摘要： A communication circuit includes a first buffer configured to output a signal indicative of a first logic state or a second logic state, a signal in which the first logic state and the second logic state are defined being input to the first buffer, a second buffer configured to output a signal indicative of any one of the first logic state, the second logic state, and a third logic state, the signal output from the first buffer being input to the second buffer, and a monitoring circuit configured to monitor a logic state indicated by the signal output from the first buffer and cause the second buffer, in a case where the logic state does not change during a first period, to output the signal indicative of the third logic state.

摘要： An image processing device includes a memory that stores a program and a processor that executes the program stored in the memory to perform a process. The process includes obtaining input image data that is generated by combining, in a horizontal direction, an effective display area of first image data and an effective display area obtained by expanding an effective display area of second image data in the vertical direction, the vertical size of the second image data being smaller than the vertical size of the first image data; and generating second output image data corresponding to the second image data by reducing the vertical size of second intermediate image data among first intermediate image data and the second intermediate image data, which are obtained by dividing the input image data in the horizontal direction, based on the vertical size of the effective display area of the second image data.

摘要： With respect to a phase locked loop (PLL) circuit that receives a first reference clock and generates an output clock, the PLL circuit includes a delay circuit that delays the first reference clock to generate a second reference clock, a feedback circuit that generates a control signal based on a phase difference between the second reference clock and a feedback clock, an oscillator that oscillates at a frequency determined based on the control signal to generate the output clock, and a divider that divides the output clock in the on state. The PLL circuit switches between a first mode and a second mode, the feedback clock in the first mode is a signal obtained by retiming an output of the divider with the output clock, and the feedback clock in the second mode is a signal obtained by retiming the first reference clock with the output clock.

摘要： A relay device includes: a case which holds a mobile terminal, the mobile terminal being attachable to and detachable from the case; a first interface to which the mobile terminal held in the case is connected; a second interface with which the external display device is connected; and a controller housed in the case. The controller includes: an obtainer which obtains a video signal and first notification information from the mobile terminal via the first interface; and a superimposer which superimposes second notification information on the video signal based on the first notification information, and outputs the video signal on which the second notification information is superimposed to the external display device via the second interface. The second notification information is obtained by at least one of deletion or replacement of at least a portion of the first notification information.
