    摘要： A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

    摘要翻译： 一种手持式成像装置具有：数据接收器确实被配置为接收基准数据编码的图像。 该数据包括基准码的值，这是由在外部编码系统编码。参考代码值代表参考灰度级，采用了参考灰度显示功能并基于在不同的光人类视觉angepasst的感知的非线性正为其选择 水平空间频率。 因此，该成像装置具有数据转换器也被配置为访问所述基准代码值和所述成像装置的设备专用代码值之间的代码映射。 特定于设备的代码值被配置成产生灰度级做是特定于成像装置。 基于代码的映射，所述数据转换器被配置为将参考编码的图像数据转码为设备特定的图像数据时，所有这一切都被编码与所述特定于设备的代码值。
