〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a camera that records information on the orientation of the screen, shooting date information, and recording instruction information thereof on a magnetic recording layer on a photographic film. The taking lens 10 includes an optical system 10a and a lens barrel 10b that holds the optical system 10a. The taking lens 10 is moved back and forth along the optical axis 11 by a manual or autofocus mechanism to perform focus adjustment. Behind the taking lens 10, a shutter mechanism 12 for performing program control is arranged. The shutter mechanism 12 includes, for example, two shutter blades 13 and 14, and each of the shutter blades 13 and 14.
Are formed with notches 13a and 14a, respectively. These shutter blades 13 and 14 are moved by a movable pin 16 by a control mechanism 15.
When moving toward the fixing pin 17, the notches 13a and 14a are overlapped by moving in a direction away from the fixing pin 17 as a center. A portion where the notches 13a and 14a overlap is opened, and light passing therethrough is incident on the photographic film 18, where the subject is photographed.

Further, inside the camera body (not shown), a top and bottom sensor 20 for detecting the top and bottom of the camera is arranged. This vertical sensor 20 has four mercury switches 20a to 20d
These mercury switches 20a to 20d are turned on.
・ Detects the camera orientation from OFF. Note that, instead of the mercury switches 20a to 20d, another switch may be used to detect the orientation of the top and bottom. The ON / OFF signals from the switches 20a to 20d of the vertical sensor are sent to the vertical signal generating circuit 21. The top and bottom signal generation circuit 21 includes switches 20a to 20d.
The data representing the orientation of the camera is generated from the ON / OFF signal of the camera and sent to the magnetic recording unit 22. The magnetic recording unit 22
The head position data is converted into a magnetic recording signal, and the magnetic recording head 23 is driven based on the signal. As a result, the orientation data at the time of photographing by the camera is recorded on the magnetic recording layer of the photographic film 18 when the photographic film is advanced.

In addition, the camera is provided with an automatic date mechanism 25, which outputs shooting date data to the magnetic recording unit 22. As is well known, the automatic date mechanism 25 can output photographing time data instead of the photographing date by switching a switch. Further, it is possible to output two data of a photographing date and a photographing time.

Further, the camera is provided with a touch panel sensor 27 for inputting recording instruction information and a back side print designation switch 28 for inputting back side printing on the shooting date. The touch panel sensor 27 is divided into nine input areas 29 arranged in a 3 × 3 matrix. This input area 29
Corresponds to each shooting area obtained by dividing the recording position on the screen on the shooting date into nine pieces. Then, the subject is observed through a finder (not shown) of the camera to check the output position on the screen of the shooting date, and the input area 29 corresponding to the output position is displayed.
By touching with a finger, the recording position on the screen of the shooting date is designated. If it is desired to record the shooting date in the middle of a plurality of areas, the plurality of areas are selected.

In order to confirm the designated input area, it is convenient to make the touch panel sensor 27 transparent, mount a light emitting panel below which a plurality of emitting diodes are arranged in a matrix, and display the selected input area with light emission. Also, if grid lines are applied to the optical elements in the viewfinder so as to correspond to the shooting area, it is convenient to easily know in which shooting area the shooting date will be output when observing the viewfinder. .

The signal from the touch panel sensor 27 is converted into recording instruction data by the recording instruction signal generation circuit 30 and sent to the magnetic recording unit 22. The magnetic recording unit 22 exchanges the photographing date data, the photographing time data, and the recording instruction data into a magnetic recording signal in the same manner as the orientation information of the top and bottom, and exchanges the magnetic recording signal with the magnetic recording head 23 for the photographic film 18. Record on the recording layer.

FIG. 2 shows an example of a photographic film in which the data of the orientation of the top and bottom, the date of photographing, and the recording instruction thereof are recorded. This photo film 18 has perforations 18b at regular intervals.
The perforation 18b is detected by a sensor of the winding stopping device, so that one frame is fed. Further, a screen 18a is recorded by photographing on the surface of the photosensitive emulsion layer positioned by the perforation 18b.
On the opposite side of the perforation 18b, a magnetic recording layer 18c in which the above data is written is formed in a band shape.

FIG. 3 shows a photographic printer. The white light emitted from the light source 35 passes through a cyan filter 36, a magenta filter 37, and a yellow filter 38, and then enters a mixing box 39. These color correction filters 36-38 are
The insertion amount of the optical path 41 is adjusted by the filter adjustment unit 40,
Thereby, the three-color light component of the printing light and the intensity thereof are adjusted. In the mixing box 39, diffusion plates are attached to both ends of a rectangular tube whose inner surface is a mirror surface.

The film carrier 43 is arranged at the printing position, the developed photographic film 18 is set, and irradiated with the light transmitted through the mixing box 39. In order to ensure the flatness of the photo film 18, a film mask 44 is provided above the print position. This film mask
As is well known, 44 has an opening corresponding to the size of a frame, and is lifted up by a solenoid (not shown) when the photographic film 18 is transferred, and is pressed down on the photographic film 18 during printing.

A magnetic reading head 45 is arranged in front of the printing position, and when the photo film 18 is sent to the printing position, the top and bottom direction data, shooting date data, shooting time data, shooting date and the like recorded on each frame are recorded. The recording instruction data is read, and this signal is sent to the magnetic reading unit 46. Magnetic reading section
The 46 converts the signal from the read head 45 into various data and sends it to the arithmetic unit 47 and the controller 52.

A scanner 50 including a lens 48 and an image area sensor 49 is disposed obliquely above the print position, and measures the transmitted light of each point of the frame set at the print position. The signal from the scanner 50 is sent to a signal processing circuit 51, where the signal is subjected to logarithmic conversion and digital conversion, and then a density signal at each point is sent to a calculation unit 47. Arithmetic unit
47, as will be described in detail later, determines the orientation of the screen based on the orientation data, selects a pattern area (see FIG. 4) corresponding to the orientation of the screen, and uses this pattern area to determine the feature value. Is calculated, and then the exposure amount is calculated. The controller 52 adjusts the set positions of the color correction films 36 to 38 according to the three color printing exposure amounts calculated by the arithmetic unit 47. Further, the controller 52 controls each unit such as the shutter driving unit 53 in addition to the filter adjusting unit 40.

A printing lens 56 is disposed above the print position, and enlarges and projects an image of a frame on color paper 58 disposed behind a paper mask 57. This baked lens 56
A shutter 59 whose opening and closing is controlled by a shutter driving unit 53 is disposed between the shutter 59 and the color paper 58.

In addition, a data recording unit 60 is disposed at the printing position of the color paper 58 and at a position adjacent thereto. The data recording unit 60 is for recording data such as a photographing date and a photographing time on the color paper 58, and a transparent LCD unit 61 disposed at a printing position.
And an LED unit 62 arranged next to the print position,
Printing unit 63 arranged on the back side of color paper 58
It is composed of

The LCD unit 61 includes normally open type liquid crystal cells arranged in a matrix. This LCD unit 61
It is controlled by the recording control unit 65 via the driver 61a. The recording control unit 65 drives predetermined liquid crystal cells based on the photographing date data and the recording instruction data from the magnetic reading unit 46 and the top-and-bottom direction data to change them from the light transmitting state to the light shielding state. Thus, the photographing date is displayed at the designated position on the screen in the designated direction at the time of printing exposure of the frame to be printed. The direction of the shooting date is the same as the direction of the screen based on the upside-down direction data. As a result, a part of the frame is shielded from light by the light shielding pattern, and the shooting date is imprinted on a desired position on the screen.

The LED unit 62 has light emitting elements arranged in a matrix, and is similarly controlled by the recording control unit 65 via the driver 62a. The exposure control unit 65 drives each light emitting element based on the photographing date data and the recording instruction data, and burns the photographing date in a designated direction at a designated position of a burn-exposed frame.

The proper use of the LCD unit 61 and the LED unit 62 is performed using photometric data of a frame to be printed. That is, the color density on the print is determined using the exposure amount and the correction data.
Using the D unit 62, the shooting date is printed in black on the print. Conversely, when the entire print is dark, the shooting date is output as white on the print using the LCD unit 61. Thus, the LCD unit 61 and the LED unit
By properly using 62, the shooting date can be clearly recorded in all frames. LC at the time of burning each data
By changing the three-color light components of the D unit 61 and the LED unit 62, the display color of data can be changed.

The printing unit 63 is driven by the recording control unit 65 when the recording instruction data or the input instruction on the photographic printer specifies backside printing, and prints the shooting date, shooting time data, color correction conditions, frame number, and the like on a color paper. It is printed on the back of 58 frames to be printed.

Next, the operation of the above embodiment will be described. When taking a picture, the composition is determined for the camera subject. At this time, the orientation of the camera at the time of shooting is detected by the orientation sensor 20, and the orientation signal generation circuit 21 sends data representing the orientation of the screen to the magnetic recording unit 22 based on the orientation. Also,
The shooting date data is stored in the magnetic recording unit 22 by the automatic date mechanism 25.
Sent to Further, a recording instruction signal of the photographing date is input by operating the touch panel sensor 27 or the back side print designation switch 28, which is converted into recording instruction data by the signal generation circuit 30 and input to the magnetic recording unit 22. When there is no input from the touch panel sensor 29, the recording instruction data of the photographing date is sent to the magnetic recording signal generator 21 only to record the photographing date and photographing time data, and is recorded on the magnetic recording layer 18c.

When the shutter button is pressed down after the composition is determined, the control mechanism 15 reciprocates the drive pin 16 to open and close the shutter mechanism 12 to perform photographing. At the time of film frame feeding after the operation of the control mechanism 15, these data are recorded on the magnetic recording layer 18c of the film 18 by the magnetic recording section 22 via the magnetic recording head 23. When the photographing of one photo film 18 is completed, the photo film 18 is taken out of the camera and submitted to a photo processing laboratory.

The photographic film 18 that has been developed by a known film processor at a photographic development station is set on a film carrier 43 of a photographic printer as shown in FIG. Then, the film 18 is fed frame by operation of a frame feed key or the like, and the frame to be printed is set at the print position by the quantitative feed after detecting the perforation 18b. At the time of feeding the film, each data is read by the magnetic reading head 45.

When frame 18a is set to the print position, scanner 5
0 measures the transmitted light of red, green, and blue for each point of the frame 18a. The photometric values of these three colors are used for signal processing circuit 51.
Is converted to a density and sent to the calculation unit 47. Arithmetic unit 47
Selects an area pattern based on the data of the orientation at the time of shooting. FIG. 4 shows these area patterns 71 to 74.
An example is shown below. The area patterns 71 to 74 are obtained by extracting the position of the main part, for example, the area of the face of a person, from the statistical data of a large number of frames, 75 is the main area, and 76 is the peripheral area excluding this. Show. Then, the area pattern 71 adopted in the case of the normal shooting frame is shown in FIG.
The area pattern 72 used in the case of the normal shooting frame and the frame shot with the top and bottom reversed is shown in FIG. 7B, and the area pattern 73 of the vertical frame shot with the camera upright is shown in FIG. The area pattern 74 in the case of a vertical frame shot with the camera turned upside down is shown in FIG. In addition, in addition to these patterns, an area pattern for a scenery frame may be prepared in accordance with the orientation of the top and bottom, and these may be selected. In this case, it is preferable to record scene identification data for identifying portrait photography or landscape photography on the magnetic recording layer of the film. Further, instead of the scene identification data, distance measurement data of the main subject of the photographing lens may be used to identify a landscape scene or a portrait scene.

The calculation unit 47 calculates the exposure control feature value _Di (i represents one of red, green, and blue) based on the selected area pattern by the following equation.

D _i = (DC _i + DS _i ) / 2 (1) Here, each symbol is as follows.

DC: Average density of the main area 75 shown in FIG. 4 DS: Average density of the peripheral area 76 of the screen shown in FIG. , for determining the average of the large perimeter area than half compared to the entire screen becomes an emphasizing a main part area exposure control feature value D _i is obtained.
Instead of equation (1), so as to change the weighting according to the following equation, it may be determined exposure control feature value D _i.

D _i = K · DC _i + (1−K) DS _i (2) Further, the arithmetic unit 47 calculates the printing exposure amount from the characteristic value D _i by the following equation.
Calculate E _i .

logE _i = α _i · (D _i −DN _i ) + β _i (3) where the symbols are as follows.

alpha: Slope factor beta: a photographic film, color paper, a constant determined by a combination of such printing lens DN: Mean concentration controller 52 controls over the roll photo film is a filter set position signal generated according to the amount of exposure E _i This is sent to the filter adjusting unit 40. The filter adjusting section 40 adjusts the insertion amount of the color correction films 36 to 38 into the optical path 41. After the adjustment of the filter, the shutter 59 is opened for a predetermined time, and the frame 18a is printed on the color paper 58 for exposure. Hereinafter, the same applies to the photo film 18 in the same manner.
Are sequentially printed and exposed.

Further, the recording control unit 65 controls the data recording unit 60 based on the upside-down direction data, the shooting date data, and the recording instruction data from the magnetic reading unit 46. Thereby, based on the recording instruction data, the photographing date is recorded on the print target frame of the color paper 58 at a position corresponding to the input area.
When the recording instruction data is back side printing, the shooting date is printed on the back side of the color paper 58.

In the case of the trimming print, similarly, the photographing date data and the recording instruction data are read out, and the photographing date data is recorded at a predetermined position in the screen of the color paper 58 or on the back side based on the data. At this time, the keyboard 52a connected to the controller 52 may be operated to manually input the recording position and the recording method to correct the recording position and the like.

Also, even when there is no recording instruction data, if necessary, the recording position and recording method are instructed by key input,
Thereby, the photographing date and the like may be printed or printed on the back surface.

In the above-described embodiment, the direction of the shooting date on the screen is specified using the upside-down direction data. Alternatively, the direction may be specified by manual input. In this case, the direction is switched according to the number of times of touching each input area 29 of the touch panel sensor 27.

In the above embodiment, the magnetic recording layer 18c is
, But may be formed over the entire surface of the film, in which case a transparent magnetic recording layer is used. In addition to magnetic recording, optical recording may be performed in a bar code format in a photosensitive emulsion layer area other than a frame. Further, an IC memory may be built in the patrone and recorded therein.

Further, in the above-described embodiment, the printing on the print photograph on the shooting date is recorded in the designated direction in the designated position on the screen by dot display using a panel in which the respective liquid crystal cells and light emitting elements are arranged in a matrix. However, it is also possible to use a numeric display to burn in other than this. In this case, the numeral display is moved in a two-dimensional direction on the color paper in order to imprint the photographing date at a desired position in the screen, and is rotated by 90 ° in order to change the direction.

In the above-described embodiment, the back side print designation switch 28 for printing data such as the photographing date on the back side is provided on the camera side. However, this may be omitted. In this case, it is preferable that the back side printing is performed on all the frames on the printer side.

In addition, the present invention can be practiced in a case where an image recorded by an electronic still camera is printed as a photograph. In this case, the electronic still camera writes, together with the image data, the data of the orientation of the main part, the shooting date data, and the recording instruction data thereof on a magnetic floppy disk. For example, when displaying an image on a CRT and recording the image on a color paper by a digital color printer, the data is read out, and the exposure amount control and the shooting date recording control based on the image data are performed.

〔The invention's effect〕

As described above, according to the present invention, date and time information of a shooting date or a shooting time, and recording instruction information for instructing which part of the print screen to record this date and time information or on the back side, Since the recorded image was recorded on the recording medium at a position different from that of the photographed image in accordance with the photographed image, the photographing date and time are recorded uniformly at a fixed position and orientation on the screen like the automatic date mechanism of a conventional camera. No longer
The recording position of the photographing date and time can be designated according to the print design or the like.

Further, when printing the shooting date and time in the screen, the shooting date and time can be recorded in accordance with the orientation of the screen by using the orientation information of the top and bottom of the screen.

Furthermore, in the case of trimming printing, the photographing date and time can be input at a designated position in the screen. In addition, the shooting date and time recorded on the screen is not enlarged and printed as it is compared to the one with the automatic date mechanism of the conventional camera, and the shooting date and time is recorded in the same size as other normal prints Can be.
