Abstract: In a communication system comprising a first communication apparatus and a second communication apparatus, the first communication apparatus transmits a first notification for connection processing in short-range wireless communication during an operation in a first power mode, and transmits a second notification, different from the first notification, for the connection processing in the short-range wireless communication during an operation in a second power mode in which power is saved more than in the first power mode. The second communication apparatus starts, if the first notification is received, the connection processing at an arbitrary timing, and starts, if the second notification is received, the connection processing at a timing restricted as compared to the case in which the first notification is received.

Abstract: An image sensor may include an array of imaging pixels arranged in rows and columns. Each column of imaging pixels may be coupled to a respective column output line. Each column output line may be coupled to readout circuitry that includes an adjustable current source, sample and hold circuitry, and slew rate sensing and current source control circuitry.

When the slew rate of the output voltage is below the threshold, the bias current may revert to a lower magnitude to conserve power.
