An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.

This disclosure relates to a video compression method, apparatus, and device, and a medium. The method includes: obtaining a video frame, where the video frame includes a first dynamic group of pictures and a second dynamic group of pictures; extracting a first I frame in the first dynamic group of pictures, and extracting a second I frame in the second dynamic group of pictures; deleting duplicate data between the first I frame and the second I frame, to obtain a target I frame; and compressing the target I frame. The duplicate data between the first I frame and the second I frame is deleted, and this does not affect integrity of data of the video frame.

A portable electronic device, and an image-capturing device and an assembly method thereof are provided. The image-capturing device includes a carrier substrate, an image sensing chip, a filter element and a lens assembly. The carrier substrate has a through opening and a recessed space. The image sensing chip is disposed on the bottom side of the carrier substrate. The filter element is disposed in the recessed space of the carrier substrate, so that all or a part of the filter element is accommodated in the through opening. When at least one microparticle with a maximum particle size between 5 μm and 25 μm is located on the filter element, a shortest distance between the filter element and the image sensing chip is between 30 μm and 200 μm, so that the image sensing chip cannot capture a light spot generated due to blocking of the microparticle.

A semiconductor device according to the present disclosure includes: a first charge accumulation unit capable of accumulating a charge; a first initialization unit that is connected to the first charge accumulation unit and initializes the first charge accumulation unit; and a first voltage switching unit that is connected to the first initialization unit and is capable of selectively supplying a first voltage and a second voltage different from the first voltage to the first initialization unit.

In a solid-state imaging element equipped with per-column ADCs, noise is reduced. A test signal source generates a test signal of a predetermined level. An analog-to-digital converter increases/decreases an analog signal according to an analog gain selected from among a plurality of analog gains, and converts the increased/decreased analog signal to a digital signal. An input switching section inputs, as the analog signal, either a test signal or a pixel signal to the analog-to-digital converter. A correction value calculation section obtains, on the basis of the test signal and the digital signal, a correction value for correcting an error in the selected analog gain, and outputs the correction value. A correction section corrects the digital signal according to the outputted correction value.

A long-baseline and long depth-range stereo vision system is provided that is suitable for use in non-rigid assemblies where relative motion between two or more cameras of the system does not degrade estimates of a depth map. The stereo vision system may include a processor that tracks camera parameters as a function of time to rectify images from the cameras even during fast and slow perturbations to camera positions. Factory calibration of the system is not needed, and manual calibration during regular operation is not needed, thus simplifying manufacturing of the system.
