wherein m is an integer of 2 or more, n is an integer of 1 or more, and conditions of m>n are satisfied) of the first vertical frequency. A time base emphasizing circuit subjects an output from the frame rate conversion circuit to time base emphasis. A drive circuit displays the video signal having the second vertical frequency in a display panel.

Noise components involved in a video signal are detected as follows: Extracted from the video signal are a first high-frequency component involved during each blanking interval, a second high-frequency component involved in a horizontal direction for each of pixels constituting each image carried by the video signal during each image-carrying period located between adjacent blanking intervals, a third high-frequency component involved in a vertical direction for each pixel by using the video signal and a 1-line delayed video signal generated by delaying the video signal by one line in the vertical direction, and a fourth high-frequency component involved in a time direction for each pixel by using the video signal and a 1-frame delayed video signal generated by delaying the video signal by one frame in the time direction. Statistical processing is performed to obtain an absolute value of each of levels of the second to fourth components for each pixel, and obtain the number of pixels in each image per level in absolute value from a level zero to at least a predetermined level in a range from the level zero to a maximum level in absolute value for each of the second to fourth components. A noise detecting signal is generated based on a level of the first component irrespective of a result of the statistical processing when the level of the first component is higher than a predetermined level. In contrast, when the level of the first component is equal to or lower than the predetermined level, obtained are three levels, as a first noise level, a second noise level and a third noise level, for the first, second and third components, respectively. Each of the three levels has the smallest number of pixels among levels other than the level zero each having a larger number of pixels than the level zero for the corresponding component. A noise detecting signal is generated based the lowest or the second lowest noise level among the first to third noise levels. The generated detecting signal is used for recursive noise reduction.

A Gaussian filter 2 having a first cutoff frequency extracts a low frequency component signal of a video signal. A subtracter 3 extracts a high frequency component signal by subtracting the low frequency component signal from the video signal. A low pass filter 5 having a second cutoff frequency higher than the first cutoff frequency extracts a lower high frequency component signal, which is a low-frequency-side signal of the high frequency component signal. A multiplier 6 generates a corrected component signal by multiplying the lower high frequency component signal by a predetermined gain G1. An adder 7 adds the corrected component signal to the video signal.
