Abstract: An imaging apparatus is equipped with an analog block, an imaging condition determination section, and an analog gain control section. Current consumption of the analog block changes in accordance with an analog gain, which is an amplification ratio of outputs of an imaging device. The imaging condition determination section determines imaging conditions, including the analog gain, in accordance with the brightness of an imaging object. Depending on a state of the imaging apparatus, the analog gain control section alters the analog gain determined by the imaging condition determination section so as to reduce the current consumption of the analog block. Thus, in this imaging apparatus, the current consumption of the analog block may be reduced by the performance of control that alters the analog gain in accordance with the state of the imaging apparatus. Thus, the state of the imaging apparatus may be regulated.

Abstract: An electronic device includes a wireless communication circuit section which intermittently executes connection with another electronic device by wireless communication, a sensor section which outputs sensor data related to the movement of the electronic device, and a control section. When the electronic device is making a periodic movement, the control section acquires the cycle of the periodic movement of the electronic device based on the sensor data, and causes the wireless communication circuit section to set connection timing for connecting the electronic device with the another electronic device by the wireless communication to periodic timing based on the cycle.

Abstract: An analog-to-digital conversion apparatus includes a controller. The controller is configured to execute first control processing to cause the selection circuit of each of the circuit sets to perform switching which involves cyclically changing an analog signal to be selected at sampling timings with a predetermined time difference, and second control processing to calculate a digital data item at a reference sampling timing for each of the analog signals based on digital data items obtained from the analog-to-digital converter of the plurality of circuit sets, in accordance with the digital data items with the predetermined time difference, the sampling timings, and the time difference.
