Problems solved by technology

However, the way to zoom out the captured image will make it difficult to find the target because the target image is too small
In addition, if the captured image is not zoomed out, only a small part of the captured image can be displayed, which is also not conducive to the search of the target

Embodiment Construction

[0019] Please refer to FIG. 1, which is a block diagram of a target searcher according to a preferred embodiment of the present invention. In the figure, the target searcher 100 includes: an image capturing unit 110, an image processing unit 120, an image display unit 130, and an eye tracking unit 140. The image processing unit 120 is coupled to the image capturing unit 110, the image display unit 130, and the eye tracking unit 140. Of course, as known to those who are familiar with the art, the eye tracking unit 140 can be omitted when the preset target is selected without referring to the output of the eye tracking unit 140.

[0020] As shown in FIG. 1, the image capturing unit 110 may use different image sensors such as Charge Coupled Device (CCD) or Complementary Metal Oxide Semiconductor (CMOS) to capture remote targets. , And output an image with I×J pixels.

[0021] In this embodiment, the image 310 output by the image capturing unit 110 ( image 3 ) Or 610 ( Figure 6 The ...

Abstract

The invention relates to a target searcher and a method for processing an image thereof, which comprises an image capturing unit used for outputting an image with an I*J pixel, an image displaying unit used for displaying an image with an M*N pixel and an image processing unit. Wherein, the image processing unit can receive the image from the image capturing unit and select a presupposed target from the image and then take the selected presupposed target as a center to divide the image into a plurality of image areas; after that, each image area is reduced or enlarged by a rate parameter respectively; the image with the I*J pixel is converted into the image with the M*N pixel and is sent to the image displaying unit to be displayed, thereby achieving that the target image can be intensified by emphasis, which is in convenient for searching the image target.

Description

Technical field [0001] The invention relates to a target searcher, in particular to a target searcher capable of enhancing target images and an image processing method thereof. Background technique [0002] Target Searching Device (Target Searching Device) is an auxiliary tool used by users to search for viewing targets or aiming targets. For example, telescopes usually assist users in searching for distant viewing targets, while the sights installed on weapons and firearms Can assist the user to search for and aim at the target they want to shoot. [0003] Existing electronic telescopes or sights are equipped with an image capturing unit that can capture a target image, and an image display unit for displaying the captured image, and usually the number of pixels that the image display unit can display is The number of pixels is smaller than that of the image captured by the image capturing unit. Therefore, when the image captured by the image capturing unit is displayed on the i...
