The embodiment of the invention discloses an image acquisition method and device, electronic equipment and a medium. The method comprises the steps of determining respective current brightness values of at least two target areas in an image obtained by performing image acquisition on a target object by an image acquisition device; determining target gain values associated with the current brightness values of the at least two target areas according to the association relationship between the brightness values and the gain values; adjusting respective gain values of at least two photosensitive areas in an image collector according to the target gain value, and controlling the image collector to perform image collection on the target object again; wherein the at least two photosensitive areas are photosensitive areas corresponding to the at least two target areas. According to the scheme, the target gain values are specifically determined for the different target areas in the image, the respective gain values of the different photosensitive areas corresponding to the different target areas are determined, and image acquisition is performed based on the different gain values, so that the image quality of each target area in the image is improved at the same time.

    本申请实施例公开了一种图像采集方法、装置、电子设备及介质。该方法包括:针对图像采集器对目标对象进行图像采集得到的图像,确定所述图像中至少两个目标区域各自的当前亮度值;根据亮度值与增益值的关联关系,确定至少两个目标区域各自的当前亮度值关联的目标增益值;根据所述目标增益值,对图像采集器中至少两个感光区域各自的增益值进行调节,并控制所述图像采集器再次对所述目标对象进行图像采集;其中,至少两个感光区域为与至少两个目标区域对应的感光区域。上述方案通过针对图像中的不同目标区域,针对性地确定目标增益值,并确定与不同目标区域对应的不同感光区域各自的增益值,基于不同的增益值进行图像采集,从而同时提高图像中各目标区域的图像质量。
