Can be set (for example, FIG. 8 to FIG. 10).

  When the enlargement range is set including the center of the correction direction of the target image, the adjustment unit can prohibit the setting of the enlargement region to the region between the person images (for example, FIG. 10).

  The adjustment means can prohibit the setting of the enlarged area to the area between the person images when the interval between the person images is more than a predetermined distance (for example, FIG. 10).

  FIG. 1 is a block diagram illustrating a hardware configuration example of a printer 1 to which the present invention is applied. The printer 1 is a color inkjet printer that supports so-called direct printing, in which an image is printed based on image data acquired from a memory card 18 or the like. Note that the present invention can be applied not only to color printing but also to monochrome printing.

  The printer 1 includes a CPU 11, an internal memory 12, an operation unit 13, a display unit 14, a printer engine 15, and a card interface (I / F) 16.

  A CPU (central processing unit) 11 controls each unit and executes various processes according to a program stored in the internal memory 12.

  For example, the CPU 11 compresses a compression area of an image to be corrected (hereinafter also referred to as a target image TI) in a predetermined direction, and corrects the expansion area of the target image TI in a predetermined direction (hereinafter referred to as slim). (Also referred to as correction). Details of the processing for executing the slim correction (hereinafter also referred to as slim correction control processing) will be described later.

  The internal memory 12 includes a ROM (Read Only Memory) that stores various programs executed by the CPU 11 and various data, and a RAM (Random Access Memory) that temporarily stores programs and data to be executed by the CPU 11. It is configured.

  The operation unit 13 includes one or a plurality of buttons and a touch panel, and notifies the CPU 11 of the operation content by the user.

  The display unit 14 includes a liquid crystal display and displays an image corresponding to the display data supplied from the CPU 11.

  The printer engine 15 is a printing mechanism that performs printing based on the print data supplied from the CPU 11.

  The card interface (I / F) 16 is an interface for exchanging data with the memory card 18 inserted in the card slot 17. In this example, image data as RGB data is stored in the memory card 18, and the printer 1 acquires the image data stored in the memory card 18 via the card interface 16.

  The components of the printer 1 are connected to each other via a bus 19.

  The printer 1 may further include an interface for performing data communication with other devices (for example, a digital still camera).

  FIG. 2 is a block diagram illustrating a functional configuration example of the printer 1 for executing the slim correction control process. This function can be realized by the CPU 11 executing a predetermined program stored in the internal memory 12.

  The face image detection unit 21 analyzes a target image TI that is a target of correction processing, for example, read from the memory card 18 and input to the printer 1, and estimates that a human face portion of the target image TI is captured. An area including an image to be processed (hereinafter referred to as a face image FA) is detected.

  The person image detection unit 22 includes an area (hereinafter referred to as a person image FB) that includes an image that is estimated to include the entire face, body, legs, and the like of the person based on the size or position of the face image FA. Is detected. In this example, the area including the face image FA is the person image FB, but the area not including the face image FA may be the person image FB. The person image FB is detected based on the face image FA, but the detection of the person image FB is not limited to this.

  The adjustment unit 23 adjusts the range of the compression area and the enlargement area set in the target image TI so that the person image FB is not included in the enlargement area.

  FIG. 3 is a diagram illustrating an example of the compressed region and the enlarged region in the initial state. In this example, as an initial state, both ends of the target image TI are set to the enlarged region Ra, and the central portion is set to the compressed region Rb. When the person image FB is included in the enlarged region Ra, the adjustment unit 23 performs adjustment such as narrowing the range of the enlarged region Ra so that the person image FB is not included in the enlarged image Ra.

  Returning to FIG. 2, the slim correction unit 24 performs slim correction. That is, in order to compress the compression region Rb in the horizontal direction on the image (X-axis direction in the example of FIG. 3) at a predetermined compression rate and maintain the image size, the enlargement rate according to the compression rate is Correction for enlarging the enlargement area Ra is performed. Note that the direction to be compressed or expanded (in the example of FIG. 3, the direction of the X axis) is simply referred to as a correction direction when it is not necessary to distinguish each direction.

  The output control unit 25 executes a process of generating display data or print data from the image data of the target image TI that has been subjected to the correction process. The display data is supplied to the display unit 14 and displayed. The print data is supplied to the printer engine 15 and an image is printed based on the print data.

  FIG. 4 is a flowchart showing a flow of slim correction control processing by the printer 1. The slim correction process will be described with reference to this flowchart.

  In step S <b> 1, the face image detection unit 21 detects a face image FA in the target image TI that is a target of slim correction processing.

  The detection of the face image FA is a known detection method such as a pattern matching method using a template representing a basic shape such as a person's eyes, nose, and mouth (see, for example, JP-A-2006-279460). Can be used.

  In this face image detection process, face area data composed of the position and size of the face image FA (vertical and horizontal size of the rectangular pixel area with the face position as a base point), and a composition posture such as face upright or inverted are expressed as face angles. Face posture data is acquired as face information.

  Next, in step S2, the person image detection unit 22 detects an area including a person's face, body, and legs in the target image TI as a person image FB. Specifically, since the detected face image FA is accompanied by data on its size and composition posture, the average head-to-body ratio is used as a reference from the face size and face posture in the target image TI. The size of the torso and legs located below the face is estimated, and the person area FB corresponding to the face image FA is detected.

  FIG. 5 is a diagram illustrating a detection example of the person image FB. In FIG. 5, a person image is schematically shown, and a face image FA and a person image FB of the person image are surrounded by dotted lines.

  Returning to FIG. 4, in step S <b> 3, the adjustment unit 23 determines whether or not the person image FB is included in the enlarged region Ra. If it is determined that the person image FB is included, the process proceeds to step S <b> 4.

  6 to 10 are diagrams showing the positional relationship between the person image FB and the enlarged region Ra. 6 to 10, the dotted frame indicating the range of the person image FB shown in FIG. 5 is omitted. In the upper example of FIG. 6, there is one person image FB, and a part of the person image FB is included in the left enlarged region Ra. In the example on the upper side of FIG. 7, there is one person image FB, and the entire person image FB is included in the enlarged region Ra on the left side.

  In the uppermost example of FIG. 8, there are two person images FB, and the entire left person image FB is included in the left enlarged area Ra. In the example at the top of FIG. 9, there are three person images FB, and the rightmost person image FB is all included in the right enlarged region Ra. In the uppermost example of FIG. 10, there are two person images FB, all of the left person images FB are in the left enlarged area Ra, and all of the right person images FB are in the right enlarged area Ra. include.

  If the person image FB is included in the enlarged region Ra as shown in the upper side or uppermost row of FIGS. 6 to 10, the process proceeds to step S4.

  In step S4, the adjusting unit 23 adjusts the ranges of the enlarged region Ra and the compressed region Rb so that the person image FB is not included in the enlarged region Ra. Thereafter, in step S5, the slim correction unit 24 compresses the determined compression region Rb in the correction direction at a predetermined compression rate, and expands the expansion region Ra at an expansion rate corresponding to the compression rate.

  When it is determined in step S3 that the person image FB is not included in the enlarged region Ra (for example, FIG. 5), the slim correction unit 24 performs compression in the initially set enlarged region Ra and compression region Rb in step S5. The area Rb is compressed in the correction direction at a predetermined compression rate, and the enlarged area Ra is enlarged at an enlargement ratio corresponding to the compression ratio.

  The region adjustment processing in step S4 will be specifically described with reference to FIGS.

  For example, when the person image FB is included in the enlarged region Ra as shown in the upper side of FIG. 6, the range of the enlarged region Ra is the right end of the enlarged region in the X-axis direction as shown in the lower side of FIG. Is narrowed to the left end of the person image FB. Then, the range of the enlarged region Ra on the right side that does not include the person image FB is widened by the narrowed amount. The range of the compression region Rb is changed along with the change of the range of the enlarged region Ra.

  As shown in the upper side of FIG. 7, when the person image FB is included in the enlarged region Ra, that is, from the end of the person image FB (the left end in the example of FIG. 7) to the end of the target image TI (in the example of FIG. When the distance to the left end is equal to or less than the threshold value XL, the left enlarged region Ra including the person image FB is deleted as shown in the lower side of FIG. 7 (that is, the range of the enlarged region Ra is the X axis). The right end of the enlarged region Ra in the direction is narrowed to the left end of the target image TI). Then, the range of the enlarged region Ra on the right side that does not include the person image FB is expanded by the amount deleted. The range of the compression region Rb is changed along with the change of the range of the enlarged region Ra.

  In the example of FIG. 6, since the distance from the left end of the person image FB to the left end of the target image TI is larger than the threshold value XL, the range of the enlarged area Ra is narrowed by the area including the person image FB.

  When the person image FB is included in the enlarged region Ra as shown in the uppermost part of FIG. 8, the distance from the left end of the left person image FB to the left end of the target image TI is equal to or less than the threshold value XL. As shown in the second row from the top in FIG. In the case of this example, when the range of the right enlarged region Ra that does not include the person image FB is expanded by the amount deleted as shown in the second row from the top in FIG. 8, the expanded right enlarged region Ra becomes the right side. The person image FB is included. Therefore, in such a case, as shown in the third row from the top in FIG. 8, the left enlarged region Ra is deleted, but the right enlarged region Ra is not expanded. The range of the compression area Rb is changed as much as the left-side enlarged area Ra is deleted.

  When the person image FB is included in the enlarged region Ra as shown in the uppermost part of FIG. 9, the distance from the left end of the right person image FB to the right end of the target image TI is equal to or less than the threshold value XL. The right-side enlarged region Ra including is shown in the second row from the top in FIG. Also in this case, if the left enlarged region Ra that does not include the person image FB is expanded by the amount deleted, the expanded left enlarged region Ra includes the left person image FB. As shown in the third row, the right enlarged region Ra is deleted, but the left enlarged region Ra cannot be expanded. The range of the compression area Rb is changed as the right-side enlarged area Ra is deleted.

  When the person image FB is included in the enlargement area Ra as shown in the uppermost part of FIG. 10, the distance from the left end of the left person image FB to the left end of the target image TI is equal to or less than the threshold value XL, so The area Ra is deleted as shown second from the top in FIG. In this case, since the person image FB is already included in the right-side enlarged region Ra, if the range of the right-side enlarged region Ra is expanded by the amount deleted as shown in the second row from the top of FIG. Naturally, the right-side person image FB is included in the enlarged right-side enlarged area Ra.

  Since the distance from the right end of the right person image FB to the right end of the target image TI is equal to or smaller than the threshold value XL, the right enlarged region Ra is deleted. Also in this case, since the person image FB is already included in the left enlarged region Ra, if the left enlarged region Ra is expanded by the amount of deletion, the enlarged left enlarged region Ra has a left side. A person image FB is included.

  That is, in this case, as shown in the third row from the top in FIG. 10, both the left and right enlarged areas Ra are deleted, and the enlarged area Ra is not provided. In this case, the compression region Rb is not provided, and slim correction is not performed (the process of step S5 is skipped).

  As described above, when the person image FB is included in the enlarged area Ra, the range of the enlarged area Ra and the compression area Rb is adjusted so that the person image FB is not included in the enlarged area Ra, and slim correction is performed. Since this is done, the person image FB can be prevented from being enlarged in the horizontal direction.

[Adjustment method of other enlarged region Ra and compression region Rb]
As shown in FIGS. 8 to 10, when the person image FB is included by expanding the range of the other enlarged region Ra by the size of the narrowed enlarged region Ra, the enlarged region Ra is enlarged. I wasn't. Therefore, when the enlargement area Ra cannot be enlarged in this way, a new enlargement area Ra can be provided in an area where the person image FB does not exist, instead of enlarging the enlargement area Ra.

  For example, in the example of FIGS. 8 to 10, as shown in the fourth row from the top of FIGS. 8 to 10, an enlarged area Ra having a size corresponding to the deleted size is provided in the area between the person images FB. .

  If the enlarged region Ra is provided in this way, the compression rate can be increased compared to the case of the third stage from the top of FIGS.

[Adjustment method of other enlarged region Ra and compression region Rb]
For example, when taking a commemorative photo with a certain copper image in between, it is conceivable that an image of a main subject (in this case, a copper image) exists between the person images FB. Therefore, when a new enlarged area Ra is provided between the person images FB, the enlarged area Ra is set when the distance between the person images FB is a certain distance or more, including the center of the correction direction of the target image TI. In such a case, it is possible not to set the enlarged region Ra.

  For example, in the case of the example in FIG. 10, since the distance between the person images FB is long, the enlarged region Ra can be set not to be set. In the case of the example in FIG. 10, the enlarged region Ra is set including the center of the correction direction of the target image TI, so that the enlarged region Ra cannot be set.

[Adjustment method of other enlarged region Ra and compression region Rb]
In the above description, the range of the enlarged region Ra and the compressed region Rb has been adjusted based on the position of the person image FB, but the range to be adjusted by the user can also be set. For example, the user can change the range of the enlargement range Ra and the compression region Rb with the pointer device.

[Other slim correction control processing]
Further, for example, when a person image FB of a lying person and a person image FB of a standing person are mixed, the range of the enlarged region Ra and the compressed region Rb is determined depending on whether or not it is included in the enlarged region Ra, and slim If correction is performed, correction may not be performed properly. Therefore, in such a case, it is possible to prevent slim correction. The person image FB of the person lying down can be determined based on, for example, face posture data accompanying the face image FA.

[Other embodiments]
In the above description, the ink jet printer 1 has been described as an example. However, the present invention can be applied to a printer other than the ink jet method, and can be applied to a digital camera or a photo viewer as long as the image is presented to the user. it can.
