That is, it is a diagram showing an example of displaying a pattern. Figure (A)
As shown in the figure, the remaining amount of tape and the running direction are displayed as characters at the right end on the screen. In this character display, at the start of the tape running, the tape remaining amount and the tape running direction are sequentially displayed for each field as shown by B1, B2 and B3 in FIG. When the tape travel is continued and when the tape is at the intermediate position, it is sequentially displayed for each field as indicated by C1, C2 and C3 in FIG. D) D1, D2 and D3 are sequentially displayed for each field as shown in D), and the remaining tape is exhausted.
At the time of D, the display of (D) blinks. Therefore, by such a display method, it is possible to display as if the tape reel is rotating. The END can be detected by optically detecting the transparent portion at the end of the tape, and the rotation state of the tape reel is determined based on the FG pulse and the rotation information of the reel motor. Can be determined. In the above display, when the display change of each mode is recorded (REC) / reproduced (PLAY), an image is displayed every two fields in order, and when fast forward (FF) / rewind (REW), one field is sequentially displayed. -Images are displayed for each field. FIG. 6 shows the procedure of the OSD display processing in step S2 of the above-described processing. This processing is performed by the system control circuit 13 as information processing means. First, a cassette tape detection process is executed (step S201), and the presence or absence of a cassette is determined (step S201).
202) If there is, the cassette state is detected (step S203). If there is no blank, a blank image is output (step S204), and the process returns to the main routine. Step S20
After detecting the cassette status in step 3, the output counters (# 1H, # 2H, # 3) corresponding to the respective tape displays in FIG.
H) is incremented, the field counter is incremented (step S205), and it is determined whether the mode is PLAY or REC (step S20).
6). Here, if PLAY or REC, the counter is 2
It is determined whether or not it is a field (step S207). N
If O, the process returns to the main routine. If YES, the value of the image output counter is determined (step S208). In step S206, if it is not the PLAY or REC mode, it is determined whether the mode is the FF or the REW mode (step S209). If YES, the counter is reset (step S210), and the process of step S208 is performed. Then, if the mode is not the FF or REW mode, a blank image is output (step S211), and the process returns to the main routine. In step S208, when the value of the image output counter is # 1H, the cassette state is determined (step S212), and B1 in FIG. 5 is output at the start position of the tape drive (step S213), Then, C1 is output (step S214), D1 is output near the end (step S215), and the display of D1 blinks at the end point position (step S216). If the value of the image output counter is # 2H in step S208, the cassette state is determined (step S218), and the cassette position is determined at the initial position in FIG.
B2 is output (step S219), C2 is output midway (step S220), D2 is output near the end (step S221), and D2 blinks at the end point position (step S222). Further, if the value of the image output counter is # 3H in step S208, the cassette state is determined at the same time (step S223), and B3 in FIG. 13 is output at the beginning of the tape (step S224).
C3 is output on the way (step S225), D3 is displayed near the end (step S226), and B3 blinks at the end point (step S227). In step S208, the value of the image output counter is # 1,
If it is not # 2 or # 3, the image output counter is reset (step S228), the counter is reset (step S229), and the process returns to the main routine. FIG. 7 shows an example in which the character display is shown as a bit image pattern. A display pattern as shown in FIG. 7 is written as a bit image pattern in a RAM area of the character signal generation circuit 12 in FIG. 1 by a signal from a microcomputer (system control circuit 13) at the time of initial setting. When a mask ROM pattern is written on the character generator element, a desired character is set in a desired pattern as described above. As described above, in the camera-integrated image recording apparatus having the tape remaining amount display function according to the present embodiment, the tape remaining amount and the tape running mode are graphically displayed. Therefore, at first glance, the photographer can recognize that the display is related to the tape running. In addition, since both the tape remaining amount display and the tape running mode display are used, the display space in the EVF is smaller than in the case of displaying each of them, so that the subject can be checked when shooting. There is no hindrance. According to the present invention, the remaining amount for recording on the image recording medium is graphically displayed in the EVF, so that the photographer can recognize the information at a glance, The operability at the time of shooting can be improved.
