摘要： The resolution of a low-resolution image is made high and a stereoscopic image is displayed. Resolution is made high by super-resolution processing. In this case, the super-resolution processing is performed after edge enhancement processing is performed. Accordingly, a stereoscopic image with high resolution and high quality can be displayed. Alternatively, after image analysis processing is performed, edge enhancement processing and super-resolution processing are concurrently performed. Accordingly, processing time can be shortened.

摘要： A method for driving a display device is performed by the display device. The method includes: displaying a first image including user convenience information through a display panel; generating sensing data corresponding to a fingerprint sensing area by using a photoelectric sensor; and determining whether a sensed fingerprint corresponding to the sensing data is a fake fingerprint by comparing expected sensing light illuminance information based on the first image with sensed light illuminance information of the sensing data. The first image includes a first color pattern in the fingerprint sensing area of the display panel. A fake-determination image pattern includes the first color pattern and a second color pattern different from the first color pattern.

摘要： In some implementations, a mobile computing device may participate in the calibration of an output signal of a media device. This calibration process includes storing device-specific calibration data which is related to properties of a light sensor of the mobile device. The mobile device then detects of properties of light emitted by the display device during a presentation to obtain sensor values related to light emitted by the display device during the presentation. The calibration process may also ensure that the mobile device is proximate to the display device prior to obtaining the sensor values. The collected sensor values are adjusted using device-specific calibration data stored to the mobile device to normalize the sensor values relative to a baseline. These normalized sensor values are sent to the media device for use in adjusting the output signal based on the normalized sensor values.

摘要： An image processing apparatus comprises a receiver (201) for receiving an image signal comprising an encoded image. Another receiver (1701) receives a data signal from a display (107) where the data signal comprises a data field that comprises a display dynamic range indication of the display (107). The display dynamic range indication comprises at least one luminance specification for the display. A dynamic range processor (203) is arranged to generate an output image by applying a dynamic range transform to the encoded image in response to the display dynamic range indication. An output (205) outputs an output image signal comprising the output image to the display. The transform may furthermore be performed in response to a target display reference indicative of a dynamic range of display for which the encoded image is encoded. The invention may be used to generate an improved High Dynamic Range (HDR) image from e.g. a Low Dynamic Range (LDR) image, or vice versa.

摘要： To enable a good quality optimization of the luminances of an image, so that they are not only optimized for a particular maximum displayable luminance of a display, but also a particular amount of light in the viewing environment in which the display is watched, the inventor has invented a method of processing an input image to obtain an output image, wherein the input image has pixels which have input luminances which fall within a first luminance dynamic range (DR 1), which first luminance dynamic range has a first maximum luminance (PL_V_HDR), wherein a reference luminance mapping function (F_L) is received as metadata associated with the input image, wherein the reference luminance mapping function specifies a relationship between luminances of a first reference image and luminances of a second reference image, wherein the first reference image has a first reference maximum luminance and the second reference image has a second reference maximum luminance, wherein the input image is equal to one of the first reference image and the second reference image, wherein the output image is not equal to the first reference image nor the second reference image; wherein the processing comprises applying an adapted luminance mapping function (FL_DA) to the input pixel luminances, to obtain the output luminances, wherein the adapted luminance mapping function (FL_DA) is calculated based on the reference luminance mapping function (F_L) and a maximum luminance value (PLA), wherein the calculation involves finding a position on a metric which corresponds to the maximum luminance value (PLA), wherein a first endpoint of the metric corresponds to the first maximum luminance (PL_V_HDR) and a second endpoint of the metric corresponds to a maximum luminance of one of the first reference image and the second reference image not being equal to the input image, characterized in that maximum luminance value (PLA) is calculated based on a maximum luminance (PL_D) of a display which is to be supplied with the output image, and a black level value (b) of the display, wherein the calculation comprises applying an inverse of an electro-optical transfer function to the maximum luminance (PL_D), subtracting from the resulting value the black level value (b), and applying the electro-optical transfer function to the subtraction to obtain the maximum luminance value (PLA).

摘要： An image processing apparatus that handles a High Dynamic Range (HDR) signal is disclosed. The apparatus acquires a Perceptual Quantization (PQ) image comprised of a HDR signal conforming to Perceptual Quantization (PQ), and information relating to a maximum luminance value of the PQ image, which is associated with the PQ image. The apparatus converts the PQ image into a Hybrid Log Gamma (HLG) image comprised of an HDR signal conforming to Hybrid Log Gamma (HLG); converts the information relating to the maximum luminance value in the same manner as in the conversion of the PQ image to the HLG image; and associates the HLG image with the converted information relating to the maximum luminance value.
