Problems solved by technology

[0006] However, when considering, for example, an imaging device in which a high-pixel imaging element and a standard-pixel imaging element are accommodated in a single housing and switches the imaging elements by time division, in the above-mentioned prior art, the signals of the imaging elements are separately processed by time division. Therefore, the signal processing time allocated to each imaging element is halved, and the problem of lower dynamic resolution when using the above-mentioned surveillance camera or stereo camera is unavoidable.

Embodiment 1

[0024] FIG. 1 is a block diagram showing an imaging device according to a first embodiment of the present invention.

[0025] The first imaging device (hereinafter referred to as CCD) 101 and the second CCD 102 driven by the synchronization pulse generation module 105 output the subject image as an image signal, and the output 2 The signals are synthesized and transformed into one signal. Furthermore, after the converted signal is aggregated into signals of several lines by the line delay control module 106 and the line memory 107, the signals are processed by the exposure control module (hereinafter referred to as the AE control section), the focus control module (hereinafter referred to as the AF control module) The control unit) respectively performs exposure control and automatic focus control. In addition, in the white balance control module (hereinafter referred to as the WB control module), the white balance control is performed with the signal processed by the color s...

Embodiment 2

[0030] As a second embodiment, FIG. 3 shows that the signal from the first CCD and the signal from the second CCD are combined and converted into one signal, and AE control and AF control are performed using the signal from either the first or second CCD. , The signal flow chart of WB control.

[0031] 308 is a signal converted into one signal obtained by synthesizing two signals output from two CCDs for each horizontal one line by a two-line one-line conversion module. 309 is an AE control module for performing AE control using only one of the CCD signals converted into one signal synthesized for each of the above-mentioned horizontal 1 lines. 310 is an AF control module for performing AF control using only one CCD signal of one signal converted from the synthesis of each of the above-mentioned one horizontal lines. 313 is a WB control module for performing WB control using only one of the CCD signals converted into one signal synthesized for each of the above-mentioned hori...

Embodiment 3

[0034] As a third embodiment, FIG. 4 shows that AE control, AF control, and WB control are performed using the average of two CCD signals included in one signal converted from a signal obtained by combining the signal from the first CCD and the signal from the second CCD. signal flow chart.

[0035] 408 is a 2-line 1-line conversion module that converts 2 signals output from 2 CCDs to each horizontal 1-line and then converts it into one signal. 409 is an AE control module that performs AE control by using one signal converted from the synthesis of the above-mentioned two horizontal 1-wires. 410 is an AF control module that performs AF control by using a signal converted from the synthesis of each horizontal line. 413 is a WB control module for WB control using a signal converted from the synthesis of each of the above-mentioned horizontal 1 lines.

[0036] the above, and the first embodiment's figure 2 Similarly, the signal converted into one signal by the 2-wire-1-wire con...

Abstract

The object of the present invention is to provide a small-sized imaging device, which is composed of: two imaging elements; A conversion module; a line memory for converting a signal from the conversion module; a line delay module for storing a signal output from the conversion module; a line memory for storing a signal of the line delay module; an exposure control unit; an automatic focus control Department; white balance control unit; color signal processing module; brightness signal processing module; arithmetic processing module for stereo camera processing. It converts output signals from multiple imaging elements into one signal and performs camera signal processing.

Description

technical field [0001] The present invention relates to imaging devices. Background technique [0002] As background art in this technical field, there is, for example, JP-A-7-7653. [0003] In this gazette, it is stated that "the object is to process signals from a plurality of imaging elements with less signal processing devices than the imaging element, to provide a more power-saving, smaller, and lower-priced device than the prior art." Multiple-input and multiple-output cameras". In addition, as a structure, it is also described that "a first signal selection circuit that connects n solid-state imaging elements to k signal processing devices, k signal processing devices, and connects k signal processing devices to m output An imaging device composed of a second signal selection circuit connected to the device, a control circuit for controlling the first and second signal selection circuits and a signal processing device". [0004] As one aspect of the camera, it is c...
