Field of the Invention The present invention relates to a digital image observation apparatus, and more particularly to a digital image observation apparatus having a color adjustment function. [Prior Art] p ^ With the advancement of technology, it has become very common for users to take pictures with digital cameras. With the development of digital camera technology, the captured image files are stored in digital form on a general storage device, such as a hard disk or a memory card, which can be viewed by the user on the display. Some monitors (such as digital TVs or digital photo frames) now have the ability to access the contents of a storage device (such as a memory card), allowing users to view digital images more easily. However, during viewing, the user can change the visual effect of the displayed color of the digital image. (In the case of the first technique, the user must dream of adjusting the digital image. Help computer software to make adjustments. However, the method of using computer software adjustment is too complicated, and it is not easy for ordinary users to operate. Therefore, it is necessary to invent a new image observation device to solve the problem that the prior art is inconvenient to adjust. The main purpose of the present invention is to provide a digital image observation device having the effect of changing the color of a digital image. 200912882 To achieve the above purpose, the image processing unit 71, the control parameter storage U, the reading The Ϊ observation device includes a display panel and a control interface unit. The functions of the control unit, the time control single parameter storage unit, the reading plate, the image processing unit, and the control are as follows: image processing day: the control unit and the display panel are mutually The system has a number of storage units.

The image observation device can be further step-by-step. 7^^4 time control unit, with the function of controlling the time flow 匕0 " The digital image observation device of the present invention performs the steps of: the user can select the read digital image by using the 2-interface interface, and Selecting the digital image and the display mode; the image processing unit can read the digital image in the storage medium via the reading unit, and read the relevant parameters according to the processing effect selected by the user, and process the digital image. To form a processed digital image, and display the processed digital image on the display panel. [Embodiment] In order to enable the reviewing committee to better understand the technical content of the present invention, the specific implementation is more specific The following is a description of the structure of the digital image viewing device of the present invention. The digital image viewing device 1 of the present invention may be a digital television or its 200912882 digital type. The display 'but this _ Ming You and I,, l 丄 digital image observation device 1 〇 includes image processing.

The reading unit 23 and the time-controlled number are stored earlier than tb, and /gg „70 can be set on a wafer 20 δ. The image processing unit 21 is used to control the operation of all the units in the device 1g. Control parameter storage unit storage-table number wire device 1G N-memory device for storing and processing i-yuan? 1 ^/number table 221 can store complex parameter values, image Yun Zengfu # take parameter table 221 parameters Value for color conversion 3 ° = stored plural parameter value will be followed by a detailed H to take early 23 to read the data of the storage device 31, storage L, memory card or mobile hard disk, etc. The invention also controls the time control unit (4) to control a time flow to prevent the Fig. 25's early 70 1 from appearing early or a plurality of digital images on the display panel =. The display panel 25 is used to display digital digits:: meta = member digital image before or after processing. The image processing method of the early U will be described in detail later. The control interface unit 26 is operative to provide a control device for the user to operate: the image processing unit 21 of the digital image viewing device 10, and the operation to be performed by the unit 21. The control interface unit 26 J is controlled by wired or wireless data transmission splitting 21, and the invention is not limited thereto. Thousands 200912882 won another: ' ί: As shown in Figure 2, Figure 2 is the intention of the digital image of the present invention. On the display panel 25, it is also possible to display the effect of the second leopard dream (4) m, so that the user can more easily control the interface unit 26. Please refer to Figure 3 for the contents of the chart 221. Fig. 3 is a schematic diagram of the in-ship parameter table of the present invention. The parameter table 221 can store the processing effect of the complex=color shirt conversion operation. As shown in the figure, “ν_” and r. ^”4 each of the four movements 4 have their corresponding parameter values, and in this example, the color deviation is Shift adjustment moxibustion number dri are wide values in this application only s, eight books Γ 2 and color saturation adjustment parameters do not represent the parameters pn~p71, gin = P1; ~ P73 in Figure 3. It should be noted that In Fig. 3, the parameters are: two need:: the effect and the type of the parameter are changed, and the reference is made to the interface unit 26 of the present invention, and the digital image of the present invention is observed with reference to FIG. 4A-4B. The flow chart is set out. It should be noted here that the following describes the method for observing the m image and the port image of the digital image of the invention according to the number I observation device H). Limited. 〃, use the digital image viewing device. First, proceed to step 401: Determine the image processing mode. The control interface unit 26 is configured to select a display mode to be performed. The processing effect of the line is, and the effect is selected for the selection. In step 402, a digital image is read. 200912882 After the user issues an instruction, the image processing unit 21 reads the designated digital image in the storage device 31 via the reading unit 23. And proceeding to step 403: reading a parameter table 221. The image processing unit 21 reads the relevant parameters for the processing effect selected by the user. Taking the parameter table 221 in FIG. 3 as an example, if the user selects the effect of "Red", the image processing unit 21 reads the parameters P21, P22, and P23 to perform color conversion operations on the digital image. The flow of the color conversion operation will be described in detail later. f The order of step 402 and step 403 described above may be interchanged, and the present invention is not limited to this order. If the image processing unit 21 can load its processing program, steps 402 and 403 can also be processed simultaneously. And proceeding to step 404: controlling a time flow. If the user requests to display a plurality of digital images, the time control unit 24 controls the time flow processed by the image processing unit 21 to prevent the multiple digital images from being continuously displayed on the display panel 25 to cause a signal. confusion. The time flow is also determined by the user via the control interface (" element 26.) Next, step 405 is performed to determine whether the signal value of the digital image is a luminance-chroma value. To simplify the image processing unit 21 In the calculation method, the present invention performs color signal calculation under the color space of Luminance-Chrominance, that is, using the value of luminance and chroma YC1C2, or YCbCr value for calculation. It is necessary to first determine whether the signal value of the digital image is a luminance-chroma value. If the signal of the digital image 200912882 is a luminance-chroma value, proceed directly to step 407. If not, proceed to step 406. Step 406: The signal value of the digital image is changed to the luminance-chroma value. When the signal value of the digital image is in the color space of the RGB value, the signal value of the digital image is brought into the formula:
Ύ " ell c\2 cl3 ~R C1 — c2l c22 c23 G C2 c31 c32 c33 B Γ : 其中ell到c33係轉換係數。由於此轉換的公式已經 被熟悉此項技藝者所廣泛使用，故在此不再贅述。如此一 來即可得到YC1C2的值。 轉換完畢後即進行步驟407:對該數位圖像進行處理以 形成一處理過之數位圖像。Ύ " ell c\2 cl3 ~R C1 — c2l c22 c23 G C2 c31 c32 c33 B Γ : where ell to c33 is the conversion factor. Since the formula for this conversion has been widely used by those skilled in the art, it will not be repeated here. In this way, the value of YC1C2 can be obtained. After the conversion is completed, step 407 is performed: processing the digital image to form a processed digital image.
圖像處理單元21即對數位圖像進行一低複雜度演算法 運算。其中低複雜度演算法係只將彩度的值C1與C2的值 套入色彩偏移調整參數dCl、dC2與色彩飽和度調整參數S 〇 進行運算。亮度Y則不予改變。其演算之公式如下：The image processing unit 21 performs a low complexity algorithm operation on the digital image. The low complexity algorithm only calculates the values of the chroma values C1 and C2 into the color shift adjustment parameters dCl, dC2 and the color saturation adjustment parameter S 〇 . The brightness Y is not changed. The formula for its calculation is as follows:
Cl_new^C\^S + dC\ C2__ = C2**S + c/C2 若以使用者選擇「Red」之效果為例，其中色彩飽和度 調整參數S為參數P23，色彩偏移調整參數dCl為參數 P21，色彩偏移調整參數dC2為參數P22。如此一來即可得 到新的彩度值Cl_new與C2_new。由於只對彩度值C1與 C2進行計算，因此相較於在RGB值的表示法下需同時計 算三種數值，本發明的方式可以更節省數位圖像觀察裝置 200912882 ίο中硬體或軟體的資源。最後即可得到處理過之數位圖像 的亮度-彩度值。 接者進行步驟4 0 8 :將該處理過之數位圖像之訊號值轉 換為RGB值之形式。 由於需將處理過之數位圖像顯示於顯示面板25上，但 部份顯示面板25不能直接處理亮度-彩度值的訊號，因此 需再將亮度-彩度值轉為RGB值之形式。其轉換公式如下：Cl_new^C\^S + dC\ C2__ = C2**S + c/C2 If the user selects the effect of "Red" as an example, the color saturation adjustment parameter S is parameter P23, and the color offset adjustment parameter dCl is Parameter P21, color offset adjustment parameter dC2 is parameter P22. In this way, new chroma values Cl_new and C2_new can be obtained. Since only the chroma values C1 and C2 are calculated, the method of the present invention can save the resources of the hardware or software in the digital image observation device 200912882 ίο compared to the calculation of the three values at the same time in the representation of the RGB values. . Finally, the brightness-chroma value of the processed digital image is obtained. The receiver performs step 4 0 8 : converting the signal value of the processed digital image into the form of RGB values. Since the processed digital image needs to be displayed on the display panel 25, but some of the display panel 25 cannot directly process the luminance-chroma value signal, the luminance-chroma value needs to be converted into the RGB value. The conversion formula is as follows:
Rc d\\ d\2 d\3~ _ Y Gc — d2\ dll d23 Cl new Be d3\ d32 d33 C 2 new 其中dll到d33係轉換係數。同樣地，由於此轉換的 公式已經被熟悉此項技藝者所廣泛使用，故在此不再贅 述。藉此即得到RGB值的處理過之數位圖像。 最後進行步驟409 :顯示該處理過之數位圖像。 最後在顯示面板25上顯示出處理過之數位圖像。若在 步驟401中使用者選擇了多個數位圖像，此時顯示面板25 就會依序顯示其多個數位圖像。 此處需注意的是，本發明之數位圖像觀察之方法並不 以上述之步驟次序為限，只要能達成本發明之目的，上述 之步驟次序亦可加以改變。 綜上所陳，本發明無論就目的、手段及功效，在在均 顯示其迥異於習知技術之特徵，懇請貴審查委員明察， 早曰賜准專利，俾嘉惠社會，實感德便。惟應注意的是， 上述諸多實施例僅係為了便於說明而舉例而已，本發明所 200912882 主張之權利範圍自應以申請專利範圍所述為準，而非僅限 於上述實施例。 【圖式簡單說明】 圖1係本發明數位圖像觀察裝置之架構圖。 圖2係本發明數位圖像觀察裝置之顯示狀態之示意圖。 圖3係本發明數位圖像觀察裝置内參數表之示意圖。 圖4A-4B係本發明數位圖像觀察裝置之操作流程圖。 Π 【主要元件符號說明】 數位圖像觀察裝置10 晶片20 圖像處理單元21 控制參數儲存單元22 參數表221 讀取單元23 顯示面板2 5 時間控制單元24 控制介面單元26 儲存裝置31 色彩偏移調整參數dCl、dC2Rc d\\ d\2 d\3~ _ Y Gc — d2\ dll d23 Cl new Be d3\ d32 d33 C 2 new where dll to d33 is the conversion factor. Similarly, since the formula for this conversion has been widely used by those skilled in the art, it will not be described here. Thereby, the processed digital image of the RGB value is obtained. Finally, step 409 is performed: displaying the processed digital image. Finally, the processed digital image is displayed on the display panel 25. If the user selects a plurality of digital images in step 401, the display panel 25 displays the plurality of digital images in sequence. It is to be noted that the method of observing the digital image of the present invention is not limited to the above-described order of steps, and the order of the above steps may be changed as long as the object of the present invention can be attained.
