Abstract: An image sensor, an arrangement structure and a control method are provided. The image sensor comprises pixel units arranged in an array. Each pixel unit comprises a conversion output module, a first-mode operation module, and a second-mode operation module. The conversion output module outputs a first set of signals comprising a first reset signal and a pixel signal, and outputs a second set of signals comprising a second reset signal and an overflow signal. The first-mode operation module is connected to the conversion output module. In a first mode, the first-mode operation module stores and reads out at least one of the first set of signals and the second set of signals. The second-mode operation module is connected to the conversion output module. In a second mode, the second-mode operation module reads out at least one of the first set of signals and the second set of signals.

Abstract: This application relates to the field of terminal technologies, and provides a Bluetooth communication method, a wearable device, and a system, to avoid always maintaining an HFP connection, so as to avoid an unnecessary delay or a call error caused when an electronic device processes a voice message. The Bluetooth communications system includes an electronic device and a wearable device, and an HFP connection is established between the electronic device and the wearable device. When the electronic device meets a preset condition, the HFP connection is automatically disconnected. The electronic device sends a first notification to the wearable device after receiving an incoming call, to reestablish the HFP connection. In this case, the electronic device may answer the incoming call by using the wearable device.

Abstract: Disclosed are a method, system and electronic device method for adaptively adjusting frequency of a switching power supply. The method includes: obtaining a SNR threshold, obtaining a SNR value of an AM/FM radio demodulator; when the SNR value is smaller than a SNR threshold, outputting a plurality of control signals to the switching power supply, obtaining a plurality of corresponding operation frequencies of the switching power supply; obtaining a plurality of SNR values of the AM/FM radio demodulator at each of the plurality of operation frequencies, obtaining a maximum SNR value among the plurality of SNR values; outputting a control signal corresponding to the maximum SNR value, controlling the operation frequency of the switching power supply with the control signal; obtaining the SNR value of the AM/FM radio demodulator at a preset time period, and comparing the SNR value to the SNR threshold.

Abstract: A CMOS image sensor with an imaging array of pixels containing selected pixels wherein illumination is blocked and light scattered from an adjacent pixel is collected. The signal from the selected pixels is resilient against saturation and thereby contributes to increased dynamic range of the imaging signal. The image sensor may be incorporated within a digital camera.
