  • Patent number: 11146721
    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.

  • Patent number: 11140343
    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. To decrease the settling time of the column output line, the slew rate sensing and current source control circuitry may increase the magnitude of a bias current provided by the adjustable current source when the slew rate of the output voltage is above a threshold. When the slew rate of the output voltage is below the threshold, the bias current may revert to a lower magnitude to conserve power.

  • Patent number: 11134211
    Abstract: In image processing apparatus, a sample hold unit samples and holds an output signal of the image sensor. A timing signal generating circuit generates a sampling clock to specify a sampling timing of the sample hold unit. A controller sets a phase of the sampling clock to the timing signal generating circuit. In an adjustment process that adjusts the phase of the sampling clock, the controller (a) causes the image sensor to scan a reference board, (b) sets predetermined plural phases to the timing signal generating circuit in turn, (c) calculates average values of image data obtained correspondingly to the plural phases and calculates a value of a parameter that indicates a fluctuation width of the average values, and (d) sets the phase of the sampling clock as a phase corresponding to the smallest value of the parameter.

The images may have associated image metadata such as face detection information, camera settings, color and luminance histograms, and image classification information. Control circuitry in the electronic device may determine tone mapping parameters for the captured images based on the image metadata. The tone mapping parameters for a given image may be stored with the image in the metadata file. When it is desired to display the image, the control circuitry may apply a tone mapping process to the image according to the stored tone mapping parameters. The algorithm that is used to determine tone mapping parameters based on image metadata may be based on user preference data gathered from a population of users.
