摘要： The present invention provides a noise quantity measuring apparatus adaptable to a video input signal subjected to automatic gain control. A luminance determination circuit compares luminance levels of respective pixels constituting a video input signal VIN and a predetermined threshold value for every arbitrary area Ai. If even one of the luminance levels exceeds the threshold value, then the luminance determination circuit outputs a detection signal DET to the corresponding area Ai. Sums SUMi of luminance level differences developed every plural arbitrary areas Ai, which are outputted from an integration circuit, are supplied to a selection circuit, where they are compared with an output signal OUT. Thereafter, each smaller value is supplied to a register. The register holds the output of the selection circuit in accordance with a latch signal LAT supplied from a pulse generator. On the other hand, when the detection signal DET is outputted, the latch signal LAT outputted from the pulse generator is stopped. Thus, the sum of the luminance level differences with respect to each area having pixels whose luminance levels exceed the threshold value, is ignored and eliminated from an output signal OUT indicative of the quantity of noise.

摘要： A video signal processor recursively removes noise from luminance signal data, storing only one frame of the luminance signal data, and detects luminance motion by comparing the current and stored luminance data to decide whether to output the current color difference data, the average of the current color difference data and the color difference data one frame before, or the average of the current color difference data and the color difference data two frames before. The decision may also involve detection of color noise by comparison of the color difference data with the data one frame before, or detection of color motion by comparison of the color difference data with data two or four frames before. Color data stored for color noise detection may also be used for recursive color noise removal. Accurate noise reduction is possible with a comparatively small amount of memory.

摘要： A noise reduction circuit and method effectively reduce noise with a simple structure regardless of the partial content of an image while suppressing an increase in the capacity of the image memory used and process delays. The present invention forms noise-reduced data by utilizing a correlation between from the difference between a pixel subjected to noise reduction and data of a pixel that is shifted by a predetermined amount in a time direction and/or spatial direction, and forms a difference cause discriminating signal indicating whether the difference is due to a valid change of the image. The noise-reduced data and the difference cause discriminating signal are formed for a plurality of different correlations. Final noise-reduced video data are obtained by selecting a method for determining the final noise-reduced video data based on the difference cause discriminating signals, and accordingly selecting/combining the plurality of noise-reduced data.

摘要： Disclosed is a driving force control device that includes a determination section (12), a driving force command value calculation section (13), and a command value output section (14). The determination section (12) determines whether each of a plurality of motors (106), which independently drive a plurality of wheels (107), can be operated within a desired operating range when driven by a target driving force calculated for each of the motors (106). The driving force command value calculation section (13) adjusts the distribution of driving force for each of the motors in accordance with the target driving force for each of the motors and with the operating status of each of the motors and calculates an actual driving force command value for each of the motors for the purpose of operating each of the motors within the desired operating range if the determination means determines that each of the motors cannot be operated within the desired operating range. The command value output section (14) outputs the driving force command value to each of a plurality of inverters (105). Therefore, a target vehicle motion can be maximally realized while appropriately maintaining the drive status of each of the motors.
