The display pixel (resolution) of the display module 10 is m×n (width×height), m is a display pixel in the horizontal direction of the display module 10, and n is a display in the vertical direction of the display module 10. Pixel. The image pixel of the face image 11a is M×N pixels, M is an image pixel in the horizontal direction of the face image 11a, and N is an image pixel in the vertical direction of the face image 11a.
請結合圖3，當M≧m，N≧n時，該放大模組16將該人臉圖像11a放大並將該放大後之人臉圖像11a全屏顯示於該顯示模組10。也就是說，該選擇之人臉圖像11a之圖像像素不小於該顯示模組10之顯示像素時，該人臉圖像11a放大後之圖像範圍Y1與該顯示模組10之顯示範圍L一致。 Referring to FIG. 3, when M≧m, N≧n, the zoom module 16 enlarges the face image 11a and displays the enlarged face image 11a in full screen on the display module 10. In other words, when the image pixel of the selected face image 11a is not smaller than the display pixel of the display module 10, the enlarged image range Y1 of the face image 11a and the display range of the display module 10 L is consistent.
請結合圖4，當M<m，N≧n時，該放大模組16將該人臉圖像11a在垂直方向上全屏放大，而在水平方向上放大至該顯示模組10之M/m倍。該人臉圖像11a放大後之圖像範圍Y1顯示在該顯示範圍L中之表現為：該圖像範圍Y1在水平方向受到變形。 Referring to FIG. 4, when M<m, N≧n, the zoom module 16 enlarges the face image 11a in the vertical direction and enlarges to the M/m of the display module 10 in the horizontal direction.

N/n times the range. That is, if the image pixel in the horizontal direction of the selected face image is not smaller than the display pixel in the horizontal direction of the display module, the image pixel in the vertical direction of the selected face image is smaller than the image pixel. Displaying the display pixels in the vertical direction of the module, and enlarging the selected face image to be consistent with the horizontal display range of the display module in the horizontal direction and at a first scale in the vertical direction, The first ratio is: the image pixels in the vertical direction of the selected face image are smaller than the display pixels in the vertical direction of the display module.
步驟S26，當M<m，N≧n時，將該人臉圖像放大為在垂直方向上與該顯示模組之垂直顯示範圍一致，而在水平方向上放大至該顯示模組之水平顯示範圍之M/m倍。即，若該選擇之人臉圖像之水平方向上之圖像像素小於該顯示模組之水平方向上之顯示像素，而該選擇之人臉圖像之垂直方向上之圖像像素不小於該顯示模組之垂直方向上之顯示像素，則將該選擇之人臉圖像放大為在垂直方向上與該顯示模組之垂直顯示範圍一致，而在水平方向上以一個第二比例放大，該第二比例為：該選擇之人臉圖像之水平方向上之圖像像素比該顯示 模組之水平方向上之顯示像素。 Step S26, when M<m, N≧n, the face image is enlarged to be consistent with the vertical display range of the display module in the vertical direction, and enlarged to the horizontal display of the display module in the horizontal direction. M/m times the range. That is, if the image pixel in the horizontal direction of the selected face image is smaller than the display pixel in the horizontal direction of the display module, the image pixel in the vertical direction of the selected face image is not smaller than the image pixel. Displaying a display pixel in a vertical direction of the module, the selected face image is enlarged to be perpendicular to the vertical display range of the display module in the vertical direction, and enlarged in a horizontal direction by a second ratio, The second ratio is: the image pixel ratio in the horizontal direction of the selected face image is greater than the display The display pixels in the horizontal direction of the module.
步驟S27，在一個預定時間內持續顯示放大後之該選擇之人臉圖像。 In step S27, the selected face image after the enlargement is continuously displayed for a predetermined time.
步驟S28，在該預定時間結束後選擇下一個人臉圖像。及返回步驟S22。 In step S28, the next personal face image is selected after the predetermined time ends. And returning to step S22.
