A processor for use in an electronic device capable of displaying, having capability of switching a refresh rate for refreshing a display panel. The processor can dynamically transition between different states/scenarios in response to different triggering events. The processor can include an image stream consumer, configured to receive an input image stream and outputting an output image stream; a refresh rate selection controller, configured to select a refresh rate from a plurality of refresh rates in response to a monitoring of a current state/scenario; and a display controller, configured to receive the output image stream from the image stream consumer and transmit image data in the output image stream to a driving device, and in response to the selection by the refresh rate selection controller, control the driving device to refresh a display panel with the selected refresh rate.

Processor for use in dynamic refresh rate switching and related electronic device

A processor for use in an electronic device is provided. The electronic device is capable of displaying and the processor has capability of switching a refresh rate for refreshing a display panel of the display device. The processor comprises: a refresh rate selection controller and a display controller. The refresh rate selection controller is configured to dynamically select one from a plurality refresh rates. The display controller is configured to control a driving device to refresh the display panel with the selected refresh rate and determine whether to adjust a data transmission rate over an interface between the processor and the driving device according to the selected refresh rate.

Processor for use in dynamic refresh rate switching and related electronic device and method

An electronic device is disclosed. The electronic device comprises a transmitter, a converter, and a receiver. The transmitter transmits data and a control signal. The converter receives the control signal from the transmitter and converts the control signal. The receiver receives the data from the transmitter via a data bus isolated from the converter and receives the converted control signal from the converter. The data transmitted from the transmitter is directly electrically connected to the receiver.

Systems and methods for control signal and data transmission between various types of electronic modules

An apparatus for capturing and storing real-time images is provided. A camera module records frames corresponding to sensed light, outputs pixel data of the frames on a data bus, and generates synchronization control signals to control the synchronized transmission of the frames. An interrupt controller receives the synchronization control signals and correspondingly generates interrupt signals. A processing unit receives the interrupt signals, fetches the pixel data of the frames on the data bus according to at least one of the interrupt signals, and stores the fetched pixel data in a memory device.

Apparatuses for capturing and storing real-time images

A luminance compensation apparatus and method applied to an electronic apparatus are disclosed. The luminance compensation apparatus includes an environment detector, a processor, and a luminance compensation unit. The environment detector is for detecting environment luminance and outputting a luminance detection value accordingly. The processor is coupled to the environment detector for outputting a compensation parameter according to the luminance detection value. The luminance compensation unit is coupled to the processor for compensating luminance values of pixels of the multimedia data according to the compensation parameter and outputting compensated multimedia data. The method includes detecting environment luminance and obtaining a luminance detection value accordingly; generating a compensation parameter according to the luminance detection value; and compensating luminance values of pixels of the multimedia data and providing compensated multimedia data according to the compensation parameter.

Luminance compensation apparatus and method

The invention discloses a general purpose interface controller, including a slave interface controller and a master interface controller, used to exchange data among master devices and slave devices in an electronic device. The slave interface controller receives data and a first control signal from one of the master devices, and converts the first control signal to a request signal. The master interface controller receives the data and the request signal from the slave interface controller, converts the request signal to a second control signal recognized by at least one of the slave devices, and forwards the data and the second control signal to the slave device.
