Fig. 2 A, Fig. 2 B are the illustrations that the expression user appreciates the scene of image.The user utilizes photograph print 22 to appreciate the situation (Fig. 2 B) in the majority of photographs according to such in the past.In addition, think that the chance that the user appreciates captured picture material in TV 21 fronts of large-scale picture increases (Fig. 2 A).Employed TV 21 is that the situation of high definition (HD) image quality is increasing, so the horizontal linear foot of TV 21 cun is than horizontal wide picture in the majority that is 16: 9.To this, as mentioned above, the horizontal linear foot of the imaging apparatus of camera is very little more more than the situation that is 4: 3 (photograph print 22 is also identical), so its deviation becomes problem.

Fig. 3 is the figure of the scene of the vertical composition photography of expression.Utilize the camera 1 of vertical composition to take subject 20.

Fig. 4 A-Fig. 4 C is the figure of the expression various images that to utilize horizontal linear foot cun more shown than the TV 21 of wide picture that is 16: 9.When taking the personage, use the camera of vertical composition shown in Figure 3 more, Fig. 4 A is the example that shows according to the captured image of this vertical composition.Shown in Fig. 4 A, when the picture reproduction that utilizes TV 21 with the photograph print is the still image of the lengthwise taken of prerequisite, about picture, produce big not display part 23a.

Owing to show 3: 4 image at 16: 9 pictures, so display part 23a is not bigger for this.In 16: 9 picture, with respect to length overall 16, the lateral length of actual displayed image has only 3 * 9/4=6.8, waste many.Even two vertical images are arranged in supposition side by side, because 6.8 * 2=13.6＜16 can not reach horizontal length overall.No matter under which kind of situation, all can not ignore the deterioration of efficient.Because seldom utilize big picture TV to watch, thus wish to utilize whole image to carry out moving strong demonstration, but in demonstration shown in Figure 4, should be to exist the impression of shortcoming stronger.

Therefore, in the present embodiment, for identical image, shown in Fig. 4 A → 4B → 4C, order shows the enlarged image that comprises face.The image of Fig. 4 B is a horizontal linear foot cun than being 5: 4, being that the center cuts the dimension modifying image that the original image of Fig. 4 A obtains with the upper part of the body.The image of Fig. 4 C be with TV 21 identical 16: 9 horizontal linear foot cun ratios, be that the dimension modifying image that the original image that cuts Fig. 4 A obtains is further amplified at the center with the face.In addition, this dimension modifying image can be when reproducing cut to handle to the original image that is write down and obtains, and also can write down this dimension modifying image with original image in advance when photography and use, and adopts which kind of mode can.By carrying out this demonstration, can realize that moving strong picture shows.

Fig. 5 A-Fig. 5 H is that expression is shown in the size of images on the picture of TV 21 and the figure of the relation of the pixel used in correspondence shows.Herein, the image of Fig. 5 A, Fig. 5 B, Fig. 5 C is respectively the image corresponding to each image of Fig. 4 A, Fig. 4 B, Fig. 4 C.And after Fig. 5 B and Fig. 5 B, frame of broken lines is represented former photographs, is the scope of general image that solid box represents to be presented at the scope of the dimension modifying image among the TV 21.

And Fig. 5 F-5H is the concept map of a part of the pixel map of presentation video data, and a zoning is represented a pixel, is to be illustrated in the figure of recovery time every the ratio of reading with extracting.Fig. 5 F～Fig. 5 H corresponds respectively to Fig. 5 A～Fig. 5 D.But below Shuo Ming the ratio of reading pixel only is example after all.

As the pixel count of the general image of still image, also want to bear this requirement based on photograph print, so the both full-pixel of more options imaging apparatus (for example 1,000 ten thousand pixels).On the other hand, TV 21 is not only horizontal linear foot cun ratio much smaller than imaging apparatus self, and the pixel count that can reproduce is also far fewer than imaging apparatus self.For example, in whole high definition TVs, be 1080 * 1820, for about 2,000,000 pixels, be considerably less, so the image of exporting to TV 21 from efferent 14 also is as long as less pixel count is promptly enough.Correspondingly transmitting time also shortens.For example, when output image was general image shown in Fig. 5 A, image processing part 5 cut pixel according to shown in Fig. 5 E with the represented pixel rate of oblique line (ratio of a pixel of per 8 pixels), carries out interpolation processing.That is, exporting the image that is reduced for necessary enough pixel counts according to the reproduction of TV 21 is efficiently.

Below, the image of Fig. 5 B is will upper part of the body part enlarged image from general image.When the such image of displayed map 5B, when the 5a of dimension modifying portion cuts prescribed limit from general image, consider that the amount of amplifying reduces at interval recovery rate and generates image.That is, because the increase of the display area in TV 21, so increase the ratio of the pixel of using when image pattern 4B shows like that in both full-pixel.For example shown in Fig. 5 F, adopt the ratio of 1 pixel to use herein, with per 4 pixels of general image data.This is because if the image that has extracted at interval significantly of above-mentioned Fig. 5 A is directly amplified, even then TV 21 seldom has high meticulous display capabilities or general image and has abundant information, also is merely able to reproduce coarse picture.

Fig. 5 C is further enlarged image.Fig. 5 C is illustrated in the facial parts zone of general image, and horizontal linear foot cun is than being very little than identical 16: 9 with the horizontal linear foot of TV 21.And, comparing with Fig. 5 B with above-mentioned Fig. 5 A, the 5a of dimension modifying portion has increased the pixel count that uses.For example shown in Fig. 5 G, utilize whole pixels of general image.Like this, change the ratio that extracts at interval, so can keep the high meticulous sense on the picture according to the size of images that cuts.

Wide picture TV with respect to 16: 9 more than is shown, the example of vertical composition that the viewing area is extremely different.In addition, Fig. 5 D shows the example of utilizing the captured image (4: 3) of normal laterally composition on TV 21.At this moment, because the such zone (16: 9) of solid line that can only displayed map 5D, so need carry out the demonstration of the such localized area of solid line.The such ratio of Fig. 5 H (per 4 pixels with 1 pixel) extract is adopted at the interval of this moment.According to the above, the reproduction that can make full use of TV 21 is appreciated beautiful high precise image.

Fig. 6 is that explanation generates the dimension modifying data and carries out the flow chart that image is exported the step of handling when reproducing.This image output is handled and is mainly carried out by the MPU 10 that defers to program, image processing part 5, the 5a of dimension modifying portion and efferent 14.

At first, the judgement image that will reproduce is dynamic image or still image (step S11).If dynamic image (step S11 "Yes") then carries out the output processing (step S21) that dynamic image shows usefulness.If be judged to be is still image (step S11 "No"), then reads static image data (step S12) by record-playback portion 7 from medium 8.Then, the photography composition of judging this image is vertically or laterally (step S13).Judgement in length and breadth is that the data in length and breadth that are attached in the view data during according to photography by detection unit 17 are in length and breadth judged.Perhaps, if there are not data in length and breadth, then also can when reproducing, judge according to the feature of image by image processing part 5.

The 5a of dimension modifying portion basis result of determination is in length and breadth carried out following dimension modifying processing, and efferent 14 is exported to TV 21 with this image.Above-mentioned processing is the processing that illustrates in above-mentioned Fig. 4 and Fig. 5 A-Fig. 5 H.At first, if not vertical composition (step S13 "No"), it promptly is normal laterally picture, then the 5a of dimension modifying portion is very little than cutting the zone that utilizes solid line to represent among Fig. 5 D according to the horizontal linear foot of the TV that is connected, and the image transitions that efferent 14 will change after the size is that the TV signal is exported (step S22).

The image of being exported is presented on the TV 21.In the explanation afterwards, be made as and export to horizontal linear foot cun than the TV that is 16: 9.And, about horizontal linear foot cun ratio, if sent horizontal linear foot cun than information then utilize this information from TV 21, if this information not, also could be according to user's appointment.

If the photo (step S13 "Yes") of vertical composition then repeats the demonstration of the image shown in Fig. 4 A → 4B → 4C successively with certain hour.This is for picture is sharply changed.Image processing part 5 after the view data of being read being changed in length and breadth direction, the general image shown in the output map 4A (step S14).Its horizontal linear foot is very little to remain 3: 4 than (horizontal stroke: vertical).After showing the stipulated time (step S15 "Yes"), switch to the image of Fig. 4 B illustrated dimension.The general image of the 5a of dimension modifying portion from being read than changing to 5: 4, detects horizontal linear foot cun information setting according to face and is equivalent to zone above the waist, cuts (finishing) this zone and also exports (step S16).Herein, 5: 4 horizontal linear foot cun than be by MPU 10 according to the horizontal linear foot of imaging apparatus 3 and TV 21 cun than automatic setting, and the notice dimension modifying 5a of portion.

In addition, after showing the stipulated time (step S17 "Yes"), switch to the image of Fig. 4 C illustrated dimension.The 5a of dimension modifying portion than changing to 16: 9, and detects horizontal linear foot cun information setting according to face and is equivalent to facial zone, and (finishing) this scope that cuts from general image is also exported (step S18).

In the demonstration of the such image of Fig. 4 C, if indication operation (step S19 "Yes"), the then end process of end are arranged.And,, then return step S11 if the indication (step S20 "Yes") of the demonstration that switches to other images is arranged.In addition, the DISPLAY ORDER during reproduction also can not be the order of Fig. 4 A → 4B → 4C, but the order of opposite Fig. 4 C → 4B → 4A.Herein, because the image file of dynamic image and still image is recorded in the medium of camera together, so according to the handover operation of user's image file, decision is dynamic image or still image, and switches display packing.And the image about cun ratio of the horizontal linear foot between 3: 4 and 16: 9 only shows 5: 4 image in above-mentioned flow chart, also can set more carefully in addition certainly.For example, also can set Three Estate halfway, that is, and 3: 4,4: 4,5: 4,6: 4,16: 9.

In addition, above-mentioned image output is handled and is carried out by the part outside the camera chain (camera lens 2, imaging apparatus 3, AFE portion 4) of camera 1.The device that is made of MPU 10, image processing part 5, the 5a of dimension modifying portion, facial test section 15, record-playback portion 7, efferent 14 etc. also constitutes the present invention.This device is called image output device.

In the above description, the situation that generates the dimension modifying image and output it to display unit when reproducing has been described.But be not limited thereto, also can when photography, generate and write down the dimension modifying image simultaneously.Below this situation will be described.

Fig. 7 is the flow chart that the step of the image recording processing that writes down the dimension modifying image when photography in the lump is described.This processing is main by execution such as the MPU 10 that defers to program, image processing part 5 and the 5a of dimension modifying portion.

Captured original image is stored in the temporary storage (not shown).And the original image of being stored is compressed to the both full-pixel that photograph print can bear or the image (step S31) of many pixels.Then, whether be that vertical composition changes processing according to this photographs.According to the judgement of detection unit 17 in length and breadth, judge whether be vertical composition (step S32).If not vertical composition (step S32 "No") but horizontal composition, then the original image before the compression of the 5a of dimension modifying portion from be stored in temporary storage generates the such horizontal wide dimension modifying image of solid line among Fig. 5 D, thereby record-playback portion 7 is recorded in (step S36) in the medium 8 with the dimension modifying image with original image.

On the other hand, if vertical composition (step S32 "Yes"), at first, the image of the whole subject of demonstration that record-playback portion 7 is such with Fig. 4 A, be that the above-mentioned original image that has compressed is recorded in (step S33) in the medium 8.Then, the 5a of dimension modifying portion is from former photographs generated the such change of Fig. 4 B horizontal linear foot cun intermediate image than (5: 4), record-playback portion 7 record these intermediate images (step S34).Horizontal linear foot cun ratio is determined according to the horizontal linear foot cun ratio of imaging apparatus 3 and TV 21 by MPU 10.In addition, the 5a of dimension modifying portion from above-mentioned photographs generate Fig. 4 C such effectively utilize whole TV picture, horizontal linear foot is cun than the image that is 16: 9, record-playback portion 7 writes down these images (step S35).

At this, write down the image of Three Estate so that divide Three Estate to switch demonstration, but also can carry out the record of two grades of step S33 and step S35.This is because the image of the grade of the less centre of being paid close attention to also can utilize electronic zoom to generate from the image of the 1st grade when reproducing.

As mentioned above, the time write down the dimension modifying image in photography yet, do not change the step that shows so need be when each the reproduction image of both full-pixel be carried out various sizes, reproducing side does not need special circuit.In addition, in above-mentioned example, divide Three Estate to represent size, but can certainly change to the above size of Three Estate.

Below, use Fig. 8,9 that the variation of above-mentioned the 1st execution mode is described.Shown in Fig. 4 A,, then feel the sense organ weak effect sometimes if the both sides of picture become the black display that does not have image fully.Therefore, in this variation, effectively utilize the example of staying white part when showing in reproduce showing display image.Fig. 8 is the flow chart of this synthetic step of handling of explanation.Fig. 9 is the figure that expression is shown in the image on the TV 21.

In this example, being created on the picture both sides has added the composograph of other images and has shown (Fig. 9).But preferred other additional images are the images that can not become the obstacle of viewing and admiring present image.That is, the image of more complicated or not intelligible image are not suitable for becoming these other additional images.For example, as other images, single the changing into or the abstract image that becomes the diagram style of image after preferably dwindling from captured image or with its part.Also the diagram image can be write down in advance in camera, used as other images.

According to the synthetic step of handling of flow chart simple declaration shown in Figure 8.Reading the captured original digital image data that is recorded in the medium 8 also decompresses.The 5a of dimension modifying portion carries out the dimension modifying of this original image and handles (step S41).Above-mentioned other images are recorded among medium 8 or the ROM 11, read image user's appointment or that select automatically and decompression from above-mentioned other images, as other images (step S42) that stay white region to use.Image processing part 5 is synthesized to this image in the original image that has carried out the dimension modifying processing, generates composograph, and compressed and decompressed 6a of still image compresses this composograph, and record-playback portion 7 is recorded in (step S43) in the medium 8 with composograph.Show indication if the user has, then read this composograph and be presented on the TV 21.By above processing, can effectively utilize wide picture more and effectively show.

(the 2nd execution mode)

Below, use Figure 10 A～Figure 12 that the 2nd execution mode is described.When the 2nd execution mode is a amplifier section when taking TV and reproduce, judges face-image and pay attention to the example of the photography of this part.Particularly in the portrait photo, general personage's face is important at the lengthwise image, so according to shown in Fig. 4 C facial parts being carried out macrophotography and demonstration is effective.In addition, the block diagram of using camera of the present invention is same as shown in Figure 1, so omit.And the horizontal linear foot of imaging apparatus and the predetermined TV 21 that shows is very little more identical than also, is respectively 4: 3,16: 9.

Figure 10 A, 10B are two examples that are presented at the monitoring picture on the display part 13 when vertically composition is photographed.The picture of Figure 10 A is to show that general image and expression wherein are exaggerated the picture of information in the zone of record.Display control unit 12 shows frame of broken lines 23b on picture top, be exaggerated the information in the zone of record as expression.The area part of frame 23b is exaggerated shown in Fig. 4 C.The horizontal linear foot of frame 23b cun ratio is ratios of 16: 9 corresponding to TV 21.

On the other hand, the picture of Figure 10 B is the example that many images show.The dimension modifying image 23d that uses during photographs (general image) 23c that many images demonstration still images are used on display part 13 and TV show.The horizontal linear foot of dimension modifying image 23d cun is than being 16: 9.Owing to show the image both sides that general image and size are changed simultaneously, institute is so that photography.At this moment, also the part of amplifying further can be shown as frame 23b when TV shows.Herein, the position of frame 23b also can be waited by user operable switch and be changed the position.In addition, more preferably, use face detection technique, the structure that when facial positions changes, can follow automatically for the position of once setting frame 23b once.

Figure 12 is the flow chart that the step of the photograph processing of having used above-mentioned monitoring picture is described.Situation when illustrating that for understanding is main easily vertical composition is photographed herein.This processing is mainly carried out by the MPU 10 that defers to program, the 5a of dimension modifying portion and display control unit 12.

At first, on display part 13, show general image (step S51).This is to press shutter chance and composition in order to judge.Also show the frame 23b (step S52) of information that is used for the zone of the dimension modifying picture that on the TV picture, shows as expression.That is the such image of displayed map 10A.Certainly, also can be that the such many images of Figure 10 B show.

Wait for user's photography indication (step S53).Being judged as is the suitable timing and the user of composition, operation shutter release switch (for example switch 16a).When the operation indication (step S53 "Yes"), be equivalent to the still image photography (step S54) of whole image (general image).Then, carry out photography (step S55) in step S52 utilizes the zone that frame 23b represents.In the photography of step S55, record changes to the image of the size of the reproduction that is fit to TV 21 by the 5a of dimension modifying portion.Thus, when having used TV 21, can switch the picture shown in the picture shown in Fig. 4 A and Fig. 4 C, perhaps automatically conversion is appreciated.
