摘要： A rectangular moving region is properly determined. A retainer 604 retains an outputted moving region of time t and, at time t+1, provides it to a specified region feature detector 605. At time t+1, the specified region feature detector 605 applies the moving coordinates of time t provided by the judgment unit 603 to respective images of times t and t+1 to calculate feature data d(t) around the moving coordinates of time t and feature data d(t+1) around the moving coordinates of time t+1 and then provides the calculated data to a judgment unit 603. The judgment unit 603 judges whether there is a box, based on the feature data d(t+1).

摘要： Provided is a color adjustment apparatus, image display apparatus, and color adjustment method for adjusting color of a color image to enable easier distinction between objects shown in the image. A parameter defines a range of saturation to be adjusted within saturation before color adjustment and a range of change of the saturation after color adjustment compared to the saturation before color adjustment. The color adjustment apparatus calculates the saturation from an image signal, calculates the saturation after color adjustment according to the saturation before color adjustment such that the saturation in the range determined by the parameter increases/decreases by an amount determined by the parameter, and generates an image signal from the saturation after color change. By determining the parameter such that the saturation difference between prescribed colors is greater after color adjustment, the difference in color between a plurality of objects shown in the image is increased.

摘要： An object is to improve the visibility of the dark portion and to prevent the degradation of image quality caused by excessive correction. A reflectance calculation unit 27 is storing a parameter RGain for adjusting the amplitude of a reflectance component R. An illumination light correction unit 25 generates a corrected illumination light component L1 from an illumination light component L and a formula L1 = (log(LAmp*L+1))/(log(LAmp+1)). An image resynthesis unit 29 obtains a corrected illumination light component L' from L' = LGain*L1 + (1-LGain)*L. The image resynthesis unit 29 also calculates a corrected image Iout from the corrected illumination light component L' and the corrected reflectance R', as well as from a formula Iout = exp(logL' + RGain(logI-logL)). The value of the corrected illumination light component (L') is determined based on the ratio (LGain) at which the output value of the correction function (L1) and the original illumination light component (L) are combined. Thus, it is possible to obtain a natural image while maintaining contrast to some extent.
