A character reading head 46 is arranged in front of the print position, and reads the character image 19 recorded on each frame when the photographic film 18 is fed to the print position.

This reading signal is sent to a decoder 47, which reads the characters based on the signal from the character reading head 46, and sends this code signal to the mode selector 48. The mode selector 48 searches the memory 49 based on the code signal, and sends the correction coefficient for the exposure amount for the corresponding drawing mode to the calculation unit 50, and sends the control amount for the printing magnification in the trimming mode to the controller 50.
Send to 1. The memory 49 stores information in advance for each drawing mode.
A correction coefficient for exposure amount and a control amount for controlling zooming of the printing lens are stored.

Further, diagonally above the printing position, a scanner 55 is provided which is composed of a lens 53 and an image area sensor 54.
is placed at the printing position, and the transmitted light at each point of the frame set at the printing position is measured.

The signal from this scanner 55 is sent to a signal processing circuit 57, where it is logarithmically converted and digitally converted.
The density signal at each point is sent to the calculation section 50. The controller 51 adjusts the set positions of the color correction filters 36 to 38 according to the printing exposure amounts of the three colors calculated by the calculation unit 50. Further, the controller 51 controls various parts such as the shutter drive part 58 in addition to the filter adjustment part 40.

A printing lens 60 is disposed above the printing position, and enlarges and projects the image of the set frame onto color paper 62 disposed behind a paper mask 61.

A zoom lens is used as the printing lens 60, and the focal length is adjusted by a lens driving section 63 so that a predetermined printing magnification is achieved during trimming. In addition, the baked lens 60
A shutter drive unit 58 is provided between the color paper 62 and the color paper 62.
A shutter 65 whose opening and closing are controlled by is arranged.

Next, the operation of the above embodiment will be explained. When taking a photograph, if the user wishes to specifically record the drawing intention, the touch panel sensor 20 is used to input a character image indicating the drawing intention. This input is performed by writing a character image on the surface of the touch panel sensor 20. The input character image indicating the drawing intention is displayed on the liquid crystal display panel 22 by the driver 21.

Next, when you point the camera at the subject, decide on the composition, and press down on the release button, the control mechanism 15 activates the drive pin 1.

is recorded in the surrounding area of the corresponding frame. Note that the recording of the drawing intention may be performed after the image is possessed. In this case, a drawing intention recording mode is prepared and this mode is designated before shooting. When this mode is specified, the film is not advanced frame by frame after shooting. Then, input the drawing intention.
When recording, the film advances frame by frame.

When one day's worth of photographic film has been photographed, the photographic film 18 is taken out from the camera and submitted to a photo processing laboratory. At the photo development laboratory, the photographic film 18 is developed to convert each frame recorded as a latent image and a character image indicating the intention of the image into a visible image.

The developed photographic film 18 is loaded into a film carrier 43 of a photographic printer shown in FIG. The film carrier 43 sets the frame to be printed, for example 18A, at the print position.

When this frame 18A is transported toward the print position, a character image 19 indicating the drawing intention is read by the character reading head 46, and this signal is converted by the decoder 47 into a code signal of the drawing mode.

The mode selector 48 selects the memory 49 based on the code signal.
is searched, and the exposure amount correction coefficient corresponding to the code signal and the print magnification control ml at the time of trimming are sent to the calculation unit 50 or controller 51.

When the frame 18A is set at the print position, the scanner 55 measures red, green, and blue transmitted light at each point of the frame 18A. The photometric values of these three colors are converted into densities by the signal processing circuit 57 and then sent to the calculation section 50. In the calculation unit 50, the printing exposure amount E, (i

Specifically, in the "landscape spring mode", the correction coefficient emphasizes green more than usual. Furthermore, in the "landscape mode", red is emphasized more than usual, and in "landscape snow mode", white is emphasized more than usual. In addition, in the ``person back finishing mode'', a method is used that emphasizes the skin color of the person with sunburn more than the normal color. In addition, the "person mode" uses a mode that emphasizes skin tones. In addition to the above-described drawing mode, various drawing modes may be prepared, and in this case as well, correction coefficients specific to this drawing mode are set in advance through experiments or the like.

For example, if you want to photograph a person as a shadow, make the person look a little darker, make the sun look like a rising or setting sun, see the moon in the sky, or emphasize autumn leaves, set each of these modes.

Furthermore, in the case of the frame 18A in which "trimming mode" is recorded as the drawing mode, the printing magnification adjustment amount of the printing lens 60 and the corresponding correction coefficient are stored in the memory 49.
is determined, and the printing exposure amount E is calculated accordingly.

The controller 51 generates a filter set position signal according to the printing exposure amount E, and sends this to the filter adjustment section 40. This filter adjustment section 40 includes a color correction filter 36
-38 is adjusted in the amount of insertion into the optical path 41. Further, the lens driving section 63 is controlled according to the amount of adjustment of the burning magnification, and the burning magnification of the burning lens 60 is changed to a desired burning magnification. After adjusting the filter and changing the printing magnification, the shutter 65 is opened for a certain period of time, and the frame 18A is printed and exposed on the color paper 62. Hereafter, in the same manner, each frame 1 of the photo filter 18 is
8A is sequentially printed and exposed.

In the case of the above embodiment, kanji are manually written to indicate the drawing intention, but katakana or hiragana may also be used to make the structure of the character reading rad 46 and decoder 47 simple. good. Furthermore, the drawing mode may be symbolized by alphanumeric characters, etc., and the alphanumeric characters may be used. In addition to the character image 19, a bar code or the like may be used as the drawing intention information recorded on the photographic film in one day.

In the above embodiment, the touch panel sensor 20 is used to input drawing intention information, but instead of this, a matrix of push button switches corresponding to the number of elements is used to input character images. You can also. Furthermore, instead of inputting a character image, a plurality of switches may be provided, and the drawing intention may be encoded and input using a combination of the switches.

Further, instead of recording the drawing intention information on the photographic film 18, it may be recorded on an IC card or a magnetic recording section formed on the outer periphery of the cartridge, or it may be recorded on a recording medium connected to the photographic film. .

Furthermore, the present invention can also be used when printing images recorded with an electronic still camera. In this electronic still camera, drawing intention information is written onto a magnetic floppy along with image data. And for example CR
When an image is displayed on the T and recorded on color paper by a digital color printer, the drawing information is read out and used to control the exposure amount of each point based on the image data.

[Effects of the Invention] As explained above, according to the present invention, information on the intention of drawing is recorded on a photographic film when taking a photograph, and is used for calculating the exposure amount when printing a photograph, changing the printing magnification, etc. Therefore, photographic prints can be efficiently produced without the need for negative inspection or the like. Moreover, it automatically reads the drawing intent and controls the exposure amount etc. based on this.
Compared to systems that perform arithmetic processing on photometric values at each point on the screen to determine the scene, the photographer's intentions can be more accurately reflected in the photo print.
