Description
Technical field
The present invention relates to a kind of electronic installation that is suitable for pick-up image and show image, hand-held electronic device and image sensing chip thereof (ELECTRIC DEVICE ADAPTED TO CAPTURE AND SHOWIMAGES, POCKET ELECTRIC DEVICE AND CHIP), particularly relate to a kind of image sensing chip of the ratio of width to height (aspect ratio) less than 1 that have, its size is the electronic installation that cooperates the image display screen size.
Background technology
In the epoch of information explosion now, the mode by information computerization can make message transmission in the world each corner, and the user is also very convenient when carrying these electronic data.With regard to image capture unit, generally be by image sensing chip pick-up image data, and institute's picked image data can be exported by the image display screen.Yet in technology now, the ratio of width to height of image sensing chip is greater than 1, and the ratio of width to height of the image display screen of general hand-held electronic device is less than 1, when therefore being presented at the picture that image sensing chip captured on the image display screen as if desire, must sacrifice the image width; Or image will be dwindled, whole image could be shown on the image display screen.
See also shown in Figure 1ly, being existing known wherein a kind of method of utilization outputs to schematic diagram on the image display screen with image sensing chip institute picked image.This image display screen 110 is that output is by image sensing chip (not shown) institute picked image 120, the ratio of width to height that generally is used for the image display screen 110 of hand-held electronic device is less than 1, yet but is greater than 1 by the ratio of width to height of image sensing chip institute pick-up image 120.When therefore being presented at image sensing chip institute picked image 120 on the image display screen 110 as if desire, must sacrifice the image 120 (being positioned at the monocline line zone of the left and right sides) in zone about being positioned at, image display screen 110 only can show the image 120 (the oblique stroke intersection region in the middle of being positioned at) that is positioned at zone line.So, be arranged in the pixel of the left and right sides of image sensing chip, the image 120 that is sensed can't output on the image display screen 110, so the pixel that is positioned at herein is as illusory, causes the meaningless increase of cost.
Perhaps, if whole image 130 will be shown on the image display screen 110, then image 130 must be dwindled, see also shown in Figure 2ly, being existing known utilization another kind method outputs to schematic diagram on the image display screen with image sensing chip institute picked image.Though all images 130 all can output on the image display screen 110, image 130 dwindles problems such as can causing the identification reduction.Moreover, image 130 after dwindling only can output to the zone line (the oblique stroke intersection region in the middle of being positioned at) of image display screen 110, can't output to the zone that is positioned at image display screen both sides about in the of 110, so but must sacrifice the viewing area (being positioned at the monocline line zone of both sides up and down) that is positioned at image display screen both sides about in the of 110.
As mentioned above, because the ratio of width to height (aspect ratio) of image sensing chip is the ratio of width to height that is different from image display screen 110, so the ratio of width to height size that causes image sensing chip institute picked image 110,130 can't cooperate the ratio of width to height size of image display screen 110, and causing, but or the problem of the part viewing area of sacrifice image display screen 110 just like the problem of preceding described dummy pixel on image sensing chip.
This shows, the above-mentioned existing electronic installation that is suitable for pick-up image and show image, hand-held electronic device and image sensing chip still have many defectives, and demand urgently further being improved.In order to solve the existing electronic installation that is suitable for pick-up image and show image, the defective of hand-held electronic device and image sensing chip, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, this obviously is the problem that the anxious desire of relevant dealer solves.
