Abstract
The present technology relates to a signal processing device, a signal processing method, and a display device for enabling more appropriate improvement of hold blur. There is provided a signal processing device including a detection unit that analyzes a video signal of content and detects an index that correlates with hold blur, a first calculation unit that calculates a light emission duty value of a self-luminous display panel on the basis of the detected index, and a second calculation unit that calculates a gain for luminance compensation on the basis of the calculated light emission duty value. The present technology can be applied to, for example, a self-luminous display device.
Claims20
A display comprising:
- a self-luminous display panel that includes a plurality of pixels that each includes a group of subpixels;
- and
- signal processing circuitry that is configured to:
- determine for display of video, when black insertion driving of the self-luminous display panel is to be employed;
- and
- determine for display of video, when normal driving of the self-luminous display panel is to be employed,
- wherein:
- the signal processing circuitry determines that the normal driving is to be employed when a still image portion of the video is determined,
- the signal processing circuitry determines that the black insertion driving is to be employed when a moving image of the video is determined, and
- the signal processing circuitry controls luminance compensation, during black insertion driving, in an average pixel level of the video and is employed such that the average pixel level includes two linear functions connected at an intermediate average pixel level, the first linear function has the average pixel level increasing at a first rate from a minimum average pixel level to the intermediate average pixel level with respect to decreasing light emission duty and the second linear function has the average pixel level increasing at a different second rate from the intermediate average pixel level to a maximum average pixel level with respect to further decreasing light emission duty.
