A depth sensing system and a depth sensing method are provided. The sensing system includes depth sensing module and a processor for performing the sensing method. The depth sensing method incudes: obtaining a sensed target data set via a depth sensing module; calculating a period number corresponding to a measuring pixel; and calculating an actual range value or an actual depth of the measuring pixel in accordance with a period number and a range value of the measuring pixel. The step of calculating the period number of the target data set includes: calculating a spatial ratio in accordance with the position values of the pixel of optical center and measuring pixel, and a focal length of the depth sensing module; calculating a basic range in accordance with the spatial ratio and an unit depth; and calculating the period number corresponding to the measuring pixel.

Depth sensing system and depth sensing method

The device includes a projecting device, an image sensor and a computing circuit. The projecting device provides a light beam having a predetermined pattern that is projected onto an object. The image sensor receives the light beam reflected from the object to generate an image. The computing circuit compares the image with a first ground-truth image and a ground-truth image to generate a first depth value and a second depth value respectively. The first and second depth values are combined to generate a depth result.

Device and method for sensing depth

A display apparatus includes a backlight module with backlight zones, a panel over the backlight module, and a circuit configured to generate compensated pixel data for the panel based on image data and an arrangement of the zones of the backlight module, in which the image data has image areas respectively corresponding to the backlight zones. For a first image area being a low-luminance image area and a luminance intensity of a first zone of the zones corresponding to the first image area being less than a luminance intensity of a second zone corresponding to a second image area neighboring the first image area, the circuit performs first pixel compensation for high-luminance pixels in the second image area and second pixel compensation on low-luminance pixels in the second image area, in which the second pixel compensation is greater than the first pixel compensation.

A display device includes a display panel and a circuit. For a first sub-pixel, the circuit obtains a corresponding second sub-pixel. The circuit calculates a first compensation value according to the grays levels of the first sub-pixel and the second sub-pixel, and calculates a second compensation value according to the polarity states of the first sub-pixel and the second sub-pixel and the difference between the gray levels of the two sub-pixels. The circuit also calculates a gain according to the position of the first sub-pixel, compensates the gray level to the first sub-pixel according to the first compensation value, the second compensation value and the gain to obtain an output gray level, and drives the first sub-pixel according to the output gray level.
