The image-stabilizer operating member is biased toward the image-stabilizer-deactivated position so as to be positioned at the image-stabilizer-deactivated position in a free state.

A one-frame interval is divided into a light field interval and a dark field interval. In the light field interval, the display data of high tones is displayed, while in the dark field interval, the display data of low tones is displayed. This divisional display makes it possible to pseudoly display the tones of the input display data. Then, in a case that the tones of the input display data is on the lower tone side, the display data of the dark field is set to the corresponding minimum tone with the minimum luminance, while in a case that the tone of the input display data is on the higher tone side, the display data of the light field is set to the corresponding maximum tone with the maximum luminance.

The present invention has a magnetic resonance spectroscopic imaging (MRSI) method that allows collecting a complete spectroscopic image with one spectral dimension and up to three spatial dimensions in a single signal excitation. The method employs echo-planar spatial-spectral encoding combined with phase encoding interleaved into the echo-planar readout train and partial parallel imaging to reconstruct spatially localized absorption mode spectra. This approach enables flexible tradeoff between gradient and RF encoding to maximize spectral width and spatial resolution. Partial parallel imaging (e.g. SENSE or GRAPPA) is employed with this methodology to accelerate the phase encoding dimension. A preferred implementation is with the recently developed superresolution parallel MRI method, which accelerates along both the readout and phase encoding dimensions and thus enables particularly large spectral width and spatial resolution. The symmetrical k-space trajectory of this methodology is designed to compensate phase errors due to convolution of spatial and spectral encoding. This method is suitable for hyperpolarized MRSI, spatial mapping of the diffusion coefficients of biochemicals and functional MRI using quantitative mapping of water relaxation.

A down-sampling operation is performed on moving image data to reduce a sample count of the data to 1 / M times the original sample count. In the down-sampling operation, a band-limitation operation is performed on the moving image data using a low-pass filter. The low-pass filter has a stop band frequency that prevents a harmonic component having a K-th order or higher, of harmonic components generated in the down-sampling operation, from overlapping an original signal component. The down-sampling operation is then performed on the band-limited moving image data, thereby compressing the moving image data. Aliasing distortion caused by a harmonic component of a high order is controlled. The resulting compressed image is free from a substantial loss of a high-frequency component of the original signal.
