Description
本発明は、半導体集積回路に関し、特に、撮影した写真画像を表示制御する技術に関する。
The present invention relates to a semiconductor integrated circuit, and more particularly to a technique for controlling display of a photographed photographic image.
近年、デジタルスチルカメラ（以降、ＤＳＣと称する）が急速に普及している。ＤＳＣでは、ＳＤ（Secure Digital）メモリカードに代表される書き換え可能な記録カードメディアに写真画像を圧縮して記録する方式が採用されている。これにより、大量に撮影した後に写りの良い写真画像を選択して印刷したり、写りの悪い写真画像を削除したりすることが容易となる。また、記録カードメディアの大容量化、低価格化が急速に進むとともに、信号処理が高速化しているため高速な連写機能の利用が可能となっている。そのため、「大量に撮影して後から選ぶ」という使い方が多くのユーザーによってなされている。
In recent years, digital still cameras (hereinafter referred to as DSCs) are rapidly spreading. In DSC, a method of compressing and recording a photographic image on a rewritable recording card medium represented by an SD (Secure Digital) memory card is employed. This makes it easy to select and print a photo image with good image quality after deleting a large number of images, or to delete a photo image with poor image quality. In addition, the capacity and cost of recording card media are rapidly increasing, and since signal processing is accelerated, a high-speed continuous shooting function can be used. For this reason, many users have used the method of “photographing a large number and selecting later”.
このような使い方によって、シャッターチャンスを待って撮影したり、撮影後に写りを確認し写りの悪い場合にはその写真画像を削除して再度撮影し直すといった手間が不要となる。その半面、連写機能などで撮影した大量の写真画像から写りの良い写真画像を選択して印刷したり、写りの悪い写真画像を選択して削除するといった撮影後の作業が非常に煩雑になってしまう。
This way, there is no need to take a picture after waiting for a photo opportunity, or to check the picture after taking a picture and delete the picture and take it again if the picture is not good. On the other hand, post-shooting operations such as selecting and printing good-looking photo images from a large number of photo images taken with the continuous shooting function, etc., and deleting them by selecting poor-looking photo images become very complicated. End up.
そこで、大量の写真画像から同一である可能性が高いものを自動的に絞り込んで検出して、検出された写真画像を一覧表示するようにしている（例えば、特許文献１参照）。
Therefore, a large number of photographic images that are highly likely to be the same are automatically narrowed down and detected, and the detected photographic images are displayed in a list (for example, see Patent Document 1).
検出した同一の写真画像の枚数が多くなると、ユーザは写りの良い写真画像を選択するために多くの画像を比較しなければならない。そのため、非常に多くの時間を要することになり、写真画像の選別作業が困難となってしまう。
When the number of identical photo images detected increases, the user must compare many images in order to select a good photo image. For this reason, a very long time is required, and it becomes difficult to select a photographic image.
本発明は、かかる点に鑑みてなされたものであり、撮影後の選別作業が容易になるように写真画像を表示することを課題とする。
The present invention has been made in view of such a point, and an object of the present invention is to display a photographic image so that a sorting operation after photographing is facilitated.
上述した課題を解決するため本発明によって次のような解決手段を講じた。すなわち、撮影された静止画像の表示制御をする半導体集積回路として、撮影された静止画像のうち同一シーンに係る静止画像を検出する同一シーン検出部と、検出された静止画像の相互間で写りが異なる領域を検出する差異領域検出部と、検出された領域を強調する表示制御を行う制御部とを備えているものとする。
In order to solve the above-mentioned problems, the present invention has taken the following solutions. In other words, as a semiconductor integrated circuit that controls display of a captured still image, the same scene detection unit that detects a still image related to the same scene among the captured still images and the detected still image are reflected between each other. It is assumed that a different area detection unit that detects different areas and a control unit that performs display control to emphasize the detected areas are provided.
これによると、撮影された静止画像のうち同一シーンに係る静止画像において写りが異なる領域が強調して表示される。
According to this, among the captured still images, the regions with different reflections in the still images related to the same scene are highlighted and displayed.
あるいは、撮影された静止画像の表示制御をする半導体集積回路として、撮影された静止画像のうち同一シーンに係る静止画像を検出する同一シーン検出部と、検出された静止画像を写りが似通っているものどうしでグループ化し、各グループから代表画像を選定するグループ構成部と、代表画像の表示制御を行う制御部とを備えているものとする。
Alternatively, as a semiconductor integrated circuit that controls display of a captured still image, the same scene detection unit that detects a still image related to the same scene among the captured still images is similar to the captured still image. It is assumed that a group configuration unit for grouping objects and selecting a representative image from each group and a control unit for controlling display of the representative image are provided.
これによると、撮影された静止画像のうち同一シーンに係る静止画像の似通ったものどうしがグループ化されて各グループの代表画像が表示される。すなわち、選別作業のために表示される静止画像の枚数が減少する。
According to this, among the photographed still images, similar ones of the still images related to the same scene are grouped and a representative image of each group is displayed. That is, the number of still images displayed for the sorting operation is reduced.
本発明によると、ユーザによる撮影後の静止画像の選別作業が容易となる。
According to the present invention, the user can easily select a still image after shooting.
以下、本発明を実施するための形態について、図面を参照しながら説明する。図１は、本発明の一実施形態に係る静止画像表示制御装置の構成を示すブロック図である。記録メディア１は、例えばＳＤメモリカード等である。記録メディア１には、ＤＳＣ等で撮影された複数の画像が記録されている。この記録メディア１の画像は読込部２で読み込まれ、半導体集積回路１０で表示制御されて表示部１９に表示される。
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a still image display control apparatus according to an embodiment of the present invention. The recording medium 1 is, for example, an SD memory card. A plurality of images photographed by DSC or the like are recorded on the recording medium 1. The image on the recording medium 1 is read by the reading unit 2, is display-controlled by the semiconductor integrated circuit 10 and is displayed on the display unit 19.
入力部２２には、ユーザの操作が入力される。消去部２３は、ユーザの削除操作を受けた画像を記録メディア１から削除する。なお、消去部２３は、ユーザーが選択した写りの良い画像以外の画像を自動的に削除してもよい。
The user operation is input to the input unit 22. The erasing unit 23 deletes the image that has been subjected to the user's deletion operation from the recording medium 1. Note that the erasing unit 23 may automatically delete an image other than a good image selected by the user.
同一シーン検出部１１は、読込部２で読み込まれた画像のうち例えば０．５秒以下の撮影間隔で連写された画像を同一シーンであると判断して検出する。
The same scene detection unit 11 determines that images continuously taken at a shooting interval of, for example, 0.5 seconds or less among the images read by the reading unit 2 are the same scene.
グループ構成部１２は、同一シーン検出部１１で検出された画像のうちいずれか２枚の画像間の動きベクトルを検出して２枚の画像の被写体の動き量を算出する。グループ構成部１２は、この動き量に基づいて２枚の画像の被写体の位置を合わせてから、これら２枚の画像をそれぞれ例えば１６×１６画素の領域に分割し、２枚の画像どうしで対応する領域毎に画素値差分を累計する。なお、画素値差分が負値となる場合もあるため、その２乗和あるいは絶対値を累計する。そして、各領域の累計値が所定値よりも小さい場合に、これら２枚の画像を写りが類似する画像と判断してグループ化する。そして、グループ構成部１２は、例えば各グループ内の画像のそれぞれについて空間周波数分析を行い、高周波成分を多く含む画像を代表画像として選定する。
The group configuration unit 12 detects a motion vector between any two images among the images detected by the same scene detection unit 11, and calculates the motion amount of the subject of the two images. The group construction unit 12 aligns the positions of the subjects of the two images based on the amount of movement, and then divides each of the two images into, for example, an area of 16 × 16 pixels, so that the two images correspond to each other. The pixel value difference is accumulated for each area to be processed. Since the pixel value difference may be a negative value, the sum of squares or absolute values thereof are accumulated. Then, when the cumulative value of each region is smaller than a predetermined value, these two images are judged to be similar images and are grouped. And the group structure part 12 performs a spatial frequency analysis about each of the image in each group, for example, and selects the image containing many high frequency components as a representative image.
差異領域検出部１３は、代表画像のうちいずれか２枚の画像について、グループ構成部１２と同様に画素値差分を累計する。そして、各領域のうち累計値が所定値よりも大きい領域を写りが異なる領域であると判断して検出する。
The different area detection unit 13 accumulates pixel value differences for any two images among the representative images in the same manner as the group configuration unit 12. Then, an area where the cumulative value is larger than the predetermined value among the areas is determined to be an area with different reflection and is detected.
制御部１４は、差異領域検出部１３で検出された写りが異なる領域を例えば点線枠で囲む等して表示制御を行う。表示部１９は、制御部１４で表示制御された画像を表示する。
The control unit 14 performs display control by, for example, enclosing regions with different reflections detected by the different region detection unit 13 with, for example, a dotted frame. The display unit 19 displays the image whose display is controlled by the control unit 14.
次に、静止画像表示制御装置の動作例を説明する。まず、撮影された複数の画像から図２に示すように、例えば撮影間隔が０．５秒以下のものが１０枚存在する場合には、その１０枚の画像１～１０が同一シーンとして検出される。画像１～１０が検出されると、それらのうち画像１～４がグループ１、画像５～６がグループ２、画像７～１０がグループ３としてそれぞれグループ化される。そして、画像１、画像５、画像９がそれぞれグループ１～３の代表画像として選定される。
Next, an operation example of the still image display control device will be described. First, as shown in FIG. 2, for example, when there are 10 images with a shooting interval of 0.5 seconds or less from a plurality of captured images, the 10 images 1 to 10 are detected as the same scene. The When the images 1 to 10 are detected, the images 1 to 4 are grouped as the group 1, the images 5 to 6 are grouped as the group 2, and the images 7 to 10 are grouped as the group 3, respectively. Then, image 1, image 5, and image 9 are selected as representative images of groups 1 to 3, respectively.
その後、図３に示すようにグループ１～３の代表画像間で相互に写りが異なる領域が検出され、それらの領域がそれぞれ点線枠３０，３１で強調されて表示部１９に表示される。
After that, as shown in FIG. 3, areas that are different from each other in the representative images of the groups 1 to 3 are detected, and these areas are highlighted on the dotted line frames 30 and 31 and displayed on the display unit 19.
以上のように、ユーザは表示された画像の点線枠で囲まれた領域を比較することで写りの良し悪しを容易に判断して写りの良い画像を選択することができる。また、同一シーンに係る画像が多くても、グループ化して代表画像を表示することで写りの良し悪しを比較する画像の枚数が減少するため、写りの良い画像を選択する時間を短縮することができる。
As described above, the user can easily determine the quality of the image by comparing the areas surrounded by the dotted frame of the displayed image, and can select an image with a good image. In addition, even if there are many images related to the same scene, the number of images for comparing the quality of the images is reduced by grouping and displaying the representative images, so that the time for selecting images with good images can be shortened. it can.
なお、同一シーン検出部１１は、読込部２で読み込まれた画像のうちいずれか２枚の画像について、グループ構成部１２と同様に画素値差分を累計し、各領域の累計値が所定値よりも小さい場合に２枚の画像を同一シーンであると判断してもよい。また、同一シーン検出部１１、グループ構成部１２および差異領域検出部１３において、通常は画像の有意な領域は画像の中央に存在しているので、画像の中央の領域について画素値差分を累計してもよい。また、人物の顔検出処理により顔部分を検出し、顔部分の領域の画素値差分を累計してもよい。
The same scene detection unit 11 accumulates pixel value differences for any two images read by the reading unit 2 in the same manner as the group configuration unit 12, and the accumulated value of each region is greater than a predetermined value. May be determined to be the same scene. Further, in the same scene detection unit 11, the group configuration unit 12, and the different region detection unit 13, since a significant region of the image normally exists at the center of the image, the pixel value difference is accumulated for the central region of the image. May be. Further, a face part may be detected by a human face detection process, and pixel value differences in the face part region may be accumulated.
また、制御部１４は、ユーザが例えば点線枠３０を選択した場合に、図４に示すように点線枠３０の領域を表示部１９に拡大して表示する制御を行ってもよい。また、制御部１４は、ユーザが例えばグループ１を選択した場合に、図５に示すように選択されたグループ１内の画像１～４を表示部１９に並べて表示する制御を行ってもよい。
Further, when the user selects the dotted line frame 30, for example, the control unit 14 may perform control to enlarge and display the area of the dotted line frame 30 on the display unit 19 as shown in FIG. Further, when the user selects, for example, group 1, the control unit 14 may perform control to display the images 1 to 4 in the selected group 1 side by side on the display unit 19 as shown in FIG.
また、グループ構成部１２を省略してもよい。この場合、差異領域検出部１３は、同一シーンに係る画像どうしで写りが異なる領域を検出する。あるいは、差異領域検出部１３を省略してもよい。この場合、各グループの代表画像は、図６に示すように表示される。
Further, the group configuration unit 12 may be omitted. In this case, the different area detection unit 13 detects areas in which the images related to the same scene are different from each other. Alternatively, the different area detection unit 13 may be omitted. In this case, the representative image of each group is displayed as shown in FIG.
また、複数のシーンが存在する場合には、ユーザが入力部２２で選択したシーンに対してグループ構成部１２や差異領域検出部１３で処理するようにすればよい。
In addition, when there are a plurality of scenes, the group composition unit 12 or the different area detection unit 13 may process the scene selected by the user using the input unit 22.
本発明に係る半導体集積回路は、同一シーンの画像の選別作業を容易にすることができるため、連写等で大量に同一シーンの画像の撮影が可能なデジタルスチルカメラ等に有用である。
Since the semiconductor integrated circuit according to the present invention can easily select images of the same scene, it is useful for a digital still camera or the like that can shoot a large number of images of the same scene by continuous shooting or the like.
