Circuitry for adjusting luminance of a display device is provided. The circuitry includes a non-volatile memory array having a plurality memory cells configured to store luminance data of the display device, and a luminance adjusting circuit configured to receive image data to be displayed on the display device. The luminance adjusting circuit is coupled directly to the non-volatile memory array to receive the luminance data of the display device from the non-volatile memory array and adjust the image data based on the luminance data of the display device.

Provided is a signal processing device including a signal processing unit that, when increasing the luminance of an video signal from a low-luminance display signal to a high-luminance display signal, acquires information regarding at least one of luminance enhancement time obtained by measuring the time for enhancing the luminance on a display panel, the temperature rise amount of the display panel, and the feature amount of the video signal corresponding to video displayed on the display panel, and adaptively controls a first gain for enhancing the luminance of the video signal, according to the degree of influence on the temperature rise of the display panel, in reference to the acquired information. The present technique can be applied to a self-luminous display device, for example.

An image display apparatus includes a display, an input unit configured to receive input data including an input image in which a first dynamic range is defined and including information relating to luminance of the input image, and at least one processor or circuit for executing tasks of converting the first dynamic range into a second dynamic range having a maximum luminance lower than that of the first dynamic range, acquiring a user set maximum luminance of the second dynamic range, acquiring a maximum display luminance when the display unit displays the maximum luminance of the second dynamic range under a display condition set for the display unit, and generating a setting screen for a user setting. The setting screen displays information indicating a relative relation among the information relating to luminance acquired from the data, the user set maximum luminance and the maximum display luminance.

Methods and systems are described for condition mitigation. A computing device may display content. The computing device may determine that displaying and/or outputting the content may impact a person with a condition. The computing device may take an action to reduce an impact of the content on the person.

A sewing apparatus, includes a display input unit including a display unit configured to display an image of an input screen, and an input detection unit configured to detect an input operation on the input screen; and a control apparatus that performs display control of the display unit in response to the input operation. The control apparatus performs display control in which a background of the input screen is set to a dark color as a whole, a sewing pattern image displayed on the input screen is set to brightness higher than that of the background, and an operation unit that receives the input operation on the input screen is set to a color lighter than that of the background.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.
