The present technology relates to a signal processing apparatus, a signal processing method, and a display apparatus that are able to provide suitable functionality according to applications. The signal processing apparatus provided by the present technology includes a signal processing section that acquires at least one of first information regarding a color of a video to be displayed on a panel section, second information regarding brightness of a screen of the panel section, and third information measured as a physical quantity related to the panel section, and that performs, on the basis of the acquired information, adaptive control of a voltage according to a load on and an application of the panel section. The voltage is used for driving the panel section. The present technology is applicable, for example, to a self-luminous display apparatus.

Signal processing apparatus, signal processing method, and display apparatus

The present technology relates to a signal processing apparatus, a signal processing method, and a display apparatus that may reduce the effect of deterioration in element of a display panel. Provided is a signal processing apparatus including a signal processing unit configured to acquire, in changing a video signal from a low luminance display signal to a high luminance display signal by luminance enhancement, an accumulated load increase amount obtained by measuring and accumulating amounts of increase in load on a display panel caused by luminance enhancement, and adaptively control, in reference to the accumulated load increase amount acquired, a first gain for improving luminance of the video signal, according to a degree of effect of deterioration in element of the display panel. The present technology is applicable to self-luminous display apparatuses, for example.

An image processing circuit includes: a detecting unit detecting pixel regions where luminance levels of image signals exceed a given luminance threshold; and a correcting unit applying basic gamma correction to image signals in regions other than the pixel regions detected, and applying luminance increasing gamma correction to image signals in the pixel regions detected. The luminance increasing gamma correction allows the luminance levels to be increased.

Image processing circuit and image display apparatus

It is determined whether or not an input video signal is a side panel signal, a letter box signal, or a full line signal. If the input video signal is a side panel signal or a letter box signal, when a multiple-picture displaying process or a reduced picture displaying process is performed, only a signal of an effective picture area is extracted. With only the signal of the effective picture area, the picture sizes are adjusted and the pictures are combined. Thus, even if an input video signal is a side panel signal or a letter box signal, the picture does not become small. In addition, when the reduced picture displaying process is performed, since a wasteful picture portion is not processed, the utilization efficiency of the screen is improved.

Picture processing apparatus and picture processing method

In an image display device and method, a moving picture is composed in a graphics generator with a still picture and graphics to obtain a composite image. A moving picture area, a still picture area and a graphics area of the composite image are specified and detected as binary detection signals. The detection signals are composed with one another in levels corresponding to the drawing areas to generate a composite detection signal. On the basis of the composite detection signal, the contrast, the luminance signal and the speed modulation signal are controlled for the drawing areas of a moving picture, a still picture and graphics. When the video signals of the moving picture plane and the non-moving picture planes are composed with one another and the composite image is displayed, the optimum image quality can be achieved in each of the moving picture and the non-moving picture areas of the composite image.
