摘要： The present disclosure relates to an image processing apparatus, an image processing method, and a program which can suppress degradation of image quality when power consumption of a display unit is reduced by reducing luminance of an image. A determining unit determines a reduction amount of luminance of a pixel based on characteristics of each pixel of an input image. A reducing unit reduces the luminance of the pixel of the input image by the reduction amount determined by the determining unit. The present disclosure can be applied to, for example, an image processing apparatus, or the like, which reduces luminance of a pixel based on characteristics of each pixel of an input image and displays the input image whose luminance is reduced.

摘要： An image processing apparatus, a method, and a program that enable an amount of code to be suppressed below a desired value with more reliability. An emergency mode determining section determines that the amount of code of a next picture is likely to exceed an upper limit if a target bit calculated by a rate controlling section exceeds a predetermined upper limit. If it is determined that the amount of code of the next picture is likely to exceed the upper limit, the code amount controlling section controls an orthogonal transducing section to replace a transform coefficient of a predetermined frequency component with zero, controls an intra predicting section to restrict intra prediction modes to be applied, and controls a mode determining section to restrict inter prediction modes to be applied. The prevent invention can be applied to an encoding apparatus.

摘要： Provided are a signal processing apparatus, a signal processing method, and an imaging apparatus for estimating depth with a high degree of accuracy from video signals of a plurality of cameras. The signal processing apparatus includes a detection unit that detects depth from video captured by a plurality of cameras, an estimation unit that estimates camera motion by detecting a camera position, a prediction unit that predicts present depth from camera motion and depth obtained previously, and a synthesis unit that synthesizes depth detected by the detection unit and depth predicted by the prediction unit on the basis of a result of estimating the amount of blur that occurs in each image captured by cameras. The amount of blur can be estimated using camera motion, previous depth information, and shutter time.

摘要： There is provided an apparatus and a method that perform a process of improving the quality of a low-quality image such as a far-infrared image. The apparatus includes an image correction unit that repeatedly performs an image correction process using a plurality of processing units in at least two stages. The image correction unit inputs a low-quality image to be corrected and a high-quality image which is a reference image. Each of the processing units in each stage performs a correction process for the low-quality image, using a class correspondence correction coefficient corresponding to a feature amount extracted from a degraded image of the high-quality image. A processing unit in a previous stage performs the correction process, using a class correspondence correction coefficient corresponding to a feature amount extracted from an image which has a higher degradation level than that in a processing unit in a subsequent stage.

摘要： Effective image correction processing for reducing flicker is executed according to characteristics of images, and an image to be displayed in a liquid crystal display apparatus is generated. Characteristic amount change rate data that is a change rate between a characteristic amount of a sample image and a characteristic amount of a sample image output to a liquid crystal display device is acquired in advance and stored in a storage unit. The correction parameter for reducing flicker is calculated on the basis of the characteristic amount of the image to be corrected and the characteristic amount change rate data of the sample images stored in the storage unit. The correction processing to which the calculated correction parameter has been applied is executed for the image to be corrected to generate a display image. As the characteristic amount, for example, the interframe luminance change amount, the interline luminance conversion amount, or the interframe motion vector is used.
