A test chart for adjusting a camera having an optical system and an imaging element, the test chart being provided with at least one inclined surface having at least one boundary line that forms a boundary of at least one of color, shade, and brightness and that extends linearly along the inclination direction of the inclined surface, the inclined surface being disposed such that the boundary line extends linearly along the inclination direction of the inclined surface. The boundary line is inclined with respect to the optical axis of the optical system, and is not parallel to the pixel arrangement direction of the imaging element when the camera performs imaging. 一种测试图卡，其调整具有光学系统和拍摄元件的相机，该测试图卡具备至少一个斜面，斜面具有至少一个边界线，该边界线形成颜色、浓淡以及亮度中的至少某一个的边界、并沿着该斜面的倾斜方向直线状地延伸，斜面配置成，相对于光学系统的光轴倾斜，并且在相机进行拍摄时，边界线与拍摄元件的像素排列方向不平行。
