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 where it is inverted from a high level to a low level. Reference numerals 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 becomes low level, and the counter 76 has a count capacity corresponding to the number of memories of the frame memory M, and when the count-up state occurs, the counter automatically It goes into the reset state. Address decoder 77 is counter 7
The memory address corresponding to the count value of 6 is output, 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. M11-Mmn
Being accessed against. Address bus buffer 7
8 and the address bus buffer 80 are address bus buffers for selecting whether to output the output signals of the address decoders 77 and 79 to the address bus lines, respectively, and both of them have a high level signal applied to their C input terminals. Sometimes it outputs a signal to the address bus line. The signal L3 is applied to the C input terminal of the address bus buffer 80, and the signal L3 is applied to the address bus buffer 78.
Is applied via the inverter I73. M
Is a frame memory. The frame memory M performs a data bus signal write 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. Further, the processing circuit 53
Output terminal O1 of L3 for switching and driving the bus buffer 73 and the address bus buffers 78 and 80, respectively.
This is a terminal for generating a signal and is at a high level when writing data in the memory M, and at a low level when reading data from the memory M1.

Next, the image transfer circuit 5 configured as described above.

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

The period T during which the signal L3 is at low level
Since 1 is applied to the C input terminal of the address bus buffer 78 by inverting the signal L3 to the high level via the inverter I73, 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 becomes a high impedance state with respect to the address bus line,
No data is output. Also, the data bus buffer 7
Since a low level signal is applied to the C input terminal of 3 as well, it 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 this decode address outputs the content to the data bus line. In this state, the oscillator OSC
, 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 Is designated as 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,
From M13 ... to M21, M22, M23 ..., the read operation is performed, and when the reading of the entire frame memory is completed, the counter 76 is automatically reset and returns to the memory M11 again, and 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. The address data is also transmitted to the electronic finder drive circuit 58 via the address data bus line L7, and the electronic viewfinder drive circuit 58 drives and displays the electronic finder 4 according to the transmitted information.

Next, a period T2 in which image signals are output in time series from the signal line L1 when the accumulation of signals in the CCD area sensor 15 is completed will be described. In this case, the image signal is output as shown in FIG.
Switches from low level to high level. As a result, a high level signal is applied to the C input terminal of the data bus buffer 73, so that the bus buffer 73 outputs the digital conversion value output from the A / D converter 71 to the data bus line. Since a signal at a higher level than the signal L3 is applied to the C input terminal of the address buffer 80, the address decoder 79 addresses the specific memory in the frame memory via the address bus buffer 80, and the specified address is specified. The address memory 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 designated by the processing circuit is designated in the order of M11, M12, M13 ... M21, M22 ... And the A / D conversion value is written. In this case, the image output from the CCD area sensor 15 is written in the frame memory M so that the photographer can always see it as an upright image according to the state of the electronic finder 4. When the image information for one frame has been transmitted, the signal L3 is switched to the low level again, the write operation ends, and only the read operation is performed again until the next write 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.

FIGS. 8 to 10 show (a) the reading order of the subject image (not the image formed on the CCD area sensor 15 but the image of the subject viewed from the camera) performed by the CCD area sensor 15, and FIG. 7B is a plan view showing the order of transfer and writing to the frame memory M as FIG.

The order of reading the signals from the CCD area sensor is always the same, but in the present embodiment, they are all shown for comparison with the order of writing to the frame memory M.

In such a case, the reading of the output of the CCD area sensor 15 is sequentially performed from the reading start position shown as START1 in FIG. 8A to the reading end position shown as END1. That is, pixels in the horizontal direction are sequentially output, and when the first row is completed, the second row is sequentially output in the horizontal direction. The transfer of the image information for one frame is completed when the output is completed up to END1 in the last line. Image information is written in the frame memory M shown in FIG.
Starting from the memory at the starting position shown as START2 in (b), sequentially writing to the memory of the lateral memory, 1
After the end of the row, writing is sequentially performed in the horizontal direction on the second row, and writing is performed up to the memory at the end position shown as END2 of the last row. Further, as described above, the reading of the image information from the frame memory M is performed according to the count value of the counter 76 shown in FIG. 6 from M11 to M12 ... M1.
n, M21 ... M2n, M31 ... M3n ... Mm1 ... Mmn
