Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Please refer to figure 1 , figure 1 It is the basic structure of an image signal processing system for physiological information measurement in the present invention. The image signal sensing unit 110 converts the image light signal of the subject 100 into an original image signal 160, and then transmits it to the image signal processing unit 120 and the physiological signal. The processing unit 130 and the image signal processing unit 120 can perform various adjustments on the original image signal 160, including but not limited to white balance adjustment, exposure adjustment, focus adjustment, gamma correction (Gamma Correction), edge enhancement, hue and saturation adjustment And noise reduction, adjusted and sent to the post-stage, such as display screen, or storage device, etc. The physiological signal processing unit 130 performs vario...

Abstract

The invention discloses an image adjusting method and an image signal processing system for physiological information measurement. The method comprises following steps: converting at least one opticalsignal of a testee received by an image signal sensing unit into an image signal; analyzing the image signal to obtain a physiological signal of the testee; optimizing the physiological signal of thetestee so as to determine one feedback control signal or a control signal; and according to the feedback control signal or the control signal, adjusting the setting of the image signal sensing unit or an image signal processing unit.

Description

technical field [0001] The invention relates to an image adjustment method and an image signal processing system for physiological information measurement. Background technique [0002] Existing image processing systems usually use an image signal processor as the core of the image processing element to optimize image quality automatically and at high speed, such as removing image noise, auto-focus, auto-exposure, and auto-white balance. Existing image processing systems mostly use human vision system (Human Vision System, HVS), digital camera display, image compression storage, etc. as optimization indicators for adjusting image quality. For example, based on the medical analysis of the human eye structure and the understanding of visual psychology, the differences in the sensitivity of the human eye to light brightness, color contrast, timing or spatial changes are used as indicators for adjusting image quality. Therefore, the existing image processing system uses a mathe...
