Next, the details of the image transfer circuit 56 and the frame memory 57 shown in FIG. 5 and the relationship between the processing circuit 53 and the image transfer circuit 56 and the frame memory 57 will be described in detail with reference to FIG.

In FIG. 6, reference numeral 71 is an A / D converter for converting a pixel signal as an analog amount input from the CCD area sensor 15 into a digital value via the signal line L12, and 73 is an A / D converter. A bus buffer for selecting whether or not to output the digital signal output from 71 to the data bus line L8. When a high level signal is applied to the C input terminal, the signal is output to the data bus line.
The signal L3 is applied to the C input terminal of the bus buffer 73.

Next, the components of the frame memory 57 will be described. QSC is a pulse oscillator, and 76 is a counter, which is in a reset state when the L3 signal, which will be described later, is at a high level, and is in a counting state in which it is inverted from a high level to a low level. 77 and 79 are address decoders, and 78 and 80 are address bus buffers. The counter 76 constantly measures the pulse output from the pulse oscillator QSC when the L3 signal goes low. The counter 76 has a count capacity corresponding to the number of frames in the frame memory M. To the reset state.

The address decoder 77 outputs a memory address corresponding to the count value of the counter 76, and the address is accessed to each memory in the frame memory via the address bus buffer 78. Further, the address decoder 79 receives the address data input from the processing circuit 53 via the signal line L9, outputs the memory address corresponding to this value, and also outputs each memory address in the frame memory M via the address bus buffer 80. Access is made to M11 to Mmn.

The address bus buffer 78 and the address bus buffer 80 are address decoders 77 and 7, respectively.
9 is an address bus buffer for selecting whether or not to output the output signal of 9 to the address bus line, and outputs a signal to the address bus line when a high level signal is applied to its C input terminal. The signal L3 is applied to the C input terminal of the address bus buffer 80, and the signal of the signal L3 is applied to the address bus buffer 78 via the inverter I73.

M is a frame memory. The frame memory M performs a data bus signal writing operation when a high-level signal is applied to the RE input terminal, and outputs data when a low-level signal is applied. The signal line L3 is applied to the RE input terminal.
The output terminals O1 of the processing circuit 53 are connected to the bus buffers 7 respectively.
3, a terminal for generating an L3 signal for switching and driving the address bus buffers 78 and 80, which is at a high level when writing data in the memory M, and a memory M1
Becomes low level when data is read from.

Next, the image transfer circuit 5 configured as described above.
6, operations of the frame memory 57 and the processing circuit 53 will be described.

First, referring to FIG. 7, A / of the image transfer circuit 56
The L12 signal input to the D converter 71, the L22 signal of the clock input CLK input to the memory M, the processing circuit 53
The relationship with the L3 signal output from the output terminal O1 will be described.

The period T during which the signal L3 is at low level
1 is applied to the C input terminal of the address bus buffer 78 by inverting the signal L3 to a high level via the inverter I73, so that the address bus buffer 78 outputs the output signal of the address decoder 77 to the address bus line.

On the other hand, since the low level signal L3 is applied as it is to the C input terminal of the address bus buffer 80, it is in a high impedance state with respect to the address bus line and data is not output. Further, since the low level signal is applied to the C input terminal of the data bus buffer 73, the data bus buffer 73 is in a high impedance state with respect to the data bus line and data is not output.

The low level L3 signal is applied to the RE input terminal of the frame memory M, and the address decoder 77
Since the output data of the counter 76 is decoded, the memory corresponding to the decoded address outputs the content to the data bus line. In this state, the oscillator OSC
Since the counter 76 always outputs a repetitive pulse, and the counter 76 always performs a counting operation, for example, if the memory M11 of the frame memory M in FIG. 6 is read and the memory contents are output, the address decoder Specifies M12, and the memory M12 outputs the memory contents to the data bus L8.

In this way, as the designated addresses of the address decoder increase, the memories M11, M12, M13 are sequentially arranged.
.. to M21, M22, M23, .. The counter 76 is automatically reset at the time when the reading of the entire frame memory is completed, and the memory M1 is read again.
Returning to 1, the reading is continued similarly.

The data read from each memory is transmitted to the electronic finder drive circuit 58 via the data bus line L8. Further, the address data is also transmitted to the electronic viewfinder driving circuit 58 via the address data bus line L7, and the electronic viewfinder driving circuit 58
Displays the electronic finder 4 according to the transmitted information.

Next, a period T2 in which the image signal is output in time series from the signal line L1 when the accumulation of the signal in the CCD area sensor 15 is completed will be described. In this case, as shown in FIG.
Switches from a low level to a high level. As a result, since a high-level signal is applied to the C input terminal of the data bus buffer 73, the bus buffer 73 outputs the digital conversion value output from the A / D converter 71 to the data bus line.

Since a higher level signal than the signal L3 is applied to the C input terminal of the address buffer 80, the address decoder 79 addresses the specific memory of the frame memory via the address bus buffer 80, The memory of the designated address writes the output value of the data bus buffer 73 in synchronization with the rising edge of the L22 signal input to the CLK input terminal.

The address decoder 79 designates a specific memory in the frame memory according to the address data output from the processing circuit 53, and the A / D conversion value is written in this memory. The memory specified by the processing circuit is M11, M12, M
13 ... M21, M22 ... are designated in this order, and the A / D conversion value is written.

In this case, the image output from the CCD area sensor 15 is always viewed by the photographer as an upright image according to the state of the electronic viewfinder 4 and the frame memory M is displayed.
Will be written to. When the transmission of the image information for one frame is completed, the signal L3 is switched to the low level again, the writing operation is completed, and only reading is performed again until the next writing operation is started.

Next, writing of data according to the address output from the processing circuit 53 will be described with reference to FIGS. 8 to 10.
