如何理解Manual exposure: 80% MSB of image (i.e. 10bit -> 818LSB at the center of the image, G channel), no saturation in image.提到的专业词汇

这段话是在描述相机的手动曝光控制。Manual exposure表示手动曝光，即由用户手动控制相机的曝光时间、光圈和ISO等参数，而不是自动曝光。80% MSB of image表示图像的80%最高有效位（MSB），也就是图像的亮度范围在80%的最高端。10bit -> 818LSB at the center of the image表示图像是10位的，中心区域的亮度值为818。G channel表示这是绿色通道的亮度值。最后一句话no saturation in image表示图像中没有出现过曝（saturation）的情况，即没有亮度值超出了相机的动态范围。

Math problem: provision of public goods i. Under-provision of public goods in the market ii. Efficient provision: Samuelson Rule

The provision of public goods is often subject to market failures, which can lead to under-provision of these goods. This is because public goods are non-rivalrous and non-excludable, meaning that once they are provided, everyone can benefit from them and no one can be excluded from using them.

Under-provision of public goods occurs because private firms or individuals have little incentive to invest in the provision of these goods, as they cannot capture all the benefits of their investment. This leads to a situation where the total benefits of the public goods are greater than the total costs, but the private incentives to provide them are insufficient.

To address this market failure, the Samuelson Rule suggests that public goods should be provided up to the point where their marginal social benefit (MSB) equals their marginal social cost (MSC). In other words, the provision of public goods should be increased until the point where the additional benefits to society are equal to the additional costs of providing them.

By using the Samuelson Rule, society can ensure that public goods are provided at the efficient level, where the total benefits to society are maximized. This can be achieved through various mechanisms, such as government provision, subsidies, or taxes on private goods that create positive externalities.
