A vision based light detection and ranging (LIDAR) system captures images including a targeted object and identifies the targeted object using an object recognition model. To identify the targeted object, the vision based LIDAR system determines a type of object and pixel locations or a boundary box associated with the targeted object. Based on the identification, the vision based LIDAR system directs a tracking beam onto one or more spots on the targeted object and detects distances to the one or more spots. The vision based LIDAR system updates the identification of the targeted object based on the one or more determined distances.

The texture recognition device has a touch side, and includes: a light source array, an image sensor array and a light valve structure; the image sensor array is configured to receive light emitted from the light source array and then reflected to the image sensor array by a texture for a texture image collection; the light valve structure is disposed on a side of the light source array close to a touch side and is configured to control a first region to be in a light transmission state in response to a control signal, so as to allow light emitted from the light source array to pass through the first region to form a first photosensitive light source in the light transmission state.

The invention relates to an image sensor, including a substrate, a unit pixel, a first polarizer, a second polarizer, and readout circuit. First, incident light is emitted to the image sensor, and the first and second polarizers convert incident light into first and second incident lights respectively. Then, the photoelectric conversion element of the unit pixel covered by the first and second polarizers respectively generates first and second electrons after receiving the first and second incident lights respectively. Afterwards, the readout circuit performs subtraction and integral of the first electron and the second electron to generate a voltage signal corresponding to the number of electrons in the actual signal. Finally, repeat the above steps. Thereby, the image sensor of the invention effectively increases the full well capacity of the equivalent unit pixel, so as to improve the signal-to-noise ratio of the image sensor of the invention.
