Is a video processing unit, which inputs the video signal received and demodulated by the tuner unit 10, and performs adjustment processing of the amplitude of the video signal, the DC level of the signal, the color tone, the hue, or the frequency characteristic of the signal. An output unit 12 inputs the video signal from the video processing unit 11 to the video circuit of the personal computer body. A tuner control unit 13 adjusts the reception channel or tuning frequency of the tuner unit 10. A video control unit 14 controls the signal processing of the video processing unit 11. A control unit 15 controls each unit of the expansion unit (b).

Next, the operation of the image adjusting system according to the present invention will be described. First of all, when setting the receiving channel of the tuner unit 10, from the input unit 1 on the personal computer side (a),
For example, the "channel setting" preset by the operation of the keyboard or the like and the area code set for each living area are input with reference to a separately provided table or the like. Storage unit 2
The area stores codes (area codes) set for each area in accordance with the television broadcast channel plan, channel numbers corresponding to the codes, and the like. The signal from the input unit 1 is input to the discrimination unit 3 via the control unit 6,
A corresponding signal is discriminated from the data read from the storage unit 2 via the control unit 6, and is output from the output unit 4 to the expansion unit side (b) via the control unit 6. On the other hand, the signal from the discriminating unit 3 is input to the display unit 5 via the control unit 6 to display the channel number and the like set on the screen of the monitor of the personal computer. The data from the storage unit 2 is serial command data and is output in synchronization with the clock signal.

In the memory section 8 on the expansion unit side (b),
Broadcast channels and frequencies of each channel are stored in advance for each area code. The signal from the output section 4 on the personal computer main body side (a) is input from the input section 7 on the expansion unit side (b) and is input to the discrimination section 9 via the control section 15. Then, the data of each channel corresponding to the corresponding area code is read from the data read from the memory unit 8 via the control unit 15, and the tuner control unit 13 sets the reception channel of the tuner unit 10 based on this data. In this case, for example, the vacant channels are skipped, and only the broadcasted channels are packed and set in numerical order.

Alternatively, in the case of adjusting the frequency of the receiving channel of the tuner section 10, the preset "channel adjustment" or the like is input from the input section 1 of the personal computer main body side (a) by operating the keyboard or the like. . In the storage unit 2,
For example, the reception band as shown in FIG. 2 (VHF low channel, VHF high channel, UHF channel, etc.)
Display data, data for displaying the adjustment frequency, operation mode (adjustment speed low, medium, high, etc.) data and display data, etc. are stored, and the control unit 6 is controlled according to the signal from the input unit 1.
