Method, system and software for displaying medical images

In a system for displaying medical images, a first linear array of medical images representing multiple views of a patient taken approximately contemporaneously may be displayed. The images may automatically be ordered within the array based on the represented views. A second linear array of medical images adjacent to the first linear array may contemporaneously be displayed. The images of the second linear array may represent the same views of the patient as in the first linear array taken approximately contemporaneously but at an earlier time from the images of the first linear array. Like views of the patient may be aligned as between the first linear array and the second linear array. Correlation of features between images may thus be facilitated. Alternatively, one or more principal views and one or more non-principal views of a patient in a set of medical images may be identified. Each principal view may automatically be displayed in a particular size on a separate display of an array of displays, while each non-principal view may automatically be displayed on the remaining display or displays of the array in a smaller size.

Methods and systems for sub-pixel rendering with gamma adjustment

Thus, methods and systems for sub-pixel rendering with gamma adjustment are disclosed. The gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the algorithms to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques disclosed with gamma adjustment can be optimized for a display device gamma to improve response time, dot inversion balance, and contrast because gamma correction and compensation of the sub-pixel rendering algorithm provides the desired gamma through sub-pixel rendering. These techniques can adhere to any specified gamma transfer curve.

Multiple exposure high dynamic range image capture

Techniques for creating a High Dynamic Range (HDR) image within a consumer grade digital camera from a series of images of a scene captured at different exposure levels, and displaying the HDR image on the camera's built-in display are provided. The approach employs mixing images of the series to incorporate both scene shadow and highlight details, and the removing of “ghost” image artifacts appearing in the mixed HDR image resulting from movement in the scene over the time the series images are captured.

Cell lines for each character are remapped to provide expanded cell lines. The flat panel apparatus includes a video memory for storing the character code, attribute data and font data, a character generator for generating character font data based on the character code, a lookup table for providing expanded cell lines, and an attribute controller for combining the font data and the attribute data for output to a flat panel display.
