Note that it is also possible to perform the above image processing by a processing portion which is provided separately from the first processing portion 33. One or more of the above image processing may be performed by the second processing portion 40.
The receiving portion 34 has a function of receiving data or a control signal input from the outside. The input of the data or the control signal to the receiving portion 34 can be performed with an arithmetic processing device 50, a remote controller, a portable information terminal (e.g., a smartphone or a tablet), an operation button or a touch panel provided on the display portion 20, or the like.
Note that the arithmetic processing device 50 can supply a weight coefficient used in the second processing portion 40 or the like to the display system 10. As the arithmetic processing device 50, a calculator having high arithmetic processing properties, such as a computer, a server, or a cloud, can be used. The arithmetic processing device 50 can supply a weight coefficient obtained by learning to the second processing portion 40 through the receiving portion 34.
The interface 35 has a function of performing, as appropriate, signal processing on the data or the control signal received by the receiving portion 34 and outputting it to the control portion 36.
