Problems solved by technology

image 3 is directed at Figure 1A It is obtained by performing image partitioning. However, due to an inappropriate threshold value or interference from ambient light, the hand image Img_hs becomes an incomplete image after partitioning, so the size and position of the hand image will also be misjudged

Embodiment Construction

[0037] Figure 4 , Figure 5 and Figure 6 A schematic diagram of a method for determining an image partition threshold value according to an embodiment of the present invention is drawn. Such as Figure 4 As shown, when the mechanism for adjusting the image partition threshold value is activated, a plurality of image regions will be defined for the image sensed by the image sensor, and then the corresponding partial image partition thresholds will be determined by these image regions. value (eg Figure 4 Partial image partition threshold_1, partial image partition threshold_2...local image partition threshold_n) in Then, the image is partitioned using these partial image partition thresholds to form partitioned images Img_s1 , Img_s2 . . . Img_sn. Then, score the partitioned images Img_s1, Img_s2 . . . Img_sn, and then select the local image partition threshold corresponding to the partitioned image with the highest score as the required image partition threshold accordi...

Abstract

The invention discloses an image partition threshold value determination method. The method comprises the following steps of defining plural image areas in a first sensing image; according to first and second image areas in the image areas, determining corresponding first and second local image partition threshold values; using the first and second local image partition threshold values to execute first and second image partition motion to the first sensing image respectively so as to acquire first and second partition rear images; and according to the first and second partition rear images, determining which one of the first and second local image partition threshold values to be taken as a first image partition threshold value of an image processor.

Description

technical field [0001] The present invention relates to an image partition threshold determination method, an image sensing system, a gesture judgment method and a gesture judgment system, in particular to an image sensing system, a gesture judgment method and a gesture judgment system capable of dynamically changing the image partition threshold. Background technique [0002] More and more electronic devices (such as smart phones and smart TVs) can perform different functions according to user's gestures. However, before performing such operations, the position of the hand must be detected first, so that the gesture can be correctly judged. Generally speaking, if the depth detector is not used, in order to determine the shot image from the images captured by the image sensor, image segmentation will be performed on the image first. A more common image partition method is to partition according to brightness. [0003] Figure 1A and Figure 1B A schematic diagram of perfo...
