Description

具有定焦鏡頭的手機 Mobile phone with fixed focus lens

本發明涉及一種通訊設備，尤其涉及一種具有定焦鏡頭的手機。 The invention relates to a communication device, in particular to a mobile phone with a fixed focus lens.

QR(Quick Response)碼是二維條碼的一種，QR碼可比普通條碼儲存更多資訊且佔用面積小，因此越來越受到商家以及消費者的歡迎。另外，由於手機的普遍使用，通常將QR碼識別功能集成在手機內。 QR (Quick Response) code is a kind of two-dimensional bar code. QR code can store more information than ordinary bar code and occupy a small area, so it is more and more popular among merchants and consumers. In addition, due to the widespread use of mobile phones, the QR code recognition function is usually integrated into the mobile phone.

識別QR碼時，通常使用調焦鏡頭對QR碼進行微距拍攝，然後藉由特定的解碼軟體對QR碼解碼，從而得到準確的QR碼資訊。然而，先前手機上普遍安裝的是定焦鏡頭，如果改用定焦鏡頭對QR碼進行拍攝，需要短焦距才能夠獲得清晰的圖像。而由於紅光和綠光的焦距較藍光遠，因此在近距離拍攝時，紅光訊號和綠光訊號在成像面上的圖像不如藍光清晰。而先前使用定焦鏡頭拍攝QR碼的技術中，通常獲得QR碼的紅光、綠光以及藍光訊號，使得紅光和綠光的成像效果影響了整體的清晰度，從而降低識別準確度。 When the QR code is recognized, the QR code is usually macro-photographed using a focus lens, and then the QR code is decoded by a specific decoding software, thereby obtaining accurate QR code information. However, the fixed lens is commonly installed on mobile phones. If you use a fixed focus lens to shoot the QR code, you need a short focal length to get a clear image. Since the focal lengths of red and green light are farther than blue light, the image of the red and green signals on the imaging surface is not as clear as the blue light when shooting at close range. In the prior art of using a fixed-focus lens to capture a QR code, the red, green, and blue signals of the QR code are usually obtained, so that the imaging effects of the red and green light affect the overall definition, thereby reducing the recognition accuracy.

有鑒於此，有必要提供一種提高識別準確度的具有定焦鏡頭的手機。 In view of this, it is necessary to provide a mobile phone having a fixed focus lens that improves recognition accuracy.

一種具有定焦鏡頭的手機，其具有資訊碼識別模式。所述手機包 括一定焦鏡頭、一影像感測器、至少一圖像處理器以及一資訊碼識別裝置。所述定焦鏡頭用於收集所述資訊碼發射出來的可見光。所述影像感測器用於感測所述可見光並分別輸出紅、綠、藍三色資訊碼圖像訊號供所述圖像處理器進行處理。所述資訊碼識別裝置用於獲得所述圖像處理器處理後的圖像並進行解碼識別。所述圖像處理器包括一控制模組，所述控制模組用於當所述手機切換至資訊碼識別模式時，根據所述影像感測器與所述圖像處理器之間是否導通來控制所述圖像處理器僅獲取所述藍色資訊碼圖像訊號。 A mobile phone with a fixed focus lens, which has an information code recognition mode. The mobile phone bag A fixed focus lens, an image sensor, at least one image processor, and an information code recognition device are included. The fixed focus lens is used to collect visible light emitted by the information code. The image sensor is configured to sense the visible light and output red, green, and blue color code image signal signals for processing by the image processor. The information code identifying device is configured to obtain an image processed by the image processor and perform decoding and recognition. The image processor includes a control module, and the control module is configured to: according to whether the image sensor is connected to the image processor when the mobile phone switches to the information code recognition mode Controlling the image processor to acquire only the blue information code image signal.

與先前技術相比，本發明的具有定焦鏡頭的手機，根據藍光較紅光以及綠光的焦距短，在經過定焦鏡頭後能夠在近物距獲得清晰圖像的原理，藉由一控制模組使圖像處理器僅獲取資訊碼圖像中的藍光訊號進行處理，並供所述資訊碼識別裝置識別，從而能夠獲得清晰的資訊碼圖像，提高識別準確度。 Compared with the prior art, the mobile phone with the fixed focus lens of the present invention has a short focal length according to the blue light and the green light, and can obtain a clear image at a near object distance after passing through the fixed focus lens, with a control The module enables the image processor to obtain only the blue light signal in the information code image for processing, and is recognized by the information code recognition device, thereby obtaining a clear information code image and improving recognition accuracy.
