Scenes from motion pictures to be colorized are broken up into separate elements, composed of backgrounds / sets or motion / onscreen-action. These background and motion elements are combined into single frame representations of multiple frames as tiled frame sets or as a single frame composite of all elements (i.e., both motion and background) that then becomes a visual reference database that includes data for all frame offsets which are later used for the computer controlled application of masks within a sequence of frames. Each pixel address within the visual reference database corresponds to a mask / lookup table address within the digital frame and X, Y, Z location of subsequent frames that were used to create the visual reference database. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods. The gray scale determines the mask and corresponding color lookup from frame to frame as applied in a keying fashion.

When a shutter release button of an image capturing apparatus is half pressed, an exposure time t is determined by a normal AE function. Then, if a shutter release button is fully pressed, an image is captured with the exposure time t, and the captured image is stored in a frame memory. At the same time, a color-coding circuit color-codes the captured image according to luminance thresholds, and the color-coded image is displayed on an LCD. If a user selects a color of an area equivalent to a main subject with reference to the color-coded image, a dynamic range, gamma characteristics, and the like of the image are determined so that the area in the selected color can have a correct luminance. The image is corrected accordingly, and image data acquired by the correction is stored in a recording part.

Motion picture scenes to be colorized / depth enhanced (2D→3D) are broken into separate elements, backgrounds / sets or motion / onscreen-action. Background and motion elements are combined separately into single frame representations of multiple frames which becomes a visual reference database that includes data for all frame offsets used later for the computer controlled application of masks within a sequence of frames. Each pixel address within the database corresponds to a mask / lookup table address within the digital frame and X, Y, Z location of subsequent frames. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods, including automated mask fitting of all masks or single masks in an entire frame, bezier and polygon tracing of selected regions with edge detected shaping and operator directed detection of subsequent regions. Colors and / or depths are automatically applied to masks throughout a scene from the composite background and to motion objects.

Processes for selecting, manipulating and arranging data points or pixels derived from information bearing signals are useful to reduce the bandwidth of, or improve the perceived quality of, such a signal as transmitted and displayed. The techniques utilize time-varying sampling schemes and take into account the characteristics of the human visual system. For each information frame, a subset (3) of all possible data points (1) is selected (2). A further subset of active data points (5) is selected (4) for which data will actually be sampled. The active points (5) are further divided (6) into points for which a value will be transmitted (x-points) (7) and points which will be sampled but for which no separate value will be transmitted (o-points) (8). A mathematical association between the x-points and o-points is made (9) and new values to be transmitted are calculated for the x-points (10). The parameters of the selection and association processes are varied in a non-trivial manner and the, now modified, cycle repeated (11) for subsequent data frames. In particular, the techniques may be used to process a high-definition television signal prior to its storage, or transmission over a low-bandwidth channel.

In a digital camera that can perform print designation, a print designation file for writing jobs for printing is prepared in a memory card in which image data is recorded, and information for specifying a file to be printed (FILE_ID), file identifying information for identifying whether the file to be printed is a moving image file or a still image file (FILE_TYPE), and information for specifying a scene to be printed in the moving image if the file to be printed is the moving image file (FRAME_NUM), are stored in the print designation file. A printing device reads the printed designation file from the memory card, then takes out the image data to be printed from the memory card in accordance with the read information and executes printing. Thus, it is possible to preform the print designation of the specified image in the moving image without wasting the memory capacity in the recording medium.

A monochromatic image of which the number of gradation levels (for example, 1024 levels) is greater than that (for example, 256) of a monochromatic image viably handled by an operating system (OS) (13) is converted into a color image which is then received by the OS (13). The color image to be handled by the OS (13) is embraced by the number of available colors (for example, 16,777,216) and can thus be released out directly. The color image released from the OS (13) is then converted into a monochromatic image of which the number of gradation levels (for example, 1021 or 1024) is greater than that (for example, 256) of a monochromatic image viably handled by the OS (13) before displayed. Accordingly, the monochromatic image can be displayed at multiple gradation levels which exceed the gradation limit of any conventional operating system without drastically modifying the hardware or software.

A digital image capturing module assembly and method of fabricating the same is proposed, which is used for the assembly of a digital image capturing module from a photosensitive printed circuit board and a lens holder. The proposed assembly method is characterized by the provision of a ring plane between focusing plane and corner-located aligning posts on the lens holder so as to allow the coated adhesive layer over the ring plane to provide a sealed light impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder.

A method for colorization of images is presented. The method comprises the following steps: Displaying an image (102); applying multiple color markings (at least two colors are different) to the displayed image (104); automatically coloring the image by applying a constrained optimization to a cost function that is responsive to the marked colors and the intensity differences of the neighborhoods of some of all of the pixels (106); the resultant image is subsequently stored (110), displayed (108), or transferred (112).

A low-resolution image having a low resolution and low frequency band is generated from an image sensed by using a single board color image sensor, and pseudo color suppression and color noise suppression are performed on each of the image and low-resolution image. The resolution of the low-resolution image is then restored, and weighted combination is performed on this image and the former image. If it is determined that a pixel of interest belongs to a region where a pseudo color is generated, a MIX ratio calculator (205, 225) for calculating a ratio coefficient for combination calculates a ratio coefficient by which a color signal of a pixel of the low-resolution image having the restored resolution is the result of the weighted combination. This makes it possible to effectively suppress both a pseudo color and color noise.

The invention relates to a method of reproducing a gray scale image (1) in colors on a color monitor (6), in which method each shade of gray (2) is assigned, using a look-up table (4, 5), a given output value (R, G, B) for driving the electron guns (8R, 8G, 8B) of the color monitor. Assignment is performed in such a manner that a given color deviation is imparted to successive shades of gray, which deviation enables differentiation of the shades of gray by a human observer without such deviations becoming disturbing. Consequently, the information concerning the optical density of the original gray scale image (1) is preserved; this is important notably for the interpretation of medical images. Additionally, the special display properties of the monitor (6) and / or the ambient circumstances can be taken into account in the look-up table (4, 5) in order to optimize the reproduction of the gray scale image.
